Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] like figure 1 As shown, the ultrafiltration membrane regenerated water treatment device of integrated catalytic oxidation and loaded catalyst of the present invention is made up of airtight reaction tank body 5 and the ultrafiltration membrane assembly 8 of loaded catalyst, wherein the ultrafiltration membrane assembly 8 of loaded catalyst is composed of ozone releaser 1. Composed of aerator 2, ultraviolet lamp 3, ultrafiltration membrane loaded with catalyst 4, connecting pipe and support frame. The air output by blower 6 is sent into the catalyst-loaded ultrafiltration membrane module 8 through a pipeline, and released through the aerator 2, and the ozone generated by the ozone generator 7 is sent into the catalyst-loaded ultrafiltration membrane module 8 through a pipeline, and is discharged through the aerator 2. The release device ...

Abstract

The invention discloses an ultrafiltration membrane reclaimed water treatment device integrating catalytic oxidation and a supported catalyst and belongs to the field of water pollution treatment equipment. The reclaimed water treatment device comprises a closed tank and an ultrafiltration membrane assembly arranged in the tank. An ultrafiltration membrane of the supported catalyst in the ultrafiltration membrane assembly is spaced with an ultraviolet lamp. An aerator and an ozone releaser are distributed below the ultrafiltration membrane, water flow can be pushed to move from bottom to top, the dual functions of water flow and bubbles rich in ozone can promote the jitter state of the hollow fiber ultrafiltration membrane, the catalyst supported on the ultrafiltration membrane can be evenly irradiated easily through ultraviolet, the mass transfer function among the ultrafiltration membrane of the supported catalyst, ozone and pollutants can be enhanced, and the effect of catalytic oxidation is improved. The water treatment device integrates the functions of suspended matter and colloid interception, organic pollutant decomposition, sterilization and the like, and a reliable guarantee is provided for resource regenerative utilization of sewage or preprocessing of nanofiltration and reverse osmosis.

Description

technical field [0001] The invention belongs to the field of water pollution control equipment, and in particular relates to a novel ultrafiltration membrane regeneration water treatment device. Background technique [0002] The application of ultrafiltration in reclaimed water treatment or pretreatment of nanofiltration and reverse osmosis is one of the research hotspots in recent years. Reclaimed water treatment or pretreatment of nanofiltration and reverse osmosis require that the content of impurities in water such as suspended solids, colloids, organic pollutants and microorganisms be as low as possible. Due to the small pore size, usually between 0.002 and 0.1 μm, the ultrafiltration membrane can effectively intercept suspended solids, most colloids, large molecular weight organic matter and larger-sized microorganisms. In the secondary drainage of sewage treatment plants, there are a certain amount of especially soluble and refractory organic pollutants and a large n...
