摘　　要：将好氧移动床工艺与动态膜生物反应相结合,用于处理高氨氮、低碳/氮废水,试验结果表明,反应器具有良好的处理效果,在整个试验期间,出水COD、氨氮和浊度分别在50 mg/L、50 mg/L和8 NTU以下,反应器对COD、氨氮和浊度的平均去除率分别为80%、75%和80%。同时,本次试验还对系统的稳定性进行了研究,结果表明,好氧移动床动态膜生物反应器具有很好的抗流量冲击和有机物浓度冲击的能力;而且低温(10℃左右)和水力停留时间(13～18 h之间波动)对系统的影响不明显。Aerobic Moving bed was combined with dynamic membrane reactor to dispose the wastewater with high concentration nitrogen and low C/N ratio. Results indicated that the dynamic membrane-moving bed biofilm reactor （M-MBBR） had good ability of disposing wastewater. During this test, M-MBBR obtained the average COD removal rate of 80 %, nitrogen removal rate of 75 %, turbidity removal rate of 80 %. Moreover, the stability of the M-MBBR system was investigated. It was found that M-MBBR had good anti-shockloading abilities of flow and organic matter concentration. Furthermore, the effluent of M-MBBR could not be influenced by low temperature （about 10℃） and the change of hydraulic retention time （in the range of 13-18 h）.
