摘　　要：甲硫醇气味恶臭,嗅阈值低。针对甲硫醇分布于城镇污水厂各工艺区域,对污水厂周边环境及人体带来严重危害问题,探讨国内外对甲硫醇的生成机理研究、检测方法、治理技术。重点介绍了国内外针对城镇污水厂中甲硫醇的前沿治理技术和检测技术,并指出甲硫醇的去除伴随着硫化合物的参与,不同生物器适用于不同范围的甲硫醇治理。现阶段,单一的处理工艺较难满足高效的甲硫醇处理,应协同使用多种工艺,研究甲硫醇富集培养物的生长和代谢,进一步探究其降解机理。Methyl mercaptan(CH3SH)has a foul odor and low olfactory threshold.In view of the distribution of methyl mercaptan in various process areas of urban sewage plants,which brings the serious harm to the surrounding environment and human body,the formation mechanism,detection method and treatment technology of methyl mercaptan at home and abroad are studied.The advanced treatment and detection technologies for methyl mercaptan in urban sewage plants at home and abroad are introduced.It is pointed out that the removal of methyl mercaptan is accompanied by the participation of sulfur compounds.Different biological apparatus is suitable for the treatment of methyl mercaptan in different ranges.At the present stage,it is difficult for a single treatment process to satisfy the high efficiency methyl mercaptan treatment,so it is necessary to cooperate with a variety of processes to treat methyl mercaptan,further study the growth and metabolism of methymercaptan enriched cultures and explore the degradation mechanism.
