In pond 6.
As shown in Fig. 2, being remained to be further reduced foam on scraping bubble plate 61, bubble plate 61 is being scraped in inverted V type, is scraping bubble plate
61 include the left scraper plates 611 and right scraper plate 612 that are obliquely installed, the angle between left scraper plate 611 and right scraper plate 612 be 60 ° extremely
120°.Preferably, the angle in the present embodiment between left scraper plate 611 and right scraper plate 612 is 90 °, left scraper plate 611 and right scraper plate
612 are obliquely installed the contact area that can either increase itself and foam, and can play guiding function to foam, and foam is made to be easier to pass through
Foam outlet 67 enters blebbing pipeline 671.
As shown in Figure 1 and Figure 5, the lower end of left scraper plate 611 and right scraper plate 612 is equipped with defoaming part 614, and defoaming part 614 is
One of which in wire brush, soft ribbon or filiform.Defoaming part 614 can scrape bubble plate 61 sliding scrape bubble when, steel
Wire brush pokes part foam, reduces total foam volume, soft ribbon and filiform as far as possible, part foam can be made to be attached to
Above, when moving to foam outlet 67, under the spray effect of spray assemblies 66, aerobic tank 6 is discharged in foam, is reduced aerobic
Foam in pond 6 enables aerobic tank 6 to dissolve sufficient oxygen.
As shown in Figure 1, the two sides that left scraper plate 611 and right scraper plate 612 are away from each other are respectively equipped with several antifoam meters 615.Defoaming
Needle 615 can as much as possible poke foam in the moving process for scraping bubble plate 61, the foam being further reduced in aerobic tank 6,
Aerobic tank 6 is set to dissolve sufficient oxygen.
As shown in Figure 1, foam can be aerobic if operator is not purged the foam in aerobic tank 6 in time
6 ullage of pond accumulation, when the foam in aerobic tank 6 is excessive, scrape bubble plate 61 scrape bubble effect can be deteriorated, therefore, in left side
Spray general pipeline 661 has upwardly extended outlet pipe 663, and outlet pipe 663 is equipped with opening and closing valve 6631.Outlet pipe 663 is total far from spray
One end of pipe 661 is communicated with spray head 664, and spray head 664 is equipped with several spray nozzles 6641.Open opening and closing valve 6631, spray
First 664 spray foam by spray nozzle 6641, reduce foam sharply, and subsequent bubble plate 61 of scraping is facilitated to scrape foam
It removes.
Specific implementation process:
City domestic sewage in cesspool 1 is successively through primary sedimentation tank 2, the first filtering ponds 3, anaerobic pond 4, anoxic pond 5, aerobic
Pond 6, biofilm filtration pond 8, is filtered secondary settling tank 7, and sterilized pond 9 carries out disinfection to filtered city domestic sewage
After be emitted into tank 10.
Foam can be generated in aerobic tank work, foam moves upwards, and wears when larger-diameter foam moves upwards
When crossing defoaming net 65, since the diameter of foam is greater than the aperture of defoaming net 65, foam will be swarmed in by defoaming net 65, to reduce
Part foam in aerobic tank 6.
The rotor rotation of motor 621 drives drive sprocket 622 to rotate, and driven sprocket 623 passes through the transmission effect of chain 64
As drive sprocket 622 rotates, drive block 641 can move together with chain 64 at this time.By the transmission of drive block 641, pass
Motion block 641 can carry out sliding, guide housing 613 up and down in guide housing 613 can also carry out left and right cunning under the drive of drive block 641
It moves, makees straight reciprocating motion to realize and scrape bubble plate 61, drive defoaming part 614 and defoaming stick to make straight reciprocating motion, disappear in time
Except the foam on 6 liquid level of aerobic tank, contact oxygen contained in air with liquid level as far as possible, to keep aerobic tank 6 molten
Sufficient oxygen is solved, sewage heat dissipation and microbial reproduction in aerobic tank 6 are conducive to.
When scraping the position steeped plate 61 and move to foam outlet 67, spray assemblies 66 are opened, and spray is in charge of 662 through faucet
It scrapes bubble plate 61 for 6621 pairs to spray, the foam scraped on bubble plate 61 is made to be not easy to remain in aerobic tank 6.
When the foam in aerobic tank 6 is excessive, opening and closing valve 6631 is opened, spray head 664 is by spray nozzle 6641 to foam
It is sprayed, after reducing foam sharply, defoaming mechanism works, and operating procedure is as described above.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
