山西岩溶泉域水污染现状、趋势与防治对策研究

STUDY ON THE POLLUTION STATUS, TREND AND PROTECTION MEASURE OF SHANGXI KARST SPRINGS

山西岩溶泉域环境脆弱,水煤资源共存,加上工业和生活"三废"的不合理排放,造成了岩溶泉域局部地段出现点状和面状污染,主要表现为岩溶水的总硬度、硫酸盐、溶解性总固体、铁和COD等污染物含量普遍增高,而且污染还有逐年加重的趋势。为了有效遏制泉域岩溶水的污染,提出了严格控制地表污染源、提高资源再生利用水平、减少污染物排放量,以及建立岩溶水水源地环境保护区等综合治理措施。

The environment is fragile in karst spring basin, Shanxi province. The coal and water resources exist together there. The unreasonable discharge of industrious production and daily three wastes lead to pollution on spot or in large-range locally in the basin. The pollution mainly assumes the increases of the hardness, sulphate, dissolved total solids and iron as well as COD, etc.. And the case trends to be more serious. In order to limit the pollution, a series of synthetic ways are put forth as follows - the pollution source from ground surface should be controlled rigidly, the using level of the resources be enhanced, discharging amount be decreased, and protecting area for karst water be built etc..
