摘要:
针对目前合流制溢流(CSO)污染严重的问题，开展了生物滤池/生物滞留池组合设施去除CSO污染物的研究。首先探讨了砾石、火山岩、陶粒、沸石等4种生物滤池填料对N、P的吸附和解吸附特性，然后通过模拟柱试验分析了含不同填料的生物滤池对CSO污染物的去除效果。结果显示，火山岩填料对CSO污染物的去除效果最佳。在此基础上，将火山岩填料生物滤池与改良介质填料生物滞留池组合起来，探究不同水力负荷和不同污染负荷下组合设施对CSO污染物的去除效果。结果表明，当水力负荷较低时组合设施对CSO污染物的去除效果较好，而当水力负荷较高时组合设施对TN和COD的去除效果不稳定；不同污染负荷下组合设施对CSO污染物均具有较好的去除效果。
Abstract:
The removal of pollutants in the combined sewer overflow (CSO) by a combined process of biofilter and bioretention pond was investigated to solve this serious pollution problem. Firstly, the N and P adsorption and desorption characteristics of four kinds of biofilter media (gravel, volcanic rock, ceramsite and zeolite) were discussed. Then, the removal performance of the CSO pollutants in the biofilter containing different media was analyzed by simulated column experiments. The volcanic rock medium had the best removal effect on the CSO pollutants. On this basis, the biofilter with medium of the volcanic rock and the biofilter with the modified medium were combined to explore the removal performance of the CSO pollutants under different hydraulic loads and different pollution loads. The combined process had a better removal effect on the CSO pollutions when the hydraulic loads were low, while the facility had an unstable removal effect on the TN and COD when the hydraulic load was high. The combined process had a good removal effect on the CSO pollutants under different pollution loads.
