摘　　要：实验采用微波—混凝法处理滇池高藻原水,考察了混凝剂聚合氯化铝(PAC)投加量、进水pH值、微波功率及辐照时间对除藻去浊效果的影响,并与单一混凝的处理效果进行了对比。结果表明:在PAC投加量为80mg/L、进水pH值为8～9、微波功率为600W、辐照时间为1.5min的条件下除藻去浊效果最佳,除藻率达94.4%,剩余浊度可从89NTU降到3NTU左右;微波—混凝法对滇池高藻原水的处理效果明显优于单一混凝,同时可降低混凝剂用量,具有良好的强化混凝效果。Microwave-coagulation process was used for the treatment of high algae water from the Dianchi lake. The efficacy of removing algae and turbidity were investigated with the coagulant dosage of PAC, inflow pH, microwave power and irradiation time, then compared with the single coagulation. The results showed that under the condition of PAC 80mg/L, inflow pH 8 - 9, microwave power 600W, radiation time 1.5min, the efficacy of removing algae and turbidity was the best, the removal rate of algae was 94.4%, the turbidity of effluent could be reduced from 89NTU to about 3 NTU ; its effects were better than the single coagulation, as well as reducing the dosage of coagulant. Microwave -coagulation process could enhance coagulant effects.
