贵州农村人畜饮用水水质类型及保护对策探讨

对贵州省农村微型水利工程所拦蓄的浅层地下水、浅层地下水露头和屋面雨水等供人畜饮用水源的水质状况作了抽样分析和深入的调查.结果表明,示范区内人畜饮用水水源点的水质细菌学指标均大幅超标,而以屋面雨水的细菌学指标超标最严重.区内不同水源点造成水样细菌学指标超标的原因不尽相同.通过分析不同水源点造成污染的原因,根据不同类型的污染方式和水质类型分别提出了保护喀斯特农村人畜饮水安全的可行性保护与对策.

Water quality type of the drinking water and protective countermeasures in the rural of Guizhou Province

By the thorough investigation and sampling analysis of water-quality condition of shallow ground water and the point of shallow ground water emergence, as well as the roofing rain-water which dammed up in rural demonstration plot miniature hydraulic engineering of Guizhou. The result shows that the bacterial indexes of the drinking water in demonstration plot largely exceed the allowed figures, the roofing rain-water is the worst of all. The causes of the bacterial indexes excess of the drinking water in demonstration plot are not the same. By analyzing the causes of water contamination, respectively, we also put forward the feasible protective countermeasures of water security according to the difference of water-quality types and the style of contamination.
