Abstract
The utility model relates to an immersion type flat sheet membrane element of a membrane bioreactor, which is characterized in that the immersion type flat sheet membrane element consists of an integral component and a filter membrane, wherein the integral component comprises a rectangular support layer, flow guide layers and edge frames, the filter membrane is covered on the integral component, hundreds of flow guide grooves are formed on the flow guide layers formed on the upper surface and the lower surface of the integral component, the flow guide grooves of both sides are respectively communicated with filtrate guide grooves which are vertical to the flow guide grooves, the filtrate guide grooves are connected with filtrate outlet guide holes, and filtrate pumping connection pipes are arranged at outlets of the filtrate outlet guide holes. The filter membrane is covered on the flow guide grooves of the upper surface and the lower surface of the integral component, and is fixed to four edge frames through adhesive agents in a sealed way. The utility model has the advantages that the edge frames, the support layer and the flow guide layers of the flat sheet membrane are integrally formed, the problems of multilayer and easy occurrence of water leakage phenomenon in the operation because of the action of the fluid shearing force is solved, the water flux is improved, and the service life of the membrane element is prolonged.
Description
Technical field
The utility model belongs to the membrane bioreactor filter film technology, particularly relates 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 resource 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 immersion 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 different materials multilayer, so drainage taking place easily in the long-time running process, causes the effluent quality instability.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and 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 utility model is achieved through 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 tube connector.
Filter membrane covers integrated component up and down on two the curb, and by binding agent and four edges frame sealing and fixing.
Good effect of the present utility model 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 component.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is rotated down structural representation after 180 ° for Fig. 1.
Fig. 3 is an internal structure generalized section of the present utility model.
The specific embodiment
The utility model is described in further detail 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 tube connector 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 tube connector 5, is sucked out membrane bioreactor again.
