摘　　要：采用磁絮凝技术处理北京市通惠河河水,考察了磁絮凝效果及其影响因素。结果表明:磁絮凝处理效果要好于传统混凝处理效果,对该河水中COD、浊度、TP和氨氮的去除率分别可达到60.00%、73.24%、87.80%和30.10%,出水水质满足《地表水环境质量标准》(GB 3838—2002)的Ⅳ类标准。采用该技术不仅能提高絮凝效果、缩短絮凝与沉降时间、减小絮体体积,且更易于实现固液分离。The polluted Toaghui River water in Beijing was treated by magnetic floceulation tech- nology. The treatment efficiency and influence factors were investigated. The results indicate that the effect of magnetic flocculation technology is better than that of conventional coagulation process, the re- moval rates of COD, turbidity, TP and ammonia nitrogen are 60.00%, 73.24%, 87.80% and 30.10% , and the effluent quality meets IV criteria specified in the Environmental Quality Standards for Surface Water （GB 3838 -2002 ）. The magnetic flocculation technology can raise the flocculation efficiency, shorten the period of coagulation and sedimentation, reduce the floc volume, and improve the solid-liquid separation.
