With people's increasing emphasis on living environment, sewage treatment has been widely used in many fields, such as construction, agriculture, energy and environmental protection, etc. The purified water is discharged to achieve the environmental protection requirement of reasonable discharge. At present, the commonly used sewage treatment process is roughly divided into sedimentation, aeration, regulation tank, biological reactor, circulating pump, membrane assembly, disinfection device, reclaimed water storage tank and reclaimed water system. The sewage treatment process is also a relatively mature treatment process at present, and the sewage treatment effect is good.

[0003] However, in the above treatment process, after the sewage is deposited in the sedimentation tank, a filter is specially arranged in the sedimentation tank to filter the large particle impurities in the sewage, so as to facilitate the subsequent treatment of the sewage.

[0060] In the present embodiment

[0061] The output shaft of the double-shaft air cylinder 39 is in an extended state, and a transparent observation window is arranged on the sedimentation tank 4 to facilitate observation of the highest level of the sediment;

[0062] When the sewage in the sedimentation tank 4 is completely deposited, in order to maximize the discharge of the supernatant, the observation window on the sedimentation tank 4 can be observed. When the highest level of the sediment is observed, a square tube 44 closest to the level and above the level is determined. After determination, the corresponding motor eight is opened, and the output shaft drives the corresponding transmission screw rod two 49 to rotate. Then, by the screw thread cooperation between the transmission screw rod two 49 and the movable plate two 50, the movable plate two 50 and the corresponding link piece 52 are horizontally moved, so that the corresponding blocking plate 46 is horizontally pulled under the driving of the corresponding link rod 47, until the blocking plate 46 is pulled to the rear of the corresponding connecting pipe 45. At this time, a passage is formed between the square tube 44, the connecting pipe 45 and the water guide pipe 6, the supernatant starts to enter from the square tube 44, and finally enters the aeration tank 5 for aeration. After the supernatant is discharged, the threaded cover on the sewage discharge pipe is opened, and the sediment is discharged.

[0063] After the sedimentation tank 4 is used for a period of time, there are many residues attached to the inner wall. In order to quickly scrape off the attached material without the need for traditional manual scraping and cleaning in the sedimentation tank 4, the motor seven is started in the forward direction, and the output shaft drives the corresponding lifting screw rod 41 to rotate. At this time, by the screw thread cooperation between the lifting screw rod 41 and the moving plate 42, the moving plate 42 and the sealing plate 7 are driven downward. During the driving process, when the sealing plate 7 is lowered by a small distance, that is, the distance between the sealing plate 7 and the sewage discharge pipe is sufficient, the output shaft of the double-shaft air cylinder 39 is retracted, so that the blocking plate 40 blocks the gap of the enclosing block 36. At the same time, the scraping ring 37 in the sedimentation tank 4 scrapes the attached material on the inner wall. When the attached material is scraped off, it falls directly onto the sealing plate 7 and is in the enclosing block 36. After the scraping ring 37 is completely removed from the sedimentation tank 4, the motor seven is turned off. At this time, the attached material on the inner wall of the sedimentation tank 4 has been completely scraped off. Then, the staff only needs to scrape the attached material on the sealing plate 7 into the surplus box, so that the quick cleaning work of the attached material on the inner wall of the sedimentation tank 4 is completed, the cleaning and maintenance efficiency is improved, and then the output shaft of the double-shaft air cylinder 39 is extended to lower the blocking plate 40 to the original state. Then, the motor seven is started in the reverse direction to bring the sealing plate 7 and the scraping ring 37 back into the sedimentation tank 4, so that the subsequent sewage treatment work can be continued.

[0068] In this embodiment

[0069] When sewage is aerated in the aeration tank 5, a large amount of foam may be generated in the aeration tank 5 due to aging of activated sludge, sludge age being too high and other problems, and the generation of foam directly causes oxygen to be unable to be transmitted in time, greatly reduces oxygenation capacity and dissolved oxygen content in water, adversely affects microorganisms, and thus the aeration effect of sewage is poor, therefore, a defoaming agent needs to be used to eliminate the foam, and in order to improve the uniformity of the defoaming agent and avoid manual spraying as much as possible, a sufficient amount of the defoaming agent is added into the dosing box 53, and in the process of the rotation of the motor six, the transmission rod 60 is driven to rotate through the meshing between the gear three and the gear four, and then the disc 61 is driven to rotate, and when the disc 61 rotates, the eccentric rod 62 on the disc 61 performs a circular motion with the axis of the transmission rod 60 as the center, and at the same time, the hinged rod 63 connected with the eccentric rod 62 rotates to drive the hinged block 64 and the sliding plate 59 to move linearly and horizontally, and when the sliding plate 59 moves away from the discharge hole 54, the defoaming agent in the dosing box 53 flows into the receiving pipe 55 automatically, and then enters the hollow disc 56 through the hollow column 32, and then drops on the foam in the aeration tank 5 through the plurality of water seepage holes 57, so that rapid defoaming work is formed, and until the sliding plate 59 blocks the discharge hole 54 again, the defoaming agent stops dripping, and until the sliding plate 59 and the discharge hole 54 are separated again, the defoaming agent drips in the aeration tank 5 again, and reciprocates, so that the defoaming agent forms intermittent dripping work, which can prevent the defoaming agent from being consumed too quickly and form good mechanical indirect defoaming work, and the rotation of the transmission rod 60 can follow the rotation of the hollow column 32, and they only need to be rotated by the same motor six, so that the electric energy can be reasonably utilized.
