Integrated biological washing deodorization tower

The utility model relates to the field of odor purification, in particular to an integrated biological washing deodorization tower, which comprises a tower body, a gas inlet and a gas outlet are respectively arranged at the bottom and the top of the tower body, a plurality of purification layers are arranged on the tower body along the flowing direction of odor, and each purification layer comprises an adsorption tank and a spraying piece. A through hole for spraying liquid to flow is formed in the bottom of the adsorption tank, the adsorption tank is used for adsorbing organic pollutants in odor, and the spraying part is arranged at the upper part of the adsorption tank, is communicated with the sewage aeration tank and is used for spraying high-alkalinity microorganism-rich spraying water in the aeration tank into the tower body. According to the chemical washing type odor purification device disclosed by the utility model, odor is strongly sprayed and adsorbed by utilizing high alkalinity and high-activity
