Step improves effluent quality.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the embodiment of the present invention 1；
Fig. 2 is the structural schematic diagram of the embodiment of the present invention 2；
Fig. 3 is the structural schematic diagram of ball-shaped filling material.
Specific implementation mode
Below with reference to attached drawing, the present invention is described in detail.
Embodiment 1
Such as Fig. 1, the sewage disposal device of the application, including be sequentially communicated water inlet 1, aerobic area 2, aerobic zone 3, precipitation
Area 4, sterile zones 5 and water outlet 6.
For the water inlet close to aerobic area top layout, water inlet is provided with filter 8, and filter selects basket filtering
Device, filter can filter out the large particulate matter contained in sewage, avoid equipment dirt and block up, alleviate deposition situation.
The aerobic area is connected to extraneous aerating system, ball-shaped filling material 7 is filled in aerobic area, ball-shaped filling material includes ball-type
Rack 71 and the sponge 72 being filled in ball type network frame, this structural configuration optimization enrich microbe species and quantity, promote
Mass-transfer efficiency between gas-liquid-solid three-phase substance accelerates the degradation rate of water pollutant.Filling sponge is that one kind is more
Hole elastic material and a kind of main body framework reticular structure have good water imbibition, excellent gas permeability and higher machinery
Intensity, material price are low in cost and easily available.Ball type network frame mesh size and sponge shape can be adjusted according to applicable sewage disposal feature
It is whole, to ensure the effect of good water project situation and anti-shock loading.In use, the ball-shaped filling material is placed directly within aerobic area
In, it is in suspension flow regime in pond, sewage, air can be made and be grown on the biomembrane on filler surface contacted, promotes
Biomembrane fast-growth completes " biofilm ", solves the problems, such as that other fillers " biofilm " are difficult, microorganism concn is higher in pond, favorably
In keeping good bioactivity, volumetric loading is improved.Ball-shaped filling material is filled in aerobic area, to inside energy outside it when aeration
Anoxic zone and anaerobic zone are formed, is conducive to denitrogenation dephosphorizing, and it is not necessary that anaerobic zone is separately provided, reduce equipment volume.
The aerobic zone mixed-liquor return is to aerobic area；The regular spoil disposal in settling zone, settling zone top are provided with electrochemistry and remove
Phosphorus device 9 enhances phosphor-removing effect to combine electrochemistry dephosphorization and biological phosphate-eliminating, it is ensured that water outlet TP emission compliances.
The sterile zones front end is provided with filter bag 10, and sterile zones rear end is provided with ultraviolet germicidal lamp tube 11；Filter bag is not only
The pollution of ultraviolet germicidal lamp tube is alleviated, and has filtered out the SS in water outlet, further improves effluent quality.
Embodiment 2
