介绍了基于Yusuf Chisti-Murray Moo Young模型的含油废水MBR反应池的设计；研究了曝气量及反应器结构对膜间平均错流流速的影响，并据此选定MBR曝气量及反应器下降流过水断面积分别为200m3/h和3.9m2，获得的膜间平均错流流速为1.25m/s。一年半的工程实践表明膜组件的操作负压稳定在0.02MPa以下，远低于化学清洗时的操作负压控制标准0.05Mpa，从而解决了中空纤维膜应用于含油污水处理中膜污染严重的技术瓶颈，为处理其他难降解高浓度工业废水MBR的设计与应用提供了参考和依据。
介紹瞭基于Yusuf Chisti-Murray Moo Young模型的含油廢水MBR反應池的設計；研究瞭曝氣量及反應器結構對膜間平均錯流流速的影響，併據此選定MBR曝氣量及反應器下降流過水斷麵積分彆為200m3/h和3.9m2，穫得的膜間平均錯流流速為1.25m/s。一年半的工程實踐錶明膜組件的操作負壓穩定在0.02MPa以下，遠低于化學清洗時的操作負壓控製標準0.05Mpa，從而解決瞭中空纖維膜應用于含油汙水處理中膜汙染嚴重的技術瓶頸，為處理其他難降解高濃度工業廢水MBR的設計與應用提供瞭參攷和依據。

Based on the model summarized by Yusuf Chisti-Murray Moo Young,effects of aeration rate and MBR structure on cross-flow velocity along membrane surface were investigated. When the aeration rate and cross-sectional area were 200m3/h and 3.9m2 respectively,the cross-flow velocity in the MBR was 1.25m/s. Due to this higher cross-flow velocity, Transmembrane Pressure(TMP)of MBR was less than 0.02MPa throughout the one-year operation time.
