摘　　要：针对一种一体化膜生物膜反应器,进行了以间歇方式运行处理农村生活污水的试验研究。结果表明,采用微滤膜出水,该处理方式抗冲击负荷能力强,且可实现自动化运行;当厌氧反应时长1.5 h、好氧曝气及出水时间共4 h、好氧阶段溶解氧3～4 mg/L、充水比0.33时,反应器中CODcr、氨氮、总氮、总磷、浊度的出水平均值分别为38.00 mg/L、2.82 mg/L、10.50 mg/L、0.39 mg/L和1.55NTU,平均去除率分别为79.1%、83.5%、58.0%、81.3%和98.6%;反应器中形成大量高端营养级水平微生物种群,食物链长且相互交叉,呈明显的网状结构(食物网),能保证系统稳定的污水处理效果及较强的抗冲击负荷能力。An integrated membrane biofilm reactor was applied to intermittently treat rural domestic wastewater.The results suggested that the method that adopted the millipore filtration had strong impact resistance on load copacities,and could be highly automated operation;under the conditions of anaerobic treatment for 1.5 h,aeration and discharge treatment for 4 h,DO in reactor 3～4 mg/L and fill ratio 0.33,the average values of CODcr,NH3-N,TN,TP and turbidity in effluent were 38.00 mg/L,2.82 mg/L,10.50 mg/L,0.39 mg/L and 1.55 NTU,respectively;and the average removal rates were 79.1%,83.5%,58.0%,81.3% and 98.6%,respectively.The reactor formed lots of microbial populations in high trophic level,the food chain was long and overlapped that presented a network structure,it guaranteed the stable treatmeat effects and strong impact resistance on load capacities.
