甘肃环县樊家川乡饮用水水源水质评价与分析

Evaluation and Analysis of Drinking Water Quality in Fanjiachuan Township,Huanxian County,Gansu Province

本文通过对甘肃省环县樊家川乡水源地地下水进行采样检测,分别采用单因子指数法和综合评价法对樊家川饮用水水源的水质进行评价与分析,检测结果为该地区Cr^(6+)超过《地下水质量标准》(GBT 14848-93)Ⅲ级标准3.3倍,建议在供水站采取生物材料吸附法增加水处理设施,活性炭吸附法,安装除铬填料装置,去除饮用水中Cr^(6+)。

In this paper,through the sampling and detection of groundwater in Fanjiachuan Township,Huanxian County,Gansu Province,the single factor index method and comprehensive evaluation method are used to evaluate and analyze the water quality of Fanjiachuan drinking water source.The test results show that the Cr 6+in this area exceeds the groundwater quality Standard(GBT 14848-93)Grade III standard by 3.3 times.It is suggested that the biomaterial adsorption method should be adopted in the water supply station to increase the water treatment facilities and activated carbon adsorption method.It is recommended to install a chromium removal packing device to remove Cr 6+from drinking water.
