Embodiment 1

[0044] The slanted plate catalytic reaction tower designed and produced according to the technical scheme of the present invention and Deyu sewage cleaning machine (providing ozone, mixing ozone and wastewater) are connected through pipelines for sewage treatment, and the treated sewage is better than ozone alone. The reaction time is shortened, the reaction efficiency is improved, the ability to degrade COD is greatly improved, and the effect on color and odor is better.

[0045] For example: after the inclined plate catalytic reaction tower is connected with the Deyu sewage cleaning machine to treat a certain printing and dyeing wastewater, after 30 minutes of treatment, the decolorization effect is obvious, and the COD is reduced from the original 1660mg / L to 907mg / L, and the degradation rate reaches 45.4 %. See the table below for details:

[0046] Water Quality Parameters as it is After 3 hours of treatment Degradation rate COD (mg / L) 1660 907 45....

Abstract

The invention provides a tilting plate catalytic reaction tower which comprises a base, wherein a reaction tower main body is arranged on the base; the reaction tower main body consists of a tower bottom, a packing layer and a tower top from bottom to top; a tower bottom seal is arranged at the bottom of the tower bottom; the tower bottom seal is connected with an evacuation or mud discharge valve; an ozone water inlet and a wastewater inlet are formed in a side wall of the tower bottom; catalyst solid packing is filled in the packing layer; a tower top seal head is arranged on the tower top; and a wastewater outlet is formed in a side wall of the tower top. The tilting plate catalytic reaction tower is simple in structure, low in cost and easy to operate and manage and is suitable for sewage treatment, a special structure in the tower and the filled inert noble metal catalyst solid packing are utilized, ozone is subjected to catalytic oxidation to generate hydroxyl radicals to oxidize and degrade readily oxidizable substances in the sewage, and the aim of eliminating organic pollution and odor is achieved. The tilting plate catalytic reaction tower can be combined with an ozone technology and is applied to the field of large-scale sewage treatment.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a slanted plate catalytic reaction tower used in the field of sewage treatment. Background technique [0002] With the continuous development of human society and the continuous expansion of the city, the water consumption and drainage of the city are increasing, which aggravates the tension of water use and the pollution of water quality, and the environmental problems are becoming more and more prominent. The resulting water crisis has become a socio-economic important constraints to development. [0003] my country's water resources are relatively poor. If the discharged sewage can be treated and recycled, it will not only reduce environmental pollution, but also be of great significance to alleviate the problem of water shortage. [0004] Advanced oxidation technology has a good treatment effect in the field of sewage treatment, and ozone oxidation technology is one of them, ...
