It should be noted that the aperture of the air vent 15 is small, and the amount of gas required for the air vent 15 entering the chute 16 to push the rack 17 to move back and forth is large, so that the time for the air to push the rack 17 to move back and forth is long, and the speed of the cylindrical plug 11 rotating back and forth is slow;

further, when the cylindrical plug 11 rotates back and forth, the position of the vent 12 on the cylindrical plug 11 changes, so that the following changes occur:

the air vent 12 leads one of the aeration pipes 2 to be communicated with the air inlet hole 9 (as shown in the state of (r) in fig. 7);

the vent 12 leads the two aeration pipes 2 to be communicated with the air inlet 9 (as shown in the state II in the figure 7);

the vent 12 leads the other aeration pipe 2 to be communicated with the air inlet 9 (as shown in the state of the third part in the figure 7);

the vent 12 is restored to the original position (the state of r in fig. 7).

Therefore, the frequency of the change of the aeration pipe is slower, and the slower change of the aeration pipe can give enough time for the microbial colony to move to the water area with oxygen.

In summary, the position of the air outlet area in the tank body 1 is changed slowly, so that the aerobic microorganisms can have enough time to migrate.

The driving mechanism comprises a rack 17 which is connected in a sliding way in a sealing way in the sliding groove 16, the rack 17 is elastically connected on the inner wall of the sliding groove 16 through a spring 22, a sealing plate which is connected in the sliding way 16 in a sliding way in a sealing way is arranged at the end part of the rack 17 and used for ensuring the sealing property, a first through hole 19 communicated with the sliding groove 16 is arranged on the side wall of the tank body 1, a second through hole 23 communicated with the circular groove 10 is arranged on the side wall of the tank body 1, a gear 18 meshed with the rack 17 is rotatably connected at the inner top part of the sliding groove 16, the gear 18 is coaxially and fixedly connected with the cylindrical plug 11, a square groove 20 is arranged on the side wall of the tank body 1, a transmission mechanism is arranged on the inner wall of the square groove 20, the cylindrical plug 11 is in transmission connection with the stainless steel pipe 3 through the transmission mechanism, the transmission mechanism comprises a first, and the first bevel gear 7 is coaxially and fixedly connected with the cylindrical plug 11, and the second bevel gear 21 is coaxially and fixedly connected with the stainless steel pipe 3.

The device can adopt the air pump of continuation air feed, need not to set up relevant automatically controlled subassembly and control air pump intermittent type nature air feed, adopts pure mechanical parts, has improved the life of equipment, and manufacturing cost is lower.

Compared with the traditional method of putting a large amount of microorganisms into the sewage to treat the sewage, the method can also avoid the phenomenon that the microorganisms are excessively put into the sewage and die due to insufficient oxygen in the water, reduces the burden of equipment and the input amount of the microorganisms compared with the method of putting a large amount of microorganisms into the sewage, is more favorable for saving the cost, can enable the flora to move in the sewage tank by adopting a regional oxygen supply mode, and improves the activity of the microorganisms.

In the invention, water in the tank body 1 flows into the stainless steel pipe 3 from the water inlet 5, the slide block 4 is pushed to the inner bottom of the stainless steel pipe 3, and when high-speed and high-pressure gas is introduced into the gas inlet 9, the gas flows into the two aeration pipes 2 from the gas vent 12 and supplies gas into the tank body 1 from the gas outlet 8.

Part of gas flows into the sliding chute 16 through the gas guide hole 15, so that the pressure in the sliding chute 16 is gradually increased, and further the rack 17 in the sliding chute 16 can be pushed to move, when the rack 17 is pushed away from the first through hole 19, the gas escapes from the first through hole 19, the pressure in the sliding chute 16 is reduced, the spring instantly pushes the rack 17 to reset and block the first through hole 19 again, and the pressure in the sliding chute 16 starts to be gradually increased, so that the rack 17 can push the gear 18 to rotate back and forth, so that the cylindrical plug 11 coaxially arranged with the gear 18 also rotates back and forth, so that the vent 12 on the cylindrical plug 11 intermittently conducts the channel 14 with the gas inlet 9, and the gas can be intermittently supplied to the stainless steel pipe 3.

When the vent 12 on the cylindrical plug 11 is communicated with the channel 14, the gas can push the sliding block 4 to move upwards when flowing into the stainless steel pipe 3, the water in the stainless steel pipe 3 is sprayed out by the spraying pipe 6 and sprayed on the water surface, thereby spraying water and defoaming, when the strip-shaped groove 13 on the cylindrical plug 11 is communicated with the channel 14, the water flows into the stainless steel pipe 3 again and pushes the sliding block 4 to the inner bottom of the stainless steel pipe 3 again, therefore, the device can be recycled.

In the back-and-forth rotation process of the cylindrical plug 11, the stainless steel pipe 3 can also rotate back and forth under the linkage of the first bevel gear 7 and the second bevel gear 21, and the spray pipe 6 at the upper end of the stainless steel pipe 3 can stir the water surface and break up foam on the water surface.

When different aeration pipes 2 and inlet port 9 communicate, can change the position of giving vent to anger in the cell body 1 for the region that the oxygen content is high in the cell body 1 also changes thereupon, and aerobic form microbial species changes and moves thereupon along with the region of oxygen enrichment in the cell body 1, thereby can improve the energy consumption of microorganism self, need decompose more pollutants and come to provide energy for self, thereby improve the decomposition rate to pollutant in the sewage.
