Description
Technical field
The present invention relates to a kind of hollow fiber film assembly and comprise the membrane bioreactor of this hollow fiber film assembly.
Background technology
Membrane bioreactor (MBR) is a kind of water treatment device that is combined with biologic treating technique by membrane separation technique, keeps the high activity sludge concentration in bioreactor, is one of efficient sewage disposal technology in current forward position.The characteristics of membrane bioreactor are that traditional biological treatment and membrane separation technique are combined, remove the second pond of traditional biological technique, simplify the technique of membrane bioreactor (MBR), floor space greatly reduces, save cost, and because the centrifugation of MBR membrane separation technique, so that can keep very high volumetric loading, mud underload and long mud age in the treatment pond, be not subjected to the impact of sludge bulking, realized separating fully of hydraulic detention time and mud mud age, effluent quality is good.
Hollow fiber film assembly is the parts of membrane bioreactor most critical.The hollow fiber film assembly of prior art, for example Chinese invention patent discloses the disclosed immersed hollow fiber membrane module of CN1509801A, mainly comprise membrane module framework and branched single membrane module, wherein single membrane module comprise upper and lower end and be filled in during the external pressure hollow-fibre membrane.There is following deficiency in the hollow fiber film assembly of this structure: in actual application, because pollutant and the microorganism mixed liquor of high concentration, and membrane bioreactor is to utilize the negative pressure suction to produce water, so that the hollow-fibre membrane surface forms the phenomenon of producing the enrichment of water pollutant matter easily, produce concentration polarization, be attached to the lower end of single membrane module, along with running time is more and more longer, increasing colloidal solid adheres to and other organic or inorganic small particles enter doughnut membrane aperture inside from the lower end of single membrane module, cause the lifting of membrane bioreactor operating pressure, the two ends of external pressure hollow-fibre membrane are arranged on the upper of single membrane module simultaneously, the bottom, non-detachable, caused carrying out online or off-line when cleaning, can cause inner hollow-fibre membrane under stronger sluicing effect, produce easily the fracture of hollow-fibre membrane and the phenomenon of the mutual winding between the hollow-fibre membrane, shortened the service life of hollow-fibre membrane.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of improved hollow fiber film assembly is provided.
The present invention also will provide a kind of improved membrane bioreactor simultaneously.
For solving the problems of the technologies described above, a kind of technical scheme that the present invention adopts is:
A kind of hollow fiber film assembly, it comprises collector pipe and a plurality of hollow fiber film unit, particularly, described hollow fiber film unit comprises that the diaphragm that can be arranged on the collector pipe and upper end are fixed on many hollow-fibre membranes on the diaphragm with dismantling, the upper end of described hollow-fibre membrane offers the intercommunicating pore in order to the connected set water pipe, and the bottom of hollow-fibre membrane freely vertical and sealing arranges.
Further, the two ends of described collector pipe are respectively the water sides, and its underpart is provided with a plurality of joints, and described diaphragm is threaded mutually with joint.Preferably, be provided with sealing ring between diaphragm and the joint, improve the sealing that joint is threaded with diaphragm.More specifically, described collector pipe comprises and being horizontally disposed with and two ends consist of the body of water side that the bottom of this body is provided with delivery port, and collector pipe also comprises the connecting portion that is fixedly installed on water outlet, is formed with described a plurality of joint on this connecting portion.
According to a concrete and preferred aspect of the present invention, the upper end of hollow-fibre membrane is bonded on the diaphragm; Sealant sealing is passed through in the bottom of hollow-fibre membrane.
Preferably, a plurality of hollow fiber film units are arranged side by side.
Further, the quantity of the hollow-fibre membrane that contains of described hollow fiber film unit is 10 ~ 1000.By the film silk quantity of film unit, density that can controlling diaphragm assembly film silk.
Another technical scheme according to the present invention is: a kind of biofilm reactor, it includes above-mentioned hollow fiber film assembly.
Because the employing of technique scheme, the present invention compared with prior art has following advantage:
The present invention makes between hollow fiber film unit and the collector pipe and removably is connected, so, hollow-fibre membrane can be pulled down easily and clean and change, and when wherein a certain or some film unit damages, only need to change corresponding film unit and get final product, the replacing of hollow-fibre membrane is very flexible; In addition, hollow fiber film unit of the present invention can consist of by unit diaphragm production and assembling, production efficiency is high, the bottom of hollow-fibre membrane freely vertical and sealing arranges, except the binding agent that can save the casting of film silk, also can reduce the impact of solid and activated sludge deposition, prevent the generation of enrichment phenomenon under the long-term use of hollow-fibre membrane.Therefore, hollow fiber film assembly of the present invention compared with prior art, not only filtering accuracy improves, production efficiency improves, cost, and longer service life.
Description of drawings
The present invention will be further described in detail below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is the structural representation according to hollow fiber film assembly of the present invention;
Fig. 2 is broken section enlarged diagram among Fig. 1;
Wherein: 1, collector pipe; 10, joint; 11, body; 12, connecting portion; 2, hollow fiber film unit; 20, hollow-fibre membrane; 21, diaphragm.
The specific embodiment
As depicted in figs. 1 and 2, the hollow fiber film assembly according to present embodiment comprises collector pipe 1 and a plurality of hollow fiber film unit 2.Collector pipe 1 comprises and being horizontally disposed with and two ends consist of the body 11 of water side that the bottom of this body 11 is provided with delivery port, and collector pipe 1 also comprises the connecting portion 12 that is fixedly installed on water outlet, and the downside of this connecting portion 12 is formed with a plurality of joints that are arranged side by side 10.Hollow fiber film unit 2 comprises 10 ~ 1000 hollow-fibre membranes 20 and diaphragm 21, and wherein, the upper end of hollow-fibre membrane 20 casts on the diaphragm 21 by binding agent and offers intercommunicating pore with connected set water pipe 1; The bottom of hollow-fibre membrane 20 freely vertically and with sealant sealing arranges.Diaphragm 21 is by screw thread and sealing ring jointing 10, thereby whole hollow fiber film unit 2 can be pulled down from collector pipe 1 easily.
Hollow fiber film assembly of the present invention, by the film silk quantity of control hollow fiber film unit, can control the density of MBR membrane module film silk, and, in the local damage of film silk, realize changing easily, making rational use of resources cuts the waste, and single-ended casting less the use of binding agent and mould of plastics, reduced production cost, realize the unit matrix production of hollow-fibre membrane MBR assembly, simple to operate, enhance productivity.Because the film silk of MBR membrane module is free droop, little solid and activated sludge particles be the sedimentation bottom under the effect that gravity and aeration wash away, and has avoided because deposition causes being full of mud around the hollow-fibre membrane lower end film silk being produced irreversible pollution.Sum up, hollow fiber film assembly of the present invention compared with prior art, not only filtering accuracy improves, production efficiency improves, cost, and longer service life.
