摘要
为探究水位和降雨对河涌水质的影响,以佛山市五福围片区作为研究区域,建立SWMM水动力-水质模型,模拟分析感潮河段在降雨和水位影响下水质的变化规律。模拟结果显示:水位和降雨对河涌水质有着明显的影响。晴天时,闸站向河涌补水使河涌水位升高,从而水质提升;而随着降雨量增加时,冲刷作用导致水质恶化,但降雨径流平均浓度降低,暴雨时降雨径流平均浓度反而升高;在4条重点河涌中,北合围涌排放入河径流量和污染物负荷排放最高,而冲元涌最低。研究结果对于佛山市五福围片区的河涌水质管理和治理具有一定的启示作用。
To investigate the influence of water level and rainfall on water quality of river inwelling,this paper builds a hydrodynamic and water quality model based on SWMM in Wufuwei District of Foshan City to simulate the variation law of water quality in tidal reach under the influence of rainfall and water level.The simulation results show that the water level and rainfall have obvious influence on the water quality of the river.On sunny days,the water level of the sluice station rises and the water quality improves.With the increase in rainfall,the water quality deteriorates due to erosion,but the average concentration of rainfall runoff decreases,while the average concentration of rainfall runoff increases during heavy rainfall.In the four major streams,the discharge of runoff and pollutant load from Beihewei Stream is the highest,while Chongyuan Stream is the lowest.The results have some implications for the management and treatment of river swelling water quality in Wufuwei District of Foshan City.
