摘要
目的了解句容市城区和农村生活饮用水水质卫生状况,针对存在的问题提出改进建议。方法对全市所有城区和农村集中式供水的源水、出厂水、管网末梢水选定采样点,定期采样按国家标准进行检测与评价。结果所监测的源水均达地表水Ⅲ类以上标准,出厂水、管网末梢水的合格率分别为35.36%、27.51%。市政供水合格率高于乡镇供水合格率。结论句容市虽集中式供水覆盖率达95.78%,但农村的水质合格率一直较低,浑浊度、耗氧量和总大肠菌群、耐热大肠菌群、菌落总数是影响农村生活饮用水合格率的主要因素。建议加强农村集中式供水的制水规范、卫生管理和水质消毒,保证饮用水安全。
Objective To investigate the sanitary conditions of drinking water quality in the urban and rural areas of Jurong,and to put forward some suggestions for improvement. Methods We selected the sampling points of all the centralized water supply source water,chlorinated water,and tap water in the urban and rural areas of Jurong.According to the national standards,we regularly tested and evaluated the water samples. Results The surveillance results of the source water reached the surface water more than the standard Class III,the eligible rates of chlorinated water and tap water were 35.36% and 27.51%,respectively.The qualified rate of municipal water was higher than that of township water supply. Conclusions The coverage rate of centralized water supply was 95.78% in Jurong,but the pass rate of the water quality in the rural areas was lower.Turbidity,oxygen consumption and microbial indicators of total coliform group,heat-resistant coliform bacteria and the total numbers of colony were the main factors to affect the pass rate of the water quality in the rural areas.The results suggest that it is necessary to strengthen the standards of centralized water supply system,health management and water disinfection in the rural areas,and to ensure the safety of drinking water.
