摘　　要：采用移动床生物膜反应器-生物滤池(MBBR-BF)一体化污水处理设备进行实际污水中试试验,考察曝气量对一体化设备挂膜启动阶段污染物去除效果的影响,探究低温环境下一体化设备适应性及污染物处理能力。结果表明:曝气量降低对COD和TN去除率影响较小,而NH_(3)-N与TP的去除率随之下降,NH_(3)-N平均去除率由87.46%降至48.64%,TP平均去除率由72.41%降至54.66%;常温环境下COD、NH_(3)-N、TN、TP平均去除率分别为92.48%、94.41%、49.39%和61.63%,低温环境运行对污染物去除效果有明显影响。中试应用试验状况良好,一体化设备在冬季低温环境下运行状况正常,可为农村生活污水的有效处理提供重要参考。We carried out the pilot-scale experiment to investigate the effect of aeration rate on the pollutants removal in the start-up stage of membrane-forming process in an integrated wastewater treatment plant with moving bed biofilm reactorbiofilter(MBBR-BF)and explored the adaptability of integrated equipment and pollutant treatment capacity in low temperature environment.The results show that the decrease of aeration rate has little effect on the removal rate of COD and TN,while the removal rate of NH_(3)-N and TP decreased accordingly,the average removal rate of NH_(3)-N decreased from 87.46%to 48.64%,and the average removal rate of TP decreased from 72.41%to 54.66%.Under normal temperature environment,the average removal rate of COD,NH_(3)-N,TN,and TP are 92.48%,94.41%,49.39%,and 61.63%,respectively.Low temperature has a significant impact on the pollutants removal.The pilot-scale application experiment is in good status and the integrated device works satisfactorily in winter low-temperature environment.Our study can provide an important reference for the effective treatment of rural domestic wastewater.
