赤水河习酒镇段水质分析与评价

Analysis and Evaluation of Water Quality of Xijiu Town Section of Chishui River

通过对赤水河习酒镇段四个监测断面和该河段边上某酱香型白酒酿造企业的生产废水总排放口及经过该厂区的雨水排口等点位进行1年的水质特征跟踪调查,采用对标法对赤水河习酒镇段水质状况以及雨水排口、废水总排口水质进行评价分析。结果表明,赤水河习酒镇段水质均能达到地表水环境质量Ⅱ类水质标准,雨水排口水质均能达到地表水环境质量Ⅲ类标准,废水总排口水质均能达到行业排放标准。赤水河习酒镇段水质未受到该酱香白酒酿造企业的影响。总体上,赤水河习酒镇段水质呈现春、夏季优于秋、冬季的特点。

The water quality at four sampling sites along the Xijiu Town section of Chishui River,and the water quality at the wastewater outfall and rainwater outfall of a Jiangxiang Baijiu distillery on the bank of the Xijiu Town section of Chishui River was tracked for one year,and the water quality characteristics were analyzed and evaluated.The results showed that the water quality of the Xijiu Town section of Chishui River met the class II standard for surface water,the water quality at the rainwater outfall met the class III standard for surface water,and the water quality at the wastewater outfall met the industrial discharge standard.The water quality of the Xijiu Town section of Chishui River was not affected by the Jiangxiang Baijiu distillery.In general,the water quality of the Xijiu Town section of Chishui River is better in spring and summer than in autumn and winter.
