萍水河环境水质现状评价与分析

The Evaluation of Water Quality of Pingshui River

对萍乡市萍水河8个断面进行监测,并对河流断面水质进行评价和分析。结果显示,萍水河水环境质量基本保持稳定,达国家地表水环境质量Ⅱ类标准,其中南门桥断面综合污染指数最高,其污染主要来源于固定的几个生活污水的排放。萍水河从上游和雁桥断面到中游南门桥断面,水体沿程恶化,从中游南门桥到下游金鱼石断面水质则逐渐好转。

The water quality of Pingshui River was evaluated and analyzed by monitoring 8 sections of the river. The results show that the environmental quality for the river remains stable and up to Class II standard for surface water environmental quality. However, the comprehensive pollution index in Nanmenqiao section appears the severest, mainly caused by domestic sewage. The water quality deteriorates from the upper-stream to Yanqiao section to Nanmenqiao section. But the water quality of the downstream is gradually improved from Nanmenqiao section to Jinyushi section.
