非離子聚丙烯酰胺
??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(shí)刻就有限了，一般說，溶液濃度為0.1%的時(shí)候，非離子與陰離子聚丙烯酰胺溶液不會(huì)超過一周的時(shí)刻，陽(yáng)離子聚丙烯酰胺溶液則不會(huì)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(shí)刻越長(zhǎng)，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(yáng)離子聚丙烯酰胺溶液PH值小于5.5的時(shí)后比較穩(wěn)定，假如大于6.0的話，就會(huì)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(gè)月。
生化末端 沒有影響，何況少量的鐵鹽能夠?qū)hosphorus 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 structur
es, 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.

關(guān)于污水處理使用聚合硫酸鐵上水層出現(xiàn)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.

The suitable range of PH value is 4-11, and the optimum range of PH value is 6-9. After purification, the change range of PH value and total alkalinity of raw water is small.
4, the type of water purification products is not correct. According to the characteristics of sewage, choose suitable water purifying agent suitable for its own sewage characteristics, such as polyaluminum chloride, polyaluminum chloride, polyaluminum ferric chloride, aluminum chloride, spray polyaluminum chloride, white polyaluminium chloride, etc., and listen to the advice of professional water treatment division, and give their advice. They are all professional.

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. ?
When in use, the product can be directly added or participated in the dissolving tank, the concentration of which is 10-20%, mixed and pumped into the reaction tank. The product is suitable for a wide range of pH values, especially in acidic conditions. Its application amount is about 100-1000 ppm (i.e. 0.1-1 kg/ton wastewater). According to the different content of phosphate in wastewater, its dosage is different. The detailed dosage is generally determined by experiments.
During the experiment, a certain amount of raw water was taken and the product (such as 500 ppm) was added. The pH value of the wastewater was adjusted to 7-8. www.hnldscl.com participated in the flocculation and deposition of a few PAM. The supernatant was filtered to determine the phosphorus content.

低溫絮凝效果很差。但聚合氯化鋁在處理低溫水方面仍有較好的效果。聚合氯化鋁的絮凝效果受常溫或低溫水的影響較小。除此之外，現(xiàn)有的凈水產(chǎn)品大多需要在低濁度和低污染水的處理中加入大量助劑，以便在后續(xù)的處理中取得更好的效果，但不需要聚合氯化鋁。
