Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a device for reducing total phosphorus and suspended solids in effluent. Background Art

[0002] In sewage treatment, total phosphorus is adsorbed on activated sludge. After the sludge is precipitated in the sedimentation tank, the total phosphorus is discharged out of the system along with the sludge. However, during the sedimentation in the sedimentation tank, the sludge floats up and flows away with the effluent. Therefore, the total phosphorus and suspended solids in the effluent also increase. At present, flocculants are added to the sedimentation tank so that the flocculants can wrap the sludge, thereby increasing the sedimentation of the activated sludge and improving the floating of the sludge. However, the stirring structure in the sedimentation tank is not uniform enough for mixing the flocculant and sewage. At some positions in the sedimentation tank, the sludge is not wrapped by the flocculant, resulting in the discharged water still containing sludge, which makes the treatment effect of total phosphorus and suspended solids worse.

[0003] Therefore, a device is needed to reduce the total phosphorus and suspended solids in the effluent to solve the problem in the prior art that the flocculant and sewage are not mixed evenly, and the sludge is not wrapped by the flocculant in some positions in the sedimentation tank, resulting in the discharged water still containing sludge, which makes the treatment effect of total phosphorus and suspended solids worse.

[0030] Further Figure 3 As shown, the reciprocating assembly includes a mounting plate 500, a symmetrically distributed second limit sleeve 501 is fixed to the top of one side of the mounting plate 500, a transverse gear rod 502 is rotatably connected between the two second limit sleeves 501, a symmetrically distributed fixing rod 600 is fixed to the top of the outer wall of the transverse gear rod 502, a mounting shaft 504 is fixed to the middle of one side of the mounting plate 500, and a driving gear rod 503 is rotatably connected to the outer wall of the mounting shaft 504, and the driving gear rod 503 is rotatably connected to the transverse gear rod 502. The rod 502 is meshed, and a toothed disc 505 is rotatably connected to the bottom of one side of the mounting plate 500. A positioning shaft 506 is fixed to the edge of one side of the toothed disc 505. An opening 507 is provided on one side of the driving gear rod 503. The positioning shaft 506 is movably engaged in the opening 507. A third servo motor 508 is fixed to one side of the mounting plate 500. A first gear 509 is fixed to the output end of the third servo motor 508, and the first gear 509 is meshed with the toothed disc 505.

[0031] By setting up a reciprocating assembly, when the gear rod 503 is driven to rotate, the transverse gear rod 502 can be driven to reciprocate, and then the rack 601 can be reciprocated, so that the plurality of second gears 700 can rotate synchronously, and the toggle plate 101 can swing to drive mixing of the flocculant inside the sedimentation tank 100.

[0032] This solution has the following working process: when mixing the flocculants, by controlling the PLC controller 800, the two first servo motors 303 rotate synchronously, the first servo motor 303 rotates to drive the threaded rod 301 to rotate, the threaded rod 301 rotates to drive the moving block 300 to move downward, the moving block 300 moves to drive the fixed sleeve rod 202 to move downward until the stirring rod 201 is located inside the sedimentation tank 100, and then the flocculants are poured into the sedimentation tank 100, and the third servo motors 508 on both sides rotate by controlling the PLC controller 800, the third servo motor 508 rotates to drive the first gear 509 to rotate, the first gear 509 rotates to drive the toothed disc 505 to rotate, the toothed disc 505 rotates to drive the positioning shaft 506 to rotate, the positioning shaft 506 rotates and cooperates with the opening 507, so as to drive the gear rod 503 to swing, and drive the gear rod 503 to swing. 03 The swing drives the horizontal gear rod 502 to reciprocate left and right, thereby causing the rack 601 to reciprocate left and right.
