In order to remove the pollution substances such as the mud that is adsorbed on film silk surface, aerating apparatus is provided with bottom film group device, by aeration effect, the gas-liquid two-phase turbulent flow of the instability upwards flowed is produced in film group device, film silk does not stop dynamic in current, air-flow and current flow axially through film silk surface alternately along film silk, under the washing away of biphase gas and liquid flow, constantly the pollution substance on film silk surface is taken away, thus keep film silk surface cleaning clean, reduce the mistake flow resistance on film silk surface, realize film silk continuously pumping water.
Find through long-time running, some fibre shape or particulate material is always had in sewage lagoon, after these materials enter film group device, often easily be suspended on film silk, under the promotion of current, constantly upwards wriggle, finally climb to the top of film silk, namely the root of putamina place film silk is gone up, one is agglomerated at this, along with foreign material are cumulative year in and year out, film silk is strutted to both sides, make top-film bundle enlarged volume, decrease current gap reserved between two membrane modules, the serious gap between two membrane modules of can causing is lost, plug current current path, affect the normal operation of film group device.
[utility model content]
For solving the problems of the technologies described above, the MBR membrane module structure that the utility model provides a kind of structure simple, easy to use, can overcome the drawback of film silk top deposition, ensures that membrane module can normally run for a long time.
In order to realize foregoing invention object, the technical solution adopted in the utility model is:
A kind of MBR membrane module structure, comprise putamina, lower shell and filter screen pocket, thousands of filtering membrane silk up to a hundred is had between described upper and lower putamina, the two ends up and down of filtering membrane silk are sealed respectively and are moulded in upper and lower putamina, filtering membrane silk, upper putamina and lower shell are arranged in filter screen pocket, bottom and the lower shell of filter screen pocket link together, and form water stream channel between the outer wall of adjacent two filter screen pockets.

[embodiment]
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
A kind of MBR membrane module structure, as shown in Figure 1, comprise thousands of filtering membrane silk 1 up to a hundred, the top of filtering membrane silk 1 connects upper putamina 2, the bottom of filtering membrane silk 1 is provided with lower shell 3, and the two ends envelope of filtering membrane silk 1 is moulded in upper putamina 2, lower shell 3, and filtering membrane silk 1, upper putamina 2 and lower shell 3 are arranged in filter screen pocket 4, bottom and the lower shell 3 of filter screen pocket 4 link together, and form water stream channel 5 between the outer wall of adjacent two filter screen pockets 4.
Wherein, the top end opening of described filter screen pocket 4, top is uniformly distributed the belt that some fine count fibers are made, the netted filter bag that filter screen pocket 4 is made for fine count fiber.
MBR membrane module structure of the present utility model is in concrete use, and because filter screen pocket is that fine count fiber is made, quality is light.And filter screen pocket eyelet is comparatively sparse, good water permeability, crosses flow resistance very little, does not almost have inhibition to current air-flow.Filter screen pocket does not affect the swing of filtering membrane silk under two-phase turbulence effect, and the axis of current to filtering membrane silk surface is washed away.Filter screen pocket top is uniformly distributed the belt that some fine count fibers are made, and plays certain fixed action, but does not affect filter screen pocket and swing back and forth together with filtering membrane silk in current, air-flow.This random to-and-fro movement can promote that in filtering membrane silk, air water exchanges, and can also get rid of the mud sticking to filter screen pocket surface simultaneously.Filter screen pocket upper opening contributes to the air water flowing in pocket.When sewage is by filter screen pocket, filter screen pocket has filtered a part of mud impurity, and this is equivalent to the hydraulic load decreasing filter screen pocket inner filtration film silk.This is conducive to provide the operating flux of filtering membrane silk, reduces transmembrane pressure.
Compare with flat sheet membrane MBR film group device, the arrangement form of this filter screen is equivalent to dull and stereotyped diaphragm.But filter screen pocket cross membrane flux far away higher than flat sheet membrane, the water quality of certain filter screen pocket can not with flat sheet membrane ratio.The unit volume intimal surface that after increasing filter screen pocket, this new membrane assembly has a hollow-fibre membrane amasss the large feature of large process flow, also has the advantage of stable, the unsuitable deposition of flat sheet membrane simultaneously; The eyelet of filter screen pocket is selected to be of moderate size, and aperture is too large, can not stop that fiber sludge passes through.The too little current air-flow that affects again in the aperture of filter screen pocket passes through, and affects film group device and normally runs.
The above embodiment is just preferred embodiment of the present utility model, not limits practical range of the present utility model with this, the equivalence change that all shapes according to the utility model, structure and principle are done, and all should be covered by protection domain of the present utility model.
