摘　　要：研究了以聚合硫酸铁(PFS)为主凝剂、两性田菁胶(ASG)为助凝利处理高浓度印染废水的各种影响因素。实验结果表明：PFS和ASG分别以2000mg／L和100mg／L的复配浓度、pH值接近中性时混凝效果为最佳，COD_(Cr)去除率达到80％，色度与浊度去除率均达99％以上。Wastewater from printing and dyeing was treated with primary flocculant PFS and coagulant aid ASG. The results showed:when c (PFS)=2000mg/L;c (ASG)=100mg/L and pH=7, the flocculantion effect was best. The reduction percentage of CODCr reached to 80%.The chrominance and turbidity removal rate were over 99%.
