摘要
以宁波中心城区的某一马路为研究对象,分析该马路的某段有餐饮店的地表径流水质,以该马路无任何营业店面路段的降雨径流水样为对照。结果表明,沿街有小型餐饮店的地表径流中总氮(TN)、总磷(TP)、化学需氧量(COD)、总悬浮固体(TSS)等污染物的浓度均数倍于对照,尤其是降雨初期的径流水质。随着降雨历时的延续,各污染物浓度都呈逐渐下降趋势,并且两种径流水质基本接近。
The present paper discusses the effects of small catering business on the surface runoff quality taking such business along a certain road in the urban area of Ningbo as a case in point and with the same road without any restaurant as the control. Results show that the runoff from the road with catering business is polluted significantly with levels of TN, TP, COD, NH3-N and TSS, higher than those of the control runoff, especially during the early period of rainfall. As the rain lasts, the concentrations of pollutants all decrease and the quality of these two runoffs is almost the same.
