Abstract
The utility model provides a hollow fibrous membrane assembly for a submerged membrane bio-reactor. The membrane assembly of the utility model is formed by a plurality of hollow fibrous membrane bundles; hollow fibrous membranes of the hollow fibrous membrane bundles have an open lower end and a sealed upper end; the lower ends of the hollow fibrous membranes are hermetically fixed by epoxy resins and a lower bundle end cover; the upper ends of the hollow fibrous membranes are fastened by a short rubber tube aluminium feeding ring and are connected with the upper bundle end cover by adhesive; the upper bundle end cover and the upper end cover of the assembly are connected by a spring to guarantee the flexible connection of the upper ends; the hollow fibrous membrane bundles operate in an external pressure manner; and effluent flows through a water outlet at the lower ends of the hollow fibrous membrane bundles, enters a water collection cavity in the lower end cover of the assembly, passes through a water outlet pipe in the center of the assembly from bottom to top, and flows out of the upper surface of the assembly. When an MBR (membrane bio-reactor) is in operation, the hollow fibrous membrane bundles with a certain degree of freedom are jittered due to the circulated water flow and air flow, so that the hollow fibrous membranes are not easy to be contaminated by sludge suspending liquid fine-grained particles, organic matters and the like; and besides, the shearing stress is resolved in the movement of the hollow fibrous membranes. The hollow fibrous membranes of the utility model are reinforced through internal hydrophilic synthetic fiber; therefore, membrane yarns are not easier to damage.
Description
Technical field:
The utility model belongs to the membrane bioreactor water treatment facilities, is specifically related to a kind of membrane module of integrated submerged membrane bioreactor.
Background technology:
Membrane bioreactor (MBR) is a kind of novel, the sewage disposal technology efficiently that biologic treating technique combines with membrane separation technique.It mainly is made up of bioreactor and membrane module two units, and sewage at first enters reactor, because the sludge concentration height removes the organic matter efficiency height, denitrification effect is good.Film separation unit is mainly used in Separation of Solid and Liquid, and microbial solid can be trapped within the reactor effectively, guarantees stable effluent quality.Hollow fiber film assembly was integrated closely in the past, and the effective film area is big.Yet under the strong loop condition of sludge suspension liquid, doughnut bears certain horizontal tension, therefore often has the fracture of wire phenomenon to take place, and influences effluent quality.
Summary of the invention:
The utility model overcomes the weak point of above technology, has proposed a kind of hollow fiber film assembly that is used for integrated submerged membrane bioreactor.This hollow fiber film assembly can bear than hightension, and water permeability is good.
The technical scheme that the utility model provides is:
A kind of hollow fiber film assembly that is used for submerged membrane bioreactor, comprise the many hollow fiber membrane bundles of forming by hundreds of hollow-fibre membrane silks, on restraint end cap, restraint end cap, assembly upper end cover, assembly bottom end cover and center outlet pipe down, the center outlet pipe links to each other with the interior collect cavity of assembly bottom end cover, the film silk upper end that it is characterized in that forming the fine film bundle of hollow seal, the lower end be opening and be connected with epoxy resin and the following end cap seal of restrainting; The fine film Shu Shangduan of hollow is with rubber tube and aluminium circle, tighten and be connected with last bundle end cap with binding agent, on restraint end cap usefulness spring and be connected with the assembly upper end cover, guarantee that like this hollow fibre film Shu Shangduan is flexible coupling; Described film filament length degree is two times of hollow fiber membrane bundle, and hollow fiber membrane bundle is formed in doubling, and bending part is the upper end of hollow fiber membrane bundle; Described hollow-fibre membrane silk is made up of the capillary hydrophily synthetic fibers in doughnut rete and its chamber, capillary hydrophily synthetic fibers outer wall and doughnut rete inwall fit tightly, the material of capillary hydrophily synthetic fibers is the synthetic fibers with chemical graft or the modification of plasma grafting method, polyvinylidene fluoride (PVDF) the material manufacturing of doughnut rete.
。The utility model hollow-fibre membrane silk is with the method that sprays the doughnut rete to be coated on the capillary hydrophily synthetic fibers outer wall to make, and filter membrane is more even, and precision is higher.Therefore hollow-fibre membrane has higher-strength hydrophily again, and fluid mobility can be good, good water permeability, and the shear strength height has overcome the easy fracture of wire phenomenon of existing hollow fibre membrane component; The hollow fiber membrane bundle upper end is to be connected with spring with the assembly cover plate, hollow fiber membrane bundle just has certain free degree like this, when the strong circulation time of activated sludge suspension, hollow fiber membrane bundle is shaken along with the turbulent fluctuation of fluid, be difficult on the hollow-fibre membrane like this being stopped up by mud granule deposition in the suspension, membrane resistance diminishes, and film is vulnerable to pollution not.
The utility model hollow fiber film assembly has overcome the easy fracture of wire phenomenon of existing hollow fibre membrane component, and have that contamination resistance is strong, water flux is high, characteristics such as long service life, operating cost are low.
Description of drawings

The specific embodiment:
Consult accompanying drawing, 1-hollow fiber membrane bundle, 2-hollow-fibre membrane silk, the last bundle of 3-end cap, 4-be bundle end cap, 5-spring, 6-center outlet pipe, 7-assembly upper end cover, 8-assembly bottom end cover, 9-rubber tube, 10-aluminium circle, 11-doughnut rete, 12-capillary hydrophily synthetic fibers down
Hollow-fibre membrane silk 2 is made of capillary hydrophily synthetic fibers 12 and doughnut rete 11, is to be that inner core (capillary hydrophily synthetic fibers) spraying polyvinylidene fluoride (doughnut rete) is made to become the hydrophily synthetic fibers with chemical graft method surface modification.The hollow-fibre membrane silk 2 of many two times of film Shu Changdu is bent into hollow fiber membrane bundle 1, and bending part is hollow fiber membrane bundle 1 upper end, imperforation; The other end is hollow fiber membrane bundle 1 lower end, is opening.Film bundle lower end links to each other with following bundle end cap 4 sealings with epoxy resin, has the outlet of catchmenting to link to each other with assembly bottom end cover 8 interior collect cavities on the following bundle end cap 4; Film Shu Shangduan is with there being one section short sebific duct 9 of plasticity to entangle, and the outside adds that aluminium circle 10 usefulness specific purpose tools tighten, again with binding agent and 3 bindings of last bundle end cap, on restraint end cap 3 usefulness springs 5 and link to each other with assembly upper end cover 7.
During operation, waste water enters under suction function in the hollow-fibre membrane silk 2 after filtration, and through the hollow fiber membrane bundle 1 downward collect cavity that flows into assembly bottom end cover 8, collect cavity water flows out membrane module from bottom to top by center outlet pipe 6.
