高负荷条件下膜反应器污水处理实验研究

Research of the integrated floating carrier-biofilm membrane bioreactor

总结分析了在各种负荷条件下悬浮载体生物膜型反应器的试验结果。研究表明:悬浮生物膜反应器MBR应用于污水处理是完全可行的,它具有有机负荷高、处理效果优、耐冲击负荷能力强、占地面积少等优点;在悬浮填料投加率为30%时,对于CODCr≤2500mg/L的废水处理效果可达到废水回用标准。

A new type of membrane bioreactor （MBR）, in which the microfiher membrane （MF） is coupled with the floatingbiofilm carrier, has been developed and researched. The experimental results show that it is feasible for this new integrated biofilm MBR to put into application. This new MBR is characteristics of high organic loading, excellent effluent quality, stability to shocking loading and small footprints. Under the conditions of the influent CODcr 〈 2 500 mg/L, 30% biofilm media volume rate, the effluent quality can reach the standards of the wastewater reuse.
