【摘要】 在折流板厌氧生物滤池(ABRF)下部增设污泥床,构成组合式折流板厌氧反应池(HABR)处理系统,用增加生物量的办法来提高系统的净化能力。中试结果表明,以HABR处理城镇污水,若容积负荷控制在1～2kgCOD (m3·d),COD去除率可达70%～80%,出水COD和SS的浓度可达到《污水综合排放标准》(GB8978—1996)的二级标准。更多还原

【Abstract】 Combination type baffle plate anaerobic reactor (HABR) treatment system was composed by addition of sludge bed in downstream of baffle plate anaerobic biofilter (ABRF),so as to improve the purification capacity of the system by increasing biomass.The pilot test result showed that when the volume and load of HABR are controlled at 1～2 kgCOD/(m~3·d) in treatment of municipal wastewater,COD removal can come up to 70%～80%,and effluent COD and SS concentration can achieve II-grade criteria specified in <Integrated Wastewater Discharge Standard>(GB 8978—1996).更多还原
