摘要：

A new moving bed biofilm reactor (MBBR) has been developed in Norway. The biomass is attached to carrier elements that move freely along with the water in the reactor. It has been demonstrated that existing, high loaded, activated sludge plants can easily be upgraded to nitrogen removing MBBR plants. With chemically enhanced mechanical treatment, full scale tests showed that 80-90% total nitrogen could be removed in a MBBR plant at a total empty bed hydraulic retention time (HRT) of 2.6 hours. The plant was operated in the post-denitrification mode, using methanol as an external carbon source.
