Existing sludge disposal routes include land utilization, landfill, building material utilization, incineration, etc. Land utilization is blocked due to excessive heavy metals; landfill is a temporary transitional technical route, which is combined with front-end deep dehydration and has become the route with the most application cases at this stage, but the amount of reagents added is large, the sludge increase is obvious, and there is secondary pollution; building material utilization has a high sludge moisture content and a small amount of admixture. A large amount of reagents are added to the front-end dehydration, resulting in strong sludge corrosion. At present, many collaborative cement projects have been shut down; incineration is currently the most thorough way to solve the sludge problem, and it is also the most mainstream technology for international sludge disposal. A Chinese patent discloses a sludge dehydration pretreatment device and method (authorization announcement number CN110228935B). The patented technology discloses a sludge dehydration pretreatment device and method. The device It includes mechanical crushing pretreatment equipment, a sludge delivery pump, a first mud-drug mixer, a first serpentine pipe, an ultrasonic reactor, a second mud-drug mixer, a second serpentine pipe, a stirring device and a thickening filter press; the mechanical crushing pretreatment equipment is used to crush large impurities in the sludge, and its outlet is connected to the sludge delivery pump; the first mud-drug mixer is respectively connected to the sludge delivery pump and the first serpentine pipe, and is used to mix the sludge conditioning agent with the sludge; the ultrasonic reactor is arranged on the outer wall of the pipeline between the first serpentine pipe and the second mud-drug mixer; the second mud-drug mixer is connected to the second serpentine pipe, and is used to mix the flocculant with the sludge; the inlet of the stirring device is connected to the second serpentine pipe, and the outlet is connected to the thickening filter press. The method has the advantages of short sludge conditioning time, thorough sludge modification, and high sludge dehydration efficiency. This patented technology solves the problems of low calorific value, high water content, and high sediment content of sludge in my country, large wear of traditional drying equipment, and complex operation and maintenance, resulting in high drying costs. Sludge disposal determines sludge treatment. All front-end sludge treatment unit technologies serve the back-end sludge disposal.

[0122] The servo motor 5 605 is started, and the servo motor 5 605 starts to drive the worm 2 604 to rotate. The worm 2 604 is meshed with the worm wheel 2 603. The rotating worm wheel 2 603 can drive the stirring rod 602 to rotate. As the stirring rod 602 rotates, the stirring frame 606 further mixes the sewage and flocculant in the water collection cylinder 217. The sewage is precipitated for 1 to 4 hours according to the reaction time between the sewage type and the flocculant.

[0123] When the sewage in the water collecting cylinder 217 is precipitated, the top of the sedimentation tank 207 of the sedimentation box 206 is aligned with the top hole plate 202;

[0124] The precipitate after flocculation of sludge in sewage can fall into the sedimentation tank 207;

[0125] When the sediment inside the sedimentation tank 207 is automatically discharged and cleaned, the servo motor 1 2106 is started to rotate counterclockwise, and the servo motor 1 2106 drives the worm 1 2105, so that the worm 1 2105 drives the worm wheel 1 2104 to rotate in one direction, so that the positioning rod 2103 rotates with the worm wheel 1 2104, drives the pulley 2 2107 thereon, and the pulley 2107 drives the transmission belt 2108, and the transmission belt 2108 drives the pulley 1 216 to rotate, and the transmission rod 215 is rotated through the pulley 1 216, and the spur gear 2 214 is driven through the one-way bearing 213 on the spur gear 1 212 ( The one-way bearing 213 is in a counterclockwise locked state and in a clockwise active state), and the spur gear 214 can mesh and rotate with the gear ring body 219, and the gear ring body 219 drives the sediment box 206 to rotate 45°, so that the position of the top of the sedimentation tank 207 in the sedimentation box 206 facing the top hole plate 202 gradually moves to be staggered with the hole position of the top hole plate 202, so that the top of the sedimentation tank 207 in the sedimentation box 206 is sealed through the top hole plate 202, and the bottom end of the sedimentation tank 207 is aligned with the hole position of the bottom hole plate 203, so that the sediment inside the sedimentation tank 207 can be discharged into the solid-liquid discharge pipe 301 through the discharge bucket 205;

[0126] For the sediment stuck on the inner wall of the sedimentation tank 207, the servo motor 1 2106 needs to be started clockwise. The started servo motor 1 2106 makes the positioning rod 2103 rotate in the other direction through the cooperation of the worm 1 2105 and the worm wheel 1 2104. The pulley 1 216 driven by the belt 2107 and the transmission belt 2108 rotates clockwise, and the spur gear 1 212 can be driven by the transmission rod 215 when the one-way bearing 213 is in the active state. The double toothed ring 211 is continuously meshed and rotated through the spur gear 1 212, so that the inner side of the double toothed ring 211 is meshed with the four outer toothed rings 210 at the same time, and the rotating outer toothed ring 210 drives the closed inner shaft 208 to rotate inside the sedimentation tank 207, and the inner spiral scraper 209 rotates along the inner wall of the sedimentation tank 207 along with the rotation of the closed inner shaft 208, and the sediment sticking to the inner wall of the sedimentation tank 207 can be scraped and cleaned by the inner spiral scraper 209;

[0127] The servo motor 1 2106 rotates counterclockwise again to reset the sediment box 206 after the sediment is cleaned, and the top is aligned with the hole of the top hole plate 202;

[0128] After the sewage is subjected to multi-stage sedimentation and water purification by the water purification sedimentation structure 2, the sewage will be directly discharged into the centrifugal inner filter cartridge 502 through the water inlet 505. After the servo motor 4 504 is started, the fixing frame 503 fixedly assembled with the centrifugal inner filter cartridge 502 can be driven by the servo motor 4 504 to rotate, so that the centrifugal inner filter cartridge 502 is driven by the servo motor 4 504 to rotate at a high speed, and the flocculated sludge remains in the centrifugal inner filter cartridge 502, while the separated water source falls between the centrifugal inner filter cartridge 502 and the centrifugal box 501, and then the water source after the sludge is removed is discharged through the drainage pipe 507 connected to the drainage channel 506, and the next step of sewage treatment is carried out;

[0129] The solid separated from the solid and liquid can be discharged into the solid-liquid discharge pipe 301 through the discharge hopper 508 by opening the second solenoid valve 509;

[0130] The solid-liquid discharge pipe 301 can separate the liquid remaining in the flocculated solids again, and start the servo motor 2 305. The servo motor 2 305 rotates the transmission screw 1 304. The rotating transmission screw 1 304 can move the flocculated solids along the inside of the solid-liquid discharge pipe 301 for discharge. When discharged, the flocculated solids will pass through the filter screen 302, and the filter screen 302 will drop the dripping residual wastewater into the wastewater tank 303. The wastewater inside the wastewater tank 303 can pass through the circulation pipe 307 connected to the circulation pump 306 to transmit the wastewater inside the wastewater tank 303 to the water inlet frame 9 again, and the wastewater is re-transmitted to the first water purification sedimentation structure 2 through the water inlet frame 9.
