摘要
根据垃圾渗滤液有机污染物和含氮化合物浓度高的特点,采用"UASB+A/O+膜过滤"改进工艺处理垃圾渗滤液,结果表明,该处理工艺的处理效果稳定,UASB对COD的去除率达70%以上,A/O系统对氨氮的去除率达99%,膜过滤出水水质稳定达标,生化系统污泥产量低。出水水质满足《生活垃圾填埋场污染控制标准》(GB16889—2008)中"表2"要求。
According the feature of landfill leachate with high concertration of organic pollutants and nitrogen compounds, adoption improved technology of ＂UASB ＋ A/O ＋ Membrane filtration＂ treatment landfill leachate. The results show that, the effect of process is steady, the removal efficiency of COD above 70% by UASB, the removal efficiency of NH3-N is 99% by A/O, water quality can up to standard stably by membrane filtration ,the quality of sludge is little in processing system. The final effluent quality can steadily meet the claim of ＂ Table2 ＂ in （（ Standard for Pollution Control on the Landfill Site of Municipal Solid Waste）） （ GB 16889--2008 ）.
