Experimental Study On The Anaerobic-Aerobic Integrated Reactors Treating Ammonia-Nitrogen Organic Wastewater And Simultaneous Removal Of Sulfur By Denitrification

The basic reason of water eutrophication has been the existence of much nitrogen and phosphorus in water which yielded toxicity for human and biologic also. At the present time, the requirement of treating nitrogen and phosphorus in water pollution control engineering has been improved for water eutrophication. In order to satisfy the demand of effluent standard, denitrification ability by reforming traditional water treatment and exploiting kinds of new technology have been increased. So it has become to a hot research subject that developing and applying new-type and high efficient economical treating wastewater technology directing denitrification at present.Funded by the national 863 project named development and application of high efficient anaerobic and aerobic biological reactors, based on the previous experimental and engineering experiences of treating high concentration organic wastewater by anaerobic-aerobic fluidized bed of integrated reactor, this study applied the concept of short-distance nitrify to treat high concentration ammonia-nitrogen organic wastewater for denitrification. The purpose of this experiment was to find out the optimal experimental condition for this reactor by...
