摘　　要：目的　观察城镇污水处理厂污水处理前后微生物数值变化 ,分析对环境的影响 ,探讨排放标准。方法　定点定时采集污水源水和经处理后的出厂水 ,按国家规定的方法检测细菌和病毒 ,同时收集理化指标检测数据。结果　出厂水菌落总数高达 72 0 0 0 0cfu/L :总大肠菌群和粪大肠菌群 >16 0 0 0个 /L ;源水肠道病毒阳性率为 5 8 33%出厂水肠道病毒阳性率为16 6 7%。结论　理化指标处理效果较好 ,细菌、病毒处理效果较差 ,应加强对城镇污水综合处理厂出厂水有关标准的研究。Objective To observe the change of microbial indexes caused by the treatment of municipal sewage treatment plant. To explore effects on the environment and the sewage discharge standard.Methods The samples collected from the source of sewage and the treated water at regular location and time were determinated according to the national standard.The monitoring data of physical-chemical indexes were also collected. Results In the treated water,the total count of bacteria was as high as 720 000 cfu/L.Both the total coliform and fecal coliform were>16000/L.The positive rates of enterovirus in the sewage and the treated water were 58.33%,16.67% respectively.Conclusion The improvement on physical-chemical indexes was good.The effect of treatment on bacteria and viruses was unsatisfactory. So the study on discharge standard of the treated water in municipal treatment plant should be strengthened.
