摘要
利用厌氧UASB+膜生物反应器MBR+纳滤工艺处理垃圾填埋场产生的垃圾渗滤液,介绍了各处理阶段的设计、运行参数和经济技术指标,设计处理规模为100 m3/d。在进水ρ(COD)为10 000 mg/L,ρ(BOD5)为5 000 mg/L,经处理后,出水ρ(COD)达到60 mg/L,ρ(BOD5)约为20 mg/L,去除率分别达到99.4%、99.6%,且出水稳定,达到地方标准DB 11/307-2005《北京市水污染排放标准》中二级排放标准。
Treatment of landfill leachate by the combined system of UASB（upflow anaerobic sludge blanket）,MBR（membrane bioreactor） and NF（nanofiltration） was tested.The design and operation parameters and economic-technical indexes were investigated by an engineering example with the sewage treating capacity of 100 m3 /d.During the experiment,the effluent concentration of COD and BOD5 could attain 60 mg /L and 20 mg /L,the removal rates of COD,BOD5 achieved 99.4% and 99.6% respectively when the influent concentration of COD,BOD5 were 10 000 mg /L and 5 000 mg /L.Results showed that the treatment technology ensured ideal effluent effect,and the effluent quality reached secondary discharge standard specified by＂Water Pollutants Discharge Standard in Beijing＂（DB11 / 307-2005）.
