摘　　要：混凝澄清法通过在废水中加入絮凝剂,使废水中的胶体凝聚并沉降,在印染废水中可以较好的去除原水的浊度和色度。本研究采用自行制备聚硅酸金属盐类絮凝剂聚硅硫酸铁(PFSS),探索影响纺织印染生化出水的混凝工艺的参数因素。结果表明,采用聚硅酸硫酸铁絮凝剂絮凝,最佳条件下,废水COD去除率最高达到75%,色度去除率达到80%。The coagulation clarification method is able to agglomerate the colloid in the waste water and make them subside by adding flocculants in wastewater. It is better to eliminate the turbidity and the chroma of the raw water. This research used self - prepared polysilicate metal salt coagulant poly - ferric silicate sulfate （PFSS） to explore the influencial factors of the coagulation process of the textile printing and dyeing biochemical water. The results show that the COD removal rate of the wastewater reached 75% and the chroma removal rate reached 80% by using poly - ferric silicate sulfate flocculant under the optimal conditions.
