Abstract According to the problems of methyl mercaptan (CH3SH) with foul odor, low odor threshold, wide range of sources and great harm to the human body and the environment, the research status of common technologies for the treatment of methyl mercaptan at home and abroad was reviewed. The emerging and popular treatment methods of methyl mercaptan-catalytic decomposition method, catalytic oxidation method, photocatalytic oxidation method and low temperature plasma method in recent years were mainly introduced, and the respective scope of application, the advantages and disadvantages were also pointed out. The results show that catalytic decomposition method, catalytic oxidation method and photocatalytic oxidation method have the advantages of high treatment efficiency, good adaptability and less product harm, but there are also shortcomings of poor catalyst activity and stability. The low-temperature plasma method is efficient and flexible, but it has disadvantages of low energy utilization efficiency and easy generation of toxic by-products. A single technology is difficult to achieve high-efficiency methyl mercaptan treatment effect with satisfying the economy at the same time. The coupling and synergistic use of multiple treatment processes and the in-depth study of the degradation mechanism are the research emphasis of methyl mercaptan treatment technology in the future.
