摘要
为了探明重庆岩溶山区农村各种分散式供水模式饮用水的水质状况及影响因素,并在此基础上提高农村饮水质量,以重庆南川区南平镇石庆村为研究对象,通过实地水文地质调查、饮用水采样和室内分析相结合的方法,按照国家颁布的生活饮用水卫生标准(GB5749-2006),对研究区内8种不同供水模式下饮用水的水质状况进行对比研究,并就其影响因素展开深入探究。结果表明该研究区内饮用水水质状况总体上不容乐观。主要存在感官性状明显、pH偏高、部分离子浓度超标和细菌总数超标率高等问题。运用综合指数法分析后得出以雨水和坡面流为源水的饮用水水质较差,基本不适合饮用。雨水未被污染,经过治理可以饮用。地下水普遍受到人类的污染。
This paper chose a typical karst mountainous region at Nanping Town--Shiqing Village in the Nanchuan District of Chongqing as a study area in order to find out the drinking water quality conditions and factors affecting the non-central water of supply , and improve the drinking water quality. The main methods include field hydrogeologic survey, water sample collec- tion and comparative analysis in lab and so on. According to the Standards for Drinking Water Quality（GB5749-2006） , the au- thors analyed the drinking water quality for eight kinds of different modes of water supply. The results showed that the drinking water quality situation is not optimistic, the main problems are obvious sensory traits, higher pH, some exceeded ion concentration, and exorbitant bacteriological indicators. Using the composite index method, we concluded that the water quality of collected rainwater and overland flow is worst, which are not suitable for drinking. The uncontaminated rainwater was drinkable through some treatment processes. Groundwater has been polluted by human activities.
