摘　　要：低碳氮比废水在深度脱氮方面面临碳源不足的问题,自养反硝化无需有机碳源,以低成本、污泥产量少的优势得到了广泛关注和研究。介绍了自养反硝化的原理及类型,综述了硫自养反硝化、铁自养反硝化及氢自养反硝化的最新进展,对其运行效果、优缺点及优势菌群做出了对比,展望了自养反硝化未来的发展方向,为今后实际工程应用提供参考。Low carbon nitrogen ratio wastewater is facing the problem of insufficient carbon source in deep denitrification.Autotrophic denitrification does not need organic carbon source, it has been widely concerned and studied because of its advantages of low cost and low sludge yield.Introduced the principle and types of autotrophic denitrification, summarizes the latest progress of sulfur autotrophic denitrification, iron autotrophic denitrification and hydrogen autotrophic denitrification, compares their operation effects, advantages, disadvantages and dominant flora, and looks forward to the future development direction of autotrophic denitrification, so as to provide reference for practical engineering application in the future.
