污泥脫水沉淀劑的使用技巧 聚丙烯酰胺陰離子和陽離子的選配方法

2020 is destined to be a tough year for donai, with tears, feelings and short joy after victory. In the face of the global explosive epidemic, how will our water purification industry develop Henan anjiajing environmental protection technology, devoted to the production of polyacrylamide poly aluminum chloride poly ferric sulfate? Over 20 years, we have experienced many experiences in Central China, neighboring Hubei Province The epidemic situation is very serious. In March, under the leadership of the government and the command of the party, we basically defeated the epidemic situation. The enterprises returned to work and started to produce polyaluminium chloride polyacrylamide, which basically entered the normal stage. Because our workers are basically the raw materials required by the mature production technology of local employees, and also the polyacrylamide that can be purchased in the province As a necessary medicine for sewage treatment, polyaluminium chloride is indispensable in every industry of every enterprise, but the impact is not on our internal prod
uction, but on the external production of many small enterprises, which can not use the most sand washing food sewage plants, sewage plants, which can not stop, the most impact is that small manufacturers, we have a strong production force to settle down With the support of capital support and old customers, the daily shipment volume is more than 100 tons, and the price is also provided to customers with the support of the government's tax-free and rent-free stimulus economy to help small and medium-sized enterprises through difficulties, with high quality and low price and stable market sentiment
Henan anjiajing environmental protection polyacrylamide polyaluminium chloride polyferric sulfate selection we choose one service, one integrity, one moving, one stable and looking forward to your call manager of anjiajing environmental protection Cao 15838356978
標，陰離子分子量大多都在800-2000萬之間。 跟著水解度的添加，羧基陰離子添加，分子鏈不斷伸展，然后有使絮凝作用逐漸增強的作用；一起，聚丙烯酰胺分子的負電性亦逐漸增強，又阻礙了其與負電性的泥沙雜質(zhì)相吸附，并且在吸附架橋中起 首要作用的活性基團-酰胺基也不斷減少，然后跟著水解度的添加，又存在使絮凝作用逐漸變差的要素。 陰離子聚丙烯酰胺作為綜合成果：水解比過大，加堿費用較高，水解比過小，又會使反應(yīng)不足，陰離子型聚丙烯酰胺的混凝或助凝作用較差。 所以陰離子聚丙烯酰胺不一定水解度越高越好，什么都會有個限度，適宜的才是zui優(yōu)的河南安家凈環(huán)保是一家專業(yè)出產(chǎn)各種水處理藥劑，致力于綠色環(huán)保可再生資源的繼續(xù)使用，很多投入了科 研資金，首要產(chǎn)品有聚丙烯酰胺絮凝系列，聚合氯化鋁系列，聚合硫酸鐵系列，堿式氯化鋁等均受到全國客戶的一致好評，咱們將一如即往的出產(chǎn)出品質(zhì)優(yōu)質(zhì)的產(chǎn)品來報答客戶對咱們一向的支持聚丙烯酰胺生產(chǎn)及市場現(xiàn)狀分析，可得以下幾點認識：
多人在使用前，都知道需要經(jīng)過進行小試后確定聚合氯化鋁的使用方案后在進行大量的投加使用，其中小試需要得到的有聚合氯化鋁的類型、含量、溶解濃度、使用方法等。那么如何進行聚合氯化鋁的小試呢？河南濾源環(huán)保科技有限公司為您介紹一下。
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(xiàn)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(chǎn)廠，其中有5個萬噸級PAM大廠。這典 廠家占全國年產(chǎn)量的56%，生產(chǎn)的集中度正在提高。PAM全行業(yè)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(chǎn)成本、環(huán)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，有取代高分子聚丙烯酰胺的趨勢，而我國能夠生產(chǎn)抗鹽聚合物的企業(yè)只有三四家，總生產(chǎn)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(yīng)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 polyacrylam
ide 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.
