调水对虹口区河道水质影响的分析

Analysis of the Influence of Water Transfer on the Water Quality of the River in Hongkou District

基于2017年04月和07月六次调水前后监测断面水质的高锰酸盐指数、氨氮、总磷等实际监测数据,分析并探索了调水工程对河湾和河道水质的影响。结果表明:由于污染物累积和底泥翻动,河湾处主要污染物浓度升高,而河道中线水质改善,说明调水可以在一定程度上改善河道水体水质。因此从长远来看,调水对水质改善有一定的贡献。

According to the actual water quality monitoring data of permanganate index,ammonia nitrogen and total phosphorus during six water diversions in April and July 2017,the effects of water diversion projects on the water quality of bays and rivers were preliminary explored.The results show that the concentration of pollutants in the bay increases due to the accumulation of pollutants and sediment turnover,while the water quality in the middle reaches of the river improves,which proves that water diversion can improve the water quality of the river to a certain extent.Therefore,in the long run,water diversion still contributes to the improvement of water quality.
