用滴管將聚合氯化鋁的水溶液慢慢添加到污水中，并使用玻璃棒進行攪拌，觀察污水的絮凝效果，如果出現礬花就表示聚合氯化鋁的絮凝效果較好，然后將不同的量的聚合氯化鋁水溶液添加到污水的樣品中，攪拌靜置一段時間后觀察看哪個污水樣品更加干凈清澈。在使用聚合氯化鋁的過程中，有時候需要添加一些其他的助凝劑如聚丙烯酰胺等，這樣會加快污水的絮凝和沉淀達到更加好的處理效果。ties. The flocculation is deteriorated gradually with the addition of hydrolysis degree. Anionic polyacrylamide as a comprehensive result: the hydrolysis ratio is too large, the cost of adding alkali is higher, the hydrolysis ratio is too small, and the reaction will be insufficient, the coagulation or coagulation of anionic polyacrylamide is poor. Therefore, anionic polyacrylamide is not necessarily hydrolyzed higher, the better, everything will have a limit, the appropriate is Zui excellent Henan Anjiajing Environmental Protection is a professional production of various water treatment agents, committed to the continued use of green and environmentally friendly renewable resources, a lot of investment in scientific research funds, the primary product is polyacrylamide flocs. Coagulation series, polyaluminium chloride series, polyferric sulfate series, alkaline aluminium chloride series and so on are all praised by the national customers. We will continue to produce high-quality products to repay customers for our support of the production and market analysis of polyacrylamide, we can get the following understandings:
1、我國已有10個5000t/a以上的PAM生產廠，其中有5個萬噸級PAM大廠。這典 廠家占全國年產量的56%，生產的集中度正在提高。PAM全行業的總銷售額為62億元。
4、由于一些油田淡水資源的缺乏及降低生產成本、環保等方面的要求，三次采油多采用污水配制聚合物，對耐溫抗鹽聚合物的需求越來越多，有代高分子聚丙烯酰胺的趨勢，而我國能夠生產抗鹽聚合物的企業只有三四家，總生產能力在6×104t左右，遠遠不能滿足三次采油的需求，因此，抗鹽聚丙烯酰胺具有廣闊的應用前景。
There are 10 PAM factories with a capacity of more than 5000t/a in China, of which there are 5 large PAM factories with a capacity of 10,000 tons. This manufacturer accounts for 56% of the country's annual output, and the concentration of production is increasing. The total sales volume of PAM industry is 6.2 billion yuan.
2. The main uses of PAM are oil field, water treatment and papermaking, and there is still room for increasing the amount of PAM. The second largest market, water treatment, has accounted for one fourth of the total PAM market and will grow faster than the oilfield market. At present, the paper-making market is relatively concentrated and occupied by four or five PAM factories, some of which have strong specificity. The proportion of cationic polyacrylamide is only 13%. From the future development of water treatment market, the development of cationic polyacrylamide will have a faster growth rate.
3. At present, PAM products occupy an important position in China's energy strategy and water-saving strategy, and are indispensable products. It will play a more active role in the energy crisis in China and the world as well as in the next more serious water resources crisis.
4. Because of the shortage of freshwater resources in some oilfields and the requirement of reducing production cost and environmental protection, sewage is mostly used to prepare polymers for tertiary oil recovery. There is an increasing demand for temperature-resistant and salt-resistant polymers, which tends to replace polymer polyacrylamide in an all-round way. However, only three or four enterprises in China can produce salt-resistant polymers. The total production capacity of salt-resistant polyacrylamide is about 6 *104t, which can not meet the demand of tertiary oil recovery. Therefore, salt-resistant polyacrylamide has broad application prospects.
In addition, the demand for polyacrylamide products will increase considerably in recent years due to the attention paid by our government and relevant enterprises to sewage treatment. Most domestic enterprises plan to build polyacrylamide projects mainly for urban sewage treatment. According to experts'prediction, the annual demand of municipal wastewater treatment in Shanghai alone will reach 1 x104t. It can be expected that the application potential of polyacrylamide products in wastewater treatment will be tremendous.
It can be seen that salt-resistant polyacrylamide products have broad application prospects in tertiary oil recovery and sewage treatment.
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.

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. ?
