Novel Polyacrylamide for Wastewater Treatment in Metallurgical Iron and Steel Industry

As one of the most important pillar industries in our country, the steel industry has made great contributions to the economic construction of our country. At the same time, it is also inevitable that a large amount of waste water and waste water will be polluted, causing great harm to the environment. Using anionic polyacrylamide flocculant APAM to treat the metallurgical steel wastewater, the metal particles in the sewage form a flocculation mass, which achieves the purpose of sewage treatment with high efficiency and good effect.
Ferrous metallurgy wastewater mainly comes from the production process water, equipment cooling water, steel cooling water and site clean water. Iron and steel metallurgy wastewater contains a lot of mercury, lead, arsenic, zinc and other heavy metal ions, as well as BOD, COD, phenol, cyanide, sulfide and so on. Sewage composition is complex, suspended particles and more metal concentration, sewage ions with a positive charge, the sewage PH value for more neutral and alkaline. It must be treated to discharge, otherwise it will cause huge harm to the environment. Anion polyacrylamide flocculant APAM molecular chain containing -CONH2 anionic groups, after flocculation flocculation settling, cooling, circulating water treatment can be recycled.
Anionic polyacrylamide flocculant used in the iron and steel metallurgy industry APAM is mainly used to remove circulating water and impurity ions in the production process, the APAM molecular weight is generally chosen as the best 10 million or more, about 7-15g of anionic polyacrylamide
