Abstract

This utility model discloses a visible light catalytic wastewater treatment device, relating to the field of wastewater treatment technology. It includes: a reaction vessel containing a photocatalyst for degrading organic matter in wastewater; a stirrer within the reaction vessel for mixing the wastewater and the visible light photocatalyst; an organic wastewater pipe connected to the reaction vessel; an industrial lamp located above the reaction vessel to provide visible light and activate the photocatalyst; and a suspension separator connected to the reaction vessel for separating the degraded suspension and returning the resulting solid-liquid mixture to the reaction vessel for recycling. This wastewater treatment device utilizes the visible light catalytic properties of a zinc tungstate and zinc molybdate composite material, solving the problems of low degradation efficiency and reliance on ultraviolet light in traditional technologies, thus reducing secondary pollution. Furthermore, the device adopts a modular component design, facilitating rapid disassembly, expansion, and maintenance, adapting to different scales of wastewater treatment needs.
