The invention provides a sulfur monochloride hydrolysis harmless treatment method which comprises the following steps: S1, introducing sulfur monochloride into a reaction tank added with water to obtain sulfur, hydrochloric acid, hydrogen chloride and sulfur dioxide; s2, introducing the obtained hydrogen chloride and sulfur dioxide into a primary absorption bottle added with water to obtain crude hydrochloric acid; s3, hydrogen chloride and sulfur dioxide which do not participate in the reaction in the first-stage absorption bottle sequentially pass through a second-stage absorption bottle and a third-stage absorption bottle and are introduced into a fourth-stage absorption bottle added with a sodium hydroxide solution, and a sodium sulfite solution is obtained. In the process of hydrolyzing the sulfur monochloride, tail gas generated in the treatment process can be fully absorbed, and the aim of harmless treatment of hydrolysis of the sulfur monochloride is achieved. 本发明提供了一种一氯化硫水解无害化处理方法，其包括步骤，S1.将一氯化硫通入加有水
