摘　　要：近些年,随着水体的污染,剑水蚤出现在饮用水中的现象日益增多,对人体存在重大的安全隐患。传统的处理工艺无法完全去除水中剑水蚤,实验结果表明,用预氧化手段对剑水蚤进行滤前灭活,可以提高去除效果,并能实现剑水蚤的完全去除。选用实验水源为抚顺市大伙房水库来水为实验水源,通过向含有剑水蚤数量基本相同的烧杯内,分别投加有效氯含量相同的次氯酸钠和二氧化氯药剂,观察预氧化剂投加后对剑水蚤的灭活时间以及药液投加体积进行对比,最终确定最有效的药剂和投加量。In recent years,with the water pollution,the occurrence of Cyclops in drinking water is increasing day by day,which is a major safety hazard to human body.Traditional treatments cannot completely remove Cyclops,the experiment result shows that the removal effect can be improved and the complete removal of Cyclops can be achieved by inactivating Cyclops before filtration by means of pre-oxidation.The experimental water source is the water from DaHuoang reservoir in FuShun,by adding sodium hypochlorite and chlorine dioxide with the same effective chlorine content to the beaker containing the same number of Cyclops,after the addition of pre-oxidation,the inactivation time and dosage of soup were compared to determine the most effective pre-oxidation and dosage.
