为了解铜仁市城区供水水质情况,文章参照生活饮用水及地表水相关检测标准,对城区三座自来水厂的水源水和出厂水进行了为期两年的检测。结果显示,白马洞水厂、鹭鸶岩水厂、尖岩水厂水源均符合地表水Ⅲ类标准,出厂水各项指标均符合生活饮...为了解铜仁市城区供水水质情况,文章参照生活饮用水及地表水相关检测标准,对城区三座自来水厂的水源水和出厂水进行了为期两年的检测。结果显示,白马洞水厂、鹭鸶岩水厂、尖岩水厂水源均符合地表水Ⅲ类标准,出厂水各项指标均符合生活饮用水卫生标准。经2021年各水厂陆续优化改造后,各水厂出厂水平均浑浊度低于0.5 NTU,水质提升显著。 In order to understand the water quality of water supply in the urban area of Tongren City, this article refers to the relevant testing standards for domestic drinking water and surface water, and monitors the source water and effluent water of three water plants in the urban area for a period of two years. The results show that the source water of Baimadong Waterworks, Lusiyan Waterworks, and Jianyan Waterworks all meet the Class III standard for “Environmental quality standards for surface water” and all indicators of the produced water meet the “Standards for drinking water quality”. After the optimization and renovation of their respective, the average turbidity of the water produced by these waterworks has dropped below 0.5 NTU, marking a significant improvement in water quality.展开更多
