(4) 聚丙烯酰胺絮凝劑預處置普通占整個污泥處置費用較高的比例，因而，聚丙烯酰胺的優化選擇加率的合理肯定對降低污泥預處置費用相當關鍵。對選擇聚丙烯酰胺的實驗辦法的研討已展開多年，包括比阻、CST值、污泥流變性、分別液粘度、活動電流等。The synthesis and process physical properties of AM polyacrylamide: PAM is prepared by direct reaction of acrylonitrile with water under the action of framework copper catalyst, and then dried by ion exchange polymerization. The process is as follows: catalyst: catalytic hydration CH2 = CHCN + H2 humidity CH2 = CHCONH2 polymerization nCH2 = CHCONH2 - initiator - CH2CHCONH2
Industrial uses of polyacrylamide: Polyacrylamide (PAM) has high molecular weight, good water solubility, adjustable molecular weight, and can introduce various ionic groups to obtain specific properties. Low molecular weight is an effective additive or stabilizer for dispersing materials. High molecular weight is an important flocculant. It can produce hydrophilic and water-insoluble gel, which has good adhesion to many groups of surface and dissolved substances. Because of the above properties, PAM is widely used in flocculation, thickening, drag reduction, glue imitation, bonding, scale inhibition and other fields.
Anionic polyacrylamide can be used in different molecular weights according to different uses and user's requirements for product performance.
In industrial wastewater treatment, especially for suspended particles, coarser, high concentration, positive charged particles, neutral and alkaline wastewater such as iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other wastewater treatment effect is very good.
In drinking water treatment. The water source of many Waterworks in our country is low in mud and high in mineral content, which is turbid. Although it has been treated by precipitation, it still can not meet the requirements. Flocculants are needed to make the water quality clear. Many waterworks use inorganic flocculants, but the amount of inorganic flocculants is large, resulting in poor effect of sludge increase. Anionic polyacrylamide acrylamide monomer was 0.012%. The molecular weight of anionic PAM was 12.5 million and the content of acrylamide monomer was 0.013%. The concentration of two kinds of PAM is 0.05%. They are used after refrigeration for 24 hours.
(1) PAM pretreatment sludge takes lOml sludge and puts it into a 300 ml beaker. Six-unit mixers are used to mix at 1130 RPM speed for 30 seconds, and then the PAM is added to the sludge quickly and quantitatively. The PAM is stirred at lOOrpm speed for 30 seconds, then the speed of the mixer is reduced to 20-30 rpm and the slow stirring speed is 60 seconds to promote flocculation. The specific resistance of pretreated sludge, capillary water absorption time (CST), the viscosity of filtrate and the viscosity of centrifuge were measured.
(2) The specific resistance is tested by Brinell funnel according to the test method proposed by Coackley. The diameter of Brinell funnel is 80 mm. The filter paper is made of 70 mm medium speed filter paper. The vacuum degree of the test is controlled to 0.01 MPa. The experiment was repeated three times to get the average value.
(3) In order to reduce specific resistance and improve sludge dewatering effect, sludge should be pretreated before sludge dewatering. Sludge pretreatment methods include freeze-thaw pretreatment, heat treatment, acid treatment, alkali treatment, lime pretreatment and polymer flocculant pretreatment. Polymer flocculant polyacrylamide (PAM) pretreatment is the most widely used pretreatment method at home and abroad.
(6)依據CST值變化肯定PAM最投加率與測定比阻得到的最投加率分歧。并且CST值與比阻之間存在線性相關關系，比阻值越大，CST值越大，因而能夠采用CST值來近似替代污泥比阻反映污泥的脫水性能。與比阻相比，cST值測定快速、煩瑣，不但適用于實驗室研討，還可用于消費現場，快速理解污泥脫水性能的變化，使操作人員及時調楚PAM投加率，儉省藥劑費。is used as flocculant, and the dosage is inorganic flocculant. One fiftieth of the flocculants, but the effect is several times to dozens of times that of inorganic flocculants. Especially the polyacrylamide produced by our company, the residual monomers have reached the food grade (less than 0.05%), close to the advanced level abroad, non-toxic, more suitable for the treatment of drinking water, and better for the use of organic pollutants polluted river water and anionic polyacrylamide.
Polyacrylamide is used to recover lost starch and distiller's grains in starch and alcohol factories. At present, the starch in the waste water discharged by many starch factories is very high. After discharging, it affects the environment, wastes resources, and adds PAM to make starch precipitate. The precipitate is filtered by pressure filter to become cake and can be used as feed. A large number of distillers'grains in the alcohol factories are processed by this process. A certain alcohol factory in Heilongjiang Province uses polyacrylamide as flocculant, which recycles the distillers' grains and obtains a great deal of experience. Economic benefits.
Polyacrylamide is used as water shutoff agent for profile control and water shutoff in Oilfield and oil displacement agent for tertiary oil recovery.
Polyacrylamide is used as paper-making additive. PAM is widely used in paper-making. It can be used as long fiber paper-making dispersant, wet and dry reinforcing agent, retention aid, filter aid and flocculant of paper-making wastewater.
The latest type of water treatment agent polyacrylamide, when treating sewage and water in many occasions, the combination of anionic polyacrylamide and cationic polyacrylamide has a very significant and synergistic effect than using one kind of ionic polyacrylamide alone. The ability of PAM to reduce surface tension is much greater than the ability of cations or anions existing alone under the same conditions. For the requirement of low surface tension, both anionic and cationic polyacrylamide need to be used at the same time. If they are used improperly, white precipitates will be produced and the effect of using them will be lost. PAM has the characteristics of amphoteric ions. It can complete the coordination of anions and cations. There is no precipitate on the surface. Especially, it is more convenient to use PAM as a flocculant because of the complex water quality or the changeable nature of water.
The sludge used in sewage pretreatment is taken from the sedimentation tank with Qiantang River water as its source of water, and PAC is used as a flocculant in the water plant. The sludge was naturally concentrated to a solid content of 2.7%-2.8%. The organic matter content in the sludge was 12.1%, SJ content was 52.1%, Al content was determined. The content was 20.2%. There are three types of PAM: cationic, anionic and nonionic. Non-ionic PAM dissolves slowly and is generally not used for sludge pretreatment. Therefore, only two representative cationic polyacrylamides and anionic polyacrylamides are selected in the experiment. The molecular weight of cationic PAM was 12 million and the content of
(7)不管是陽離子聚丙烯酰胺絮凝劑還是陰離子聚丙烯酰胺絮凝劑，隨著投加率的增加，濾液和離心液粘度都呈現與比阻和CST值類似的變化規律，呈現了明顯的最小值，而且該最小值對應投加率與污泥比阻和CST值實率根本分歧。該加率快速、簡單，而且還有可能用作消費上在線控制PAint最 佳投加率的參數，但其在消費上的應用還需做進一步的實驗研討。
制成。混凝土是所有人工制造的物的。混凝土中四分之三是集料，然而在性等等。通常在水泥中同時使用數種摻合劑，各種不同的摻合劑在一些應用中能互相強化。
葡萄糖酸鈉可以作為摻合劑用在混凝土中，它在混凝土中的功能如下： 減水劑和緩凝劑葡萄糖酸鈉一般是單獨使用，但是也可以與其它緩凝劑如碳水化合物和磷酸鹽配合起來使用。葡萄糖酸鈉是一種結晶的粉末。是在妥善規定和控制的條件下生產出來的。此化合物是化學純的并且無腐蝕性。質量是恒定的。這些特點能保證它在應用中有可靠的和重復性的結
溶解性：極易溶于水，略溶于酒精，不能夠溶Sodium gluconate application:
Concrete is a composite material made of cement, aggregate, admixture and water. Concrete is the most abundant of all manufactured materials. Three quarters of concrete is aggregate, but the most active component in concrete is cement slurry. The properties and properties of concrete mainly depend on the properties of cement slurry. The admixtures in concrete can provide some beneficial effects, such as accelerating solidification, delaying solidification, making air bubbles, reducing water consumption and increasing plasticity, etc. Usually several admixtures are used in cement at the same time, and different admixtures can reinforce each other in some applications.
Sodium gluconate can be used as admixture in concrete. Its function in concrete is as follows: water reducer and retarder sodium gluconate are usually used alone, but can also be used in combination with other retarders such as carbohydrates and phosphate. Sodium gluconate is a crystalline powder. It is produced under the conditions of proper regulation and control. The compound is chemically pure and non-corrosive. The mass is constant. These characteristics can ensure that it has reliable and repeatable knots in application.
Solubility: extremely soluble in water, slightly soluble in alcohol, not ether
Use:
使用：
用作鋼鐵外表清洗劑：
鋼鐵外表如需要鍍缽、鍍鉻、鍍錫、鍍鎳以習慣特別用處時，如制作馬口鐵，鍍鋅板，外表鍍鉻（電度）等，其鋼坯外表均需經過嚴格清洗，使鍍層物與鋼鐵外表結實結合，這時候其清洗藥劑中添加葡萄糖酸鈉將會到達十分理想的效果。這一點已經被國際上制作馬口鐵的大公司所證實。
用作水泥摻合劑：
水泥中添加一定數量葡萄糖酸鈉后，可增加混凝土的可塑性和強度，且有阻滯作用
即推延混凝土的開始與終究凝固時期，例如添加0.15%的葡萄糖酸鈉,可將 混凝土的初凝 固時刻延伸10倍以上,也就是將混凝土的可塑時刻從幾小時延伸至幾天,而不影響其牢 度。可塑性與推遲開始凝固時刻在混凝土作業中是非常重要的問題，如在高溫度季節施工及大型的工程作業中，推遲開始凝固時刻則是個難題，葡萄糖酸鈉可滿意解 決這個問題。別的高溫時膠接油井是比較困難的，添加了葡萄糖酸鈉后的混凝土在170℃高溫下，在幾個小時內可塑，因而也能滿意解決上述問題。因而葡萄糖酸 鈉作為水泥摻合劑在國外已很多使用于重要的建筑工程，如中東的很多橋梁工程中。但是我們國內在這方面使用也還未推廣使用，據說有在造紙廢水中提煉纖維素磺 酸鈉，其效果與葡萄糖酸鈉根本是不可相提并論的。
此外還可在電鍍，膠卷制作工業中使用。
作為一種多羥基羧酸型優秀的緩蝕阻垢劑葡萄糖酸鈉，由于具有上述諸多特異性質，如能在使用技術上肯下功夫，必將會被開發成一個很大的工業。
Used as steel surface cleaner:
When steel appearance needs to be plated with bowl, chromium, tin and nickel for special use, such as tinplate, galvanized sheet and chromium plating, the billet appearance needs to be cleaned strictly, so that the coating can be firmly combined with the steel appearance. At this time, the addition of sodium gluconate in the cleaning agent will be very reasonable. Think about the effect. This has been confirmed by large international companies that make tinplate.
Used as cement admixture:
When a certain amount of sodium gluconate is added to cement, the plasticity and strength of concrete can be increased, and the effect of retardation can also be found.
That is to say, delaying the beginning and final solidification period of concrete, such as adding 0.15% sodium gluconate, can extend the initial solidification time of concrete more than 10 times, that is, to extend the plastic time of concrete from several hours to several days without affecting its fastness. Plasticity and delaying the beginning of solidification are very important problems in concrete operation. For example, in high temperature season construction and large-scale engineering operation, delaying the beginning of solidification is a difficult problem. Sodium gluconate can solve this problem satisfactorily. It is difficult to bond oil wells at other high temperatures. The concrete with sodium gluconate can be plastic in a few hours at 170 C, so it can solve the above problems satisfactorily. Sodium gluconate, as a cement admixture, has been widely used in important construction projects abroad, such as many bridges in the Middle East. However, the use of sodium cellulose sulfonate has not been promoted in China. It is said that sodium cellulose sulfonate is extracted from paper-making wastewater, and its effect is not comparable with sodium gluconate.
In addition, it can also be used in electroplating and film making industry.
Sodium gluconate, as an excellent corrosion and scale inhibitor of polyhydroxycarboxylic acid type, will be developed into a large industry if it can make technical efforts due to its many specific properties mentioned above.
處理及除磷的物品。可以在對城市水源水混凝除濁處理同時，到達深度除磷意圖。
從而將處理后飲用水中的磷含量降至界限值以下，不需要改動原水處理流程，不需要增設大型水處理構筑物，簡便易行，經濟實用，可獲得顯著的社會和經濟效益。
河道治理用的除磷劑運用方法量投加不會造成不良影響的多年來聚合氯化鋁已發展成為技術成熟、市場銷量大的絮凝劑，并有逐步取代傳統絮凝劑的趨勢。西歐各國于1976年開始生產聚合氯化鋁，用作工業污水處理絮凝劑;美國、加拿大已于1983年批準將其用于城市給水和工業污水處理。 聚合氯化鋁是水處理混凝劑的常用藥劑，水處理效果顯著，在飲用水、工業污水凈化中有著至關重要的作用。我們常用到的聚合氯化鋁含量有：26%、28%、30%。聚合氯化鋁含量的不同，用途也不同，相對應的聚合氯化鋁價格也不同
水污染的危害顯而易見聚合氯化鋁合理攻堅管理水污染.
4個鄉鎮進行調查,每天的排放量達365.3億噸.其間工業廢水達成協議5.5億噸. 這些廢水絕大部分未經處理就直接排放, 污染了江河湖海. 水污染的危害是不是顯而易見的.水體污染,水質惡化對人體健康和人類日子,出產都帶來了嚴重的危害. Over the years, polyaluminium chloride has developed into a flocculant with mature technology and large market sales, and has gradually replaced the traditional flocculant. Western European countries began to produce polyaluminium chloride as flocculant for industrial sewage treatment in 1976, and the United States and Canada approved its use in urban water supply and industrial sewage treatment in 1983. Polyaluminium chloride (PAC) is a commonly used coagulant in water treatment. Its water treatment effect is remarkable, and it plays an important role in drinking water and industrial sewage purification. The content of polyaluminium chloride is 26%, 28% and 30%. The content of polyaluminium chloride is different, the use is different, and the corresponding price of polyaluminium chloride is also different.
It is obvious that polyaluminium chloride (PAC) can manage water pollution reasonably.
The state has investigated 854 townships and villages, with a daily discharge of 36.53 billion tons. In the meantime, an agreement has been reached on 550 million tons of industrial wastewater. Most of these wastewater is discharged directly without treatment and pollutes rivers, lakes and seas. Is the harm of water pollution obvious? Water pollution and deterioration of water quality have brought serious harm to human health and human life and production?
When green and turbulent forests are replaced by endless desert and yellow dust, white clouds floating carelessly in the blue sky are replaced by rolling black smoke, and the ozone layer that shelters the earth from wind and rain is damaged by relentless Freon, I can clearly hear the cries of forests, the sorrow of white clouds and the sigh of the ozone layer.
The demand of polyaluminium chloride flocculants at home and abroad is increasing rapidly. Especially in water treatment, the traditional flocculants have been gradually replaced by polyaluminium chloride flocculants and become mainstream flocculants. A large number of application practices have proved that the use of polychlorination rate instead of traditional iron and aluminium salt coagulants can significantly improve the purification efficiency of water plants, reduce the cost of treatment, and improve the quality of effluent. Polyaluminium chloride is used as purifier for daily drinking water and industrial sewage (such as oily sewage, printing and dyeing sewage, paper-making sewage, etc.). In addition, it is also widely used in fine casting, paper making and leather making. The effect of high turbidity water is particularly obvious; without alkaline additives or other coagulant aids, it is suitable for wide water quality, fast and large alum composition, high quality, easy sedimentation, high safety of clean water, low corrosiveness and low labor intensity of workers.
It produces high-efficiency polyaluminium chloride, high-efficiency aluminium ferric chloride, high-efficiency polyferric sulfate, high-efficiency basic aluminium chloride, polyacrylamide (yin, yang, non-ionic), activated carbon and various filter materials. The products are widely used in domestic water companies, mines, paper-making, printing and dyeing, steel mills, distilleries and other enterprises, and solve the problems of water pollution and secondary treatment and reuse in many enterprises.
Polyaluminium chloride road nature is around us, green is around us, environmental protection is in our hearts, brains, hands, actions. We can't say what we can do to protect the environment, but at least you know it initially, you feel our nature initially, just for the idea of us together. Sowing green is the science in bathroom that seeds waste surplus and environmental problems from drinking pure water to recycling of waste, recycling of waste and comprehensive utilization of resources. Every effort should be made to manage the environment and all the people will work together to overcome the difficulties.
當一片片綠波洶涌的森林被無垠的荒漠黃塵所替代，當無憂地在湛藍的天空飄揚的白云被漫天滾滾黑煙所替代，當為地球遮風擋雨的臭氧層被無情的氟里昂所損壞，我清楚聽見了森林的哭泣，白云的哀痛，臭氧層的嘆氣。
聚合氯化鋁絮凝劑在國內外的需求量日益激增，特別在給水處理中劑已逐步替代傳統的凝聚劑而成為干流絮凝。大量的應用實踐證明，使用聚合氯化率替代傳統的鐵、鋁鹽混凝劑，可明顯進步水廠的凈化效能、降低處理本錢、改進出水水質。聚合氯化鋁作為日子飲用水和工業污水(如含油污水、印染、造紙污水、等處理的凈化品。以及高霉性重金和含氟污水的處理等;此外，在精細鑄造、造紙、制革等方面亦有廣泛的用處。對高濁度水的作用特別明顯;可不加堿性助劑或其它助凝劑，適宜水質規模寬、礬花構成快而大、質密、易沉降，清水安全性高;腐蝕性小，工人勞動強度低。
出產高效聚合氯化鋁，高效氯化鋁鐵，高效聚合硫酸鐵，高效堿式氯化鋁，聚丙烯酰胺（陰，陽，非離子），活性炭及各種濾料等產品，產品廣泛用于國內自來水公司，礦山，造紙，印染，鋼廠，酒廠等企業，解決了眾多企業水污染和二次處理再利用的難題。
聚合氯化鋁道大自然就在我們周圍，綠色就在我們身邊，環保就在我們的心中，腦中，手中，舉動中。我們不能說我們能為環保做什么，但最起碼你初步在知道它，初步在感觸我們的大自然，只為著我們一起的理念。播種綠色就是播種希望 廢物過剩與環境問題 從喝純水想起 廢物的收回及資源化綜合利用廢物的收回及資源化綜合利用浴室中的科學。想方設法管理環境，眾志成城合力攻堅。
，畢竟鐵也是微生物生長所需要的微量元素。但是如果投加量過大，則會使污泥活性收到影響，還有疑問可以到環保.通交流。
生化末端 沒有影響，何況少量的鐵鹽能夠對Phosphorus removal agent for road treatment is a kind of material for coagulation and turbidity removal of urban water source and phosphorus removal. It can reach the intent of deep dephosphorization at the same time of coagulation and turbidity removal of urban water source.
Thus, the phosphorus content in treated drinking water can be reduced to below the threshold value, without changing the original water treatment process, without adding large water treatment structures, which is simple, economical and practical, and can achieve remarkable social and economic benefits.
The amount of phosphorus removal agent used in river regulation will not cause adverse effects. After all, iron is also a trace element needed for microbial growth. However, if the dosage is too large, the sludge activity will be affected. There are still doubts about environmental protection and communication.
There is no effect on the biochemical end, let alone a small amount of iron salts.
懸浮物上漂
關于污水處理使用聚合硫酸鐵上水層出現漂浮物的原因以及解決方法
污水處理1. Improper operation, some non-professional personnel in the experiment used improper techniques, adding polyaluminium chloride, stirring too fast or too slow can not, the first experiment, there must be professional water treatment assistant, this is a very important point.
2. The amount of polyferric sulfate added is not well controlled (too much or too little dosage). In this case, suspended solids are most likely to float.
Before use, the product was put into the alum bath at a certain concentration (10-30%) and stirred with tap water to make it fully hydrolyzed. The product was put into a red-brown liquid and diluted with water until the required concentration was added and coagulated. Waterworks can also be added 2-5% directly, and industrial wastewater treatment can be added 5-10%. B. The determination of dosage depends on the proper amount of alum formed by production debugging or beaker experiment according to the nature of raw water. The other dosage used in water plant can be used as reference. Under the same conditions, the dosage of this product is approximately equal to that of solid polyaluminium chloride, which is 1/3-1/4 of that of solid aluminium sulfate. If the original liquid product is used, it can be calculated according to the concentration of the corresponding agent. It depends roughly on the weight ratio of 1:3.

They are all professional.
Reasons and Solutions for Floating Matter in the Upper Water Layer of Polyferric Sulfate Used in Sewage Treatment
Polyferric sulfate
5. The last point to consider is whether the quality of the polyferric sulfate you use meets the national standards, and whether the various indicators of the polyferric sulfate meet the national standards.
At present, the quality of polyferric sulfate is uneven in the market. Compared with the better quality of Polyferric sulfate, the probability of suspended solids will be very low. The better polyferric sulfate has almost no water insoluble solids, so the quality of products is also very important. Microbial activity has a promotive effect, that is, effluent color has an impact.
Adding chemical Dephosphorizer to the back of biochemical pond can completely avoid the reaction between various substances in water and dephosphorizer, consume the amount of reagent, and will not reduce the concentration of organic carbon in the influent of biochemical pond, affecting the effect of nitrogen and phosphorus removal by microorganisms. At the same time, it can avoid excessive dosage of phosphorus removal agents, and also make the residual agents into the biochemical system, which will affect the growth of microorganisms.
Adding phosphorus removal flocculant to the outlet of aerobic tank and phosphorus removal agent in front of secondary sedimentation tank can greatly reduce the use of phosphorus removal agent. This is because most phosphorus in wastewater has been removed in the process of biochemical treatment, and phosphorus migration and organic phosphorus are converted into positive phosphorus which can be treated by coagulation, which greatly improves the effect of phosphorus removal and improves the efficiency of phosphorus removal. Reduce the dosage of phosphorus removal agent, reduce sludge production, reduce phosphorus content in sludge. Therefore, chemical phosphorus removal agents are generally added to the biochemical process, before the secondary sedimentation tank, to save the cost of phosphorus removal from wastewater and improve the rate of reaching the standard. ?

5、用于廢物填埋廠廢物滲濾液處理。After fully mixing and homogenizing AlCl3 solution, NaOH solution was added with a molar ratio of 3:2:14; the product was filtered after mixing and standing, and washed repeatedly with water until the effluent was neutral; the granular adsorbent was dried at 100-110 (?) C and made into uniform size. The adsorbent is used to remove phosphorus by adsorption in conventional water treatment process. The adsorbent consists of 2-4 series operation phosphorus removal adsorbents. The structure of the adsorbent is the same as that of the filter. The particle size of the adsorbent is 0.5mm-0.8mm, the thickness of the adsorbent layer is 1.0-1.5m, and the hydraulic force of the adsorbent is negative. Load 5 m/h-8 m/h, empty bed touch time 30-40 min. The adsorbent has wide application scale for phosphorus removal, excellent pollution removal efficiency, simple regeneration, low material price and easy safety.
