Description

TECHNICAL FIELD

[0001] The utility model relates to industrial wastewater treatment technical field especially industrial wastewater ozone oxidation reaction pool device. BACKGROUND

[0002] Industrial wastewater ozone oxidation reaction pool device as the key equipment of industrial wastewater treatment, plays a vital role in the environmental protection field. It uses the strong oxidizing property of ozone to effectively degrade organic pollutants in industrial wastewater, significantly improves the wastewater quality, so that it meets the discharge standard or meets the requirements of subsequent treatment process. This reaction pool device has been widely used in many industrial fields such as chemical industry, printing and dyeing, pharmaceutical industry, etc. In actual operation, industrial wastewater ozone oxidation reaction pool device usually has the following key components:

[0003] 1. Reaction pool body: as the core space of reaction, generally made of corrosion-resistant materials such as carbon steel anticorrosion, glass steel or stainless steel, to ensure that the structure is stable and not corroded when long-term contact with industrial wastewater and strong oxidizing ozone.

[0004] 2. Water and gas distribution system: water distribution device, such as perforated pipe water distributor, overflow weir water distributor, etc., is responsible for distributing wastewater evenly in the reaction pool; gas distribution device, such as microporous aerator, perforated aeration pipe, etc., disperses ozone gas into wastewater in the form of small bubbles, increases the contact area of the two, and improves the utilization rate of ozone.

[0005] 3. Catalyst filler layer: filled with composite porous high-strength silicon aluminum catalyst carrier, and doped with transition metal, rare metal, rare earth metal and other catalyst components, which can accelerate the decomposition of ozone, produce more strong oxidizing hydroxyl radicals, and improve the ozone oxidation efficiency.

[0006] 4. Tail gas treatment system: including exhaust pipe and ozone decomposer, which discharges the remaining ozone tail gas after reaction, and decomposes ozone into oxygen after ozone decomposer, to prevent ozone pollution of the atmospheric environment.

[0007] At present, in order to improve the treatment effect of industrial wastewater ozone oxidation reaction pool device, various technical means are adopted in the industry. Some enterprises use fixed bed type reaction pool, which makes wastewater flow stably in the pool and fully contacts with fixed ozone and catalyst for reaction. This method is suitable for industrial wastewater treatment scenes with stable water quality and quantity. Some enterprises use fluidized bed type reaction pool, and the catalyst is in fluidized state in the pool, which greatly increases the contact opportunity with wastewater and ozone, and has stronger adaptability to water quality and quantity changes. In addition, some advanced reaction pool devices are provided with an internal circulation system, which sends the gas and wastewater in the upper part of the reactor into the lower part of the reactor for circulation reaction through the gas circulation mechanism and wastewater circulation mechanism, prolongs the reaction time, and improves the treatment effect.

[0008] However, the above-mentioned existing implementation still has some problems to be solved. In terms of reaction efficiency, due to the difficulty in achieving absolute uniformity of water flow and ozone distribution in the reaction tank, the wastewater in some areas is not fully contacted with ozone, which limits the overall oxidation reaction efficiency, cannot fully exert the oxidation ability of ozone, and further affects the wastewater treatment effect. In the treatment of refractory organic matter, the conventional ozone oxidation reaction rate is slow, the treatment period is long, and it is difficult to meet the increasingly strict environmental protection standards and the efficient needs of industrial production. In view of these problems, the present application proposes an innovative solution to improve the reaction efficiency and enhance the treatment capacity of refractory organic matter by partitioning the reaction tank and introducing ultraviolet technology. The partitioning design can accurately control the reaction conditions according to the characteristics of wastewater in different reaction stages to realize staged reaction. Ultraviolet light can strengthen the ozone oxidation process, generate more strong oxidizing free radicals, accelerate the decomposition of organic matter, make the reaction tank device operate more efficiently, and have better treatment effect, which can better meet the complex and variable industrial wastewater treatment needs.
