Abstract

The invention provides a device for photocatalytic degradation of malodorous gas. The device comprises a lighttight container, an adjustable ultraviolet lamp in the lighttight container and multiple glass beads in the lighttight container. Outer surfaces of the glass beads are coated with TiO2 photocatalytic layers. The device for photocatalytic degradation of malodorous gas utilizes the glass beads as photocatalyst carriers, improves photocatalytic degradation effects by glass bead refraction and reflection effects, has good deodorization effects, has a simple structure, can be miniaturized, and has a wide application prospect.

Description

technical field [0001] The invention relates to the field of malodorous gas treatment, in particular to a photocatalytic degradation device for malodorous gas. Background technique [0002] In a landfill, garbage decomposition is a natural process, which can be divided into aerobic decomposition and anaerobic decomposition according to the degree of oxygen demand. In the initial stage of landfill, the organic components in the garbage, such as protein and fat, generate ammonia gas NH with pungent odor under the action of aerobic bacteria. 3 etc.; with the insufficient oxygen supply, anaerobic microorganisms play a role, and anaerobic bacteria decompose organic matter into incomplete oxidation products such as sulfur-containing compounds, such as hydrogen sulfide H 2 S, mercaptans, etc., and nitrogen-containing compounds such as amines, amides, and other malodorous gases. Malodorous gases can be divided into 5 categories according to their composition: ①Sulfur-containing co...
