The invention provides a method for treating sulfur removal sweeping tail gas in the shutdown process of a sulfur recovery device. The method comprises the following steps: sending the sulfur removal sweeping tail gas which is led out of a Claus unit into a hydrogenation reactor of a Claus tail gas hydrogenation and absorption unit, and enabling the tail gas to be in contact with hydrogen and a hydrogenation reduction catalyst under hydrogenation reduction conditions to obtain gas after hydrogenation reduction, wherein the hydrogenation reduction conditions are controlled to enable sulfur in the gas after hydrogenation reduction to completely exist in the form of hydrogen sulfide. The method provided by the invention has great industrial application value and can be widely used in sulfur recovery methods in the field of petrochemical industry, coal chemical industry and natural gas treatment.
