Description
Technical field
The invention belongs to water-treatment technology field, especially a kind of fixed bed and moving-bed biofilm composite reaction device.
Background technology
Along with the further raising of sewage drainage standard, traditional biological is processed and is difficult to meet higher water quality standard.Biomembrance process has made up a lot of deficiencies of activated sludge process, as its good stability, bear organic loading and hydraulic loading shock ability strong, without sludge bulking, without refluxing, high to organic clearance, the advantage such as the volume little, sewage work floor space of reactor is little.But biomembrance process also has its distinctive defect, as the filtrate in biological filter easily stops up, needs periodically back flushing, the fixing less stable of competence exertion effect, technique etc. under fluidized state only of the carrier granule in more difficult, the biological fluidized-bed reactor of the replacing of aerator under filler and filler simultaneously.In view of the shortcoming and defect of above technique, MBBR (moving-bed-biofilm-reactor is called for short MBBR) arises at the historic moment.MBBR method was just introduced to some extent and in Europe, is applied very soon at the end of the eighties, and it has been drawn the advantage of traditional activated sludge process and biological contact oxidation process and has become a kind of novel, efficient recombining process treatment process.Its core is exactly to using the floating stuffing that proportion approaches water to be directly added in aeration tank as microbic activity carrier, rely on aeration in aeration tank and current castering action and in fluidized state, when microorganic adhesion is on carrier, floating carrier moves freely along with the convolution inverting action of mixed solution in reactor, thereby reaches the object of sewage disposal.A kind of technique combining as the activated sludge process of suspension growth and the biomembrance process of apposition growth, MBBR method has both advantages concurrently: its only needs the volume of common oxidation pond 20% under identical loading condiction to take up an area few one; Microorganic adhesion with flow, does not need activity sludge reflux or circulation back flushing on carrier; Carrier organism constantly comes off, and avoids stopping up; Organic loading is high, anti impulsion load ability is strong, stable effluent quality; Head loss is little, power consumption is low, and operation is simple, and operational administrative is easy.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of fixed bed and moving-bed biofilm composite reaction device are provided, this device has not only been realized two kinds of biomembranous technology a little, also can improve the processing efficiency of biological treatment, guarantee that the water quality after processing meets new emission standard requirement, when reducing the quantity discharged of sewage disposal after stain thing, the sewage after processing can also be carried out to production reuse.
The present invention solves its technical problem and takes following technical scheme to realize:
And a moving bed biological film device, comprise that urceolus 3, aeration tube 2, aeration plate 5, cylinder shape steel framework 4, Ball-type packing 6 and the elastic filler 7 of reactor forms.Device lower end is connected to water-in 1, upper end is connected to water outlet 8, and steel circular cylindrical framework is fixed on urceolus by reinforcing bar 9, and combined stuffing 7 two ends are separately fixed on a steel or irony cylindrical frame 4, are cylindric arrangement, form an inner core.Urceolus 3 adopts steel or irony cylinder, and there are aeration tube 2 and aeration plate 5 the cylinder end, in the inner core that combined stuffing forms and the annular space between inner/outer tube, is Ball-type packing 6.Because elastic filler has formed one than the boundary of comparatively dense, limited the flow direction in water of Ball-type packing, main body flows along arrow indicated direction.This kind of method increased the filling quantity of filler, and larger specific surface area is provided, and is the biomembranous space that provides larger of adhering to, and also improved the processing efficiency of reactor simultaneously.
And aeration tube and aeration plate are arranged at reactor inner core bottom, for biology provides oxygen, and provide power for the movement of Ball-type packing.
And the floating stuffing proportion in MBBR is close to water.
Advantage of the present invention and positively effect are:
1, the present invention is gathered and is rearranged inner tube wall with elastic filler, substitutes common wall, when playing guide shell effect, has increased reference area, has effectively improved reaction efficiency.
2, the present invention is the combination of static bed biomembrane reactor and MBBR, has given full play to the advantage of static bed biomembrane, has also brought into play the advantage of the initiative of moving-bed biofilm simultaneously.
Accompanying drawing explanation
Fig. 1 is waste disposal plant schematic diagram of the present invention and sectional view;
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
Device selects steel or synthetic glass cylinder as the urceolus of reactor, places with one heart a steel cylindrical frame in cylinder, and elastic filler is fixed on cylindrical frame, and elastic filler is gathered and rearranged inner tube wall, substitutes common wall, plays guide shell effect.
Aeration tube and aeration plate are arranged in reaction unit bottom, for biology provides oxygen, and provide power for the movement of Ball-type packing.Ball-type packing is placed in reactor, under aeration flow action along the direction of arrow when inner core rises to inner core top, along annular space between urceolus and inner core, decline again.Ball-type packing surface is covered with microbial film, by the migration of filler, and the microbial film on filler is fully contacted with waste water, thereby has improved processing efficiency.
Spherical proportion, is added in combined reactor as microbic activity carrier close to the floating stuffing of water, relies on the castering action of aeration and current, make carrier in suspending and fluidized state, can be comprehensive freely movable, do not need to fix, only need hold back net in water outlet setting.Active carrier is by polypropylene material cast molding, has corrosion resistant, feature that intensity is high.The filler adding in carrier is porous and granular filtrate, and its major ingredient is tens kinds of mineral substance such as silicon, aluminium, calcium, sodium, magnesium, titanium, manganese, iron, nickel, cobalt and molybdenum and trace element, and apparent is irregular particle, and color is chocolate, porous light weight; In filler, the proportioning of each composition need be according to the feature of waste water quality, high efficiency composition flora, through overtesting, determine, not only to improve the volume of holding (so that the removal efficiency such as COD, ammonia nitrogen are more than 90%) that keeps microorganism on carrier, prevent again microorganism rapid growth and cause obstruction.
The working process of apparatus of the present invention:
By pump, waste water pump is entered to reactor, open gas blower, air enters reactor, and aeration tube and aeration plate are arranged in reaction unit bottom, for biology provides oxygen, and provides power for the movement of Ball-type packing.Ball-type packing is placed in reactor, under aeration flow action along the direction of arrow when inner core rises to inner core top, along annular space between urceolus and inner core, decline again.Ball-type packing surface is covered with microbial film, by the migration of filler, and the microbial film on filler is fully contacted with waste water.Waste water contacts with moving-bed biofilm with static bed biomembrane after import enters reactor, realizes the removal of pollutent.Two kinds of biomembranous advantages that reactor of the present invention is integrated, have also avoided shortcoming separately simultaneously, make processing efficiency improve 35-40%.
