| 摘 要： | 在澳门半岛选取4个屋面汇水区,进行降雨屋面径流水样的收集与水质分析,监测项目包括:pH、浊度、TN、CODCr、TOC、Zn、Pb、Cu、Fe.研究结果表明,生锈铁皮屋的屋面径流水样中Zn平均浓度值超出国家地表水V类标准的2倍以上,TN和CODCr也超出地表水V类标准.屋面材料对屋面径流输出影响显著.从3场降雨事件不同屋面材料的径流水质参数的平均浓度值看,Zn和Pb的浓度排序:铁皮屋面(严重锈蚀)＞铁皮屋面(轻度锈蚀)＞铁皮屋(新油漆)＞混凝土.Pb浓度排序:铁皮屋面(严重锈蚀)＞铁皮屋面(轻度锈蚀)＞铁皮屋(新油漆)＞混凝土.而其它水质参数,如CODCr、TOC、TN,铁皮屋面的浓度值均大于混凝土.屋面径流排污规律和污染物浓度输出具有不确定性,且受降雨干期长度和降雨强度等因素的综合影响. |

| Abstract: | Four roof catchments in the city of Macao were selected for sampling and study. Water quality parameters such as pH, Turbidity, CODCr, SS, TN, Zn, Pb, Fe and Cu were analyzed. The results obtained show that the average Zinc concentrations in the roof runoff from the galvanized-iron roof is about 2 times of the class V of water quality standard China. Average TN and CODCr concentration also exceeds the criteria. Based on the water quality analysis from roof runoff in 3 rainfall events, the heavy metals including Zn and Pb are in the following order: galvanized-iron roof (rusted greatly) > galvanized-iron roof (rusted slightly)> galvanized-iron roof (new installed) > concrete roof. From the pollutographs analysis, the roof runoff discharge shows great uncertainties which depends on the length of dry weather period and storm intensity. |
| Keywords: | roof runoff galvanized-iron roof concrete roof Macau |
