Specific embodiment
MBR membrane modules as shown in Figure 1, including support bar 100, the first positioner 200, the second positioner 300, film
Core 400 and delivery outlet 500, wherein, the first positioner 200 is installed in one end of support bar 100, the second positioner
300 other ends for being arranged on support bar 100, film core 400 are then arranged on support bar 100 and are axially positioned on the first positioner
200 and second between positioner 300；Delivery outlet 500 is generally located on the first positioner 200 or the second positioner 300
On；Additionally, inside support bar 100 and/or 100 surface of support bar is additionally provided with flow-guiding channel, flow-guiding channel both with film core 400
Delivery port is turned on, and is turned on the delivery outlet 500 of MBR membrane modules, so as to by by the water body of filtration of 400 output of film core from defeated
MBR membrane modules are derived in outlet 500.Above-mentioned MBR membrane modules put shape with sleeping generally by support as immersion MBR membrane modules
During formula is arranged on membrane bioreactor and positioned at the top of aerator, MBR membrane modules immersion during use is carried out at aeration
In the sewage of reason, these sewage are filtered by film core 400 under filter pressure effect again, finally from the delivery outlet of MBR membrane modules
Water body has been filtered in 500 outputs.
As shown in Fig. 2 above-mentioned film core 400 includes multiple being socketed on support bar 100 and along the axle of the support bar 100 successively
The sealing device 420 being adapted to each membrane component 410 to spaced membrane component 410 and respectively.Specifically, such as Fig. 2 to 6
Shown, the membrane component 410 includes diaphragm 411, and the diaphragm 411 includes the first filtration membrane 411a and the first filtration membrane
The second filtration membrane 411b that 411a is oppositely arranged and by the first filtration membrane 411a and the second filtration membrane 411b it is stacked and
The cavity 411c being formed between the first filtration membrane 411a and the second filtration membrane 411b, cavity 411c are by through
Through hole 411d and support bar between one filtration membrane 411a and the second filtration membrane 411b and for being engaged with support bar 100
The water conservancy diversion gap 430 formed between 100 and through hole 411d turns on, and the water conservancy diversion gap 430 is i.e. by being arranged on support bar
Inside 100 and/or the flow-guiding channel on 100 surface of support bar is turned on the delivery outlet 500 of MBR membrane modules.
The operation principle of above-mentioned film core 400 is：Sewage to be filtered filters thin from first under filter pressure effect respectively
The cavity 411c that film 411a and the second filtration membrane 411b is penetrated between the first filtration membrane 411a and the second filtration membrane 411b
In, due to cavity 411c and through between the first filtration membrane 411a and the second filtration membrane 411b and be used for and support bar
The 100 through hole 411d conductings being engaged, and between through hole 411d and support bar 100, there is water conservancy diversion gap 430, therefore, ooze
Enter the water body of filtration in cavity 411c to flow in water conservancy diversion gap 430, so by being arranged on inside support bar 100 and/or
The flow-guiding channel on 100 surface of support bar flows to the delivery outlet 500 of MBR membrane modules.Due to being provided with sealing device 420 in film core 400,
Therefore, it is possible to avoid filtering interpenetrating between water body and sewage to be filtered.
Filter efficiency is caused to decline in the past due to being susceptible to bonding between diaphragm 411, the service life of diaphragm is reduced,
Spacer web is provided between adjacent diaphragm 411.As shown in Fig. 2 to 6, interval is not set in this specific embodiment
Net, the substitute is and be additionally arranged anti-offset supporting construction 411e in the cavity 411c of each diaphragm 411.This specific embodiment
In concrete anti-offset supporting construction 411e for adopting include being stacked and placed on the first filtration membrane 411a and the second filtration membrane 411b it
Between gripper shoe 411f and the pilot hole 411g for being arranged in gripper shoe 411f and coordinating with support bar 100.Wherein, gripper shoe
The shapes and sizes of 411f are preferably adapted with cavity 411c, so preferable to the support effect of diaphragm.Gripper shoe 411f is preferred
Thickness is adopted for 0.3 to 2 millimeter of flat board, the intensity for ensureing gripper shoe 411f is so can ensure that, is ensured that diaphragm 411
Integral thickness is relatively thin, and then guarantees the setting quantity of 100 upper diaphragm 411 of support bar.Some can be opened up to engrave in gripper shoe 411f
Empty hole slot, it would however also be possible to employ the flat board of solid construction is used as gripper shoe 411f.When using the flat board of solid construction as support
During plate 411f, cavity 411c can essentially be divided into two and substantially be separated and parallel cavity by gripper shoe 411f, rise
To preferably shunting, guide functions.Gripper shoe typically can be made using rigid materials such as rigid plastics.
As shown in Fig. 2 in this specific embodiment, the concrete structure of sealing device 420 is：The two of each membrane component 410
Side is respectively equipped with sealing ring 421；The sealing ring 421 includes sealing ring body 421a being socketed on support bar 100 and squeezes
Pressure is arranged on the sealing ring 421b between sealing ring body 421a and adjacent diaphragms 411；In 410 diaphragm 411 of each membrane component
Gripper shoe 411f 410 both sides of membrane component sealing ring 421 clamping force effect under be vertically arranged with support bar 100.It is right
In above-mentioned sealing device 420, due to being respectively provided on two sides with sealing ring 420 in each membrane component 410, positioned at 410 film of each membrane component
Gripper shoe 411f in piece 411 is vertical with support bar 100 under the clamping force effect of the sealing ring 420 of 410 both sides of membrane component
Arrange, it is ensured that the steadiness positioned between gripper shoe 411f and support bar 100, it is ensured that gripper shoe 411f is to diaphragm 411
Anti-offset support effect.
