不同污水处理工艺N2O减排方法研究进展

摘要

The issue of nitrous oxide (N2O) as strong greenhouse gas from wastewater treatment process already attracted extensive attention.How to efficiently reduce N2O generation and at the same time keep high removal efficiency of pollutants is a challenge.This article reviewed the production mechanism,emission reduction methods and emission reduction amounts of N2O during the conventional nitrogen and phosphorus removal wastewater treatment processes and novel treatment processes of simultaneous nitrification denitrification,denitrifying phosphorus,anammox,etc.The beneficial references were provided for the related field researchers through the review of this article.%污水处理过程中产生强温室气体N2O的问题已经受到广泛关注,如何在保证处理效率的同时实现N2O有效减排成为水处理领域面临的重要问题.综述了传统生物脱氮除磷工艺和同步硝化反硝化、反硝化除磷、厌氧氨氧化等新型污水处理工艺运行过程中N2O的产生机理、减排方法和减排量,为相关领域的研究人员提供参考.
