Ozone catalytic membrane water treatment system and method thereof

Abstract

The invention belongs to the technical field of water treatment, and discloses an ozone catalytic membrane water treatment system and a method thereof. The ozone catalytic membrane water treatment system comprises a wastewater collection module, a wastewater pretreatment module, a central control module, an activated carbon adsorption module, an ozone catalytic membrane preparation module, an ozone catalysis module, a circulation module, a secondary catalysis module, a purified water detection module and a purified water recycling module. The ozone catalytic membrane provided by the invention is simple in preparation method, can realize stable catalytic activity and prolong the service life of the catalyst, and has stronger catalytic capability and high catalytic efficiency. The impurities in industrial wastewater are adsorbed before ozone catalysis, ozone catalysis interference is small, and the effect is better; water circulation is performed after ozone catalysis, so that the catalyzed water flows through the ozone catalytic membrane again for secondary catalysis, the purification degree of the obtained water is better, and the water can be reused.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an ozone catalytic membrane water treatment system and method. Background technique [0002] At present, as my country's water pollution problems become increasingly prominent, the improvement of sewage treatment discharge standards has become the general trend. In recent years, the upgrade and transformation of sewage treatment plants in various places are being carried out one after another. For upgrading and upgrading, especially for sewage treatment plants containing industrial wastewater, it is difficult to meet the required standards only by upgrading the biochemical treatment process, and it is necessary to add an advanced oxidation process after biochemical treatment. [0003] The current advanced oxidation methods include Fenton method, ozone oxidation method, electrolytic catalytic method, wet oxidation method, photochemical synergistic oxidation me...
