混凝沉淀去除丙烯酸丁酯废水浊度物质
Removal of turbidity from butyl-acrylate wastewater by coagulation-sedimentation
摘要
Abstract
Turbidity removal of butyl acrylate wastewater by coagulation sedimentation was investigated. Six coagulants were compared for their turbidity removal efficiency. Poly aluminum chloride( PAC) was the best coagulant for the wastewater treatment. Cationic polyacrylamide ( CPAM ) was selected as coagulation aids. Optimized coagulation conditions are PAC of 150 mg/L, CPAM of 20 mg/L, pH of 4 ～5, water temperature of 20 ～ 40T℃, fast mixing speed of 200 -400 r/min, 1～3 min, slow stirring of 50～80 r/min, 5～15 min. Under the above conditions, the turbidity of wastewater would decrease from 3 000 NTU to about 1 NTU, and large amounts of colloids were also removed during the coagulation process.关键词
