Photocatalytic oxidation treatment system of sludge odor and method for treating sludge odor by utilizing same

The invention discloses a photocatalytic oxidation treatment system of sludge odor and a method for treating the sludge odor by utilizing the same, relating to the field of solid waste treatment. The photocatalytic oxidation treatment system of the sludge odor comprises an odor collector, an odor filter, a fan, a photocatalytic oxidation purifier, an active carbon adsorption device and a controller. The method for treating the sludge odor comprises the following steps of: collecting odor generated by each step in the sludge treatment process by the odor collector, charging the odor to the odor filter at a flow speed of 1,000-2,500m /h, filtering the odor, sending the filtered odor to the photocatalytic oxidation purifier through the fan, treating the purified odor through the active carbon adsorption device and discharging the treated odor. The photocatalytic oxidation treatment system of the sludge odor and the method for treating the sludge odor by utilizing the photocatalytic oxidation treatment system, disclosed by the invention, treat the sludge odor through photocatalytic oxidation and have the advantages of no side effect, no secondary pollution, high treatment efficiency and the like, and can be applied to odor treatment of a large/middle sludge treatment project.
