Embodiment 1

[0020] Such as figure 1 , an upflow reaction and separation integrated powder resin purifier, including swirl water distribution and concentration component 1, steady flow component 2 and particle separation component 3 three components, the purifier is formed from bottom to top in the reactor by the bottom There are four upward water and powder resin swirl reaction areas, powder resin-containing swirl water steady flow area, water and powder resin separation area, and purified water outlet area; among them, the swirl water distribution and concentration component 1 realizes swirl through symmetrical tangent water inlet design. The water is distributed by flowing water; the steady flow component 2 is provided with a double-layer reflection plate, and the upper part of the steady flow component 2 is provided with a particle separation component 3; as image 3 Shown: 20m per strand 3 / h Printing and dyeing wastewater biochemical treatment Tail water (COD about 80mg / L, chroma ab...

Embodiment 2

[0022] structured as figure 1 As shown, a strand of 20m 3 / h Printing and dyeing wastewater biochemical treatment Tail water (COD about 80mg / L, chroma about 45 times) is passed into the purifier figure 2 The swirling water distribution and concentration assembly 1, which is arranged symmetrically with eight horizontal tangents, is fully hydrocyclone-stirred at the bottom of the reactor with 10% volume concentration of powder resin with a particle size of 300 μm. After swirl reaction for 30 minutes, the resin-containing swirl The flowing water passes through the flow stabilization component 2 to slow down the turbulent flow of the water body, and then through the particle separation component 3 to realize the complete separation of the resin from the water. The separation area is 2.31m 2 , the angle A between the resin separation zone and the boundary of the reaction zone is 26 degrees, and the final separated water is discharged from the upper clear water zone, 10m 3 / h The...

Embodiment 3

[0024] structured as figure 1 As shown, a strand of 10m 3 / h Domestic sewage biochemical treatment tail water (COD about 50mg / L, chromaticity about 45 degrees) enters an upflow reaction and separation integrated powder resin purifier for purification reaction, and passes through twelve swirling flow cloths arranged symmetrically on horizontal tangent lines The water and concentration component 1 enter the purifier, and react at the bottom of the purifier with a 15% volume concentration of powdered resin with a particle size of 50 μm. After 15 minutes of swirl reaction, the resin-containing swirling water passes through the steady flow component 2 to slow down the turbulence of the water body, and then passes through the particle Separation module 3 realizes the complete separation of resin from water, and the separation area is 0.71m 2 , the angle A between the separation zone and the reaction zone boundary is 0 degrees, and the final separated water is discharged from the up...

Abstract

The invention discloses an upflow reaction and separation integrated powder resin purifier and a purification method thereof, belonging to the field of purifier preparation. Its built-in swirl water distribution and concentration components, steady flow components and particle separation components form the upflow water and powder resin swirl reaction zone in the purifier, the swirl water steady flow zone containing powder resin, the separation zone of water and powder resin and the purification The water outlet area realizes resin reaction, separation, settling internal reflux, concentration and multiple functional integrated powder resin purifier structures. The vertical layout of the upflow in the present invention effectively reduces the floor area of ​​the equipment; the high-concentration resin flows back to the reaction zone through separation and gravity sedimentation, cancels the resin backflow power equipment, and reduces the operating cost; the water distribution and concentration components of the stable swirl flow realize hydraulic Dual functions of swirl flow and saturated resin concentration, on the one hand, form hydrodynamic swirl flow power, avoiding the operation failure of traditional mechanical agitation, on the other hand, concentrate the volume concentration of saturated resin and reduce operating costs.

Description

technical field [0001] The invention relates to water treatment environmental protection equipment and a purification method thereof, in particular to an upflow reaction and separation integrated powder resin purifier and a purification method thereof. Background technique [0002] Resin adsorption technology is a water purification technology with broad application prospects in sewage / wastewater treatment. In recent years, powdered magnetic resin has attracted special attention. Due to its small particle size and magnetic properties, it has the unique advantages of fast response speed and good sedimentation performance. Powdered resin can not only carry out full-mixing reaction and pipeline transportation like coagulant, but also can strengthen settlement by magnetic self-aggregation. Compared with the traditional resin fixed bed operation mode, the powder resin process can use two processes of mixing reaction and resin separation to realize continuous water purification t...
