The precipitated sludge is transported by the sludge pump 13 to the first magnetic separation mechanism 2 for magnetic separation treatment.

[0023] One side of the scraper plate groove 21 is slidably connected to the outer side of the strong magnetic roller 18, and the scraper plate groove 21 is inclined, and the output end of the scraper plate groove 21 is inclined downward and passes through the magnetic powder separation box 14 and is located on the outer side of the magnetic powder separation box 14. The strong magnetic roller 18 adsorbs the magnetic powder in the sludge on the surface, and then scrapes off the magnetic powder adsorbed on the strong magnetic roller 18 through the scraper plate groove 21, and discharges the magnetic powder through the inclined design. The top of the side of the guide plate 22 close to the strong magnetic roller 18 is slidably connected to the outer side of the strong magnetic roller 18, and the end of the guide plate 22 close to the strong magnetic roller 18 is inclined inward, diverting the sludge to the middle of the strong magnetic roller 18, increasing the contact between the sludge and the outer surface of the strong magnetic roller 18, and preventing the sludge from flowing to the two ends of the strong magnetic roller 18.

The outer side of the magnetic powder separation box 14 in the second magnetic separation mechanism 3 is located at the output end of the scraper plate groove 21 and is fixedly installed with a second guide tube 7.

[0025] Working principle: During use, the sewage is coagulated through the first reaction tank 9, the second reaction tank 10 and the third reaction tank 11, and then precipitated through the sedimentation tank 12. The precipitated sludge is pumped by the sludge pump 13 to the first magnetic separation mechanism 2 for the first magnetic separation. The sludge enters the interior of the separation tank 19 through the injection pipe 15 and is guided by the guide plate 22 through the bottom end of the strong magnetic roller 18 and discharged from the discharge port 16. The driving end of the servo motor 17 drives the strong magnetic roller 18 to rotate. The rotating strong magnetic roller 18 adsorbs the magnetic powder in the sludge on the surface of the strong magnetic roller 18. When the adhered magnetic powder rotates to the top of the scraper plate groove 21, the magnetic powder is scraped off by the scraper plate groove 21 and falls into the interior of the scraper plate groove 21, and is discharged through the downward inclined output end of the scraper plate groove 21. The discharged magnetic powder falls through the first guide pipe 6 to the interior of the second reaction tank 10 to continue the coagulation reaction. The sludge after magnetic separation is discharged to the second magnetic separation mechanism 3 through the discharge port 16.

[0026] The second magnetic separation mechanism 3 performs secondary magnetic separation treatment on the sludge. The sludge is transported to the interior of the separation tank 19 through the injection pipe 15. The magnetic powder in the sludge is separated again by the strong magnetic roller 18, and the separated magnetic powder is discharged into the magnetic powder collection tank 5 through the second guide pipe 7 through the scraper plate groove 21. The separated sludge is discharged into the sludge tank 4 through the discharge port 16, thereby realizing the recycling of the magnetic powder.
