摘　　要：凉果废水引起的污染已经成为严峻的问题。研究了潮安县康辉集团凉果厂综合排放废水的性质,采用混凝沉降工艺处理该废水。为了强化凉果废水的混凝预处理效果,试验研究了混凝剂聚合氯化铝(PAC)的最佳投加量。实验表明:采用PAC工艺处理凉果废水的效果较好,投药后经混凝沉降,废水的COD去除率可以达到46.73%,出水COD可以降至在1 198 mg/L左右。The pollution caused by preserved wastewater has become a serious problem.In this paper,properties of waste water from Chaoan Comfort group preserved plant were studied,and the wastewater was treated by coagulation-settlement.In order to reach the best treatment result,optimal dosage of the coagulant PAC was investigated by tests.The experiments show： treatment effect of PAC process for preserved wastewater is better,removal rate of COD can reach 46.73%,and effluent COD can be reduced to about 1 198 mg / L.
