The working principle is as follows:

firstly, when in use, sewage is firstly introduced into the aeration tank main body 1, then activated sludge is added, then the first opening and closing valve 76 is closed, the second opening and closing valve 77 is opened, the air blower pipeline 5 intensively supplies air to the connecting pipeline 4, then the air blower 6 is opened to input air into the air blower pipeline 5, then the air in the air blower pipeline 5 is input into the aeration pipeline 2 through the connecting pipeline 4, finally the aeration pipeline 2 discharges the air from the water bottom through the aeration head 3, so that dense bubbles are generated in the water, oxygen can be better dissolved into the water, the concentration of dissolved oxygen is improved, and the purpose of promoting aerobic microorganisms to degrade organic matters is achieved.

Secondly, in the process of sewage treatment, sewage treatment chemicals are usually required to be added into the aeration tank main body 1 to adjust the pH value of the sewage in the aeration tank main body 1, or nutritional chemicals such as urea are required to be added to keep the activity of sludge, when the chemicals are added, the first open-close valve 76 is opened, the second open-close valve 77 is closed, the air blower pipeline 5 supplies air to the discharging pipeline 71 in a centralized manner, then the chemicals are added into the discharging pipeline 73, the chemicals are supplemented into the discharging pipeline 72 by the discharging pipeline 73, the chemicals can be prevented from reversely flowing out of the discharging pipeline 71 into the air blower pipeline 5 by arranging the filter screen 78 on the inner side of the discharging pipeline 71, the bin door 74 is covered on the discharging pipeline 73 to close the same, then the air blower 6 is opened, and the air in the discharging pipeline 5 is input into the discharging pipeline 72 by the discharging pipeline 71, meanwhile, the medicament in the blanking pipeline 71 is pushed into the discharging pipeline 72 under the pushing action of air, at the moment, the air pressure borne by the piston 754 is greater than the elastic acting force of the return spring 755, so that the piston 754 can overcome the elasticity of the return spring 755 and move, the piston 754 drives the sleeve 752 to slide out of the surface of the discharging pipeline 72 through the connecting rod 753, the feed port 751 is in an open state at the moment, the medicament can be discharged to the bottom of water through the feed port 751, in the aeration process, the upwardly floating bubbles can drive the medicament to rise to the water surface from the bottom of water, so that a better fusion effect is achieved, the medicament can be more easily diffused to the whole aeration tank main body 1 when being thrown from the middle part of the aeration tank main body 1, the medicament is guaranteed to be uniformly thrown, the repeated throwing operation of workers is not needed, and the labor amount of medicament throwing work is reduced.

Thirdly, after the medicine is put in, the first open/close valve 76 is closed to stop inputting air into the discharge pipe 72, and after the piston 754 loses the acting force on the piston 754, the piston 754 can move and reset under the elastic force of the return deformation of the return spring 755, and simultaneously the piston 754 drives the sleeve 752 to be sleeved back on the surface of the discharge pipe 72 through the connecting rod 753, so that the feed opening 751 is closed, and the floccule in the sewage is prevented from entering the feed opening 751 to cause the blockage of the discharge pipe 72.

The utility model provides a sewage treatment aeration tank, throw material device 7 through having set up the high efficiency on air blower pipeline 5, through adding the medicament in feed bin 73 down, later open air-blower 6, make the medicament discharge the underwater through dog-house 751, in aeration process like this, the bubble that upwards floats can drive the medicament and rise to the surface of water from the submarine, in order to reach better integration effect, and the medicament drops into from the middle part of aeration tank main part 1 and can more easily spread whole aeration tank main part 1, guarantee that the medicament is put in evenly, do not need the staff repeated operation of puting in, the amount of labour of medicament input work has been reduced, through having set up automatic sealing structure 75 at the end of arranging material pipeline 72, after the medicament is put in, close first on-off valve 76 and stop to arrange material pipeline 72 input air, make the piston 754 resume the elastic force of deformation under reset spring 755 and move and reset, piston 754 orders about the surface of sleeve 752 cover back row material pipeline 72 through connecting rod 753, and then seal the dog-house, avoid causing the flocculent in the sewage to get into the dog-house 751 that flocculent pipe 751 stops up the jam of material pipeline 751 72.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof.
