Based on the natural characteristics of Dianchi Lake water, the impact of four flocculants, including A1C13, FeCl3, FeSO4 and polyalu-minum chloride,on the COD and total phosphorus in Dianchi Lake water was discussed,and the removal rate of COD and total phosphorus was analyzed at different closes of flocculants. The research results provided certain theoretical and practical value to the removal of pollutants in lake water.%以滇池水体为研究对象,在研究了天然状况下水体水质的基本特性后,以FeCl3,AlCl3,FeSO4和聚合氯化铝为絮凝剂,分别探讨了4种絮凝剂对滇池水体COD和总磷的影响,并分析了不同剂量絮凝剂的加入对滇池水体COD和总磷去除的影响规律.该研究成果对滇池等湖泊水体的污染物去除有一定的理论和实际应用价值.
