摘要
生物脱硫是最近二十年发展的脱硫新工艺。通过微生物菌群的作用,将硫化物氧化为单质硫并回收,与传统物理和化学法脱硫相比,生物脱硫有许多优点。本文概述了光合硫细菌和无色硫细菌的脱硫机理及影响因素,重点介绍了无色硫细菌脱硫的机理及影响因素,包括硫化物负荷及浓度、pH值、溶解氧及O2/S2-比等。同时介绍了THIOPAQ生物脱硫技术和Bio-FGD工艺。
Biological desulfurization was a new technique developed in two decades. In the process, sulfide was converted into sufur by microorgnasim community, and sulfur was recovered, by comparison with trditional method, the biological desulfurization offered many advantges. This paper introduced the mechanism and influence factors of desulfurization by photosynthetic sulfur bacteria and colourless sufur bacteria. And summarized the influence factors including sulfide loading rate、pH、sulfide concentration、oxygen concentration and consumption ratio between oxygen and sulfide. In addition, introduced THIOPAQ and Bio-FGD technology.
