| 摘 要： | 研究了以聚合硫酸铁(PFS)为主凝剂、高取代度季铵型阳离子化玉米淀粉(HQCC)为助凝剂处理城市生活废水的各种影响因素．实验结果表明：PFS和HQCCS分别以200mg／L和10mg／L的复配浓度、pH值接近中性时混凝效果为最佳，CODCr去除率达到80％，色度与浊度去除率均达99％以上．

| Abstract: | Domestic wastewater was treated using primary flocculant PFS and coagulant aid HQCCS.The results showed:when c(PFS)=200mg/L;c(HQCCS)=10mg/L and pH=7,the flocculantion effect is best.The reduction percentage of COD_(Cr) reaches 80%.The chrominance and turbidity removal rate of it are over 99%. |
