目的了解安徽省农村生活饮用水水质卫生状况,为推进农村改水提供依据。方法采用现场环境卫生学调查与水质检测的方法。结果农村生活饮用水水源以地下水为主。2001年至2003年水质比较稳定,合格率以二级水为标准达到44.60%,以三级水为标准达到61.88%;感观指标和理化指标合格率较高,均在90%以上;丰水期水质比较稳定,枯水期水质变化相对比较大。结论安徽省农村水源污染有进一步加重的趋势,水质合格率偏低。需加强水源卫生防护和饮水消毒工作。
Objective To understand the sanitary status of drinking water quality in rural areas of Anhui Province and provide the basis for promoting rural water improvement. Methods The methods of on-site environmental hygiene investigation and water quality testing were adopted. Results The source of drinking water in rural areas is mainly groundwater. From 2001 to 2003, the water quality was relatively stable. The pass rate reached 44.60% based on the second grade water and 61.88% based on the third grade water. The passing rate of sensory index and physical and chemical index was higher than 90% Period of relatively stable water quality, dry season relatively large changes in water quality. Conclusion The water pollution in rural areas of Anhui Province is further aggravated, and the passing rate of water quality is low. Need to strengthen water sanitation protection and drinking water disinfection.
