摘要
根据2015年～2018年西安境内10条主要河流入渭河口断面水质监测资料,采用改进的模糊综合评价法,对西安近四年主要河流的水质进行评价,并结合流域实际情况对计算结果进行分析。结果表明:近四年新河、幸福渠、漕运明渠水质得到大幅提升,但皂河污染仍旧较重,需加大治理力度。黑河水质较优,需进一步保持;临河、涝河水质呈规律性季节变化,应进一步强化管理。泾河水质呈无规律波动,需加强与上游市段相关部门沟通;2015年、2016年沣河与灞河水体污染不断加剧,自2017年以来,水质得到逐步改善,需进一步提高污水处理水平,减少污染物排放量。
According to the water quality monitoring data in the section of Weihekou which entered by lO major rivers in Xi＇an from 2015 to 2018, the article is based on the improved fuzzy comprehensive evaluation method to evaluate their water quality and also combine with the actual situation of the river basin to analyze the calculation results. The results show that the water quality of Xinhe, Xingfu and Caoyunminh channels has been greatly improved in the past four years, but the pollution of the Zaohe River is still heavier and needs to be strengthened. The water quality of the Heihe River is superior and needs to be further maintained. The water quality of the Linhe River and the Laohe River are seasonally changing, and management should he further strengthened. The water quality of the Jinghe River is undulating, and it is necessary- to strengthen communication with relevant departments in the upstream market. In 2015 and 2016, the pollution of the Banghe River and the Babe River has been intensified. Since 2017, the water quality- has been gradually improved, and the level of sewage treatment needs to be further improved in order to reduce pollutant emissions.
