Abstract
A membrane component used for an MBR (membrane biological reactor) and provided with a central tube comprises hollow fiber membrane yarns (2), a central aeration tube (3), an epoxy blocking tube plate (4), an epoxy blocking dead end (5) and a porous outer tube (6), wherein the hollow fiber membrane yarn (2) is arranged inside the porous outer tube (6) through the epoxy blocking tube plate (4) at one end and the epoxy blocking dead end (5) at the other end; the central aeration tube (3) is arranged between two bundles of hollow fiber membrane yarns (2); and the porous outer tube (6) is provided with pores. The advantages are as follows: the membrane component is simple to install, convenient to adjust and durable; especially, the utilization rate of gas is improved and the content of oxygen dissolved in water is improved, therefore, the membrane component is beneficial to biochemical reaction and has an obvious effect of removing harmful substance; the stain resistance of the membrane is improved; and the flux is stable.
Description
Technical field
The utility model relates to the novel polysulfone hollow fiber ultrafiltration membrane system of a kind of MBR of being used for system, belongs to sewage treatment area.
Background technology
At present, hollow fiber ultrafiltration membrane is used for that the MBR system is many to be existed with curtain formula kit form, promptly is poured into the two ends of multi beam hollow fibre filament respectively with epoxy and forms so-called curtain formula assembly in two plastic tubes, then this assembly formation module that is together in parallel.There is following shortcoming in this form: film silk root is easily broken, influences effluent quality thereby when aeration, more be prone to fracture of wire; Mostly membrane material is the stronger materials of toughness such as PVDF and PP, and the material of PS or PES excellent performance is owing to easily broken being excluded of silk, material alternative little; Simultaneously, aeration is many to make aeration rate big by the peripheral aeration of aeration tube at the film silk, not enough to the strength of turbulence of water, thereby bad to the cleaning performance of film.
Summary of the invention
The utility model technical problem to be solved provide a kind of have install simply, easy to adjust, durable in use, be prone to the novel polysulfone hollow fiber ultrafiltration membrane system that is used for the MBR system that cleans.
The utility model adopts following technical scheme:
A kind of MBR with central tube uses membrane module; Comprise hollow-fibre membrane silk, center aeration tube, epoxy shutoff tube sheet, epoxy shutoff dead end, porous outer tube; The epoxy shutoff dead end of epoxy shutoff tube sheet and the other end of described hollow-fibre membrane silk through an end is installed in and comprises in the shell; Described center aeration tube is arranged between the two intrafascicular hollow fiber film silks, and described shell is provided with the hole.
The diameter of described center aeration tube is the 1-3 millimeter.
The advantage of the utility model is to have installs simply, easy to adjust, durable in use; Particularly the utilization rate of gas improves, and oxygen in water improves, and helps biochemical reaction; Removal effect for harmful substance in the water is obvious, and the stain resistance of film improves, flux stabilized.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
The specific embodiment
As shown in Figure 1; A kind of MBR with central tube uses membrane module; Comprise hollow-fibre membrane silk 2, center aeration tube 3, epoxy shutoff tube sheet 4, epoxy shutoff dead end 5, porous outer tube 6; Described hollow-fibre membrane silk 2 is installed in the porous outer tube 6 through the epoxy shutoff tube sheet 4 of an end and the epoxy shutoff dead end 5 of the other end, and center aeration tube 3 is arranged between the two intrafascicular hollow fiber film silks 2, and porous outer tube 6 is provided with the hole.The diameter of center aeration tube 3 select for use into the 1-3 millimeter for well.
The utility model is produced according to the manufacturing approach of hollow fiber film assembly; Just porous outer tube 6 is processed to porous, and each assembly middle part all is provided with center aeration tube 3 simultaneously, is hollow-fibre membrane silk 2 around the center aeration tube 3; Gas in the center aeration tube 3 can play stripping and cleaning action to the surface of any hollow-fibre membrane silk 2 like this; Increased the contact probability of gas and water simultaneously, made the dissolved oxygen in water amount increase, the utilization rate of gas improves.The diameter of center aeration tube 3 is advisable with the 1-3 millimeter, the hole size on the porous outer tube 6 with the intensity of not damaging shell for well; All hollow-fibre membrane silks 2 are cast in the porous outer tube 6 after being wrapped up by the plastics protecting wire net, during use, equally assemble the preparation method of these assemblies according to the ultrafiltration module, enter into biochemistry pool to them then and get final product.
Claims (2)
1. the MBR with central tube uses membrane module; It is characterized in that: comprise hollow-fibre membrane silk (2), center aeration tube (3), epoxy shutoff tube sheet (4), epoxy shutoff dead end (5), porous outer tube (6); Described hollow-fibre membrane silk (2) is installed in the porous outer tube (6) through the epoxy shutoff tube sheet (4) of an end and the epoxy shutoff dead end (5) of the other end; Described center aeration tube (3) is arranged between the two intrafascicular hollow fiber film silks (2), and described porous outer tube (6) is provided with the hole.
