摘　　要：垃圾渗滤液和厨余垃圾处理厂的沼液,含有极高浓度氨氮、总氮和有机污染物,采用常规硝化反硝化工艺,它们能耗高、碳源投加量大,运行成本居高不下。在脱氨技术日趋成熟的前提下,渗滤液(沼液)首先采用AB工艺的A段,去除绝大部分COD和SS,然后进行脱氨处理去除大部分氨氮,再进入生化处理系统。新AB工艺的应用处理效果更佳,可以大幅降低运行成本,实现低碳排放,在填埋场渗滤液、焚烧厂渗滤液、厨余厂沼液和垃圾转运站污水处理领域具有极高的应用价值。Landfill leachate and biogas slurry from kitchen waste treatment plants contain extremely high concentrations of ammonia nitrogen, total nitrogen and organic pollutants. Conventional nitrification and denitrification process has high energy consumption, large amount of carbon source and high operating cost. Under the premise of the increasingly mature deamination technology, the leachate(biogas slurry) firstly adopts the A stage of AB process to remove most of COD and SS, and then carries out deamination treatment to remove most of ammonia nitrogen, and then enters the biochemical treatment system. The application and treatment effect of the new AB process is better, which can significantly reduce operating costs and achieve low carbon emissions. It has high application value in landfill leachate, incineration plant leachate, biogas slurry of kitchen waste plant and waste transfer station sewage treatment.
