The aerating apparatus comprises an aerating main pipe and aerating branch pipes, wherein each aerating branch pipe comprises a branch pipe body and an arc clamping groove, the inner diameter of each arc clamping groove is matched with the outer diameter of the aerating main pipe, the junction of each branch pipe body and the corresponding arc clamping groove is provided with a hollow pipeline, each branch pipe is communicated with the aerating main pipe through the corresponding hollow pipeline, and the aerating main pipe and the aerating branch pipes are fixed through self-locking buckles. The distance among the aerating branch pipes can be adjusted according to requirements, so that the uniformity of aeration can be controlled; moreover, the aerating main pipe is connected with the aerating branch pipes through the self-locking buckles, so that the connection between the aerating main pipe and each aerating branch pipe is firm.
Description
Technical field
The utility model belongs to sewage treatment area, particularly a kind of plate membrane bioreactor aerating apparatus.
Background technology
Film-bioreactor (be called for short MBR) is the generally acknowledged advanced person's in the world today sewage disposal and sewage recycling technology, and it is the bio-reactor in the ultrafiltration in membrane separation technique, micro-filtration or nanofiltration membrane component and biological sewage treatment to be mutually combined and the novel treatment system that forms.This integrated form new technology of combined is dissolved in one to the high efficient separation technology of the biological degradation of bio-reactor and film.Film-bioreactor can the degree of depth degraded municipal administration, life, trade effluent, but process water outlet reuse afterwards, realize sewage recycling.Film-bioreactor can be divided into external placed type and immersion.Wherein the submerged membrane bio-reactor can be divided into again tubular fibre curtain type membrane and plate and frame flat sheet membrane.And flat sheet membrane and membrane module are the core components of immersion MBR technology, membrane module mainly comprises: aeration tube, aeration case, membrane element, film case, flexible pipe and header.Flat membrane component mainly comprises: back up pad, film lining cloth, filter membrane, water outlet.Sewage in biochemistry pool enters the film chamber by the suction function of vacuum primingpump by filter membrane, after the charge for remittance chute through in the film chamber, by water outlet, is extracted.This process there will be the transmission resistance that separation efficiency and selectivity are incurred loss, and the influential transmission resistance of membrane sepn process tool is had a lot, stops up the contaminated loss caused because of the film surface and is wherein a kind of.For controlling and reduce the pollution on film surface, aerating apparatus is set usually below film, utilize bubble the film surface to be washed away to alleviate the obstruction on film surface.Existing aerating apparatus is generally the design of " U " type,: open several micropores on " U " type stainless steel pipes, having micropore to produce bubble is washed away the film surface, because micropore is to be distributed on " U " type pipeline, so position distribution just must be limited, tend to cause aeration inhomogeneous, affect the separation efficiency of filter membrane.
The utility model content
The purpose of this utility model is to provide a kind of and can be adjusted the distance between each aeration branch pipe as required, thereby the homogeneity to aeration is regulated and controled, and the aeration house steward is connected with aeration branch pipe and adopts the self-locking buckle, the connection that makes aeration house steward and aeration branch pipe is the plate membrane bioreactor aerating apparatus more firmly.
The technical solution that realizes the utility model purpose is:
A kind of plate membrane bioreactor aerating apparatus, comprise the aeration house steward, aeration branch pipe, described aeration branch pipe comprises arm and circular arc draw-in groove, the internal diameter of circular arc draw-in groove matches with aeration house steward's external diameter, and there is hollow pipeline arm and circular arc draw-in groove junction, and arm is communicated with the aeration house steward by hollow pipeline, aeration house steward and aeration branch pipe are fixed by the self-locking buckle, on the arm of aeration branch pipe, have aerating pore.
The utility model compared with prior art, its remarkable advantage:
1, with existing flat sheet membrane aerating system, all adopt stainless steel to compare, the utility model can adopt engineering plastics, cost.
2, existing flat sheet membrane aerating system all adopts " U " stainless steel tube perforate integral type, and the distribution of aerating pore is restricted, and aeration is inhomogeneous.The utility model adopt aeration house steward and aeration branch pipe through specific cards link connect fixing, and the distance between each aeration branch pipe can be adjusted as required, homogeneity to aeration can regulate and control as required, therefore can need to carry out the flexible design adjustment according to different operating modes, greatly strengthen its subject range.
3, in the utility model plate membrane bioreactor aerating apparatus, the aeration house steward is connected the design of employing self-locking buckle with aeration branch pipe, make aeration branch pipe and aeration house steward's connection more firm, can stand for a long time the vibrations that produce due to aeration, never drop-off.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the view that the utility model aeration branch pipe separates with buckle.
Fig. 3 is the view that the utility model aeration branch pipe is combined with buckle.
Embodiment
As Figure 1-3:
A kind of plate membrane bioreactor aerating apparatus, comprise aeration house steward 1, aeration branch pipe 2, described aeration branch pipe 2 comprises arm 20 and circular arc draw-in groove, the internal diameter of circular arc draw-in groove matches with aeration house steward 1 external diameter, and there is hollow pipeline 201 arm and circular arc draw-in groove junction, and arm 20 is communicated with aeration house steward 1 by hollow pipeline 201, aeration house steward 1 and aeration branch pipe 2 are fixing by self-locking buckle 21, on the arm 20 of aeration branch pipe 2, have aerating pore.
Circular arc draw-in groove 202 opening ends of aeration branch pipe 2 have two card bases 202, and card base 202 is the triangular form structure.
Self-locking buckle 21 sizes match with the circular arc draw-in groove opening of aeration branch pipe 2, and self-locking buckle 21 has two bayonet sockets 210, and the position of offering coordinates with the position of two card bases 202 of the circular arc draw-in groove opening end of aeration branch pipe 2.
The hollow pipeline 201 of aeration branch pipe 2 and circular arc draw-in groove junction stretches out one section.
