Study on coagulation treatment of tannery wastewater
皮革废水混凝处理实验研究

Tannery wastewater was treated by chemical coagulation.The treatment efficiencies of three kinds of inorganic coagulants and one kind of organic coagulant were compared and studied.The effects of pH value and coagulant dosage on the removal efficiency of suspended solids(SS),COD,chromium and colour in the wastewater were investigated.The results show that the coagulation efficiency of the wastewater is good under basic conditions,but it is not obvious under acid and neutral condition.The three kinds of coag...
