加速顆粒沉降。 Flocculants are mainly used in the field of water supply and sewage treatment. It is a polymer coagulant added to wastewater. After the polymer coagulant dissolves, the polymer is formed.方法所得出的分類是不一樣的，假如依照離子型可分為陰、非、兩性及陽離子聚丙烯酰胺，假如依照形狀的話，能夠分為膠體、渙散液、乳液和干粉顆粒四種形狀，那么這四種形狀哪一種更適合我們
呢？公司給您一些主張，接下來是我們的經(jīng)歷所得，希望您會感興趣。
??在平常假如我們常常運(yùn)用，能夠選擇干粉顆粒狀聚丙烯酰胺，The classification obtained by the method is different. If the ionic type can be divided into Yin, non, amphoteric and cationic polyacrylamide, if according to the shape, it can be divided into four shapes: colloid, laxity, emulsion and dry powder. Which of these four forms is more suitable for us? The company gives you some suggestions. Next is our experience. I hope you will be interested.
In general, if we often use it, we can choose dry powder granular polyacrylamide. Because of its highest solid content, dry powder polyacrylamide is generally stored in dry and cool places for more than two years, but if mixed with solution, its storage time will be limited. Generally speaking, when the concentration of solution is 0.1%, non-ionic and anionic polyacrylamide will dissolve. The stability of cationic polyacrylamide solution depends on the concentration of the solution. For example, the more concentrated the solution is, the longer the storage time of 3%-5% solution is, but the 3%-5% solution can not be directly used to treat sewage. This solution needs to be diluted before use, and the PH value of cationic polyacrylamide solution is less than 5.5. Stability, if greater than 6.0, will be due to hydrolysis and failure, water medium dispersion polyacrylamide shelf life of six months.
Therefore, polyacrylamide is still a better choice of solids, can be used with the mix, do not cause waste.
Of course, we must pay attention to the conditions and taboos of preserving polyacrylamide. Polyacrylamide is more sensitive to iron ions, calcium ions and magnesium ions than anionic polymers. In particular, iron ions are catalysts for the chemical degradation of all polyacrylamide. Therefore, in the manufacture, handling and storage of polyacrylamide solutions, we must try to avoid iron ions entering and touching the solution. The equipment should be made of plastics, stainless steel, FRP or carbon steel with surface coating resin.由于它的固含量，一般情況下干粉聚丙烯酰胺在干燥、陰涼的當(dāng)?shù)厥羌拇娑暌陨系模偃缗涑扇芤旱脑挘募拇鏁r刻就有限了，一般說，溶液濃度為0.1%的時候，非離子與陰離子聚丙烯酰胺溶液不會超過一周的時刻，陽離子聚丙烯酰胺溶液則不會超過一天，而且溶液的穩(wěn)定性與溶液的濃度有關(guān)，配的濃度越濃，例如3%——5%的溶液寄存時刻越長，但3%——5%的溶液不能直接去處理污水，這種在運(yùn)用前需要稀釋，陽離子聚丙烯酰胺溶液PH值小于5.5的時后比較穩(wěn)定，假如大于6.0的話，就會由于水解的原因而失效，水介質(zhì)渙散型聚丙烯酰胺保質(zhì)期為六個月。
4.當(dāng)原水濁度為100-500mg/L時，用量為5-10mg，即每千噸水5-10kg。使用前，根據(jù)水質(zhì)特點(diǎn)進(jìn)行小試，選擇合適的值，然后施工使用。
一、在低濁度水中，將固體聚合氯化鋁產(chǎn)品按照1：3份額(分量比)加自來水稀釋，并且攪拌至完全溶解
二、在日子、出產(chǎn)用污水中，參照每噸污水先投加30g左右的聚合氯化鋁產(chǎn)品。然后投加稀釋之后的聚丙烯酰胺產(chǎn)品，(假如作用不明顯，請酌情減少或增加產(chǎn)品投加量。)
三、在造紙廠污水處理中，選用低濁度水的投進(jìn)份額配備，如作用不明顯可在酌量增加。
四、原水濁度在100-500mg/L時，投加量為5-10mg即每千噸水投量為5-10kg，根據(jù)水質(zhì)特性進(jìn)行小試，選出合適值，然后投用。The proposal of this cause has attracted wide attention at home and abroad, and has been recognized as one of the most influential and recognized milestones in the field of environment in recent years.
Thereafter, the construction of the concept factory was vigorously promoted. By the end of 2014, the preliminary design and site selection work will be completed, the overall design will be completed in 2016, and the project construction approval and construction design will be completed in 2017. Officials said that the first sewage treatment conceptual plant could be completed in 2019.
Wang Hongchen, deputy dean of the Environmental College of Renmin University of China, told reporters that a year and a half ago, the sewage treatment conceptual plant had gathered a group of powerful basic teams to carry out relevant experiments on the spot, build production and R&D centers, speed up the transformation of science and technology, and carry out extensive industrial cooperation. "One is to build the experience center of new technology, promote the research and development, transformation and promotion of new technology; the other is to build the production-oriented research and development center of municipal sewage treatment, and build a new model of new technology from laboratory to practical application. Thirdly, we should promote the development of wastewater treatment technology from laboratory to engineering, and create a new high ground for China's cooperative industries.
According to the introduction, the concept factory initially established the technical route of sustainable water treatment facing the future, and established the business model and innovation model of "ecological complex" and "production-oriented R&D center" guiding industrial development.
For the basic ideas of the technical route, experts said that the main way is to improve energy recovery by carbon segregation, and to achieve the level of water treatment available. The effluent standard of "concept plant" will be much higher than that of current sewage treatment plants, which is of great significance for improving the quality of water environment and promoting ecological construction. "In the future, the conceptual plant will be expanded to an ecological area, like a demonstration of an urban ecological complex, and ultimately realize that a treatment plant can drive a city's ecosystem." Wang Hongchen said.
"Sewage treatment conceptual plant is an innovative work. It can not simply be regarded as a project, a project, a factory, but a social work to promote the leapfrog development of the industry." Wang Hongchen said so.
The damage of water pollution clearly shows that polyaluminium chloride is a reasonable way to deal with water pollution.
As a new year's first film, the piglet's past New Year is not the same as most movie promotion or promotion films. It's a story of "who is page". It's a story of "who is Paige": Li Yubao, who stays behind, doesn't know what his grandson wants to be "Paige". Finally, a pink Page was welded with a blower and sent to his grandson. Settlement Net Polyaluminium Chloride invites you to watch "What is Page"
What must be done and what must be said in the daytime can not be ignored now." Zhu Ziqing wrote in The Moonlight of Lotus Pond that "a person can think of anything and not think of anything in this vast moonlight, so he feels a quiet person." Last night, this valuable leisure was infected by a short video of "Who is Page?"
Henan Settlement Net Hebei Science and Technology Co., Ltd. year, has gone through 14 years in the beginning, the experience of the storm and pain in the hearts of the people, sweat and tears, success and happiness intertwined. Settlement net do not want to do anything is to do a good job of products, after hard struggle, our plant water treatment pharmaceutical products to reach the national GB15892-2003 specification. And through the ISO 9001:2000 international quality system certification, from all aspects of checks, the performance rate of the contract is 100%, the qualified rate of the products has reached 100%, which has been promulgated by the Municipal Technical Supervision Bureau as a reliable unit of quality and measurement.
According to the dosage of polyaluminium chloride in different water quality, the net settled polyaluminium chloride is introduced.
1. In low turbidity water, the solid polyaluminium chloride product is diluted by adding tap water in proportion of 1:3, and stirred until completely dissolved.
2. In daily and production wastewater, the polyaluminium chloride product should be added about 30g per ton of wastewater. Then add diluted polyacrylamide products. (If the effect is not obvious, please reduce or increase the product dosage as appropriate. )
3. In the sewage treatment of paper mills, the input share of low turbidity water should be selected and equipped. If the effect is not obvious, it can be increased at a reasonable level.
4. When the turbidity of raw water is 100-500 mg/L, the dosage is 5-10 mg, i.e. 5-10 kg per thousand tons of water. It is better to carry out small-scale tests according to the characteristics of water quality before using, select the appropriate value, and then put it into use.

One end of the line pulls out a tiny particle, the other pulls out another tiny particle, and acts as a bridge between two distant particles, which gradually enlarges the particle # and eventually forms a large 聚合氯化鋁的水不溶可以通過溶解聚合氯化鋁來觀察。一般情況下聚合氯化鋁溶解后的水溶液較為渾濁時，就表示聚合氯化鋁中的水不溶物較多，反之溶解后的聚合氯化鋁水溶液越清澈，就表示聚合氯化鋁中的水不溶物含量越低。需要注意的是，聚合氯化鋁在固體狀態(tài)下很難直接分辨聚合氯化鋁中水不溶物的情況。
