摘要
随着我国西北地区城市化进程的加快,地下水污染问题日益突出,地下水环境质量直接影响当地人民的生产生活。虽然前人对西北地区地下水污染情况已有了大量的研究,但缺乏较为宏观的概述和规律性的总结。因此,文中对西北地区各省市及自治区的各类型污染超标情况进行了调研。在详实的数据基础上,参照我国《地下水质量标准》(GB/T 14848—2017)和《生活饮用水卫生标准》(GB 5749—2006),阐述了各地区需注意的水质超标风险,分析了各地区地下水污染的原因、污染物的来源、需采取的治理措施。文章从气候条件、地形地势、地质构造等自然因素和农业灌溉、工业排放和超量开采等人为因素方面,总结了各类型超标风险的地区性规律,归纳了各类型污染的地下水化学特征。
With the acceleration of urbanization in the northwest regions of China, the issue of groundwater pollution has becoming increasingly severe, and the quality of groundwater environment directly affects the industries and life of local people. Lots of researches regarding to groundwater pollution of these regions have been studied, however relatively macroscopical overview and regularity summary are needed. Therefore, the situations of various pollutions of groundwater that not meet the standards in the provinces and autonomous regions of these areas have been investigated in this paper. Based on detailed survey and with reference to Standard for Groundwater Quality(GB/T 14848—2017)and Standard for Drinking Water Quality(GB 5749—2006), the security risks of water quality should raise attention. Meanwhile, the causes of contamination, the sources of pollutants, and management measures to be taken in each region have been analyzed in this paper. In the light of natural factors such as climate conditions, topography and geological structure and human factors such as agricultural irrigation, industrial discharge and excessive exploitation, the regional patters of various risk and the water chemical characteristics of various contaminations in groundwater have been summarized.
