目的了解高淳县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。方法对全县所有集中式供水单位的出厂水和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。结果高淳县2009—2011年水质各项指标合格率呈明显上升趋势,但仍处于很低水平;市政供水合格率高于镇和村级供水合格率。结论高淳县饮用水质安全状况不容乐观。菌落总数、浑浊度、耗氧量等是影响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,同时做好水源保护,加快区域供水建设进程,保证饮用水安全。
Objective To understand the sanitary status of drinking water quality in urban and rural areas of Gaochun County and to make suggestions for improvement according to the existing problems. Methods Periodic sampling of selected sampling points of ex-factory water and pipe-end water of all centralized water supply units in the county was conducted and tested and evaluated according to national standards. Results The passing rate of various indicators of water quality in Gaochun from 2009 to 2011 showed a clear upward trend, but still at a very low level. The passing rate of municipal water supply was higher than the passing rate of water supply at towns and villages. Conclusion Gaochun drinking water quality and safety is not optimistic. The total number of colonies, turbidity, oxygen consumption, etc. are the main factors affecting the passing rate of drinking water. Proposed to strengthen the centralized water supply in rural areas of water regulation, health management and disinfection of water quality, while doing a good job of water protection, speed up the process of regional water supply to ensure the safety of drinking water.
