摘　　要：以剑水蚤死体溶出物为研究对象,通过二氧化氯预氧化与氯联合消毒,改变二氧化氯的投加量,预氧化时间,pH和温度等条件对消毒副产物的形成进行研究,结果表明,随着二氧化氯投加量增加,1,1-DCP,TCM,1,1,1-TCP和CH浓度均呈下降趋势。1,1-DCP和TCM的浓度随着二氧化氯预氧化的时间的增加而降低,1,1,1-TCP随着预氧化时间增加而升高,TCM没有明显的变化趋势。CH,1,1-DCP,1,1,1-TCP,的浓度随着pH增加而降低,TCM的浓度随着pH的增加而升高。当改变温度时,1,1-DCP,1,1,1-TCP随着温度升高而降低,TCM随着温度升高而增加,CH在10~20℃升高之后降低。Taking dead body dissolved matter of Cyclops as the research object,The formation of disinfection by-products was investigated under the conditions of changing dosage of chlorine dioxide,pre oxidation time,pH and temperature during chlorine dioxide pre oxidation combined with chlorine disinfection. The results showed that the formation of 1,1-DCP,TCM,1,1,1-TCP and CH decreased with increasing chlorine dioxide dosage. The formation of 1,1-DCP and TCM decreased with increasing pre oxidation time,and the 1,1,1-TCP increased with the increasing pre oxidation time. The formation of CH,1,1-DCP,and 1,1,1-TCP decreased with increasing pH,and the formation of TCM increased with increasing pH. When the temperature changed,1,1-DCP,1,1,1-TCP decreased with increasing temperature,TCM increased with the increasing temperature,CH first increased at 10~20℃ and then decreased with increasing temperature.
