摘要
为了解决农村饮水安全问题,郑州市进行了农村饮用水水质评价.全市共布设255个水质取样点,水质检测项目约21项,以生活饮用水卫生标准作为水质评价标准.评价结果为:氟化物超标率为10.20%,主要分布在荥阳市北部、登封市西南、新郑市东南、中牟县南部;溶解性总固体超标率为23.81%,总硬度超标率为43.92%,硝酸盐(以氮计)超标率为21.68%,硫酸盐超标率为14.12%,氯化物超标率为10.20%,郑州市苦咸水、浅层地下水污染区域主要分布在巩义市伊洛河两侧、郑州市区—中牟县贾鲁河两侧、新密市—新郑市双洎河两侧、登封市颍河两侧、巩义市米河—上街区汜水河两侧.
For solving the problem of rural drinking water safety, drinking water quality evaluation in rural area in Zhengzhou city has been carried out.255 sampling points are chosen, and 21 components are detected. The evaluation criterion is drinking water sanitary standard. The resuits are： the over limit rate of fluoride is 10.20% ,and high-fluorine water mainly disperses in the north of Xingyang city,the west-south of Dengfeng city,the east-south of Xinzheng city and the south of Zhongmu county .The over limit rate of these components respectively are： total dissolved solid is 23.81 % ,total hardness is 43.92% ,nitrate nitrogen is 21.68% ,sulphate is 14.12% ,chloride is 10.20%. Bitter and shallow polluted water mostly disperses over both sides of Yiluo River, Jialu River, Shuangxu River, Ying River and Sishui River.
