| 摘 要： | 老龄化垃圾渗滤液氨氮(NH3 -N)浓度极高，可生化性差，处理难度大。本研究采用物理化学和生物工艺相结合的方法处理老龄化垃圾渗滤液，动力波吹脱法去除NH3 -N，Fenton氧化法去除生物难降解化合物，A/O型SBR法去除生物可降解成分，创新性地提出了一种动力波吹脱-Fenton-SBR 组合工艺。通过对实验条件的正交分析，确定了最佳的实验参数。结果表明，经动力波吹脱-Fenton-SBR组合工艺处理处理后的垃圾渗滤液，其出水COD 和NH3 -N的去除率最高可达96.67%和97.98%。相比现有的诸多工程实例，本研究提出的组合工艺处理成本低至45.95 元/ t，处理效果更好，成本更低。

| Abstract: | Aging landfill leachate has extremely high ammonia-nitrogen (NH3-N) concentration, poor biodegradability and is difficult to process. Physicochemical and biological process were combined to treat aging landfill leachate. Dynamic wave stripping method was used to remove ammonia nitrogen, Fenton oxidation method was used to remove compounds that are not biodegradable, and finally A/O type SBR method was used to remove biodegradable components. A dynamic wave stripping-Fenton-SBR combined process was innovatively proposed. Through orthogonal analysis of experimental conditions, the best experimental parameters were determined. Results show that after dynamic wave stripping-Fenton-SBR combined process, the effluent COD and ammonia nitrogen removal rate can reach 96.67% and 97.98%. The cost of the combined process proposed is as low as 45.95 RMB/t, which has better treatment effect and lower cost compared with many existing engineering cases. |
