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。
Objective To understand the status quo of drinking water quality in rural areas of Jiangsu Province in an all-round way and provide references for the protection of drinking water quality and safety. Methods Eighty-eight rural centralized water supply plants were randomly selected in Jiangsu Province from August to September in 2013, and 106 water quality analyzes of the finished water were conducted. Results The qualified rate of 72 water samples was 62.50%. There were 14 main unqualified indicators, including 11 routine indicators and 3 unconventional indicators. The main unqualified indicators included microbial indicators (total coliforms, heat-resistant coliforms, Giardiasis), toxicological indicators (chloral, fluoride, chlorite, antimony), sensory and general chemical indicators (turbidity, aluminum, manganese, oxygen consumption, iron, sulphate, total Hardness), unqualified microorganisms did not disinfect water samples accounted for 52.38%. Conclusion The drinking water in rural areas of Jiangsu Province is dominated by microbial contamination, while chemical pollution exists. Should further identify sources of pollution, and actively take measures to strengthen water management, improve water supply facilities, to ensure drinking water safety.
