摘　　要：实验针对某大学学生食堂污水进行处理,采用由厌氧折流板反应器(ABR)和序批式活性污泥法反应器(SBR)组合工艺的处理系统。结果表明,在ABR流量为3 L/h(HRT=10.7 h),以及SBR曝气时间为10 h的条件下,系统处理效果最佳,对于进水流量为3 L/h,温度约为23℃,TN浓度为15 mg/L,TP浓度为2.9 mg/L以及COD为1 452 mg/L,系统出水TN、TP和COD去除效率分别达到93%、99%和99%。An experimental study was done to treat the dining hall wastewater in a university by anaerobic baffled reactor（ABR） and sequencing batch reactor（SBR）.The experimental results show that the system has the best treatment effect under a flow of 3 L/h（HRT equal to 10.7 hours） in the ABR and a 10 hour of aeration period in the SBR.In addition,the removal efficiency of TN,TP and COD reaches 93%,99% and 99%,respectively,when the flow rate is 3 L/h,the water temperature is about 23 ℃ and the wastewater contains 15 mg/L of TN,2.9 mg/L of TP and 1 452 mg/L of COD.
