Method for processing malodorous gas and device thereof

The invention discloses a method for processing malodorous gas and a device thereof. Malodorous gas is introduced from a gas inlet at the bottom of a deodorization tower through a gas collecting device, an oxidizing agent is introduced from an oxidizing agent inlet at the top of the deodorization tower through an oxidizing agent supplying device simultaneously, and the malodorous gas and the oxidizing agent are contacted and reacted at a main body portion of the deodorization tower. Gas after reaction is discharged through a gas outlet, and the oxidizing agent after reaction is collected at the bottom of the deodorization tower and is introduced into an exhaust liquid processing device through an oxidizing agent outlet. By means of the method, the deodorization efficiency is high, the processed gas can reach second-level emission standards allowed by the state, and the method can be used for processing waste gas in the chemical industries.
