Abstract
The utility model relates to a non-regurgitant anaerobic aerobic integrated fixed bed biological membrane reactor, and an anaerobic zone, an aerobic zone and a settling zone are connected in series to make up one-piece. The sewage passes an anaerobic membrane bed zone, an aerobic biological membrane zone, the settling zone from bottom to top and finally overflows treating water. The aerobic biological membrane zone adopts suspension type bulking fillers, and the biological membrane floc of the settling zone automatically runs back to a reaction area under the gravity action and forms a vertical internal circulation, without need of a reflux unit. The utility model has simple technological process, quick forming of biological membranes, stable running, short hydraulic detention time, high efficiency, simple and compact device structure and convenient operation and implement, and it can be widely used in sewage treatment work.
Description
Technical field
The utility model relates to a kind of anaerobic aerobic integrated formula static bed biomembrane reactor, is suitable for handling city domestic sewage, biotope sewage and variously contains organic sewage.
Background technology
The biofilm filtration technology in the application in reusing sewage field more and more widely, the food chain classification predation removal effect that this technology makes full use of in the filter tank on the filtrate and filtrate on biomembranous absorption crown_interception, the filtrate oxygenolysis of microorganism in the appended microbial film, form down along current direction and the denitrification of microbial film inside are removed most of materials of failing in the secondary effluent to remove effectively.In the biomembrance process residence time of mud long, the growth of suitable nitrifier, so the biofilm filtration technology can effectively be removed the ammonia nitrogen in the sewage.Utilize the suspending carrier biofilm reactor to remove ammonia nitrogen in the municipal garbage loading embeading percolation liquid as some scholars, can obtain maximum ammonia nitrogen rate of oxidation is 0.6kg/ (m
3D).
The biomembrance process majority that generally adopts both at home and abroad is aerobic form at present, or anaerobic-aerobic bonded form.The anaerobic-aerobic processing waste water that combines, applied range, processing efficiency height, the organic volumetric loading height that can bear.But most of anaerobic-aerobic technologies are two sections splits and reflux are arranged that not only floor space is big, and capital cost and power consumption height, complicated operation, not manageability.Though Chinese patent 97207712 has adopted the integrated flow process of anaerobe oxidation pond, aerobe oxidation pond, inclined-plate clarifying basin, there is the advantage that treatment effect is good, floor space is little, but its structure can cause the water outlet of a part of anaerobe oxidation pond directly to enter inclined-plate clarifying basin without the processing of aerobe oxidation pond, form the short circuit phenomenon of flow process, influence treatment effect.Chinese patent 95236038.1 adopts anaerobic pond, Aerobic Pond, settling tank dephosphorization denitrogenation, and treatment effect is better; But three parts need can be carried out through the transmission of sump pump, and power consumption is big, and floor space is many.U.S. Pat P620578 adopts the technology of preliminary sedimentation tank, anaerobic filter bed, aerobic filter bed, second pond, effluent recycling, and this technology is because employing is split type, and floor space is big, and it is little to handle the water yield, and extra backflow facility has also increased energy consumption.
The utility model content
The purpose of this utility model is to provide a kind of anaerobic aerobic integrated formula static bed biomembrane reactor, special anaerobic film bed, aerobic biologic membrane and subsider are integrated in one, make its compact construction, reasonable in design, avoided the flow process short circuit phenomenon, cone settling tank can effectively flow into aerobic biologic membrane bed district with active sludge certainly simultaneously, need not biomass and biological activity that extra backflow facility also can improve the aerobic biologic membrane district greatly.
The utility model relates to a kind of anaerobic aerobic integrated formula static bed biomembrane reactor that does not have backflow, it is characterized in that in vertical reactor from bottom to up by the special anaerobic film bed district, aerobic biologic membrane district and negative area are composed in series integral type, each district isolates with the porous division board, after sewage is entered by reactor bottom, enter the special anaerobic film bed district through the porous division board, filler A is housed in the special anaerobic film bed district, the porous division board also is equipped with on top in order to fixing filler A in the special anaerobic film bed district, one aeration board is arranged at the top at special anaerobic film bed district upper porous division board, extend the below of aeration board from the outside blast main that inserts of reactor, on aeration board top filler B is housed, form the aerobic biologic membrane district, the porous division board is housed in order to fixing filler B on top, aerobic biologic membrane district, the negative area is a double-barrel structure, and urceolus adopts cone to be connected with the aerobic biologic membrane district, and inner diameter of steel flue is identical with aerobic biologic membrane district diameter, be suspended in the urceolus, the sewage after the processing overflows outside the reactor from the upper end of negative area.Be sewage from bottom to top through the special anaerobic film bed district, aerobic biologic membrane district, negative area, finally overflow treating water, the microbial film flco of negative area flows back to reaction zone automatically under action of gravity, form vertical internal recycle, need not reflux.The special anaerobic film bed district is preferably identical with the internal diameter in aerobic biologic membrane district, the filler of loading in the special anaerobic film bed district is not limited, the filler commonly used for common special anaerobic film bed district gets final product, be preferably the microcellular filler of φ 3～8mm, the filler of loading in the aerobic biologic membrane district is not limited, the filler commonly used for common aerobic biologic membrane district gets final product, and preferably adopts suspension type to fill filler.Air feeds from static bed biomembrane reactor aerobic biologic membrane district bottom, and to have formed the bottom be that flow lifting type anoxic biological filter, middle part are that flow lifting type aerobic biologic membrane fixed bed, top are the device of settling bowl to whole reactor like this.
The utility model technical process is simple, and microbial film forms soon, and is stable, and hydraulic detention time is short, the efficient height, and device structure is simple, compact, and operation is implemented convenient, can widespread use in sewage treatment project.
Description of drawings
Fig. 1 is for using a kind of anaerobic aerobic integrated formula static bed biomembrane reactor of the present utility model, wherein:
I-negative area, II-aerobic biologic membrane district, III-special anaerobic film bed district.1-porous division board, 2-filler A, 3-filler B, 4-inner core, 5-urceolus, 6-blast main, 7-aeration board.
Embodiment
The filler of loading in the special anaerobic film bed district is the microcellular filler of φ 3～8mm, is fixedly filling mode.The aerobic biologic membrane district adopts the bigger suspension type of specific surface area to fill filler.Between anaerobe bed district and aerobic biologic membrane district, isolate less than the porous plate of 3mm with the aperture.Be aeration board on division board, the district provides aeration for aerobic biologic membrane.The negative area is a double-barrel structure, adopt cone to be connected with the aerobic biologic membrane district, inner diameter of steel flue is identical with aerobic biologic membrane district diameter with the special anaerobic film bed district, and the microbial film flco flows back to reaction zone automatically at action of gravity lower edge cone skew wall, form vertical internal recycle, need not reflux.
