The membrane bioreactor is characterized in that: the membrane bioreactor comprises a membrane holder body (7), in which a plurality of flat membrane elements are arranged, each flat membrane element comprises a supporting plate (1) and membranes (2), the membranes (2) are arranged on both sides of the supporting plate (1), the circumferential side edges of the supporting plate (1) and the membranes (2) are fixed by pressing plates (3), the pressing plates at both sides are thicker than the upper and the lower pressing plates, the upper pressing plate (3) is provided with a suction tube (4), and the suction tubes (4) on the flat membrane elements are connected with a main water suction tube (8) through water tubes. The membrane bioreactor is characterized by good backflushing effect, high antifouling capability, high membrane flux, long service life, high water yield rate, more sufficient and uniform aeration, convenient cleaning, simple operation, long operation time, low operation cost and the like, and is applicable to the treatment of municipal sewage, industrial wastewater and domestic sewage.
Description
Technical field
The utility model relates to sanitary sewage and Industrial Wastewater Treatment equipment, is the biological respinse sewage disposal device that a kind of activated sludge process combines with microbial film.
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.Membrane bioreactor has following advantage: active sludge biological is very abundant in the membrane bioreactor, is not subjected to the mud expansion effects, and effluent quality is good after treatment, can satisfy the quality of reused water requirement.Because the crown_interception of film can effectively carry out mud-water separation, improve microorganism simultaneously, be specially adapted to the sewage treatment area of middle or small sewage treatment and decentralized treatment of organic matters of organic ability in the sewage.The submerged flat membrane bio-reactor is most widely used a kind of of membrane bioreactor.But flat sheet membrane bioreactor in the market in actual use, still has film contaminated and easy latch up phenomenon easily, and the flux of film is descended, and working cost increases, and has shortened the work-ing life of film.
A kind of flat membrane element structure is arranged in the market, frame, diaphragm supported and the diaphragm composition around this flat membrane element structure comprised, and be provided with curb on the surface that diaphragm supports, because of its curb all adopts laterally or vertically is provided with the rectangle ditch, but no matter be that the water outlet effect of back flushing or curb is still undesirable in actual applications.
Summary of the invention
The purpose of this utility model then is at above-mentioned prior art deficiency, provides that a kind of contamination resistance is stronger, water rate is higher, the novel packaging flat sheet membrane bioreactor that membrane flux is big.
The technical solution adopted in the utility model is as follows:
A kind of novel packaging flat sheet membrane bioreactor, it includes membrane support its feature, in support, be provided with a plurality of flat membrane elements, described flat membrane element includes back up pad and diaphragm, diaphragm arrangement is in the two sides of back up pad, and side is fixed by pressing plate around back up pad and the diaphragm-operated, and the thickness of two side guides is thicker than last press table, top hold-down is provided with suction tube, and the suction tube on a plurality of flat membrane elements all is connected on total water absorption tube.
The two sides of back up pad are evenly distributed with columniform projection in the described flat membrane element.
Described diaphragm is a double-layer structure, and its outer surface layer is the polyvinylidene difluoride (PVDF) material, and its internal layer is the polyester material, is evenly equipped with the pore of 0.08 micron of diameter on the polyvinylidene fluoride layer of diaphragm outside surface.
Do not need to stay again the gap between described a plurality of flat membrane element,, form the aeration passage naturally by its constitutional features between adjacent two flat membrane elements its parallel solid matter setting.
Described membrane support bottom is provided with aeration tube.
The beneficial effects of the utility model have:
Backwash is effective, stain resistance is strong, water rate is high, membrane flux is big, long service life, when operation, can make the membrane bioreactor aeration more abundant, more even, and have and clean characteristics such as convenient, simple to operate, long operational time, working cost are low, be specially adapted to the processing of municipal effluent, trade effluent and sanitary sewage.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross section structure synoptic diagram of the utility model flat membrane element.
Fig. 3 is the structural representation of facing of the utility model flat membrane element.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As Figure 1-3, the utility model agent structure is a membrane support body 7, is provided with a plurality of flat membrane elements in membrane support body 7, and the parallel solid matter setting of a plurality of flat membrane elements forms the aeration passage naturally by its constitutional features between adjacent two flat membrane elements.The utility model flat membrane element includes back up pad 1 and diaphragm 2, diaphragm 2 is located at the two sides of back up pad 1, back up pad 1 is fixed by pressing plate with the side all around of diaphragm 2, and the thickness of two side guides 6 is thicker than last press table, and its thickness difference equals the aeration width of channel.Top hold-down 3 is provided with suction tube 4, is evenly distributed with columniform projection 5 in the two sides of back up pad 1, makes between diaphragm 2 and the back up pad 1 and leaves the space, and these spaces are promptly as the water exit of membrane element.Its top hold-down 3 is provided with suction tube 4, and the suction tube 4 on a plurality of flat membrane elements all is connected to total water absorption tube 8, by total water absorption tube 8 with filtering clear water sucking-off in each flat membrane element.Because what adopted back up pad 1 both sides in the utility model flat membrane element is that circular projection 5 supports diaphragm 2, the water exit that back up pad 1 two sides are formed does not have the dead angle, the resistance of formation suction tube 4 when pump up water reduces relatively, thereby improved the water rate of membrane element.
The utility model is provided with aeration tube 9 in membrane support body 7 bottoms, and aeration tube 9 can arrange according to the intravital diaphragm quantity of membrane support, thereby makes aeration more even, and is more abundant, also accelerated the processing efficiency of sewage simultaneously.In order to strengthen sewage load, a plurality of the utility model can be combined use in addition, be about to the utility model and directly be placed in the activated sludge tank, biological degradation and membrane sepn are combined, can omit second pond like this, reach less investment, floor space is little, the purpose that operating performance is good.
The undeclared part of other that relates in the utility model is same as the prior art.
