The L-shaped plate controls the jet piston cylinder to perform piston jetting through the jet piston rod. The driving plate pushes the push block through the connecting frame to clean the suspended matter on the surface of the fixed suspension frame, which not only prevents the suspended matter in the sewage from sinking to the bottom, but also ensures that there is sufficient dissolved oxygen in the sewage, further oxidizes and decomposes the organic matter in the sewage, and keeps the sediment in a suspended state.

[0017] 2. The present invention filters suspended matter by setting a filtering mechanism. The connecting plate drives the filter plate to move synchronously while performing left and right reciprocating motion. When the filter plate moves to the outside of the reactor, the cleaning mechanism cleans the sediment filtered by the filter plate to prevent the sediment from accumulating and causing blockage, thereby improving the harmlessness index of sewage treatment and reducing the cleaning burden of the staff.

[0018] 3. While the cleaning mechanism is cleaning the sediment filtered out by the filtering mechanism, the cleaning roller is cleaning and unblocking the mesh of the filter plate. At this time, the nozzle sprays the flocculant to the contact position between the cleaning roller and the filter plate, thereby improving the cleaning effect of the cleaning roller on the filter plate and fully adding the flocculant to the surface of the filter plate, so that the cleaned filter plate moves to the left to the inside of the reactor. When the filter plate with the flocculant moves into the reactor, the reaction of the sediment in the sewage is accelerated, thereby further improving the filtering of the sewage, so that the present invention can continuously and efficiently perform sewage treatment when cleaning the sediment, and ensure the continuity of the device when removing the separated sediment.

[0028] A wastewater treatment process based on microbial induction comprises the following steps: Step A: Pour the sewage to be treated into the reactor 1, the aeration mechanism 100 aerates the sewage in the reactor 1, and the impurity removal mechanism 200 removes the suspended matter generated in the mixing reaction process of the sewage; Step B: The filtering mechanism 300 filters the mixed reaction sewage; Step C: The cleaning mechanism 400 cleans the sediment filtered by the filtering mechanism 300, and the cleaning mechanism 500 clears the mesh on the surface of the filter plate 304 while intermittently adding flocculants.

When the cleaning roller 504 rotates, the mesh of the filter plate 304 is cleaned. At this time, the nozzle 506 sprays flocculant to the contact position between the cleaning roller 504 and the filter plate 304, thereby improving the cleaning effect of the cleaning roller 504 on the filter plate 304 and fully adding the flocculant to the surface of the filter plate 304, thereby improving the filtering work of the filter plate 304 on the sewage in the reactor 1.

[0030] Working principle: After the sewage treatment device is installed, the sewage to be treated is poured into the reactor 1, and the control switch is turned on. The output end of the first motor 10 drives the driving shaft 14 fixedly connected thereto to rotate, and the driving shaft 14 drives the driving cam 101 and the stirring blade 15 fixedly connected thereto to rotate, and the stirring blade 15 rotates to stir the sewage in the reactor 1; When the driving cam 101 rotates, the cam groove 102 pulls the left hinge shaft 202 and the right hinge shaft 104 to perform alternating left-right reciprocating motions, and the right hinge shaft 104 drives the L-shaped plate 103 rotatably connected thereto to perform left-right reciprocating motions, and the L-shaped plate 103 drives the jet piston rod 106 fixedly connected thereto to perform left-right reciprocating motions, and the left-right reciprocating motions of the jet piston rod 106 control the jet piston cylinder 105 to perform piston jetting, thereby realizing the aeration mechanism 100 to aerate the sewage in the reactor 1, preventing the suspended matter in the sewage from sinking while ensuring that there is sufficient dissolved oxygen in the sewage, further oxidizing and decomposing the organic matter in the sewage, and keeping the sludge in a suspended state; The left hinge shaft 202 drives the driving plate 201 rotatably connected thereto to reciprocate left and right, the driving plate 201 drives the connecting frame 203 fixedly connected thereto to reciprocate left and right, the connecting frame 203 drives the pushing block 205 fixedly connected thereto to reciprocate left and right, when the pushing block 205 moves to the right, it pushes the suspended matter on the surface of the sewage into the suspended matter collecting box 11 on the right, thereby realizing the cleaning work of the floating matter in the sewage. Compared with the existing device, the present invention is conducive to the continuous removal of the floating matter in the sewage in a cycle, so as to facilitate the continuous removal of the floating matter; The output end of the second motor 13 drives the rotating shaft 302 fixedly connected thereto to rotate, and the rotating shaft 302 drives the rotating disk 301 fixedly connected thereto to rotate, and the rotating disk 301 drives the fixed shaft 311 on the surface to rotate, and the fixed shaft 311 drives the driving frame 312 on the surface to reciprocate left and right when rotating, and the driving frame 312 drives the driving rod 306 fixedly connected thereto to reciprocate left and right, and the driving rod 306 drives the connecting plate 303 fixedly connected thereto to reciprocate left and right, and the connecting plate 303 drives the filter plate 304 to move synchronously, and the filter plate 304 filters the sediment in the sewage, and the rotating shaft 302 drives the transmission cam 404 fixedly connected thereto to rotate while rotating; When the protruding end of the transmission cam 404 contacts the control button on the surface of the controller 405, the controller 405 turns on the telescopic switch of the telescopic disk 401, and the telescopic disk 401 controls the cleaning plate 403 to move through the vertical plate 402. At this time, the filter plate 304 has moved to the far right and starts to reset to the left, and the cleaning plate 403 moves to the right. While the cleaning plate 403 and the filter plate 304 move towards each other, the sediment filtered by the filter plate 304 is cleaned and pushed into the inside of the filtered material collection box 5; When the connecting plate 303 moves to the right, the fixed rack 305 is meshed with the transmission gear 502 for transmission, and the transmission gear 502 drives the rotating shaft 503 fixedly connected thereto to rotate, and the rotating shaft 503 drives the cleaning roller 504 fixedly connected thereto to rotate, and when the cleaning roller 504 rotates, the mesh of the filter plate 304 at the upper end is cleaned and unblocked to prevent the sediment from clogging the mesh and affecting the filtering effect; While the cleaning roller 504 is cleaning and unblocking the filter plate 304, the nozzle 506 is spraying the flocculant. Since the nozzle 506 is inclined, the flocculant will be concentrated on the connection between the cleaning roller 504 and the filter plate 304. When the flocculant is sprayed, the filter plate 304 and the cleaning roller 504 will be flushed, thereby further improving the cleaning efficiency of the cleaning roller 504 on the mesh of the filter plate 304. In addition, the cleaning roller 504 reciprocates left and right. When the cleaning roller 504 rotates, the flocculant is fully absorbed and evenly applied to the surface of the filter plate 304, so that the cleaned filter plate 304 moves to the left to the inside of the reactor 1. When the filter plate 304 with the flocculant moves into the reactor 1, the reaction of the sediment in the sewage is accelerated, thereby further improving the filtration of the sewage.
