仁怀茅台清草坝岩溶地下水系统污染特征及成因分析

Pollution Characteristics and Cause Analysis of Karst Groundwater System in Renhuai Maotai Qingcaoba

赤水河支流清草坝溪沟岩溶地下水受到污染,本文通过水文地质调查、水质采样分析、物探等方法进行综合研究,查明研究区存在两条独立的岩溶地下水系统,确定了主要污染因子,并指出污染源主要为酿酒作坊和煤矿污水,提出了源头控制、末端处理的修复建议,对防治该岩溶系统污染具有借鉴意义。

The karst groundwater in the Qingcaoba stream ditch,a tributary of the Chishui River,is polluted.Through comprehensive research methods such as hydrogeological investigation,water quality sampling and analysis,and geophysical prospecting,this paper identifies two independent karst groundwater systems in the study area,determines the main pollution factors,and points out that the main pollution sources are winemaking workshops and coal mine sewage.Repair suggestions of source control and end treatment are put forward,which have reference significance for preventing and controlling pollution of this karst system.
