【摘要】：目的全面了解江苏省农村饮用水水质现状,为保障饮水水质安全提供参考。方法于2013年8-9月在江苏省随机选择72座农村集中式供水水厂,对出厂水进行106项水质全分析。结果 72份水样合格率为62.50%,主要不合格指标共14项,其中常规指标11项,非常规指标3项,主要不合格指标包括微生物指标(总大肠菌群、耐热大肠菌群、贾第鞭毛虫)、毒理学指标(三氯乙醛、氟化物、亚氯酸盐、锑)、感官性状和一般化学指标(浑浊度、铝、锰、耗氧量、铁、硫酸盐、总硬度),微生物不合格水样中未消毒水厂占52.38%。结论江苏省农村饮用水以微生物污染为主,同时存在化学性污染。应进一步查明污染来源,积极采取措施加强水厂管理,完善供水设施,保障饮水安全。
[Abstract]:Objective to understand the present situation of drinking water quality in rural areas of Jiangsu Province and to provide reference for ensuring the safety of drinking water quality. Methods 72 rural centralized water supply plants were randomly selected in Jiangsu Province from August to September on 2013. Results the qualified rate of 72 water samples was 62.50, and the main unqualified indexes were 14, among which 11 were routine indexes and 3 were unconventional indexes. The main unqualified indexes included microbial index (total coliform group). Heat-resistant coliform, Giardia flagellate, toxicological index (trichloroacetaldehyde, fluoride, chlorite, antimony, sensory properties and general chemical parameters (turbidity, aluminum, manganese, oxygen consumption, iron, sulfate, etc.), The total hardness was 52.38. Conclusion the drinking water in rural areas of Jiangsu Province is mainly polluted by microorganisms, and chemical pollution exists. The source of pollution should be further identified and measures should be taken to strengthen the management of water works. Improve water supply facilities to ensure drinking water safety.
