摘　　要：对城市中水回用过程中的大肠菌群进行灭活实验.选用呼和浩特市辛辛板污水处理厂的二级出水,采用化学方法对大肠菌群进行控制,选取次氯酸钠、过氧化氢和新洁尔灭3种杀菌药剂对杀菌效果进行实验研究,得出3种药剂对大肠菌群的最佳作用剂量和最佳作用时间.实验结果表明,中水用于工业循环冷却用水、景观环境用水、城市杂用水时,大肠菌群的杀灭率分别达到91.6%,95.8%,99.9%以上时,才能符合安全使用的要求.The coliform in reusing city＇s reclaimed water is studied in this paper. The secondary effluent of municipal sewage treatment plant in Xinxinban of methods, the bactericidal effect by three bactericides, that are so bromo geramineto,is studied. According the test, their optimal Hohhot as study sample, Using chemical dium hypochlorite, hydrogen peroxide and additive quantities and operating time are gained. If the reusing intermediate water is used for the circulating cooling water, the urban landscape water and others,the antiseptic rate of coliform should be above 91.6% ,95.8% and 99.9% ,thus it can meet the requirements of safe use.
