高取代度季铵型阳离子化玉米淀粉在处理城市生活废水中的应用
Application of high substitution degree quaternary ammonium cationic corn starch
【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(HQCCS)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 CODCr reaches 80%.The chrominance and turbidity removal rate of it are over 99%.
