滁河全椒段河流水质污染评价及驱动因子解析

Temporal Variation of Water Quality and Driving Factors in Chuhe Watershed of Quanjiao

以2014—2015年滁河流域全椒段水质监测数据为基础,选取9类影响水质的污染因子,利用单因子指数评价法分析流域水质演化趋势,并对水质的驱动因子进行解析。结果表明,2014—2015年滁河全椒段水质污染严重,主要污染物是氨氮、化学需氧量(COD)。滁河流域污染主要来源于工业、农业及畜禽养殖污染废水的排放。

Based on the water quality monitoring data from Quanjiao section in Chuhe River basin in 2014 and 2015, selected nine kinds of pollution factors affecting water quality, utilized single factor index evaluation method to research basin water quality evolution trend of and an-alyzed driving factors of water quality. According to the result, the water in Quanjiao section was contaminated seriously by main pollutants, ammonia nitrogen and COD from 2014 to 2015, which mostly came from the polluted wastewater discharge of industrial, agricultural and live-stock.
