Analysis of Waterworks Sanitation and Its Crucial Influence Factors at Prefecture and County Levels of Suzhou City

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 Analyzing the sanitation status and its crucial factors of SuZhou water supply in order to strengthen sanitation management of water supply. Methods water quality was examined and analyzed in 2000. Results water supply of SuZhou city is the ground water from 70 to 320meters deep without decontaminate and disinfection. It revealed that there was 13.3% chance of pollution within 30 meters of water source and 53.33% chance of farm chemical fertilizer pollution within 100 meters of water source. The qualified rate of 131 water samples was 45.04%. The crucial influence factors included fluoride, accounted for 44.19%, coliform, 17.44%, bacteria, 13.95%, high water rigidity, 11.63% and excess sulphate 9.30%.
