【摘要】 目的全面了解江苏省农村集中式供水水质的卫生现状,为提高江苏省农村饮用水卫生管理水平,制订改水决策提供科学依据。方法对江苏省所有57个县(市、区)农村集中式供水水源类型、取水方式、水质处理情况等进行现场调查。按照GB/T 5750—2006《生活饮用水标准检验方法》对水样进行采集、保存和检测,检测项目包括感官性状指标、一般化学指标等共19项。依据GB 5749—2006《生活饮用水卫生标准》对水质结果进行评价。结果我省集中式供水水源以地下水为主,水样合格率为49.45%。不同水源类型比较,地面水水样合格率高于地下水(P<0.01),地面水水样色度、浑浊度、臭和味、肉眼可见物、耗氧量、氨氮、总大肠菌群、耐热大肠菌群不合格率高于地下水(P<0.01),地下水水样总硬度、铁、锰、硫酸盐、氯化物、溶解性总固体、硝酸盐不合格率高于地面水(P<0.01)。结论江苏省农村集中式供水水样合格率较低,水质处理设施有待进一步完善,应根据不同水源类型采取针对性措施提高水样合格率,保障广大农村人口饮水安全。更多还原

【Abstract】 Objective To explore the sanitation of central water supply in rural area of Jiangsu province.Methods All the counties in Jiangsu province were selected to build the monitoring network of rural drinking water quality.The water samples were evaluated complying with the standard protocol of drinking water quality test(GB 5749—2006).Results The qualified rate of water samples was 49.45%。Analyzed by different water source type,the qualified rate of surface water is higher than ground water(P<0.01).The unqualified rate of most water sample indices is statistically different between surface water and ground water.Conclusion The water samples reveals lower qualified rate,which should be improved by specific measures according to different water source type.更多还原
