摘　　要：目的为农村改水摸底调查提供基础数据,对改水工程做出决策提供参考依据。方法全自治区按分层抽样方法选38个县作为监测对象,约78%的农村人口饮用集中式水厂的供水。按照《生活饮用水标准检验方法》(GB/T 5750–2006),对水样的17项指标进行检验。结果影响农村生活饮用水水质的主要因素是细菌污染及硫酸盐、氯化物、总硬度超标。结论农村水厂管网末梢水水质综合指标合格率较低,主要是水厂处理工艺不够完善,消毒不够规范等所致。加强对农村安全饮水工程的卫生学评价与全过程的质量验收,依设计要求完善水处理设施并加强运行管理。Objectives To investigate the real situation of rural water supply to provide basic data and reference materials for decision-making on water improvement projects. Methods Thirty eight counties of Xinjiang Autonomous Region were selected as representative monitoring points by stratified sampling method; 17 indicators were tested according to the Standard Examination Methods for Drinking Water( GB/T 5750-2006). Results Approximately 78 % of rural population had their drinking water from centralized water supply; the main factors affecting the quality of drinking water were bacterial contamination and the exceeded sulfates,chlorides and total hardness. Conclusions The qualified rate of composite indicators for peripheral water from rural water pipe network was low, the process for water treatment was not perfect, and the disinfection was not up to the standards. It is necessary to strengthen hygienic evaluation and check the quality of whole process according to the designed requirements to improve the operation and management of water treatment facilities for safe drinking water projects in rural areas.
