Further, the cell body inwall on described infundibulate deflector top is provided with annular water distributor；The sewage that water inlet pipe flows out can be evenly distributed in the upper brim edge of whole cell body by annular water distributor so that current can flow on infundibulate deflector with minimum water layer thickness, it is to avoid current fall into from one side and reduce aeration efficiency infundibulate deflector.
Further, described annular water distributor is provided with outlet；It is mixed uniform sewage to fall into infundibulate deflector from outlet.
Further, described infundibulate deflector bottom is provided with cone and strikes waters plate；The sewage fallen from infundibulate deflector end opening directly impacts the top of plate of striking waters at cone, spray of water or formation turbulent flow whirlpool, further increase the content of oxygen in water, aeration is carried out by the action of gravity of water body self, decrease energy resource consumption, decrease later stage operation and maintenance cost.
Further, described cone plate top of striking waters is provided with ceramic tile；The bonding area of ceramic tile is struck waters the projected area on plate at cone more than infundibulate deflector end opening, so can ensure that sewage is ceramic tile entirely when infundibulate deflector end opening falls and the contact surface of conical plate of striking waters, add service life of equipment, reduce sewage for the corrosion of equipment and impact loss, decrease mud and strike waters the adhesion amount on plate at cone.
Further, described cone plate bottom of striking waters is provided with grid layer；Grid layer is circular cone structure, and sewage is filtering subsequently into next step purification process through grid layer after infundibulate deflector falls.
Further, described cell body bottom is provided with packing layer.
Further；It is provided with floating filler in described packing layer；Floating filler is spherical structure, external structure material is polypropylene, inner core is ceramic packing, floating filler acts primarily as the effect of biofilm carrier, have the effect retaining float concurrently simultaneously, there is biological attachment power strong, specific surface area is big, porosity is high, chemistry and biological stability are good, durable in use, not dissolution nuisance, do not cause secondary pollution, anti-ultraviolet, aging resistance, the features such as hydrophilicity is strong, in use, microorganism easily generates, easily change, acid and alkali-resistance, aging resistance, not by water currents, service life is long, excess sludge is few, easy for installation.
Further, described packing layer outer wall top is provided with outlet pipe.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) this apparatus structure is compact, and floor space is less.
(2) this device utilizes water body self gravitation effect to carry out aeration, reduces aeration energy consumption, decreases equipment operation and maintenance cost, adds aeration efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein 1 cell body；2 infundibulate deflectors；3 annular water distributors；4 outlets；5 cones are struck waters plate；6 ceramic tiles；7 grid layers；8 packing layers；9 floating fillers；10 outlet pipes.
