摘　　要：考察了膜生物反应器处理洗浴废水时 ,污泥浓度对出水水质及膜通量的影响。结果表明 ,尽管试验中污泥沉降性能较差 ,但当污泥浓度大于 2 30 0mg/L时 ,出水仍能达到《城市污水再生利用　城市杂用水水质标准》(GB/T1892 0 -2 0 0 2 ) ;出水COD随污泥浓度升高而降低 ;膜通量与污泥浓度的对数值呈线性关系。由于处理效果和膜通量两方面的因素 ,对于本试验中的原水 ,MLSS的适宜范围为 2 30 0～ 5 0 0 0mg/L。A study on influences of MLSS on effluent and membrane flux was carried out with membrane bjloreactor(MBR)in treating bathing wastewate.The results showed that in spite of the bad sludge sedimentation performance,the effluent reached the standard of GB/T1 8920-2002《Urban Wastewater Reclamation Mixed Water Used for Living of China》when MLSS was over 2300mg/L.The COD of effluent descended along with the increase of MLSS.Membrane flux and the logarithm ofMLSS had linearity relations.The optimum MLSS was 2300～5000mg/L according to removal efficiency and membrane flux.
