本文利用分体式膜生物反应器（RMBR）处理了模拟废水。通过测定不同污泥负荷条件下，系统对有机物的去除效果，探讨了RMBR系统有机物降解动力学模型以及相关动力学参数。结果表明，在整个运行阶段系统中有机物的平均去除率为97.4 %，去除率较高。在0.22～0.27kgCOD/kgMLSS·d污泥负荷范围内，COD平均出水浓度满足了《城镇污水处理厂污染物排放标准》中的一级B标准（60 mg/L），而随着污泥负荷的不断增大，出水浓度超出了此标准。根据实验所得RMBR系统动力学参数Vmax为4.21 d-1，KS为688.74mgCOD/L，有机物降解动力学模型为[(So-Se)·Q]/(X·V)=4.21Se/(688.74+Se)。

n this thesis, the imitated wastewater was treated using the recirculated membrane bio-reactor (RMBR). Removal effect of the various treatment methods was studied by determiningorganic pollutants of wastewater at different sludge loading, and the organic pollutants degradation kinetics model and the corresponding kinetics’ parameter was discussed. The experimental result indicated that the average removal efficiency of the system in all phase is 97.4 %, which was a high level. In the conditions of 0.22～0.27kgCOD/kgMLSS·d sludge loading, the average effluent concentration was keeping with the B standard of level 1（60mg/L）of ‘Discharge standard of pollutants for municipal wastewater treatment plant’. But as the sludge loading increasing, the average effluent concentration went beyond the standard mentioned. According to the result of this experiment, the RMBR system kinetics parameter can be concluded that Vmax was 4.21d-1，KS was 688.74mgCOD/L, and the organic pollutants removal kinetics model was [(So-Se)·Q]/(X·V)=4.21Se/(688.74+Se).
