两级UBF-两级BCOR工艺处理垃圾渗滤液启动研究

Start-up Research on Landfill Leachate Treatment Process of Two-stage UBF and Two-stage BCOR

采用两级UBF—两级BCOR工艺处理垃圾渗滤液,对工艺的启动情况进行了研究。试验结果表明:当水力负荷为0.42 h/L,启动时间为60 d时,出水COD平均去除率为67.4%,UBF工艺中出现甲烷八叠球菌,BCOR反应器的填料上已形成基本稳定的微生物种群,启动顺利完成。

Start-up of landfill leachate treatment process of two-stage UBF and two-stage BCOR was investigated. The results expatiated that when hydraulic load was 0.42 h/L and start-up time was 60d, average COD removal rate of effluent was 67.4%, methanococcus occurred in UBF reactor, stable microbe group formed on padding of BCOR reactor. By this time, the start-up was testified to have been completed smoothly.
