摘要
介绍了北京安定卫生填埋场采用A2/O-MBR+NF+RO组合渗沥液处理工艺对CODCr、氨氮和电导率的平均去除率分别为99.55%、99.15%、93.97%,出水水质达到GB 16889—2008的排放要求,运行费用仅为22.88元/t,经济效益和环境效益较好;并指出实际运行过程中应注意的问题。
The leachate treatment process of A2/O-MBR＋NF＋RO was used in Beijng Anding Waste Sanitary Landfill Site. In actual operation of the combination process, the average removal rates of CODc, ammonia nitrogen and conductivity were 99. 55%, 99. 15% and 93. 97% respectively, and the effluent quality could meet the standard of GB 16889--2008. The operation cost was 22. 88 yuan por ton. The process has good economic and environmental benefits. And the matters needing attention during operation were pointed out.
