摘　　要：通过用一种天然有机高分子化合物制备的复合絮凝剂在活性染料染色废水处理中应用,并与无机高分子混凝剂聚合铝铁、聚合氯化铝进行脱色效果的比较,发现其在酸性和近中性条件下对酸性、活性、分散、还原等染料均有较好的混凝脱色效果,同时通过对回流污泥工艺的改进可减少沉降时间。A complex flocculant prepared by a natural organic polymer compound was used to treat reactive dyeing wastewater,whose effect was compared with that of polyaluminium-iron and polymer aluminium chlorid.It was found that this flocculant had good decolourization effectiveness on acidic,reactive,dispersive and reductive dyes.Meanwhile reduction of settlement time by modifying process of return sludge was also studied.
