Abstract
A kind of submerged flat sheet membrane element of membrane bioreactor is characterized in that being made up of integrated component that comprises rectangle supporting layer, water conservancy diversion layer, frame and the filter membrane that covers on it.Integrated component two water conservancy diversion layers up and down is provided with hundreds of curbs, and two curb communicates with its perpendicular filtrate guiding groove respectively, and the filtrate guiding groove connects the filtrate fairlead, and filtrate fairlead exit is equipped with filtrate suction pipe connecting.Filter membrane covers integrated component up and down on two the curb, and by binding agent and four edges frame sealing and fixing.Positively effect of the present invention is: flat sheet membrane frame, supporting layer and water conservancy diversion layer one constitute, it is many to have overcome existing flat membrane element level, be in operation because the incident drainage of effect of hydrodynamic shear has improved water flux, prolonged the life-span of membrane element.
Description
Technical field
The invention belongs to the membrane bioreactor filter film technology, particularly relate to a kind of submerged flat sheet membrane element of membrane bioreactor.
Background technology
Membrane Bio-reactor Technology is being developed rapidly aspect sewage disposal and the water resources reuse in recent years.Membrane bioreactor has following advantage: sludge concentration height, excess sludge are few, and sludge retention time is long, and organic matter removal efficient is higher, and denitrification effect is good, and the facility compact floor space is few, uses more extensive.At present, the immersed type flat membrane element shape of application is a rectangular sheet, is that engineering plastics are the frame of material all around, is provided with the filtrate extraction channel in the frame, and filtrate extraction channel exit can connect the filtrate suction tube; Is supporting layer in the middle of the flat membrane element, the outside both sides of middle support layer are followed successively by water conservancy diversion layer and filter membrane, more than each layer composition plain film holder around in the frame and sealing and fixing.Because plain film is made up of the differing materials multilayer, so drainage taking place easily in the long-time running process, causes the effluent quality instability.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, it is the submerged flat sheet membrane element of membrane bioreactor of one that a kind of supporting layer, water conservancy diversion layer and frame are provided.
Whole flat membrane element is a rectangular panels, and the element of long 500～2000mm, wide 350～550mm, thick 9～16mm different size size is arranged.
The present invention is achieved by the following technical solutions:
A kind of submerged flat sheet membrane element of membrane bioreactor is characterized in that being made up of integrated component that comprises rectangle supporting layer, water conservancy diversion layer, frame and the filter membrane that covers on it.
Described integrated component two water conservancy diversion layers up and down is provided with hundreds of curbs,
The cross section of described curb is an arc, and wide is 0.5～3mm, is 0.5～2mm deeply;
Be proof strength, curb of integrated component is parallel to the minor face frame, and the another side curb is parallel to long margin frame, and two curb communicates with its perpendicular filtrate guiding groove respectively
The filtrate guiding groove connects the filtrate fairlead, and filtrate fairlead exit is equipped with filtrate suction pipe connecting.
Filter membrane covers integrated component up and down on two the curb, and by binding agent and four edges frame sealing and fixing.
Positively effect of the present invention is: flat sheet membrane frame, supporting layer and water conservancy diversion layer one constitute, it is many to have overcome existing flat membrane element level, be in operation because the incident drainage of hydrodynamic shear effect has improved water flux, prolonged the life-span of membrane element.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is rotated down structural representation after 180 ° for Fig. 1.
Fig. 3 is an internal structure diagrammatic cross-section of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As Figure 1-3, integrated component 1 is made by hydrophilic engineering plastics among the figure, integrated component about in the of 1 two water conservancy diversion layers be provided with hundreds of parallel with long margin frame or minor face frame respectively curbs 2, the cross section of described curb 2 is an arc, its width is 1mm, is 1mm deeply; Two curb 2 respectively with its 3 vertical linking to each other of perpendicular filtrate guiding groove.Filtrate fairlead 4 and filtrate guiding groove 3 communicate.Filtrate fairlead 4 exits are equipped with filtrate suction pipe connecting 5, and filter membrane 6 covers on the curb 2, uses binding agent and frame sealing and fixing all around.
When the suction system of membrane bioreactor aspirates the negative pressure operation, filter membrane 6 internal layers are negative pressure state, the liquid in the film outside is inhaled into curb 2 by filter membrane 6, and after filtrate guiding groove 3 flows to filtrate fairlead 4 and filtrate suction pipe connecting 5, is sucked out membrane bioreactor again.
