摘　　要：大部分工业生产都面临着高氮、高矿化工业废水的难题。脱氮处理过程效率较低,且耗费资源。本文介绍了生物法、膜法、气相法、氧化还原法以及其他脱氮技术的原理、影响因素和缺点,突出高脱氮率,低成本脱氮的必要性。总结不同脱氮方法的脱氮效率,经济性,并论述了当前工业脱氮研究现状及发展趋势。为响应减污降碳、节能减排的号召,将国内外现有脱氮手段与绿色能源相结合,以期为含氮工业废水的脱氮工艺进一步开发与应用提供参考。The treatment of high-nitrogen wastewater has always been a challenging issue in most industrial production processes. The denitrification process exhibits low efficiency and consumes resources. This paper provides an overview of the principles, influencing factors, and drawbacks of denitrification technologies including biological methods, membrane methods, gas-phase methods, redox methods, and other techniques, emphasizing the necessity of achieving high denitrification rates and low-cost denitrification. The denitrification efficiencies of different methods under identical conditions are summarized, and the current research status and development trends in industrial denitrification are discussed. In response to the call for pollution reduction, carbon reduction, energy saving, and emission reduction, the integration of existing denitrification methods from both domestic and international sources with green energy is proposed, aiming to provide a reference for further development and application of denitrification processes for nitrogen-containing industrial wastewater.
