High-concentration industrial wastewater catalytic oxidation treatment equipment and treatment method

Abstract

The invention relates to the technical field of sewage treatment, in particular to high-concentration industrial wastewater catalytic oxidation treatment equipment and a treatment method.The high-concentration industrial wastewater fed into a treatment pond can be accurately defined and metered through matched arrangement of a metering assembly and a water inlet assembly, and a catalytic oxidizing agent is weighed and metered in combination with the metering assembly according to the wastewater amount; corresponding assemblies are arranged at the joint of the water inlet assembly and the treatment pond, so that in the operation process, the catalytic oxidizing agent can be conveniently put into the treatment pond from the water inlet end, the dispersion effect of the catalytic oxidizing agent is improved by utilizing the impact acting force of water flowing, and meanwhile, the waste of the wastewater is reduced. The effect of the aeration assembly is utilized to enhance the action effect when a subsequent catalytic oxidant acts on wastewater, and the arrangement structure of the transparent cover pipe is adopted to ensure that uniform light can be dispersed at each angle in the treatment tank, so that the treatment effect can be improved when a photocatalyst is adopted.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to catalytic oxidation treatment equipment and a treatment method for high-concentration industrial wastewater. Background technique [0002] Wastewater and waste liquid discharged from industrial production are collectively referred to as industrial waste water, and its direct discharge will cause serious pollution to the environment and directly or indirectly affect people's life safety. Therefore, waste water and waste liquid discharged from industrial production should undergo necessary treatment. Only after it reaches the standard can it be discharged. [0003] At present, the technology of catalytic oxidation treatment of wastewater has been developed rapidly, and due to the excellent characteristics of the catalytic oxidation treatment method, the technology of catalytic oxidation treatment of industrial wastewater has been popularized and applied in a large area, fo...

AI Technical Summary

Problems solved by technology

[0004] In recent years, with the complexity of wastewater discharge caused by industrial development, a large amount of high-concentration organic industrial waste liquid has been formed, which has the characteristics of high concentration of organic pollutants, high toxicity, and poor elimination of biochemical reactions. Oxidation treatment equipment is difficult to meet the technical requirements. The reason is that the amount of catalytic oxidant used in catalytic oxidation treatment is added based on the intuition or experience of wastewater treatment personnel, resulting in poor stability of the amount used in the treatment of waste liquid discharged from each batch. It is difficult to form an effective ratio with wastewater, resulting in poor treatment effect of final high-concentration industrial wastewater; at the same time, the existing wastewater treatment equipment is stirred in the treatment tank to achieve uniform dispersion of catalytic oxidant and wastewater, to improve the contact between catalytic oxidant and wastewater, However, due to the unreasonable setting of the structure of the treatment pool, it is difficult to effectively treat the wastewater at some corners and corners, resulting in poor treatment effect
