摘要
紫外消毒是当前污水处理厂用于杀灭粪大肠菌群的主要消毒技术之一。对紫外消毒后水样在不同保存条件、不同保存时间后的粪大肠菌群数检测,发现粪大肠菌群数发生明显变化。据此探讨提出水样的采集、保存和送检要求,提出针对GB 18918—2002中粪大肠菌群数检测的调整建议、环保对粪大肠菌群数检测和执法建议。
Ultraviolet disinfection is one of the main disinfection technologies for killing of fecal coliforms （FC） in sewage treatment plants. The number of FC was found to change significantly when the tests on FC in the water samples after ultraviolet disinfection were carried out under different storage conditions and different preservation times. According to the test results and analyses, the requirements for collection, preservation and inspection of water samples were put forward, giving suggestions to adjust the tests on FC in GB 18918 -2002 and the monitoring process of the environmental protection agency.
