摘　　要：针对目前工业废水中重金属离子去除这一难题,进行了在重金属工业废水处理过程中投加新型混凝剂的试验。试验采用PAFSS与"YX-2型高效多功能混凝剂"相结合的投加方式,能有效地将废水中的锌残余含量降低至1.5 mg/L以下,镉降至0.05 mg/L以下。As for difficult problem of heavy metal ion removing in existing industrial wastewater, many experiments of adding new type coagulants are carried out in heavy metal industrial wastewater treatment. The experiments adopt adding method of combining PAFSS with YX-2 high-efficiency multi-functional coagulants, by which zinc residual content in wastewater can be effectively reduced below 1 .Stag/L, cadmium content can be reduced below 0.05 mg/L.
