The output shaft of the driving motor 17 is coaxially connected to the mounting rod 18. The bottom end of the mounting rod 18 passes through the bottom of the top cover 16 to drive the stirring rod 19 to rotate.

[0031] Specifically, a plurality of stirring rods 19 are fixedly connected to the circumferential outer wall of the mounting rod 18 by means of bolts. The stirring rods 19 are evenly arranged at equal intervals and are used to stir the wastewater in the treatment box 1 .

[0032] It should be added that scrapers 191 are symmetrically provided on the left and right sides of the mounting rod 18. The inner surface of the scraper 191 and one end of the stirring rod 19 corresponding to its position are fixedly connected by bolts, and the outer surface of the scraper 191 is in contact with the inner wall of the circumference of the processing box 1 to scrape off the sediment adhering to the inner wall of the processing box 1.

The adjusting motor 21 is fixedly connected to the bottom of the top cover 16 by bolts to drive the threaded rod 22 to rotate.

[0034] Specifically, the output shaft of the adjusting motor 21 is coaxially connected with a threaded rod 22 for driving the moving plate 24 to move. The top end of the threaded rod 22 passes through the top of the top cover 16 and is fixedly connected to a limiting plate 23 by bolts for limiting the highest position of the moving plate 24.
