摘　　要：以厌氧消化污泥作为厌氧折流板反应器ABR的接种污泥,研究恒温(35℃)条件下ABR处理生活污水的启动和运行特性.实验结果表明,ABR反应器仅用了39 d就完成初次启动,COD去除率一直稳定在60%左右.在以后运行的5个阶段里,即当水力停留时间为4～10 h,容积负荷为1.17～2.9 kg COD/m3·d,反应器对COD的平均去除率基本稳定在70.49%～80.2%;并且当HRT=7 h,VRL=1.612 kg COD/m3·d时,反应器对COD的去除率平均高达80.2%,平均C0D出水低于100 mg/L.在实验过程中(除启动阶段外),反应器出水碱度均远远大于进水碱度,VFA均在1.5 mmol/L以下.The performance of anaerobic baffled reactor（ABR） treating domestic wastewater at 35℃ was investigated in this study. The result of the experiment is below： the process of starting-up of ABR was only 39 days and the removal of COD was kept about 60% ; when hydraulic retention time （HRT） were 4 ～ 10 h, volume rate loading （VRL） were equal to 1.17 ～2.9 kg COD/m^3 ·d, the average COD removal rates were 70.49% ～80.2%. When HRT was 7 h, VRL was 1.612 kg COD/m^3· d, the average removal of COD is 80.2% and the average was less than 100 mg/L; the alkalinity effluent was higher than that of influent water and the concentration of voltaic fatty acid （VFA） was below 1.5 mmol/L during the running process of ABR except the start-up phase.
