Abstract
This paper briefly discusses the source, harm and removal methods of sulfur-containing malodorous gas. At this stage, the main methods for treating sulphur-containing malodorous gases are physical, chemical and biological methods. In contrast, low temperature plasma technology combines the advantages of physical, chemical and biological methods, and can effectively overcome the disadvantages of traditional processes. Through the comparison of various methods, the advantages of low temperature plasma treatment of sulfur-containing malodorous gas are summarized, and the corresponding removal mechanism is proposed. The treatment progress and existing problems of using low-temperature plasma to remove sulfur-containing malodorous gas, especially hydrogen sulfide, carbon disulfide, methyl sulfide, methyl mercaptan and dimethyl disulfide, are comprehensively discussed. A new idea for the simultaneous removal of multi-component sulfur-containing malodorous gas by low temperature plasma is proposed. Compared with traditional methods, low temperature plasma technology has the advantages of simple process, strong applicability, easy operation, and low energy consumption in processing sulfur-containing malodorous gases. The treatment of sulfur-containing malodorous gas by low-temperature plasma technology needs further research.
Highlights
The direct emission of malodorous gas will endanger human health, and pose a serious threat to the surrounding environment
It was found that voltage relative to residence time and initial concentration had the greatest effect on the decomposition efficiency of methyl mercaptan
Low temperature plasma technology has the advantages of simple process, strong applicability, easy operation, and low energy consumption in processing sulfur-containing malodorous gases
Summary
The direct emission of malodorous gas will endanger human health, and pose a serious threat to the surrounding environment It is mainly through the odor group such as sulfur, carbonyl group to stimulate olfactory cells[1,2]. The olfactory threshold of human smell for most malodorous substances is below 10-9, which far exceeds the minimum detection concentration of malodorous substances by analytical instruments and the allowable emission concentration of the factory. Low temperature plasma technology combines the advantages of physical, chemical and biological methods, and can effectively overcome the disadvantages of traditional processes
