硫酸盐还原氨氧化反应研究进展

摘要

Sulfate-reducing ammonia oxidation (SRAO) could simultaneously remove ammonium and sulfate in one anaerobic reactor,providing a new idea on simultaneous biological denitrification and desurfurization of wastewater. Research progress in SRAO in recent years both in China and abroad is summarized ,mainly including the simultane-ous transformation characteristics of ammonium and sulfate,reaction equation of SRAO,microbial community in sludge,and the influencing factors of SRAO reaction. Furthermore,the directions of SRAO as well as the challenges faced in application are put forward.%硫酸盐还原氨氧化（SRAO）反应可以在1个厌氧反应器中实现氨和硫酸盐的同步去除，为废水同步生物脱氮除硫提供了新思路。综述了SRAO反应近年来的国内外研究进展，主要包括SRAO反应的氨和硫酸盐同步转化特性、反应方程式、污泥中微生物菌群以及反应的影响因素，并指出了SRAO反应的未来研究方向以及该反应走上实际应用面临的挑战。
