Simultaneous Removal of Carbonaceous and Nitrogenous Substances in Wastewater by a Continuous-Flow Fluidized-Bed Bioreactor

摘要: A continuous-flow fluidized-bed bioreactor system containing porous carrier particles was operated for simultaneous removal of carbonaceous and nitrogenous substances from wastewaster. The consisted two aerobic reactors in series with recycle-flow. Organic oxidation, ammonification urea nitrification took place both reactors, while denitrification concurrent those reactions occurred the reactor where artificial sewage recycled fluid were fed. In steady state, measurement microbial activities confirmed presence respective bacteria participating above reactions. These multiple proceeded simultaneously analyzed by a set simple reaction kinetics, which interpreted experimental results well.
