安徽省集中式供水单位卫生现状调查

Investigation of Sanitary Status of Waterworks for Centralized Water Supply in Anhui Province

目的了解安徽省集中式供水单位卫生现状,为进一步贯彻实施GB5749—2006《生活饮用水卫生标准》提供对策。方法2008年4—11月,对安徽省全部市级市政水厂、县级市政水厂、市级企业自建水厂和乡镇水厂的卫生现状及水质自检能力进行了调查。结果四类水厂水源水达到Ⅲ类水质标准的比例均在70%以上;在卫生管理方面,市级市政水厂总体好于其他水厂;四类水厂的水质完全处理率分别为80.63%,73.78%,58.12%和60.46%;检验设备满足需要率分别为77.77%,42.99%,38.18%和13.77%;119家市政水厂的水质检测能力主要集中于感官指标、一般化学指标和微生物指标,毒理学指标、消毒剂指标、放射性指标和非常规项目检测可开展率分别为17.65%,26.68%,15.97%和3.49%。结论安徽省各类集中式供水单位在卫生管理方面有待加强,水质处理工艺需要进一步完善和改进,水质自检能力亟待提高。

Objective To know the sanitary status of waterworks for centralized water supply in Anhui province, and try to enhance the implementation Standards for Drinking Water Quality （GB 5749-2006）. Methods From April to November in 2008, the hygienic status and water quality self-test capacity of the waterworks at city, county, enterprise and town levels were investigated. Results As for the source water, over 70% of waterworks were up to the Grade Ⅲ standard. In the hygienic management and water treatment process, the city level water workswere better. The rates of complete water treatment were 80.63%, 73.78%, 58.12% and 60.46%, respectively for different level water works. The rates of the water quality test equipments fulfilled were 77.77%, 42.99%, 38.18% and 13.77% respectively. For water quality test, the 119 waterworks only focused on the aesthetic,general chemical and microbiological indexes. The performance rates of toxicological indicators,disinfectants indicators,radioactive indicators and other indicators were 17.65% ,26.68%, 15.97% and 3.49% ,respectively. Conclusion Hygienic management of waterworks of levels for centralized water supply in Anhui province needs to be strengthened, and the water treatment process needs to be improved, the capacity building for self-test of water quality in the waterworks needs to be enhanced.
