Abstract
A double-layer flat membrane module comprises upper layer supports, lower layer supports and a bottom layer aeration membrane box, the bottom end of the upper layer supports is provided with a water collection tube reserved outlet, one side of the top end of the upper layer supports is provided with a water collection tube, one side of the top end of the lower layer supports is provided with a water collection tube, the top end of the lower layer supports is provided with inclined guiding U-shaped racks along the edge of the periphery of the lower layer supports, the bottom end of the upper layer supports is inserted to the top end of the lower layer supports through guidance of the guiding U-shaped racks, the top end of the aeration membrane box is provided with inclined guiding U-shaped racks along the edge of the periphery of the aeration membrane box, the bottom end of the lower layer supports is inserted to the top end of the aeration membrane box through guidance of the guiding U-shaped racks, two sides of the upper end and the lower end of each of the upper layer supports and the lower layer supports are respectively provided with a lug, the lug is provided with a corresponding guiding hole, and a guiding post is inserted to the guiding hole. A double-layer membrane frame is adopted, so the effective membrane area per unit of area is multiplied, and the required quantity of aeration frames is halved. The specific aeration demand per unit of membrane area is decreased, so the running cost per water treatment capacity is reduced.
Description
Technical field
The present invention relates to a kind of sewage disposal device, particularly relate to a kind of two-layer equation Flat Membrane sewage disposal device.
Background technology
China is a lack of water country, and sewage disposal and reuse are the effective measures developing water resource.Reusing sewage be by municipal sewage, trade effluent by after the device processes such as membrane bioreactor, use it for greening, flushing, supplement and view and admire that water body etc. is non-drinks object.Membrane bioreactor is the Novel state sewage disposal system that membrane separation technique and biologic treating technique organically combine.Replace traditional biological treatment technology end second pond with membrane module, in bioreactor, keep high activity sludge concentration, improve biological treatment organic loading.
In membrane bioreactor (MBR), film puts into bioreactor with membrane module form, existing membrane module normally can not be separated integrative-structure both multiple membrane component forms with aerator, basic structure is in a membrane module casing, top is multiple membrane component (such as tubular membrane or Flat Membrane), and below is aerator.Membrane module, after operation one time, need propose to carry out off-line cleaning and regeneration, to recover membrane flux, extends the service life of film.
In recent years, MBR technology obtains develop rapidly in wastewater treatment and reuse field at home.But in current MBR sewage treatment project, membrane module used mostly is hollow-fibre membrane, there is easy fracture of wire, contamination resistance is poor, cleaning is frequent, can not the shortcoming such as on-line cleaning.Trace it to its cause is that comparatively hollow-fibre membrane unit occupied area sewage load is low for existing plate film assembly, the complex structure of single device own, installation difficulty is high, the cycle is long, many groups Flat Membrane equipment is unsuitable compact arrangement in same membrane cisterna, the civil engineering amount matched greatly, costly, is not suitable for heavy civil MBR sewage treatment project.
Summary of the invention
The object of the present invention is to provide one large compared with sewage load in its unit occupied area of existing like product, many groups equipment room can compact arrangement, install and operation maintenance easy, operating cost is cheap, is specially adapted to the double-layer plate membrane module of down-stream process engineering.
For realizing the object of the invention, provide following technical scheme: a kind of double-layer plate membrane module, it is characterized in that the aeration film case comprising upper and lower two-layer support and bottom, plate film assembly is provided with in upper and lower two-layer support, upper layer bracket bottom is provided with the reserved outlet of collector pipe, side, upper layer bracket top is provided with collector pipe, side, lower floor support top is provided with collector pipe, lower floor support top is provided with the U-shaped frame of guiding of inclination along support edge, bay is led in lower floor support top by the U-shaped frame of guiding in upper layer bracket bottom, described aeration film case top is also provided with the U-shaped frame of guiding of inclination along edge, bay is led in layer aeration film case top by the U-shaped frame of guiding in lower floor support bottom, the upper and lower side both sides of described upper and lower two-layer support are provided with auricle, auricle offers corresponding pilot hole, lead is inserted with in pilot hole.
As preferably, aeration film case bottom level is provided with aeration supervisor, and upper regularly arranged the aeration branch pipe of aeration supervisor, every root aeration branch pipe all has aperture, distal opening, and described aeration supervisor is connected with air blast by pipeline.
As preferably, upper and lower two-layer cantilever tip is provided with hanger.
Beneficial effect of the present invention: the present invention adopts two-layer equation film framework that the effective film area of unit occupied area can be made to double, and required aeration framework quantity reduces by half.Declining (aeration demand/membrane area) than aeration demand in addition due to per membrane area, thus reduce the operating cost of unit water treatment amount.
