摘　　要：采用厌氧折流板反应器(ABR)对生活污水进行预处理试验研究,确定最佳水力停留时间HRT,并考察该工艺对生活污水中COD、SS、TN、NH4-N和TP的去除效果及其影响因素.研究结果表明:(1)最佳运行条件为HRT6h.(2)在最佳运行条件下,污水中CODCr、SS的去除率分别稳定在68.1%、88.3%左右,实现了较好的预处理效果;对生活污水中NH4-N、TN和TP的去除效果较差.The pretreatment of anaerobic baffled reactor （ABR） was conducted to treat the domestic sewage. The optimum hydraulic retention time （HRT） was determined, and the COD, SS, TN, NH4-N, TP removal efficiency and influencing factors of the process was in- vestigated. The research results showed that the optimum operation conditions of the process were HRT 6 h. Under the optimum conditions, the process presented perfect CODcr,SS re moval efficiency with about 75% and 88G of CODer and SS can be removed respectively. NH4-N, TN, TP removal efficiency of the process was unsatisfactory.
