摘　　要：考察了几种常用混凝剂对印染废水的处理效果。研究表明，在最佳pH值9～11时，硫酸亚铁具有较好的处理效果；复配试验表明，当硫酸亚铁投加量为400mg／l，熟石灰400mg／1，PAM为2mg／l时，COD去除率76．3％，色度去除率94．5％．处理成本为0．16元／t。The actua wastewater with high effect of several common coagulants for the treatment of compositive dyeing and printing content of color chrominance and COD were studied. The result whowed that the ferrous sulphate had better effect than other coagulants and the best pH value range was 9 - 11 ;the mixture experiment showed that., when ferrous sulphate was 400 mg/l,white lime 400 mg/l,PAM 2 mg/l,the COD and color removal rate reached 76.3% and 94.5% respectively,treatment cost was0.16 yuan per ton.
