目的了解某部自备生活饮用水水源卫生状况。方法对某部51个自备水源进行现场采样并检测总大肠菌群、耐热大肠菌群、大肠埃希氏菌、菌落总数。检测方法依据《生活饮用水标准检验方法》(GB/T 5750.12-2006),评价标准按《生活饮用水卫生标准》(GB 5749-2006)中规定的限值进行评价。结果 51个水源微生物学指标超标率为45.10%(23/51)。其中,总大肠菌群阳性率为45.10%(23/51),耐热大肠菌群阳性率为23.53%(12/51),大肠埃希氏菌阳性率为7.84%(4/51),菌落总数阳性率为3.92%(2/51)。结论受到污染的水源主要是未经水源水质综合整治的水源。应尽快采取有效的综合治理措施,同时加大饮水卫生监督检测力度,完善水源管理制度,减少水源污染。
Objective To understand the hygiene status of a self-provided drinking water source. Methods A total of 51 self-provided water samples were collected and tested for total coliforms, heat-resistant coliforms, Escherichia coli and colonies. The testing method is based on the Standard Test Method for Domestic Drinking Water (GB / T 5750.12-2006), and the evaluation standard is evaluated according to the limit stipulated in the Standard for Drinking Water Quality (GB 5749-2006). Results The over-standard rate of 51 water microbial indicators was 45.10% (23/51). Among them, the positive rate of total coliform was 45.10% (23/51), the positive rate of heat-resistant coliform was 23.53% (12/51), the positive rate of Escherichia coli was 7.84% (4/51) The positive rate was 3.92% (2/51). Conclusions The water source that is polluted is mainly the water source that has not been comprehensively rehabilitated by water quality. Effective measures should be taken as soon as possible, while increasing the intensity of drinking water sanitation supervision and testing, improve water management system to reduce water pollution.
