摘　　要：在对烟气进行脱硫脱硝处理的过程中会产生大量的高氮、高盐污水,污水中的总氮含量较高,目前净化处理技术存在着净化工艺流程长、效率低、净化效果差不足。基于此,提出了一种新的基于生物脱氮的氧气脱硝污水净化处理技术,以缺氧-好氧-好氧三段式生物滤池为核心,实现了利用耐盐微生物对污水的反硝化处理。实际应用表明,该技术对水中硝酸盐氮的平均祛除率达到了93.7%,净化费用比优化前降低了74.6%。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.
