宁夏银川东郊水源地地下水水质评价与应对措施

Evaluation of Underground Water Quality of the Water Source and Countermeasures in the Eastern Suburbs of Yinchuan,Ningxia

为提高饮用水水源地地下水水质,采用生活饮用水卫生标准检验方法,对银川东郊6个水源地地下水采样分析和评价,结果表明:银川东郊水源地地下水受到一定程度的污染,监测锰、铁、硫酸根、总硬度、硒超标,并提出建议。坚持“注重源头控制、强化监控手段、污水集中处理、完善应急响应系统建设”原则,落实应对措施。

In order to improve the underground water quality of drinking water source,the research adopts the testing methods of drinking water hygienic standard,and analyzes and evaluates the underground water samples in 6 water sources in the eastern suburbs of Yinchuan.The results show that the underground water in the eastern suburbs of Yinchuan has been polluted to a certain extent,with an exceed standard of manganese,iron,sulfate radical,total hardness and selenium.Then the suggestions are put forward,i.e.to adhere to the principle of“focusing on source control,strengthening supervision method,centralized processing of waste water,and perfecting emergency response system”,and implement countermeasures.
