Shortcut Nitrogen Removal Process and System by using Partial Nitritation in SBBR(Sequencing Batch Biofilm Reactor) with Media

摘要

Initiate a nitrogen removal device in sewage and wastewater. According to one aspect of this embodiment, a pre-treatment unit for removing solids or organic matter in the incoming sewage and wastewater, a sludge treatment unit for receiving the solid material removed from the pre-treatment unit, concentrating and digesting the inflow to separate the dehydrated cake and desorbing liquid, and the pre-treatment unit A batch-type biofilm reactor that receives rough sewage and wastewater and adjusts the ratio of ammonia nitrogen and nitrite nitrogen in the sewage and wastewater to a preset ratio, and a batch-type biofilm reactor that receives sewage and wastewater that has passed through the batch biofilm reactor and receives ammonia nitrogen in sewage and wastewater And control the anammox reactor and the batch-type biofilm reactor that removes nitrite nitrogen with nitrogen gas, and if it is set in advance, so that the leaching liquid separated from the sludge treatment unit is introduced into the batch-type biofilm reactor rather than the sewage and wastewater that has passed through the pretreatment unit It provides a nitrogen removal device in sewage and wastewater, characterized in that it comprises a control unit for controlling.
