【摘要】 目的为了保障黔西南州农村人口的饮水卫生安全,及时掌握农村饮用水水质变化动态,为政府提供决策依据。方法按《生活饮用水标准检验方法》(GB/T 5750—2006)进行采样检测,按《生活饮用水卫生标准》(GB 4789—2006)对检测结果进行评价。结果 2010年-2013年水质总体合格率为27.69%,合格率逐年提高,枯水期的合格率高于丰水期;感官性状和一般化学指标的合格率为94.07%、毒理指标的合格率为100%,微生物指标的合格率为29.29%;由于地形原因,地下水和地表水均易受到污染;农村饮用水处理工艺不完善,完全处理占14.05%,使用消毒剂消毒占12.04%。结论黔西南州农村饮水安全工程生活饮用水总体水质较差,主要原因是水处理工艺和消毒设施不完善。因此,需要完善水处理工艺和消毒措施,保证农村居民饮用水安全。

【Abstract】 Objective To understand the hygienic situation of water quality in rural areas of Qianxinan,so as to know the quality change of the drinking water and provide strategic basis for government. Methods The water sample was collected and detected according to the standard testing methods for drinking water( GB / T 5750—2006),and water quality was evaluated in accordance with the drinking water health standards( GB 5749—2006). Results From 2010 to 2013,the qualified rate of water quality increased year by year. The total qualified rate of water quality was 27. 69%. The qualified rate of drinking water quality in dry season was higher than that in wet season. The qualified rates of sensory traits and general chemical indicators,toxicological indicators and microbiological indicators were 94. 07%,100% and 29. 29%,respectively. The groundwater and surface water were susceptible to contamination due to the topography factors. The disposal technology of rural drinking water was not enough perfect,only 14. 05% of the water samples were processed with complete treatment and 12. 04% of the water samples were processed with chlorination treatment. Conclusion The main reason for the poor water quality in rural areas of Qianxinan might be unperfect treatment and nonstandard disinfection. Therefore,it is necessary to perfect the water treatment technology and facilities,and to reinforce disinfection work for insuring the sanitary safety of rural drinking water.
