The invention belongs to the technical field of waste gas treatment, in particular relates to a device and a method for removing sulfur-containing malodorous waste gas in petrochemical industry. Two rotary packing beds are arranged, alkaline liquid is introduced into the first rotary packing bed, and an electrolyte is introduced into the second rotary packing bed, so as to complete the two-stage absorption of malodorous waste gas in petroleum or chemical industry. The invention overcomes the shortcomings of the malodorous waste gas absorption device and method in the prior art, including high cost and incomplete absorption. The scheme of the invention has higher absorption efficiency to malodorous waste gas, can more completely absorb malodorous waste gas, and has less secondary pollution to environment.
