厌氧氨氧化脱氮工艺研究进展

Research progress of anaerobic ammox denitrification process

在防止氮过量排放导致水体富营养化的同时,如何降低能耗和温室气体的排放成为当前污水脱氮急需解决的问题。文中综述了新型污水生物脱氮工艺—厌氧氨氧化(Anammox),重点介绍了厌氧氨氧化组合工艺的研究进展,指出了组合工艺在实际应用中的不足,并提出了解决工程应用缺陷的研究思路,并阐述了厌氧氨氧化反应在实际工程中的应用实例,并对厌氧氨氧化工艺的研究重点提出展望,为推广厌氧氨氧化工艺的大规模应用奠定基础。

How to save energy consumption and reduce greenhouse gas emission have become the issues that need to be solved urgently in current wastewater nitrogen removal while preventing excessive nitrogen discharge from causing eutrophication of water.This paper reviewed the new type of sewage biological denitrification process of anaerobic ammonia oxidation(Anammox), mainly introduced the research progress of combination of anaerobic ammonia oxidation process, pointed out the shortages of combination technology in the practical engineering application, and put forward the solution to engineering application defect, and expounded the application of anaerobic ammonia oxidation reaction in the actual engineering instances, prospected the research of anammox process and laid the foundation for the large-scale application of anammox process.
