Brief description of the drawings
Fig. 1 is the structural representation of the utility model expanded bed bioreactor.
In accompanying drawing, the list of parts representated by each label is as follows：
301st, hollow body, 302, annular water distribution module, 303, roof, 304, circuit, the 305, second water inlet, 306, ring
Shape gap, 307, water conservancy diversion vertebra, 308, biologic packing material layer, the 309, second delivery port.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that retouched
The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.
The utility model embodiment discloses a kind of expanded bed bioreactor, is mainly used in fish and vegetable symbiotic system, circulation
The purification of water quality of water cultivating system and sewage disposal system.As shown in figure 1, during expanded bed biological respinse implement body can include
Empty body 301 and the annular water distribution module 302 for being arranged on the upper end of hollow body 301, wherein, annular water distribution module 302 includes top
Wall 303 and the circuit 304 for prolonging the setting of the edge of roof 303, are provided with the second water inlet 305 on circuit 304, circuit 304 with it is hollow
Annulus 306 is formed between body 301, is provided with roof 303 in water conservancy diversion vertebra 307, hollow body 301 and is additionally provided with life
Thing packing layer 308, the second delivery port 309 is provided with the bottom of hollow body 301.
The operation principle of biofilter is in the utility model：Pressurization sewage is pumped into the second water inlet by water pump, passes through
Inside reactor is entered by annulus after circuit is uniform, under the current direction that homogeneous flow velocity is formed under the synergy of water conservancy diversion vertebra
Flowing.Its downward pressure is approximately equal to the buoyancy of biologic packing material layer so that biologic packing material starts expansion, forms expanded bed, and protect
Certain expansion rate is held, to control packing layer lower boundary to be higher than delivery port, prevents filler to be lost in, by being attached to filler surface
After microorganism decomposition absorbs, sewage is purified, from the outflow of the second delivery port.
Specifically, circuit interior angle does fillet processing, so as to reduce the loss of flood peak；Biologic packing material layer has certain density
And buoyancy, specifically can using proportion be less than water particle carry out filler, its a diameter of 0.001mm~10mm, its expansion rate can
To reach 20%~200%, such as using polyurethane closed-cell foam particle, polystyrene foaming granule or PP expanded beads, phase
Than the sand filler of equal expansion rate, its light weight, resistance are low, operating head polishing loss is small.Because filler is in swelling state, fill out
Keep certain gap between material particle, form big voidage, thus to a certain extent the growing space of increase bacterium with
And the contact area with sewage, so as to provide good growing environment for bacterium, be conducive to the amount reproduction of bacterium.
Bacterium decomposes the nutriment of water body, while generating biomembrane, when biomembrane hyperplasia, inner side biomembrane is in
Anaerobism, biomembrane adhesive force reduction, comes off naturally under the turbulent shear of water, and the filler after coming off regrows biomembrane, shape
Renewal into biomembrane, come off, so that biomembrane is abundant, easily by filtering or precipitation power is removed.
Filler particles keep the dispersity of geo-stationary in the presence of waterpower, and every filler is in certain Space Rotating
Reciprocating motion does not result in strong friction, so as to be conducive to the attachment and renewal of biomembrane；Due to water (flow) direction and filler
Movement tendency on the contrary, so filler particles kept in certain scope of activities rotate and move back and forth, add higher water
Flow velocity degree so that filler surface Reynolds number is high, liquid level renewal speed is fast, so as to being the more oxygen of biological film zone and bottom
Thing, its biofilm is stable, reaction rate is high.
Because filler particles are in swelling state, internal voids are big, therefore the solid such as suspension can pass freely through filler
Layer, will not result in blockage in filler inner accumulation, without clean and maintenance.
Expanded bed bioreactor in the utility model embodiment uses biologic packing material, and its surface area is big, biological affine
Property it is good, have the advantages that biofilm is stable, reaction rate is high, so that treatment effeciency is high, effluent quality is good.With fixed bed biological respinse
Device compares, and expanded bed bioreactor of the present utility model has small volume, efficiency high, good processed water quality, cost low, certainly clear
Wash, without block the advantages of；Compared with moving-bed bioreactor, with small volume, efficiency high, hydraulic detention time be short, cost
Low advantage；Compared with fluidized bed aerosol generator, with the loss of flood peak is small, energy consumption is low, easy biofilm, bioactivity high, fill out
The advantages of material is not easily runed off；Compared with high-loading logical filter, with small volume, treatment effeciency is high, water quality is good, cost is low, heat
The advantages of loss small, low temperature season efficiency high.
Finally it should be noted that：Various embodiments above is only limited to illustrate the technical solution of the utility model, rather than to it
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
