摘要
硫酸盐型厌氧氨氧化(Sulfate-reducin ammonia oxidationg,SRAO)是一类可以直接利用废水中氨氮和硫酸盐生成氮气和低价态硫元素的同步脱氮除硫反应,但此类反应的功能菌尚未完全明确且影响因素众多。综述了SRAO启动的影响因素,并且列举了目前已成功启动并稳定运行的SRAO反应器,可参考其影响因素通过严控反应条件达到快速启动SRAO的目的,讨论了利用数学模型对SRAO过程进行模拟,可对SRAO未来的发展及工程应用有所帮助。
Sulfate-reducing Ammonia Oxidation(SRAO)is a simultaneous nitrogen and sulfur removal reaction that can directly utilize ammonia and sulfate in wastewater to generate nitrogen and lower-valent sulfur elements.This paper reviews the factors influencing the start-up of SRAO and lists the SRAO reactors that have been successfully started up and operated stably,which can be used to achieve rapid start-up of SRAO by strictly controlling the reaction conditions with reference to their influencing factors,and discusses the use of mathematical models to simulate the SRAO process,which can be helpful for the future development and engineering applications of SRAO.
