采用UASB+MBR+DTRO处理低负荷生活垃圾渗滤液的研究

Study on UASB + MBR +DTRO Treatment of Low Load Landfill Leachate

对低负荷运行状态下某生活垃圾渗滤液处理厂监测的数据进行分析,研究UASB、MBR、DTRO各工艺单元及工艺系统对渗滤液中COD_(cr)、SS、NH_(3)-N等污染物质的去除效果及去除率,分析UASB+MBR+DTRO工艺对渗滤液的处理效果。经过11个月的长时间运行监测,处理后出水水质能稳定达到《城市杂用水水质标准》(GB/T18920-2002)城市绿化水水质标准。

By analyzing the monitoring data of a MSW leach treatment plant under the condition of low load operation, the removal efficiency and removal rate of CODcr, SS, NH;-N and other pollutants in leach by UASB,MBR and DTRO process units and process systems were studied, and the treatment effect of UASB+MBR+DTRO process on leach was analyzed.After 11 months of long-term operation monitoring, the effluent quality of the treatment plant has reached the urban green water quality standard of "Urban Miscellaneous Water Quality Standard"(GB/T 18920-2002).
