摘　　要：目的了解泰州市农村饮用水水质状况,探讨泰州市农村饮水安全的影响因素。方法按照随机抽样的总原则兼顾水源类型、水处理方式、水厂规模、各地经济发展水平、距离等因素,2009~2013年在泰州市下辖4个监测县选取农村集中式供水水厂为监测点,每个监测点于枯水期与丰水期各采集出厂水与末梢水水样1份,每份水样均经19项指标检测。检测结果输入Excel 2007建立数据库,使用SPSS 17.0进行水质影响因素的Logistic回归分析。结果农村饮水安全工程、水源类型、水厂运营时间及地区因素对水质结果产生了较为明显的影响（p〈0.05）,农村饮水安全工程对水质结果的贡献相对较大。结论影响泰州市农村饮用水水质的主要因素是水处理设施、设备老化,水厂常规水处理工艺未落实,应加快农村饮水安全工程建设并切实落实常规水处理工艺;其次是地表水水源污染较为严重,建议保护水源。Objective To learn about the status and investigate the influence factors of Tai Zhou rural drinking water quality. Methods According to the general principle of random sampling, following the types of water source, water treatments, scales of water plants, local economic development level and distance, the monitoring points were selected respectively in four county-level cities from 2009 to 2013. Each point collected both one product water and one tap water in both dry season and wet season, and then each water sample was tested by 19 indicators. Test results were entered using Excel2007 to establish a database and processed Logistic regression analysis using SPSS 17.0. Results Rural drinking water safety project, water source, waterworks operation time and district presented more obvious influence on water quality results（p 0.05）, while the rural drinking water safety project relatively contributed more to the water quality.Conclusion The main factors influencing the rural drinking water were failing to carrying out the water common treatment process, water treatment facilities and equipments aging; secondly was the serious pollution of surface water. Therefore, we suggest controlling the pollutant emissions, protecting water sources, at the same time, earnestly implementing the conventional water treatment process.
