Background technology
Membrane bioreactor (Membrane Bioreactor is called for short MBR) is one of novel waste water technology of membrane separation technique and biotechnology combination, also claims the film separated activated sludge method.The efficient cutoff performance that it utilizes membrane separation assemblies carries out solid-liquid separation, has effectively reached the purpose of mud-water separation.The efficient crown_interception of film can the effectively catching nitrifier, and it is trapped in the bio-reactor fully, makes nitration reaction smooth, effectively removes ammonia nitrogen, avoids the loss of mud.Can hold back simultaneously the larger molecular organics that for the moment is difficult to degrade, prolong the residence time of these organism at reactor drum, make it to be decomposed to greatest extent, be one of the most promising wastewater treatment new technology at present.
The major equipment of MBR is a film group device; A large amount of hollow fiber ultrafiltration membrane is installed on the film group device; About the general 2mm of ultra-filtration membrane external diameter, about internal diameter 1mm, the ultra-filtration membrane surface is covered with 0.04 micron aperture; See tubular fibre film silk from the outside just as the fine plastics silk of a rule, tubular fibre is arranged in parallel on the film group device.When operation, film group device is placed in the sewage, clear water is inner to the film silk through micropore permeation from the outside of film silk, and mud is blocked in the outside of film silk.With water pump clear water is drawn into the clean water basin from film group device again.High density mixed solution in the membrane biological reaction pond is through membrane sepn, and pollutent is left in the reaction tank with other mikrobe, and treated water then passes through negative pressure-pumping, qualified discharge.
Specify the structure of the MBR film group device of prior art in conjunction with accompanying drawing 1; As shown in Figure 1, the MBR film group device comprises a counterdie box 1, and water leg 2 is arranged in the counterdie box 1; The two ends of film silk 3 adopt epoxy resin glue 4 to be poured in the plastics bellows 1, and film silk 3 is covered with the hollow-fibre membrane of micropore for the surface.Through the cutting machine cutting, the film silk endoporus that makes epoxy resin build body 4 end faces exposes, and the endoporus that expose the bottom of film silk 3 is communicated with water leg 2, and two ends, counterdie box 1 bottom offer the water outlet 5 that is connected with water leg, water outlet 5 external water absorption tubes.
Owing in use, the situation of the mud of film silk alluvial everywhere difference in the time of the needs cleaning can occurring, needs the situation of all film silks of taking-up, and the film silk does not reach the stage that need take out cleaning but actual meeting sent out existing.
To above-mentioned deficiency, the utility model is proposed.
The utility model content
In view of the problem that exists in the prior art, the purpose of the utility model is to provide the novel detachable curtain type membrane group device that is different from traditional design.
For realizing above-mentioned utility model purpose; The technical scheme that the utility model provides is: a kind of detachable curtain type membrane group device, comprise a counterdie box, and in the counterdie box water leg is arranged; Two ends, counterdie box bottom offer the water outlet that is connected with water leg; The external water absorption tube of water outlet, the counterdie box is provided with plug portion, and plug portion is communicated with water leg; The film silk is assembled bunchy and there is sealing portion at two ends, is provided with the insertion pipe that cooperates with counterdie box plug portion outside the sealing portion.
Described insertion pipe comprises that one holds the cylinder of sealing portion, and cylinder is outward extended with the tube stub that cooperates with plug portion, and hollow via-hole is arranged in the tube stub.
Described tube stub outer wall is provided with sealed groove, is provided with sealing-ring in the sealed groove.
The tube stub of described insertion pipe and plug portion are for being clasped.
The described convexity that is provided with for the tube stub outer wall that is clasped cooperates installation with the draw-in groove that is located at plug portion.
The draw-in groove both sides of said adjacent plug portion are provided with slot.
Be provided with dividing plate between the adjacent plug portion on the described counterdie box.
Described counterdie box is circular sleeve shape or rectangular sleeve tubular.
The beneficial effect of the utility model is: the utility model is different from traditional film silk two ends and is fixed on the design in two bellows; Employing is assembled bunchy with the film silk and is adopted the dismountable structure of plug to be connected on the counterdie box; So can dismantle, clean, replace certain part film silk separately, and need not safeguard whole film group device.
Description of drawings
When combining accompanying drawing to consider; Through with reference to following detailed, can more completely understand the utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide the further understanding to the utility model; Constitute the part of the utility model; Illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model, wherein:
