The oblique flow channel 6 connects the clean water area 5 with the water distribution area 3. The transmission mechanism is located below the spoiler 2, and includes a transmission motor 14, a main gear 17, a main gear 20, a slave gear 19, a slave gear 22, a driving shaft 15, a driven shaft 23, a transmission chain 18, and a transmission chain 21. The main gear 17 is connected to the main gear 20 through the driving shaft 15, the driving shaft 15 passes through the sedimentation tank 16 and is connected to the transmission motor 14, and both ends of the driving shaft 15 are connected to the inner wall of the sedimentation tank 16 through bearings. The main gear 17 and the main gear 20 are connected to the slave gear 19 and the slave gear 22 through the transmission chain 18 and the transmission chain 21, respectively. The slave gear 19 is connected to the slave gear 22 through the driven shaft 23, and both ends of the driven shaft 23 are connected to the inner wall of the sedimentation tank 16 through bearings. A sealing gasket is provided at the connection between the active pump 15 and the sedimentation tank 16. The tops of the transmission chain 18 and the transmission chain 2 21 are connected via a support rod 13 , and the bottom of the support rod 13 is connected to the device frame 11 .

[0013] When the sedimentation tank for water pollution prevention and control is used, sewage is put into the water distribution tank 1, and the sewage first passes through the perforated wall 4, which has many perforations. When the sewage passes through these perforations, some large garbage will be initially filtered out, and these large garbage can be fished out through the top opening of the water distribution tank 1. The sewage passes through the perforated wall 4 and enters the water distribution area 3. The sewage is precipitated in the water distribution area 3. As the sedimentation time increases, the water and sludge in the sewage begin to stratify, and the sludge settles downward to the sludge bucket 10, and the clean water is located at the upper part. As the sewage continues to enter, the water distribution area The capacity becomes larger, and the clean water surges upward and passes through the baffle plate 2. The baffle plate 2 will reduce the force of the clean water surging upward to prevent the impact force from being too large and driving the sludge. The clean water enters the oblique flow pipe 6 through the baffle plate. Several oblique flow pipes 6 in the oblique flow sedimentation area are all designed in an inclined shape. One is to reduce the force of the clean water surging upward, and the other is to further precipitate and separate the clean water. A small amount of sludge in the clean water will be blocked by the inclined side wall of the oblique flow pipe 6, slide down the slope and settle, and the clean water flows into the clean water area 5 through the oblique flow sedimentation area, and finally flows into the outlet trough 8 through the outlet 7 for discharge.

[0014] The separated sludge settles on the sludge bucket 10 at the bottom, and the sludge on the sludge bucket 10 is finally discharged through the sludge discharge pipe 9. When a large amount of sludge settles on the sludge bucket 10 and has a high overlap with the clean water in the water distribution area and cannot be effectively separated, the transmission motor 14 of the transmission mechanism is started, and the transmission motor 14 drives the driving shaft 15 connected thereto to transmit, and the main gear 17 and the main gear 20 provided on the active pump 15 rotate accordingly. Since the main gear 17 and the main gear 20 are connected to the slave gear 19 and the slave gear 22 through the transmission chain 18 and the transmission chain 21 respectively, the slave gear 19 and the slave gear 22 rotate together, thereby forming a transmission mechanism, so that the transmission chain 18 and the transmission chain 21 are connected to the slave gear 19 and the slave gear 22. The support rod 13 between the chains 21 moves, and through the forward and reverse rotation of the transmission motor 14, the support rod 13 performs a reciprocating motion of moving back and forth, and the support rod 13 drives the device frame 11 fixedly connected at its bottom end to move back and forth, and the sludge scraper brush 12 fixedly connected at the bottom end of the device frame 11 reciprocates back and forth, and the sludge scraper brush 12 contacts the surface of the sludge bucket 10. In the process of the sludge scraper brush 12 moving back and forth, the sludge scraper brush 12 will brush off the sludge deposited on the sludge bucket 10, which plays a role in cleaning the sludge bucket 10. The sludge bucket 10 is cleaned in time to avoid excessive sludge deposited on the sludge bucket 10 and a high degree of overlap with the clean water on the top of the water distribution area 3, which affects the separation effect. The cleaned sludge is discharged through the sludge discharge pipe 9.

[0015] In summary, the sedimentation tank used for water pollution prevention and control has a simple structure and is easy to use. Through the transmission mechanism, the sludge scraper brush moves back and forth on the sludge bucket, and the sediment on the sludge bucket is scraped off, thereby ensuring the sedimentation and separation of the sludge bucket; the oblique flow channel is adopted to ensure the sedimentation and separation effect; the perforated wall is adopted to play a role in preliminary separation and filtration. The sedimentation tank effectively separates the sludge and water in the sewage and is suitable for large-scale promotion and application.
