Abstract
The invention relates to a novel submerged flat membrane element, which comprises a middle support plate (2), wherein the two plate surfaces of the same plate are provided with a plurality of vertical guide channels (1); and the membranes (3) are arranged on the two surfaces of the middle support plate (2). The novel submerged flat membrane element is characterized in that: side compression bars (4) are arranged on the left and right sides of the middle support plate (2), and an upper end part (5) and a lower end part (6) are arranged on the upper and lower ends of the middle support plate (2) respectively; the upper end part (5) and the lower end part (6) are provided with two suction pipes (7) respectively; a plurality of water gathering channels (8) are formed on the middle support plate (2); and the membranes (3) are covered the outside of the water gathering channels (7). In the invention, four suction pipes adopted are favorable for the backwash of the membranes when the membranes are used for a period of time; the novel submerged flat membrane element has the characteristics of easy water outflow, large effective processing area, large flow and the like, improves the effective efficiency of aeration, reduces washing time and saves energy; the membranes can reach 2.5 meters at most; and the occupied area is smaller on the premise of identical sewage treatment amount.
Description
Technical field
The present invention relates to a kind of sanitary sewage and Industrial Wastewater Treatment equipment, is that the biological respinse that a kind of activated sludge process combines with biomembrane is handled waste fitment, also is a kind of immersed type plain membrane element of novel membrane bioreactor.
Background technology
In recent years, membrane bioreactor has obtained fast development both at home and abroad, and as a kind of new and effective sewage disposal device.The advantage of membrane bioreactor is: active sludge biological is very abundant in the membrane bioreactor; Do not receive the mud expansion effects; Effluent quality is good after treatment, and the water quality requirement of water reuse is specially adapted to middle or small sewage treatment and scattering sewage treatment field in can satisfying.It is the widest a kind of that the submerged flat membrane bioreactor is that membrane bioreactor is used.But there is easy clogging in the membrane component of flat sheet membrane bioreactor in the market, has influenced water rate and treatment effect, also exists backwashing time long simultaneously, shortcomings such as cleaning performance difference.
Summary of the invention
The object of the invention is exactly the deficiency to above-mentioned prior art, provides a kind of developing result good, and water yield is big, and treatment effect is good, the novel submerged flat membrane element that aeration rate is little.
The technical scheme that the present invention adopts is following:
A kind of novel submerged flat membrane element; The two plate faces that include same block of plate are provided with the intermediate support plate of the vertical curb of multiple tracks, on two plate faces of intermediate support plate, diaphragm are installed, and it is characterized in that the said intermediate support plate left and right sides is equipped with the side press strip; Its upper and lower end is separately installed with top fitting and lower end-piece; Respectively be provided with two suction tubes on top fitting and the lower end-piece, on intermediate support plate, be provided with a plurality of grooves that catchment, said membrane covered is in the outside of the groove that catchments.The groove that catchments on the said intermediate support plate is a rectangle.
The groove that catchments on the said intermediate support plate is connected.
Beneficial effect of the present invention has:
When making plastic board frame model, on top fitting and lower end-piece, respectively reserve two suction tubes, help the backwash after diaphragm uses a period of time like this; Has easy water outlet, characteristics such as effectively processing area is big, and flux is big; Improve the effective efficiency of aeration, reduced washing time and energy savings, and because the diaphragm maximum height can reach 2.5 meters; Under same sewage load prerequisite, have the littler characteristics of floor space.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the part sectioned view of Fig. 1 of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further:
Like accompanying drawing 1, shown in 2; The two sides of intermediate support plate 2 of the present invention is provided with the vertical curb 1 of multiple tracks; And diaphragm 3 is installed on the two sides of intermediate support plate 2, and said intermediate support plate 2 left and right sides are equipped with side press strip 4, and its upper and lower end is separately installed with top fitting 5 and lower end-piece 6; Respectively be provided with two suction tubes 7 on top fitting 5 and the lower end-piece 6, sewage can be after diaphragm 3 outer walls infiltrate inwall from the curb 1 of 2 liang of plate faces of middle gripper shoe by suction tube 7 sucking-offs.For improving water-taking efficiency, the present invention is provided with a plurality of grooves 8 that catchment on intermediate support plate 2, can improve sewage load greatly.The groove 8 that catchments preferably is adopted as rectangle, and the groove 8 that catchments on the intermediate support plate 2 is connected, thereby further improves water-taking efficiency.
The undeclared part of other that the present invention relates to is identical with prior art.
