Abstract: 自行设计的双反应器MUCT-MBR简化了MUCT工艺,将反应池由5个简化到2个,减小了工艺占地面积,并且采用膜过滤取代二沉池出水,操作简单,出水安全可靠.针对MUCT-MBR工艺脱氮除磷性能,尤其是反硝化除磷功能进行研究.结果表明,当进水C/N/P比在33.3/5/1～25/5.5/1范围内,整个实验过程中COD、TN和TP平均去除率分别达到89.3%、75.4%、79.2%;且膜出水不受污泥沉降性的影响.缺氧段的反硝化吸磷是MUCT-MBR工艺除磷的关键,系统运行至第58 d,系统中反硝化除磷菌(DPAOs)所占比例达84.2%,反硝化除磷占系统总磷去除的67.07%.
