摘　　要：采用了一种磁絮凝-磁盘分离技术处理湖泊富营养化水的工艺方法。试验结果表明,该方法对去除巢湖水体中氮、磷和藻具有良好效果。当复合絮凝剂加入量为250.67mg·L-1,磁粉加入量为50mg·L-1,磁盘转速为1.2r·min-1,水样流速为0.09m·s-1时,巢湖试验水样经过处理,总磷、总氮、COD和浊度的去除率分别可达94.3%、70.4%、92.3%、98.8%,出水水质达到国家一级排放标准。The new technology of magnetic flocculation-magnetic disc separation was applied to treat Chaohu eutrophication of water. The experimental research shows that the technology for removing N,P and algae in the lake is achieved good results, The best conditions was：compound floeeulant dosage of 250.67mg·L^-1, magnetic seeds dosage of 50mg·L^-1, the magnetic disk rotational speed of 1.2r·min^-1, the water flow speed of 0.09m·s^-1. After the treatment of experimental lake water, the removal rates of TN, TP, COD and algae are 94.3%, 70.4%, 92.3% and 98.8%, respectively, which can meet the municipal wastewater discharge standard.
