石家庄市地下水污染特征及其与超量开采的关系

Features of groundwater pollution and its relation to overexploitation of groundwater in Shijiazhuang city

石家庄市地下水污染以常量组分的含量和指标升高为主要特征, 污染源主要来自城市污水, 这在我国城市地区地下水污染问题中极具代表性。本文在分析污染特征的基础上, 对地下水污染与超量开采的关系进行了研究和探讨, 揭示了超量开采加剧地下水污染进程的机理, 进而提出, 超量开采地下水是导致地下水污染的重要诱导因素。

The groundwater pollution in Shijiazhuang city is characterized by an excess of some components and parameters over permitted values.The main pollutants are originated from the city sewage which is quite typical for groundwater pollution in many cities of China.On the basis of analyzing features of groundwater pollution,the relationship between the groundwater pollution and the groundwater overexploitation is discussed in this paper,and the mechanism of intensifying the pollution by overexploitation has been revealed.Finally,it is proposed that the overexploitation of groundwater is an important inducing factor leading to the groundwater pollution in cities.
