Research on Flue Gas Denitrification Wastewater Purification Technology Based on Biological Denitrification
In the process of desulfurization and denitrification of flue gas,a large amount of high nitrogen and high salt wastewater is generated,and the total nitrogen content in the wastewater is high.Currently,purification technology has shortcomings such as long purification process,low efficiency,and poor purification effect.Based on this,a new oxygen denitration wastewater purification technology based on biological denitrification is proposed,with an anoxic aerobic aerobic three-stage biological filter as the core,achieving denitrification treatment of wastewater using salt tolerant microorganisms.According to practical applications,the average removal rate of nitrate nitrogen in water by this technology reached 93.7%,and the purification cost decreased by 74.6%compared to before optimization.
