城市路面径流及CSOs污染特性的研究

对洛阳市路面径流及合流制溢流污水(CSOs)的水质进行了为期4个月的监测,监测指标包括CODcr、溶解态CODcr、SS、NH3-N、TP。结果表明,CSOs中各项指标含量大于路面径流;初期径流污染物浓度大,随着降雨历时的延长,各污染物浓度大幅度下降并趋于稳定;径流中主要污染物为SS、CODcr和NH3-N,通过对SS和CODcr的相关性分析以及总CODcr和溶解态CODcr含量的比较,得出SS是CODcr的主要贡献等。建议对于污染较严重的初期雨水径流可以采用弃流的方法进行处置。

Urban Road Runoff and Pollution Characteristics of CSOs

Luoyang,road runoff and Combined Sewage Overflow(CSOs) conducted a water quality of a 4-month monitoring,monitoring indicators include dissolved,,,,.The results show that,CSOs in the target content more than road runoff;the initial runoff pollutant concentration,as the rainfall duration increases,a significant decline in the concentration of each pollutant and stabilized;runoff of major pollutants,and,through the right and the correlation analysis and comparison of the total dissolved concentration,the main findings and the contribution.Recommended for the more polluting stormwater runoff in the early stages of the method can be used to dispose of abandoned stream.
