摘要
Abstract
[Objective]The study aimed to investigate the membrane-bioreactor(MBR)for the effects on removing the COD and N-NH3 in the domestic sewage.[Method]With the water inlet from the second sewage treatment plant in Chengdu City as the pilot water,the membrane modules made with the hollow fiber membrane materials with high performance prepared by the independent development of PVDF was taken for the pilot study with the test technology of A/O-MBR,and the performance of MBR in the actual waste water was assessed.[Result]When the MBR was used for the sewage treatment,the average level of CODCr removal rate was more than 90%,and under the CODCr fluctuations in the water inlet was big,keeping the same hydraulic retention time all could make the CODCr in the water inlet maintain the stability at the lower level.MBR system had good effect on removing NH3-N,with the average Jevel of NH3-N being more than 90%.During the operation,the back flow amount maintained at 5 m3/h,the water outlet flow changed in 1.3-2.2 m3/h,the corresponding HRT changed in 6.7-12.0 h,but there was no greater change for the quality of the water outlet,indicating that the MBR system had no high requirements on HRT.[Conclusion] MBR system showed the good effects on removing the COD and N-NH3 in the domestic sewage.关键词
