目的 分析宿州市市、县级自来水水厂供水卫生现状和影响因素 ,以加强我市集中式供水卫生管理。方法 采用现场调查和对 2 0 0 0年水质抽样检查结果进行分析。结果 宿州市自来水水源均为 70～32 0米深层地下水 ,没经净化、消毒 ,直接向管网用户供水。所查水源 30m范围内有污染源的占 13.3%,10 0m范围有农田使用化肥的占 5 3.33%。抽查 131份水样合格率为 45 .0 4%,影响水质的主要超标指标是氟化物占 44 .19%,总大肠菌群占 17.44 %,细菌总数占 13.95 %,总硬度占 11.6 3%,硫酸盐占 9.30 %。结论 宿州市城镇集中式供水面临的主要问题是改水降氟、饮水消毒和水源卫生防护。
Objective To analyze the present situation and influencing factors of water supply and sanitation of tap water factories in Suzhou city and county level so as to strengthen the centralized water supply and sanitation management in our city. Methods The field survey and sampling results of water quality in 2000 were analyzed. Results The tap water sources in Suzhou City were all deep groundwater of 70 ~ 320 meters. Without purification and disinfection, tap water was directly supplied to users in the pipe network. The sources of pollution within 30m of the surveyed water sources accounted for 13.3% of the total, while the areas of 100m of agricultural chemical fertilizers accounted for 5 3.33% of the total. A total of 131 samples with a water quality pass rate of 45.0% were selected. The main indexes that exceeded water quality were fluoride (44.19%), total coliforms (17.44%), bacteria (13.95%), total hardness Sulfate accounted for 9.30%. Conclusion The main problems faced by urban centralized water supply in Suzhou City are water and fluoride reduction, drinking water disinfection and water sanitation protection.
