Special polyacrylamide achieved domestic production

It is understood that for a long time, domestic polyacrylamide has been generally used in back-end sewage treatment processes with low technical requirements, such as external drainage treatment. Due to the harsh conditions in the front-end process of sewage treatment, the requirements for flocculants are high. Abnormal fluctuations will affect normal production. The water treatment agent market for the flocculant used in the front-end process, that is, special polyacrylamide, has always been occupied by international chemical giants such as Germany and France, and its production technology has also been monopolized.

To this end, Peng Yiyun established a team composed of postdoctoral researchers from the University of Science and Technology Beijing, Tsinghua University, Chinese Academy of Sciences, and Central South University A highly educated R&D team to develop special polyacrylamide production technology. It took the team 20 years to finally break through the foreign technology blockade and master the key technology for the production of special polyacrylamide.

Peng Yiyun said that the special polyacrylamide dry powder product developed by the company has four major advantages: First, the product is water-soluble It has good properties, fast dissolution speed and only takes 5 minutes to dissolve, which can save nearly 70% of the time for sewage pretreatment and save investment in the preparation of flocculants; secondly, the reaction time is short, and the product can be mixed with various types of sewage in just 3 seconds. Solid suspended matter quickly combines, flocculates, settles and stabilizes, while ensuring normal production; third, the amount of input is less, half the amount of imported products, the product is cost-effective, and can reduce the company’s sewage treatment cost per ton by 20%; fourth, it is durable High temperature, strong acid, strong alkali, etc., harsh environments will not affect the product use effect, and can also save large-scale investment in conventional acid-base neutralization workshops.

It is understood that special polyacrylamide is a polymer flocculant. After special modification treatment, it can be widely used in Used for municipal sewage treatment, as well as sewage treatment in petrochemical, mining, coal preparation, metallurgy, papermaking, textile and other industries. At present, Yiqun Environmental Protection has cooperated with many large domestic enterprises such as China Aluminum Group, Henan Nenghua Group, and Hangzhou Jinjiang Group.
