摘要
研究了高溶液悬浮固体浓度（MLSS）下流化床膜生物反应器污水处理的有关特性。实验结果表明，当MLSS为20～25g／L、填料填充率为59／6时，控制溶解氧（DO）为0．5～1．0mg／L、C／N为4～6、水力停留时间为4h，MBR工艺可实现很好的脱氮以及COD去除效果。在长期的实验中发现，此类型MBR在高MLSS有较好的耐冲击负荷能力、抗污染能力以及低污泥产率。
Study on the treatment characteristics of a novel MBR operated under high MLSS. The exerimenral results showed that it is feasible for this new novel MBR to put into application. If the MLSS was between 20～25g/L and suspended carrier in 5% volume rate, control DO between 0.5～1.0mg/L and C/N between 4～6 and HRT in 4h,the MBR can reach a high efficiency of treatment in denitrification and COD remove. In long term of operated , the novel MBR show high volumetric loading bearing and low membrane fouling and low sludge yields.
