The water outlet 9 of the reaction tank is sloped, and the slope is towards the sedimentation separation tank, which avoids the accumulation and blockage of sewage at the water outlet 9 and ensures the smooth progress of the treatment process. The isolation grid 4 is located above the water outlet 9 to facilitate the isolation of the suspended matter separated after mixing with the medicine. The water pump 5 is connected to the sedimentation reaction tank through a water pumping pipe, and the water pumping pipe is located above the isolation grid 4. The high-pressure flushing gun 6 is movably installed on the top surface of the supporting body. The water pump 5 is externally connected to the clean water tank. The clean water precipitated in the sedimentation separation tank can be pumped out through the water pump 5 and the water pumping pipe. The high-pressure flushing gun 6 is externally connected to a high-pressure air compressor water pump. When the isolation grid 4 needs to be cleaned, the high-pressure flushing gun 6 is manually controlled to flush the isolation grid 4, which can effectively remove the accumulated dirt and sediment to prevent it from corroding or damaging the grid. The high-pressure water flow passes through the isolation grid 4 and also effectively flushes the cleaning device 8 below the sedimentation separation tank to prevent the sludge from solidifying.

[0031] The lifting support device 1 includes a cylinder 11, a lifting platform 12 arranged at the telescopic end of the cylinder 11, and a plurality of telescopic rods 13 arranged on the lower surface of the lifting platform 12. The plurality of telescopic rods 13 are symmetrically arranged on both sides of the cylinder 11. The cylinder 11 and the plurality of telescopic rods 13 are installed on the top surface of the supporting body. An electric slide 7 is provided on the lifting platform 12. The stirring device 2 is movably installed on the lifting platform 12 through the electric slide 7. The lifting support device 1 is correspondingly arranged. The lifting platform 12 is in the shape of a "mountain". The cylinder 11 is installed in the middle. The telescopic rods 13 are located at both ends, and the number is preferably two. The cylinder 11, as the main lifting power source, can ensure the smooth lifting of the lifting platform 12, and the telescopic rods 13 on both sides play a role of balance and auxiliary support, making the lifting process more stable and reliable. The stirring device 2 can rise and fall with the lifting of the lifting platform 12 to complete stirring at different depths. At the same time, it can move freely in the reaction tank driven by the electric slide 7, thereby realizing all-round and efficient stirring and drug application operations.

[0032] The stirring device 2 includes a support frame 21, a plurality of motors 22 and a plurality of stirring fans 23. The upper surface of the support frame 21 is equipped with a plurality of motors 22. The plurality of stirring fans 23 are connected to the plurality of motors 22 through connecting rods. The plurality of stirring fans 23 are located below the support frame 21. A medicine-applying device 3 is installed on the support frame 21. The support frame 21 spans the reaction tank. There are two motors 22 and preferably four stirring fans 23. Two stirring fans 23 are installed on each connecting rod, one above and one below, respectively located at different heights, so that the stirring is more comprehensive and uniform, and the sewage and the liquid medicine are fully contacted and reacted. The movement on the electric slide 7 avoids the appearance of dead corners and unmixed areas.

The medicine outlet hose is fixed to both sides of the bracket by a pipe clamp.

[0034] The cleaning device 8 includes a scraper fan 81, a spiral roller 82, a mud pump 83 and a control motor 84. The scraper fan 81 is installed at the bottom of the sedimentation and separation tank. The output end of the control motor 84 is connected to the spiral roller 82, and the spiral roller 82 is connected to the mud outlet pipe. The mud pump 83 is installed on the mud outlet pipe. The bottom of the sedimentation and separation tank is pyramidal, and all four sides are slopes. The sludge will naturally slide down to the central area under the action of gravity, so that the scraper fan 81 can collect the sludge more efficiently. The sewage from the outlet 9 is precipitated and the sludge slides down again, and is swept into the spiral roller 82 by the stirring fan 23. The spiral roller 82 rotates layer by layer to transport the sludge out, and cooperates with the mud pump 83 to complete the sludge cleaning. The spiral rotation of the spiral roller 82 effectively prevents the sludge from solidifying. The spiral roller 82 is located in a groove below the scraper fan 81, and the side walls of the groove are also sloped.

[0035] The communication methods between the devices all adopt the existing communication methods, which are not the innovation of this application.

[0036] Working principle: sewage is poured into the reaction tank from the water inlet, and the motor 22 of the stirring device 2 is further started to drive the stirring fan 23 to rotate. At the same time, the dosing metering pump 32 is started to apply medicine, and the medicine is injected through the medicine hoses 31 on both sides of the support frame 21. At this time, the support frame 21 is driven by the electric slide 7 to move, so that the medicine liquid is fully injected into the sewage, and the stirring fan 23 and the lifting support device 1 are lifted to complete all-round stirring and mixing;

[0037] The mixed sewage enters the sedimentation reaction tank for sedimentation. At this time, the suspended matter is blocked by the isolation grid 4. The pump 5 is started to pump out the clean water. At this time, the sludge is settled at the bottom and is cleaned by the scraper fan 81 at the bottom. It is swept into the groove where the spiral roller 82 is located. The spiral roller 82 is driven by the control motor 84 to rotate and transport, and finally cooperates with the sludge pump 83 to complete the sludge discharge;

[0038] When the isolation grid 4 needs to be cleaned, it only needs to be connected to the high-pressure flushing gun for flushing to complete the cleaning of the isolation grid 4. At this time, the high-pressure water flow passing through the isolation grid 4 can also effectively flush the residual sludge in the sedimentation separation tank, further increasing the sludge treatment effect.
