目的研究农村饮用水现状,探讨改水工作的对策。方法对农村饮用水现状进行调查并结合饮用水监测点资料进行综合分析。结果全县农村饮用水以分散式供水为主,饮用人口占总人口的84.37%;主要水源类型为地下水、水库水、江河水。合格率以二级水为标准达到12.50%,以三级水为标准达到26.52%,但感官指标和理化指标均在93%以上,丰水期水质比较稳定,枯水期水质变化较大。结论微生物污染为当前农村饮用水污染的主要指标。提示需加强水源卫生防护和饮用水消毒管理工作。
Objective To study the current status of rural drinking water and to discuss the countermeasures of water diversion. Methods The status quo of rural drinking water was investigated and combined with drinking water monitoring point data for a comprehensive analysis. Results The county drinking water in rural areas to decentralized water supply, drinking population accounted for 84.37% of the total population; the main types of water for groundwater, reservoir water, river water. The passing rate is 12.50% for secondary water, 26.52% for tertiary water, but the sensory indices and physicochemical indexes are all above 93%. The water quality is stable in wet season and changes greatly in dry season. Conclusion Microbial contamination is the main indicator of drinking water pollution in rural areas at present. Prompt need to strengthen water sanitation protection and drinking water disinfection management.
