摘要
以壳聚糖絮凝剂作为聚合氯化铝 (PAC)的助凝剂 ,絮凝处理颐和园昆明湖湖水 ,考察了PAC在壳聚糖助凝作用下对浊度和有机物的去除效果 ,以及水中残留铝浓度的变化 .结果表明 ,壳聚糖对PAC的助凝作用显著 ,PAC中加入壳聚糖絮凝剂后 ,浊度和有机物去除率均明显提高 .
Flocculant chitosan was used to enhance the flocculation treatment of the surface water from Kunming lake in Summer palace,Beijing by polymeric aluminum chloride(PAC).The improvement of removal efficiency of turbidity and TOC indicated that chitosan could enhance the flocculation treatment by PAC significantly.In the mean time,flocculant chitosan caused less residual aluminum in the effluent.
