摘要
硫酸盐型厌氧氨氧化(SRAO)可在厌氧条件下,将废水中氨和硫酸盐转化为氮气和低价态硫而同时去除,为污水脱氮除硫提供了新的思路,但对该反应的建立与反应器的启动还认识不清。该文综述了近年来的国内外SRAO脱氮研究进展,分析了SRAO反应的可能机理、微生物菌群以及反应发生的影响因素,提出了SRAO建立的一些关键问题,讨论了氨氮与硫酸盐可能的转化方式,可为今后研究探索方向。
Sulfate-reducing ammonia oxidation(SRAO)can convert ammonia and sulfate in wastewater into nitrogen and low-valence sulfur under anaerobic conditions and remove them at the same time,providing a new way for denitrification and desurfurization of wastewater,but it is not clear how to establish it.This article reviews the research progress in SRAO in recent years,analyzes the possible mechanism and the microbial community and the influencing factors of SRAO,puts forward some key issues in the establishment of SRAO,and discusses the possible transformation pathway of ammonia nitrogen and sulfate,for the purpose to point out the direction for future research.
