| 摘 要： | 在监测天津市不同功能区(文教区和居住区)的平顶沥青屋面径流雨水水质的基础上,探讨了屋面径流雨水随降雨历时的变化规律及污染的影响因素.结果表明:平顶沥青屋面的初期径流雨水污染严重,CODCr、TOC、BOD5、TN、色度和浊度均超出地表水V类或生活杂用水标准,CODCr、BOD5和TN浓度的最高值可以达到1 632,399.814,55.01 mg/L,不宜直接收集回用.屋面径流雨水BOD5/CODCr为0.201,可生化性低.

| Abstract: | Based on the monitoring of the flat asphalt roof runoff quality of different functional areas, i.e. residential and education districts, in Tianjin, the variation of roof runoff quality during the rainfall and the factors behind the runoff pollution were discussed. The results showed that the pollution of early flat asphalt roof runoff was serious and the roof runoff could not be reused directly. The concentration of CODcr, TOC, BODs, TN, color and turbidity all exceeded the fifth level of the environmental quality standards for China or the miscellaneous water standards of living, and the highest concentration of CODcr, BOD5 and TN could reach 1 632, 399.814, 55.01 mg/L. With the average value of BODs/CODcr 0.201, the roof runoff rainwater had low biodegradability. |
