Abstract

The invention belongs to the field of water treatment application, and provides a device for photocatalytic advanced treatment of wastewater, which includes a water inlet pipe, a nozzle and a pool body, and the water inlet pipe is connected to the pool body through a nozzle; the pool body includes a photocatalytic part and multiple The medium combination treatment part, the multi-media combination treatment part is located directly below the photocatalytic part; the present invention is an advanced treatment device composed of thin water film multi-layer oxidation and multi-media combination of wastewater, which can efficiently treat waste water It has strong oxidizing ability, good adaptability, mild degradation conditions, no need to add oxidant, and the treatment process is cheap, safe and easy to operate.

Description

technical field [0001] The invention belongs to the field of water treatment applications, in particular to a device for photocatalytic advanced treatment of wastewater. Background technique [0002] The photocatalytic wastewater technology belongs to the technical field of water treatment. This technology has the advantages of novelty, high efficiency, and no selectivity to waste water. It is especially suitable for the degradation of unsaturated hydrocarbons, and the reaction conditions are relatively mild, and there is no secondary pollution, so it has a good application prospect. Its working principle is that when there is a semiconductor powder catalyst in the organic wastewater, a certain amount of various forms of active oxygen and free radicals can be produced in the system after a certain intensity of ultraviolet light irradiation, because these active oxygen and free radicals have High oxidation potential, so it can interact with organic matter and degrade it, and...
