Abstract
The utility model relates to a carrier biofilm reactor is removed in circulation, including the biofilm reactor body, top -down has set gradually spout hole, inlet tube on the reactor to and the apopore, its characterized in that: the bottom corner of reactor is polygonized structure, and reactor portion is provided with the guide plate, and the aeration pipe upwards extends from the bottom, carries out the aeration to reactor portion and handles, reactor portion is provided with the baffle, and the baffle bottom is provided with the round hole, plays filter effects, and the reactor bottom is provided with the mud pipe that open side down. The utility model has the advantages of: through the forced circulation of guide plate, messenger carrier biofilm reactor is removed in circulation's water conservancy blending compares with general moving bed biofilm reactor and is obviously improved, and circulation, the mixed mass transfer effect of carrier in full pond is better, has the dead angle in the pond hardly.
Description
Technical field
The utility model relates to a kind of circulated moving carrier biofilm reactor.
Background technology
MBBR is the new and effective biomembrance process wastewater treatment equipment of one developed on the basis of biological contact oxidation process and biological fluidized bed in recent years, it had both had traditional biological embrane method anti impulsion load, mud age is long, surplus sludge volume is few feature, had again the high efficiency of activated sludge process and going slick property.Research both domestic and external also proves, MBBR process sanitary sewage, trade effluent and denitrogenation dephosphorizing all have good effect.Due to the restriction of pond type and aerating apparatus, the mobile status of bio-carrier in moving-burden bed reactor is unbalanced, there is dead band to some extent in pond, and mixing mass transfer effect is affected; For ensureing the loopy moving of carrier, required drive consumption is higher, still needs to be improved in hydraulic flow dynamic characteristic and energy consumption.
Summary of the invention
The utility model is in order to solve the problems of the technologies described above, provide a kind of circulated moving carrier biofilm reactor, the technical scheme taked is: comprise biofilm reactor body, reactor is disposed with overflow weir, water inlet pipe from top to bottom, and posticum, it is characterized in that: the bottom comers place of reactor is polygonized structure, and inside reactor is provided with flow deflector, aeration tube upwards extends from bottom, carries out Air Exposure to inside reactor; Inside reactor is provided with dividing plate, is provided with circular hole bottom dividing plate, plays a role in filtering, and reactor bottom is provided with the shore pipe that Open Side Down.
The utility model has the advantage of: by the pump circulation of flow deflector, make the hydraulic flow dynamic characteristic of circulated moving carrier biofilm reactor with general MBBR compare be improved significantly, better, in pond, there is dead angle hardly in the circulation of carrier in full pond, mixing mass transfer effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of circulated moving carrier biofilm reactor, the technical scheme taked is: comprise biofilm reactor body, reactor is disposed with overflow weir 5, water inlet pipe 6 from top to bottom, and posticum 4, the bottom of reactor is Polygons nook is polygonized structure, inside reactor is provided with flow deflector 7, and the flow deflector of reactor plays good guide functions at this, and the flow characteristics that the shape changeable structure at base angle also improves reactor carries out pump circulation.Aeration tube 8 upwards extends from bottom, carries out Air Exposure to inside reactor; Inside reactor is provided with dividing plate 3, be provided with circular hole bottom dividing plate, under the promotion of upstream, filler defines good loopy moving in the reaction zone of reactor, mixed solution flow into settling region, right side from the circular hole 2 bottom dividing plate, and the primary water after precipitation is through the overflow weir overflow water outlet on top.Play a role in filtering, reactor bottom is provided with the shore pipe that Open Side Down.
Open Side Down for shore pipe 1, is conducive to relying on action of gravity to discharge mud, and compared with traditional horizontal shore pipe, spoil disposal efficiency is higher.
At the filler loopy moving ensured in whole reactor with under meeting the aerobic prerequisite of microbial respiratory, gas-water ratio remains on 10:1, and each cycle stability runs 20 days, to ensure to obtain steady result.
After adopting the utility model, when bubble rises at a high speed after air-diffuser release, while being subject to flow shear, clash into carrier surface, make bubbles burst, diameter reduces, and correspondingly increases contact area, also promote the water circulation between support voids in addition, touched more current.Thus, in the operational process of circulated moving carrier biofilm reactor, obviously can compress the thickness of air film and liquid film, increase contact gear ratio surface-area, thus substantially increase the mass transfer velocity of oxygen.
Claims (1)
1. a circulated moving carrier biofilm reactor, comprise biofilm reactor body, reactor is disposed with overflow weir, water inlet pipe from top to bottom, and posticum, it is characterized in that: the bottom comers place of reactor is polygonized structure, inside reactor is provided with flow deflector, and aeration tube upwards extends from bottom, carries out Air Exposure to inside reactor; Inside reactor is provided with dividing plate, is provided with circular hole bottom dividing plate, plays a role in filtering, and reactor bottom is provided with the shore pipe that Open Side Down.
