2011—2013年荆门市农村安全饮水工程水质监测结果

Water quality monitoring results of safe rural drinking water project in Jinmeng City from 2011-2013

目的通过对荆门市农村饮水工程水质进行监测，了解该市辖区农村安全饮水工程水质现状，保障农村居民的饮水安全。方法依据GB5749—2006（（生活饮用水卫生标准》对2011—2013年辖区内农村安全饮水工程水质监测结果进行分析和评价。结果2011—2013年荆门市辖区域农村安全饮水工程水质总体合格率为52．96％。其中，感官性状和一般化学指标合格率较高，达88．33％～100．00％；微生物指标合格率较低，仅为62．84％～81，67％；毒理学指标全部合格。不同水源类型、不同处理方式水质合格率差异有统计学意义（均P〈0．05）；不同水期水质合格率差异无统计学意义。结论目前农村安全饮水工程水质合格率较低，难达到卫生学意义上的“安全饮水”，建议加强农村安全饮水工程水质监督监测，加强农村安全饮水工程管理，饮水工程应完善和正确使用消毒设施，真正做到保障农村居民的饮水安全。

[Objective] To understand the current status of rural safe drinking water projects in Jingmen City via water quality monitoring,and protect the safety of drinking water for rural residents. [Methods] According to ＂Drinking Water Hygiene Standards＂ （GB 5749-2006）, the 2011-2013 water quality monitoring results of safe drinking water project were analyzed and evaluated.

All toxicology indicators were qualified. The qualified rates were significantly different between water of different sources and different treatments （all P〈0.05）. The qualified rate of water was not significantly different between seasons. [Conclusion] Currently, the qualified rate of safe drinking water project in relatively low in rural area. The water quality can not meet the hygiene definition of safe drinking water. It is recommended to strengthen the rural safe drinking water project quality supervision and monitoring,to strengthen the management of rural safe drinking water projects, to improve drinking water projects management,to correctly use disinfection facilities and to truly protect the safety of drinking water for rural residents.
