摘要
采用ABR-SBR工艺处理生活污水,考察了影响反应器处理效果的因素和工艺对污染物的去除效果。结果表明:在ABR水力停留时间为12h,SBR厌氧时间为2h、曝气时间为3.5h的情况下,ABR-SBR工艺处理生活污水,出水COD和SS达到城镇污水处理厂污染物排放标准(GB18918-2002)中一级A标准,出水的氨氮、TN和TP均优于GB18918-2002的一级B标准。
Anaerobic baffled reactor（ABR）followed by sequencing batch reactor（SBR）was used to treat domestic sewage.The influencing factors of treatment effect and the removal efficiency of pollutants are investigated.The experimental results show that the concentration of COD and SS in effluent meet the first level A criteria,and concentration of NH＋4-N.TN and TP in effluent are superior to the first level B criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB18918-2002） under the following conditions： HRT of 12 h in ABR,anaerobic time of 2 h and aeration time of 3.5 h in SBR.
