Description
Technical field
The utility model belongs to external membrane bioreactor field, particularly a kind of rolling microtubular membrane assembly.
Background technology
Membrane bioreactor (Membrane Bio-Reactor, MBR) is a kind of being combined with biological processing unit by film separation unit, with the new type water treatment technology of secondary sedimentation tank in membrane separating process replacement traditional activated sludge process.Membrane bioreactor (Membrane Bioreactor, MBR) is compared traditional second pond treatment process and is had obvious advantage, is mainly reflected in:
1, Separation of Solid and Liquid can be carried out efficiently, go out aqueous suspension and turbidity close to zero, can direct reuse;
2, the effect of efficiently damming of film, makes microorganism be dammed completely in reactor, achieves being separated completely of reactor hydraulic detention time (HRT) and sludge retention time (SRT);
3, the microorganism concn in reactor is high, improves the speed of biochemical reaction;
4, with the second pond that microtubular membrane assembly instead of in traditional activated sludge process (CAS), floor space is significantly reduced, process equipment is concentrated; Easily realize Automated condtrol.
Membrane bioreactor divides from the structure of film can be divided into hollow-fibre membrane MBR, dull and stereotyped MBR and tubular type MBR.The position relationship put from microtubular membrane assembly and biological reaction pool divides, and can be divided into immersion MBR and external MBR.External tubular membrane bioreactor compares with the membrane bioreactor of other types, and its main advantage is that tubular membrane has excellent intensity, antipollution, anti-oxidant and acid-proof alkaline (pH1-13); Pure water flux high (300 ~ 500LMH) is 5-10 times of submerged hollow fiber milipore filter; Can filter activity sludge concentration up to 30g/L, the life-span is long.Floor space is little, can on-line cleaning, and Operation and Maintenance is more convenient.But its major defect is that in unit volume, effective film area is little, and observable index is higher.And putamina must be changed when changing film by periosteum together that have, causes unnecessary waste, adds the investment cost of equipment.
Based on the place of the above-mentioned deficiency of tubular membrane, those skilled in the art constantly examine whether to replace tubular membrane with rolled film, both can increase effective film area, and are convenient for changing film again and do not abandon putamina.Rolling microtubular membrane assembly generally includes putamina element, microtubular membrane element and the adapter being connected putamina element and microtubular membrane element.
The structure of existing rolling microtubular membrane assembly as shown in Figure 1, comprises the center water producing pipe 10 of side-wall hole, diaphragm 20, produces water cloth 30, dense water flow-guiding screen 40 and end cap 50.Three limits that adjacent two diaphragm 20 therebetween last layers produce water cloth 30 form film bag by certain sealing means bonding, and be separated by by dense water flow-guiding screen 40 between film bag and film bag, film bag is tightly wound on the water producing pipe of center together with flow-guiding screen.Former water enters from a side of rolling microtubular membrane assembly, along the runner gap between the diaphragm that flow-guiding screen 40 is formed and face is flow through in the direction being parallel to central tube, retain dense water to flow out from another side of rolling microtubular membrane assembly, and to enter in film bag through the product water of diaphragm and flow to center water producing pipe, finally flow out from center water producing pipe.End cap 50 structure is similar with wheel, by outer rim, center hub and be uniformly distributed along the circumference, the support floor that is connected and fixed outer rim and wheel hub is one-body molded.Its effect mainly reduces the risk that film twists in fluid unwinding under the Pressure Drop effect of out-of-date generation, protects the two ends of rolling microtubular membrane assembly in the process of carrying impaired simultaneously, rolling microtubular membrane assembly can also be made to erect and place.End cap can form with various metal material manufacture, also can by injection-moulding plastic.
The housing of existing rolling microtubular membrane assembly is identical with the material of end socket, is stainless steel or fiberglass entirely.Stainless Steel Shell makes the weight of whole putamina large, and the investment cost of equipment is high.And the intensity of fiberglass end socket is little relative to stainless steel, install and operation process in, due to putamina and putamina, putamina is connected uncontrollable mechanics problems such as the stress that causes of bias is concentrated with female pipeline, very easily break and cause leakage.The connection of putamina and main line, the connection of putamina and putamina is mainly by connecting pipings.A large amount of connecting pipings not only increases the investment of equipment, and easily cause microtubular membrane element and pipeline stress concentrate etc. mechanics problem, increase leak point.And make whole system huge, take limited space.
This rolling microtubular membrane assembly bonds fixing by means of only the medial surface of center hub and the end of center water producing pipe.Rolling microtubular membrane assembly is carried or installing/dismounting process in, add the percussion of the pressure fluid when equipment runs outward, end cap is very easily reversed, loosen and come off, thus lose to film volume protective effect.The upper and lower end face supporting floor is concordant with the upper and lower end face of wheel hub with outer rim.When end cap is in installation site as shown in Figure 1, supports the end that floor is close to film volume, make formation dead band, laminating position, form the potential growth point of microorganism, accelerate the pollution course of membrane component, shorten its service life.The runner of microtubular membrane element generally adopts parallel or network runner (as shown in Figure 2), and the corner of grid is very easily hidden dirt and received and form potential growth of microorganism point, accelerates the pollution of microtubular membrane element, increases concentration polarization, reduce its service life.Its conventional runner is 46mil, and for the fluid containing certain suspension of rolling microtubular membrane assembly process, this runner is very easily blocked, and cannot normally work.
