According to the data, the polyacrylamide used in the steel industry in China at this stage is mainly anionic polyacrylamide, which is suitable for steel plant sewage with positive ionic surface charge. Polyacrylamides used in steel plants are mainly used for the settlement and separation of ore slurry suspensions. The PH value of the treated sewage is mostly neutral or alkaline suspensions containing more inorganic substances.

　　The test shows that the anionic polyacrylamide (dosage 0.3mg/l) is selected for coagulation stacking is able to make the settling efficiency reach more than 90%, when the cycle time is long and the cycle rate is high, polyacrylamide and a small amount of inorganic coagulant such as ferric chloride or polymeric aluminum chloride are used together, which can effectively go to remove fine particles. In order to speed up the settling of suspended particles and adjust the PH value of the sewage, polymer coagulant and PH adjuster such as sulfuric acid or lye are added in the distribution tank for the treatment of converter flue gas COD method de-dusting sewage. The average SS before water quality treatment is 5000mg/L, after treatment is 200mg/L, when adding PAM is 50mg/L, the dosage is 1-5mg/L. General steel company converter de-dusting circulating water management, stacking, sludge thickening, dewatering and other technologies, sludge dewatering with PAM, consumption is 500g per ton of dry mud.

　　In steel plants, polyacrylamide is mainly used in anionic polyacrylamide, the specific choice of which agent, according to the site sewage to do a small test selection experiments to determine. The treatment effect of polyacrylamide is mainly depends on the charge in the sewage and polyacrylamide model match the problem, lies in the selection of accurate or not. The wider the range, the more models, the more you can choose the right model. Guangdong Shouxin Environmental Protection Materials Technology Co., Ltd. is a global polyacrylamide brand with stable quality , after more than ten years of development Shouxin brand polyacrylamide has two obvious advantages, and is favored by customers in steel plants:

　　1. More models of polyacrylamide: there are 107 different models of polyacrylamide, which can provide customers with accurate selection experiments and select more cost-effective polyacrylamide models for customers.

　　2. Stability of polyacrylamide products: As Shouxin is a global polyacrylamide brand with stable quality, we can do strict double supervision and testing when inbound and outbound through professional technical engineers and advanced testing equipment, less concern about production cost, and will strictly control the quality and qualified products before entering the warehouse. To ensure the stability of the product.
