摘　　要：通过常规给水处理工艺预臭氧化和预氯化对比试验,研究了预臭氧化工艺对水中浊度、氮氮和CODMn的去除效果,对三卤甲烷生成的影响,及其致突变活性的变化。结果表明预臭氧化工艺沉淀池和滤池出水浊度均低于预氯化工艺,其对有机物的去除效果明显优于预氯化工艺,对CODMn的总去除率达53.4%,并能有效去除原水中大量的三卤甲烷前体物,而在致突变活性方面预臭氧化工艺滤后水更安全可靠。同时试验得到在原水CODMn为5-6 mg/L条件下臭氧最佳投加量为1-1.2 mg/L。The effects of pre-ozonization and pre-chlorination before conventional water purification were compared by examination of turbidity, ammonia nitrogen, CODMn and THMs in the output water with ozonization or chlorination pretreatment. For the safety of the output water also Ames test was done. The results showed that for both the turbidity and organic removals the pre-ozonization seems better than the pre-chlorination evidently. Overall removal of 53.4% for CODMn was obtained and huge of THMFP in the raw water was removed. Also the mutagenic safety of pre-ozonization water is better. The best O3 dosage of 1 to 1.2 mg/L has been deduced at condition of inlet CODMn = 5 to 6 mg/L.
