Problems solved by technology

[0002] In the field of sewage and waste gas treatment, the existing technology is still incomplete. The malodorous waste gas on the sewage itself is an unstable substance, and the treatment is also very difficult. The existing single substance is combined with a reaction tower to decompose the waste gas or a single ultraviolet light. Photodecomposition is not perfect, it can only process part of the waste gas or the treatment of waste gas is incomplete, resulting in residual waste gas that can still pollute the environment and endanger residents

Abstract

The invention provides wet-type oxidation / composite photochemical combined treatment equipment for waste gas of sewage and a treatment method. The wet-type oxidation / composite photochemical combined treatment equipment comprises a gas collecting fan, a wet-type oxidation tower, a single-wave photochemical reaction device, a composite photocatalystic device, a chemical auxiliary oxidation-degradation device and an exhausting fan which are connected in series and in sequence by ventilating pipelines. The treatment method comprises the following steps that the waste gas of the sewage is treated by the wet-type oxidation tower, the single-wave photochemical reaction device, the composite photocatalystic device and the chemical auxiliary oxidation-degradation device, and then obtaining qualified air. The wet-type oxidation / composite photochemical combined treatment equipment and the treatment method provided by the invention have the beneficial effects that many problems of the treatment of the waste gas of the sewage in the prior art are solved, and the waste gas of the sewage can be comprehensively treated, and the waste gas can be almost eliminated completely; stinky waste gas of the sewage is treated by combining a photochemical reaction with a photocatalyst and wet-type oxidation and the like, so that the treatment equipment and the treatment method have the advantages of high efficiency and no secondary pollution and the like.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to wet oxidation / composite photochemical combined sewage and waste gas treatment equipment and treatment methods. Background technique [0002] In the field of sewage and waste gas treatment, the existing technology is still incomplete. The malodorous waste gas on the sewage itself is an unstable substance, and the treatment is also very difficult. The existing single substance is combined with a reaction tower to decompose the waste gas or a single ultraviolet light. Photodecomposition is not perfect, and it can only treat part of the waste gas or treat the waste gas incompletely, resulting in residual waste gas that can still pollute the environment and endanger residents. Contents of the invention [0003] The invention provides wet oxidation / compound photochemical combined sewage and waste gas treatment equipment and a treatment method, which can effectively control sewage a...
