摘　　要：分段式SBR是将传统SBR的曝气和沉淀过程在时间上进行分段．在不同段数厌氧／好氧／缺氧状态下交替运行。该试验以模拟生活污水为处理对象，在有效容积为12L的SBR反应器中进行了分段进水试验研究，结果表明：在15～30℃的温度范围内，当系统的水力停留时间为8h，污泥龄为15d时，COD，NH3-N，TN和TP的去除率分别可达88．9％，99．61％，78．9％和94．2l％，出水水质良好，无需另加碳源。The staged SBR is the process which divides aeration and sedimentation processes of conventional SBR into several stages in time. It is operated under the conditions of different stages of anaerobic/aerobic/anoxic alternation. The experiment mainly discussed the multi-stage SBR with useful volume of 12 L for nitrogen and phosphorus removal of simulative municipal wastewater in the temperature ranges from 15 ~C to 30 ~C. Tests revealed that under the condition of hydraulic retention time （HRT） of 8 hours and sludge retention time （SRT） of 15 days, the removal efficiency of COD, NH3-N, TN and TP can reach to 88.9 %, 99.61%, 78.9 % and 94.21%. The quality of effluent is good, and don＇t need to add carbon source into the experiment.
