| 摘 要： | 通过对渗滤液经矿化垃圾回灌后水质特征的分析及现有除氨脱氮工艺用于渗滤液处理的可行性分析,提出了"多级低氧硝化反硝化+氨缺氧氧化"生物脱氮工艺流程,并阐述了其工艺的处理效果。得出结论:以渗滤液回灌处理出水作为研究对象,在不外加碳源条件下,该工艺可获得92%~99%的氨氮去除率,保证出水氨氮不高于25 mg/L,同时可获得73%~89%的总氮去除率。

| Abstract: | Based on the analysis on the characteristics of landfill leachate recharge and the feasibility of the existing leachate NH3-N removal process,the lower oxygen multi nitrification-denitrification and ammonia-anaerobic oxidation process is proposed and a detailed introduction to the effect is made further in the paper.It is shown that NH3-N removal rate of the treated recharged landfill leachate-is 92%～99%,NH3-N of effluent is decreased to 25mg/L,and removal rate of TN is 73%～89% without adding carbon source. |
