Study on Treatment of Inorganic Polymer Coagulant in Initial Rainwater in Smelter

The selection principle of coagulant was introduced, and the removal effect of several commonly used water treatment inorganic polymer flocculants on heavy metal ions in wastewater was studied. By comparing the effluent after flocculation and settlement of polyferric sulfate and PAM, it was found that polyferric sulfate helped improve the effluent COD index, while optimizing the order of addition could reduce the alkali unit consumption.
