西南岩溶石山地区水窖水质状况及保护措施——以云南木美地下河流域为例

Present state and protection of water quality of water cellar in karst mountain areas of South China: a case study on Mumei subterranean stream basin

以云南省木美地下河流域为例,就西南岩溶区水窖的水质状况进行分析,结果表明水窖的水质状况尚为良好。由于水窖建材及水源类型等的不同,导致水窖水质的差异。水窖的污染类型有四类:颜色、肉眼可见物异常;超长时间放置导致生物性污染;pH值呈碱性;生活垃圾和污水引起HCO-3,Ca2+,Na+,Cl-等离子超标。建议加大力度,加强水源地的保护,改善水窖的水质。

The water quality of water cellar in karst areas of South China is analyzed in the case of Mumei subterranean stream basin, showing good results. The water quality of water cellars differs because of the different materials and water sources of water cellars. The pollution types in water cellar include the abnormity in color and macroscopic matter, biological pollution due to long-time placement, the alkalinity of pH, and some ions, exceeding the standard, such as HCO^-_3,Ca^(2+),Na^+, and Cl^-. It is suggested that the protection of water source area should be strengthened to improve the water quality in cellars.
