[0035] The solid-liquid separation mechanism 3 includes an exhaust pipe 33, an air supply pipe 35, a transfer pipe 37, and a separation box 39. The exhaust pipe 33 is slidably provided on the contact oxidation bin 24. The air supply pipe 35 is respectively provided on the hydrolysis acidification bin 21, the contact oxidation bin 24, the sedimentation bin 29, and the disinfection bin 211. One end of the air supply pipe 35 is respectively connected to the hydrolysis acidification bin 21, the contact oxidation bin 24, the sedimentation bin 29, and the disinfection bin 211. The other end of the air supply pipe 35 is bolted to the exhaust pipe 33. The other end of the air pipe 35 is connected to the exhaust pipe 33. A transfer pipe 37 is rotatably provided on the contact oxidation bin 24. The transfer pipe 37 is a "T"-shaped structure. The transfer pipe 37 is located directly below the sliding track of the exhaust pipe 33. A separation box 39 is fixedly installed on the frame 1.

The sediment is sent to the transfer pipe 37 by the separation box 39 and discharged through the bottom end opening of the transfer pipe 37 to separate the solids in the sewage.

At the same time, the separation box 39 and the transfer pipe 37 are set up to separate and discharge the solid sediment generated in the sewage treatment process, thereby realizing solid-liquid-gas separation and improving the quality of sewage treatment. When maintaining and cleaning the sewage treatment equipment, the transfer pipe 37 is rotated, the exhaust pipe 33 is moved to the top of the transfer pipe 37 and bolted to the transfer pipe 37, and a cleaning liquid is introduced through the opening on the other side of the transfer pipe 37 so that the cleaning liquid can clean the solid and gas waste that may stick to the pipe wall, thereby improving the maintenance and cleaning efficiency of the sewage treatment equipment and indirectly improving the working efficiency of the sewage treatment equipment.

[0055] The overall working principle of sewage oil removal device:

[0056] First, the sewage is passed into the hydrolysis and acidification tank 21 for hydrolysis and acidification, and then the sewage in the hydrolysis and acidification tank 21 is passed into the contact oxidation tank 24 for oxidation, and then the sewage in the contact oxidation tank 24 is passed into the sedimentation tank 29 for sedimentation treatment, and then the sewage in the sedimentation tank 29 is passed into the disinfection tank 211 for disinfection treatment. Finally, the clean water produced after sewage treatment is discharged from the disinfection tank 211. At the same time, the exhaust gas produced in the hydrolysis and acidification tank 21, the contact oxidation tank 24, the sedimentation tank 29, and the disinfection tank 211 is sucked into the air supply pipe 35 by the fan, and then sent to the exhaust pipe 33 by the air supply pipe 35 for discharge. At the same time, the sediment produced in the sedimentation tank 29 passes through the bottom connection between the sedimentation tank 29 and the separation box 39, and uses the "U"-shaped pipe principle. The sediment enters the separation box 39 and is separated from the liquid through the separation box 39. The sediment is sent to the transfer pipe 37 by the separation box 39 and discharged through the bottom end opening of the transfer pipe 37 to separate the solids in the sewage. When the sewage treatment equipment is maintained and cleaned, the bolts between the exhaust pipe 33 and the air supply pipe 35 are released, and the transfer pipe 37 is rotated so that the openings are located on the upper and lower sides and the other side of the transfer pipe 37. The sliding exhaust pipe 33 is moved to the top of the transfer pipe 37 and is bolted to the transfer pipe 37. The cleaning liquid is introduced through the opening on the other side of the transfer pipe 37 so that the cleaning liquid is sprayed out of the remaining two openings of the transfer pipe 37 to clean the transfer pipe 37 and the exhaust pipe 33 at the same time.

[0057] Among them, sewage enters the hydrolysis and acidification tank 21 from the water inlet 22 for hydrolysis and acidification treatment, the coarse screen 23 preliminarily filters the large solid waste in the sewage, and the valve of the regulating control valve 27 moves in the separation chamber 28 to change the opening degree of the valve port of the control valve 27, so that the sewage in the hydrolysis and acidification tank 21 flows into the contact oxidation tank 24, and the gas is introduced through the air inlet pipe 25. The gas is sprayed into the sewage in the contact oxidation tank 24 through the nozzle 26 to carry out contact oxidation treatment on the sewage. After the sewage in the contact oxidation tank 24 is treated, it flows into the sedimentation tank 29 through the diversion wide pipe 210 for sedimentation treatment. The sewage after sedimentation treatment enters the disinfection tank 211 through the transmission pipe 212 for disinfection treatment, and the treated clean water is discharged from the water outlet 213;

[0058] When the sediment solids are separated, the motor 317 is started, and the motor 317 drives the driving roller 318 to rotate. The driving roller 318 drives the chain 316 to move on the guide rail 312, and the chain 316 drives the receiving frame 313 to move on the guide rail 312. The receiving frame 313 drives the filter rack 314 to move, so that the filter rack 314 filters the sediment at the bottom of the separation box 39. As the filter rack 314 moves, the filter rack 314 and the scraper 315 are pressed against each other, and the scraper 315 scrapes the sediment filtered on the filter rack 314. The sediment will enter the connecting pipe 310, and the filter rack 314 is forced to rotate to continue to move with the receiving frame 313, and is reset by the torsion spring after the filter rack 314 leaves the scraper 315.
