A flotation pipe 9 is provided on the left side of the inside of the flotation tank 1, and a water inlet pipe 10 is installed on the left wall of the flotation tank 1. The water inlet pipe 10 is used to discharge the sewage into the flotation tank 1 after flocculation reaction.

[0023] like Figure 2 As shown, a cleaning assembly 4 for cleaning the board surface is provided on the right side of the scraper plate 3, and the cleaning assembly 4 includes a mounting plate 401 and a hydraulic rod 402, and a hydraulic rod 402 is installed on the side of the mounting plate 401. The hydraulic rod 402 continuously retracts and retracts to drive the connecting frame 403 to move on the flotation tank 1, and the cleaning assembly 4 also includes a connecting frame 403 and a cleaning rope 404. The output end of the hydraulic rod 402 is installed with a connecting frame 403, and the connecting frame 403 moves while driving the cleaning rope 404 to move, and a cleaning rope 404 is installed on the inner side of the connecting frame 403. The cleaning rope 404 with a micro-elastic effect scrapes and cleans the surface of the scraper plate 3 when it promotes the scum to enter the side slag collection pool, thereby preventing the scum from adhering to the scraper plate 3 and bringing the scum back to the water surface, affecting the scum removal effect.

[0024] like Figure 3As shown, a mud discharge assembly 11 for reducing the water content of mud is arranged inside the sedimentation tank 8. The sedimentation tank 8 is used for sedimentation of sediment, and the mud discharge assembly 11 includes a mud discharge rod 1101, a mud discharge trough 1102, a connection box 1103 and a bottom plate 1104. The mud discharge rod 1101 is provided with a mud discharge trough 1102 on its surface. The mud discharge rod 1101 is driven by a motor to rotate at the bottom of the sedimentation tank 8. When rotating, the mud discharge trough 1102 is turned over. Since the sludge falls into the mud discharge trough 1102 by gravity, the mud discharge rod 1101 and the mud discharge trough 1102 are an integrated structure, and the mud discharge trough 1102 is about the mud discharge rod 110 There are two symmetrically arranged on the central axis. When the mud discharge rod 1101 rotates, the sludge can be flipped through the mud discharge trough 1102 and brought to the connecting box 1103.

When the sewage is precipitated, the conveyor belt 2 drives the scraper plate 3 to clean the scum on the water surface. When the scum is cleaned, the hydraulic rod 402 continuously retracts and drives the connecting frame 403 to move on the flotation tank 1. When the connecting frame 403 moves, it drives the cleaning rope 404 to move, so that the cleaning rope 404 with a micro-elastic effect is pushed by the scraper plate 3 to move the scum into the side slag collection tank. Its surface plays a role in scraping and cleaning, preventing sludge from adhering to the scraper plate 3 and bringing the sludge back to the water surface, affecting the sludge removal effect. The sludge sinks into the sludge tank 8 and the sludge discharge trough 1102 due to gravity. The sludge discharge rod 1101 is controlled to rotate at the bottom of the sludge tank 8 under the drive of the motor. When the sludge discharge rod 1101 rotates, the sludge can be flipped through the sludge discharge trough 1102 and brought to the connecting box 1103. The water content in the sludge is less during flipping. After flipping, the other sludge discharge trough 1102 can continue to collect sludge, thereby continuously working to complete the discharge of sludge.
