摘　　要：以二氧化氯处理生活污水,研究了二氧化氯质量浓度和反应时间对污水中COD去除率、总细菌去除率、大肠杆菌去除率的影响,得出了各因素对分析项目的变化趋势。结果显示,二氧化氯质量浓度2.4 mg/L,COD的去除率达到62.7%;二氧化氯质量浓度3.6 mg/L,总细菌丧除率达到99.7%,大肠杆菌的去除率达到99.1%。反应时间30 min,COD去除率达到65.9%,总细菌的去除率达到99.9%,大肠杆菌的去除率达到99.3%。The chlorine dioxide is used to dispose the snitary waste.The effect of the concentration of chloride dioxide and the reaction time to the romove ratio of COD,total bacterium and colibacillus of sanitary water was investigated in this article.The results showed that when the amount of chlorine dioxide is 2.4 mg/L,the removing ratio of COD is 62.7%;when the amount of chlorine dioxide is 3.6 mg/L,the removing ratio of total bacterium is 99.7%,the removing ratio of colibacillus can reach 99.1%;when reaction time is 30 minutes,the removing ratio of COD,the total bacterium and the colibacillus are 64.9%,99.9% and 99.1% respectively.
