| 摘要: | 以污泥基陶土组成填料柱模拟生物滞留设施, 研究其对径流削减、峰值滞后、污染物去除的效果, 并与普通陶粒和砾石填料柱进行对比. 结果表明, 在重现期分别为0.1, 1, 5, 10, 50a的降雨强度下, 污泥基陶土填料柱能有效削减径流量20%~80%, 滞后径流峰值出现时间8~40min, 削减峰值3.25%~12.9%, 明显优于陶粒和砾石填料柱. 重现期为1a时, 污泥基陶土填料柱比其他2组峰值出现时间滞后约25min, 径流量和峰值削减54%和6.25%; 水力负荷为0.5m3·m-2·d-1时, 在不同进水浓度下, 污泥基陶土填料柱的CODCr最大去除率比陶粒和砾石填料柱分别提高28%~44%和48%~65%; 对NH4+-N的处理效果与陶粒填料柱相差不大, 当进水浓度偏低时, 比砾石填料柱处理效果更佳. |
| Abstract: | Bioretention facility for runoff treatment is simulated by using filler column filled with sludge-based pottery clay (SBPC), commercial ceramsite and gravel to investigate their effects on runoff reduction, runoff peak lag and pollutants removal contrastively. The results suggest that: in different recurrence periods of torrential rain on 0.1, 1, 5, 10, 50a, SBPC column effectively reduce the runoff by 20%~80%, lagged the peak time of runoff for 8-40min, and reduce the peak value by 3.25%-12.9%, which is obviously better than that of commercial ceramsite and gravel filler column. In the recurrence interval of 1a, the outflow peak of SBPC column lags for about 25min in comparison to other two columns, and the runoff and the peak value decease by 54%, 6.25%, respectively. For the hydraulic load of 0.5m3·m-2·d-1, the removal capacity of CODCr on SBPC column at different inflow concentrations are found to be 28%-44% and 48%-65% higher than commercial ceramsite and gravel filler column, respectively. The removal of NH4+-N of SBPC column turns out to be similar to that of ceramsite filler column, but better than that of gravel filler column in low concentration inflow. |
