摘要：
采用厌氧/生物脱氮/MBR/NF/RO工艺处理含高浓度难降解有机物的垃圾渗滤液。运行结果表明, 该工艺对渗滤液的CODCr、BOD5、NH4+-N、TN的去除率均超过99%, 出水CODCr≤60 mg/L, BOD5≤20 mg/L, NH4+-N≤8 mg/L, TN≤20 mg/L, 达到《生活垃圾填埋场污染物控制标准》(GB 16889—2008)。

Abstract:
The combined process, anaerobic-biological denitrification-MBR-nanofiltration-reverse osmosis has been used for the treatment of highly-concentrated landfill leachate with refractory organic compounds. The operation results show that, the removing rates of CODCr, BOD5, NH4+-N and TN are over 99%. The effluent CODCr, BOD5, NH4+-N and TN are equal to or less than 60, 20, 8, 20 mg/L respectively, meeting the requirements specified in the Standard of Pollutant Control in the Domestic Rubbish Landfill Yard(GB 16889—2008).
