Referring to fig. 1 and fig. 2, a closed defoaming device for a foam pool of a biochemical system in this embodiment includes: hoisting shed 9, aerobic tank 4 and running water pipeline 1; the aerobic pool 4 is arranged in the hoisting shed 9, the roof of the hoisting shed 9 is provided with a plurality of branch pipelines which are uniformly arranged, the branch pipelines are provided with spray heads 10, the spray heads 10 are uniformly arranged along the length direction of the branch pipelines, and the spray heads 10 extend into the hoisting shed 9; the tap water pipeline 1 is communicated with the branch pipeline, and a first valve 5 is arranged between the tap water pipeline 1 and the branch pipeline.

Compared with the prior art, the defoaming device is sealed in biochemical system foam tank of this scheme, seal good oxygen pond 4 in hoist and mount canopy 9, and a plurality of lateral conduits of installing evenly distributed at the canopy top, carry the running water in to the lateral conduit, install shower nozzle 10 on the lateral conduit, seal good oxygen pond 4 in hoist and mount canopy 9, the air that produces after making good oxygen pond 4 interior microbial reaction seals in hoist and mount canopy 9, reduce its contact with oxygen, and adopt shower nozzle 10 to spray the foam surface in good oxygen pond 4 with water, hit garrulous mode through physics and eliminate surface of water foam, the excessive problem of foam in good oxygen pond 4 has effectively been solved, the temperature in the pond has also been reduced in effect.

In the scheme, the aerobic tank 4 is sealed in the hoisting shed 9, so that the worker can walk and overhaul on the top surface of the hoisting shed 9. On hoist and mount canopy 9, the branch pipeline divide into two or the multichannel, then is provided with the shower nozzle 10 of certain angle on every pipeline and stretches into in the canopy, and the branch pipeline utilizes the atomizer to take the pressure water atomizing, and the design of shower nozzle 10 and branch pipeline is fit for reason and is arranged as the overall arrangement according to the size of the good oxygen pond 4 in the in-service use to guarantee that the coverage area is comprehensive.

As shown in fig. 1, the device further comprises an antifoaming agent pipeline 2, the antifoaming agent pipeline 2 is communicated with the branch pipeline, and a second valve 6 is arranged between the antifoaming agent pipeline 2 and the branch pipeline.

In this scheme, can supply the defoaming agent to the lateral conduit alone, also can supply tap water and defoaming agent simultaneously, the pipeline of selecting for use is confirmed according to how much of the good oxygen pond 4 surface foam of actual production in-process to carry out the control of switch through first valve 5 and second valve 6 to tap water pipeline 1 and defoaming agent pipeline 2 respectively.

As shown in fig. 1, the defoaming agent pipeline 2 is further communicated with the tap water pipeline 1, and a fourth valve 11 is disposed between the defoaming agent pipeline 2 and the tap water pipeline 1.

The defoaming agent pipeline 2 is communicated with the tap water pipeline 1, and the amount of tap water entering the defoaming agent pipeline 2 in the tap water pipeline 1 is controlled through the fourth valve 11, so that the defoaming agent is conveniently prepared.

As shown in fig. 1, the system further comprises a treated biochemical water pipeline 3, the treated biochemical water pipeline 3 is communicated with the branch pipeline, and a third valve 7 is arranged between the treated biochemical water pipeline 3 and the tap water pipeline 1.

In this scheme, increase the biochemical water pipeline 3 after the processing all the way to control it through third valve 7, carry out special treatment with biochemical water, get rid of the surface active substance of aquatic, then carry out reuse, eliminated the foam in the good oxygen pond 4 promptly, still carried out reuse to sewage, practiced thrift the water resource to a certain extent, reduced the sewage treatment cost. When too much foam is in the aerobic tank 4, the treated biochemical water pipeline 3, the defoaming agent pipeline 2 and the tap water pipeline 1 can be opened at the same time.

As shown in fig. 1, the treated biochemical water line 3 and the defoaming agent line 2 supply liquid into the branch lines by a pump 8.

The liquid in the biochemical water pipeline 3 and the defoaming agent pipeline 2 after treatment is extracted through the pump 8, the water pressure in the pipelines is ensured to be constant and maintained at about 0.3 Mpa, the coverage range of the water sprayed out of the spray head 10 or the defoaming agent is further ensured to be wider, and the better foam on the surface of the aerobic pool 4 is eliminated. In addition, the material of pipeline all adopts the PPR material in this scheme, because the PPR material has certain corrosion resistance, and the quality is light. Since the water pressure in the tap water pipeline 1 can effectively ensure that the water pressure is enough, the pump 8 is not used for pumping.

As shown in figure 2, the height of the aerobic tank 4 from the ceiling of the hoisting shed 9 is not more than 2 m.

The height between the aerobic tank 4 and the ceiling of the hoisting shed 9 is set to be not more than 2m, so that the distance between the spray head 10 and the surface of the aerobic tank can be ensured within the range that the spray head 10 can spray.

The spray head 10 is preferably a spiral spray head. Because spiral nozzle sprays the scope for extensively, and be difficult to blockked up, consequently, the preferred spiral nozzle that just adopts the spiral nozzle of PVC material of shower nozzle 10 in this scheme, avoids being corroded by chemical reagent.

As a further development of the solution, the defoamer pipe 2 is connected to the tap water pipe 1 from the dosing tank. Install the liquid level induction meter in the bottom of jar of dispensing, set up second valve 6 into the solenoid valve, be connected solenoid valve and induction meter electricity, when liquid level induction meter sensed when the water level in the jar of dispensing reduces to setting for the high position promptly when water is short of using up, can transmit signal for the solenoid valve, the solenoid valve is closed after receiving the signal, rivers in the defoaming agent pipeline 2 stop. And the dispensing tank lateral wall installation siren at, with siren and liquid level induction meter intercommunication, when liquid level induction meter sensed the water level in the dispensing tank and reduced to setting for the high position, the solenoid valve was closed, and the siren sounds simultaneously, informs the staff in time to add water or overhaul.
