含硫恶臭气体处理方法的研究进展

Research Progress in Treatment Methods of Sulfur-containing Odor Gas

含硫恶臭气体因其嗅觉阈值低、涉及的行业广泛、毒性大而备受关注。主要的代表物为硫化氢、二硫化碳、硫醇、硫醚等。介绍了含硫恶臭气体的常规处理方法,如物理法,燃烧法、吸收法、吸附法等化学方法,还有近年来发展较快的光催化氧化技术、等离子体技术、生物脱臭技术、无极紫外辐射技术等新兴处理技术。对各种处理方法和技术的未来发展趋势进行了展望。

Sulfur-containing odor gas has been paid close attention because of its low threshold of smell and toxicity.The main representative includes hydrogen sulfide,carbon disulfide,mercaptan,thioether and so on.In this paper,routine treatment methods of sulfur-containing odor gas were introduced in details,including physical methods and chemical methods.Some new treatment methods were also discussed,such as photocatalytic oxidation,plasma technology,biological deodorization and electrodeless ultraviolet technology.At last,developing tendency of all treatment methods was put forward.
