| 摘 要： | 以受污染的城市河道新运粮河为对象,开展了微曝气生物滤池(BAF)-多级土壤渗滤系统(MSL)工艺的河道旁路示范工程研究。结果表明,BAF-MSL工艺对TN的去除效果明显,TN去除率达到了87.56%,TN水质指标能够满足地表水V类水质标准要求。BAF段和MSL段分别较好地完成了硝化和反硝化过程,其中新型固相碳源的加入保障了MSL系统的持续高效的反硝化能力。工艺工程对TP和有机物也具有一定的去除能力,去除率分别达到了57.69%和35.99%。新型固相碳源的加入为反硝化过程提供了充足的碳源,增强了MSL系统的脱氮能力。

| Abstract: | A combined process of biological aerated filter (BAF) with multi-soil-layering (MSL) system was designed as a demonstration for enhanced nitrogen removal from Xin Yunliang River bypass.Results indicated that such a process combination could achieve effective nitrification in the BAF and continuous denitrification in the MSL.Nitrogen removal as TN was attained to 87.56% and effluent quality in terms of TN could meet the Class V limits of Environmental Quality Standards for Surface Water.TP and organic matter removal rates were 47.80% and 35.99%,respectively.Application of novel biodegradable polymers (BDPs) provided sufficient carbon source for denitrification process,enhancing the capacity of nitrogen removal in MSL. |
