摘要
作为一种绿色、经济的新兴技术,生物脱硫技术正逐渐受到人们的青睐。然而,处理气体中的有机硫对生物脱硫过程的抑制是一个不容忽视的问题。文中总结了近年来国际上对生物脱硫过程中有机硫影响的相关研究,主要包括有机硫的种类及理化特征、有机硫对脱硫过程的影响、有机硫的作用机理、操作条件与有机硫的相互关系以及耐受有机硫微生物的种类,并据此归纳了缓解有机硫对脱硫过程影响的一些方法,为生物脱硫工艺在实际应用中稳定、高效地运行提供一定的指导。
As a green and economic emerging technology,biological desulfurization is popular.However,biological desulfurization is inhibited by organosulfur in the treatment gases which cannot be ignored.This article summarizes relevant studies on the influence of organosulfur on biological desulfurization in recent years,including the types and physicochemical characteristics of organosulfur,the influence of organosulfur on the desulfurization process,the reaction mechanism of organosulfur,the interplay between organosulfur and some operating conditions,and species of microorganisms that are tolerant to organosulfur.Methods for mitigating the effect of organosulfur on the desulfurization process are discussed,to provide references for the stable and efficient operation of biological desulfurization.
