摘　　要：为解决原水中剑水蚤难以被水厂常规工艺有效去除的问题,分析了剑水蚤的生长因子,考察了PAC、PAM和FeCl3对浊度的去除效果和对蚤类的灭活效果,以及NaClO和ClO2对蚤类的氧化灭活效果,并模拟水厂实际运行工艺条件研究了混凝和预氧化的协调除蚤效能。结果表明,PAC在混凝效果和投加量两方面均优于其他2种混凝剂;ClO2的氧化性能优于NaClO,1 mg/L投药量时在5 min内即可灭活全部剑水蚤。In order to solve the problem that Cyclops is difficult to be effectively removed by conventional process in waterworks,the growth factors of Cyclops were analyzed.The removal effects of PAC,PAM and FeCl3 on turbidity and the fleas,as well as the oxidation and inactivation effects of NaClO and ClO2 on fleas were investigated.Finally,the coordinated flea removal of coagulation and preoxidation under the actual operation conditions of simulated waterworks was investigated.The results showed that PAC was better than the other two coagulants in coagulation effect and dosage,and the oxidation performance of ClO2 was better than NaClO.When the dosage of PAC was 1 mg/L,all Cyclops could be killed within 5 minutes.
