Description
Technical Field
[0001] The utility model relates to the technical field of coagulation and sedimentation, in particular to a high-efficiency physicochemical tower with automatic mud discharge. Background Art
[0002] Physical sedimentation of sewage relies on the difference in density between suspended solids and water to separate them. Commonly used sedimentation tanks include horizontal flow, radial flow, vertical flow, and inclined plate (tube) sedimentation tanks. Vertical flow sedimentation tanks are widely used in sewage treatment due to their advantages such as convenient sludge discharge, no need for scraping machinery, simple management, and small footprint. However, due to water distribution, the diameter of vertical flow sedimentation tanks is generally small. When treating large water volumes, multiple tanks are required to meet the sewage treatment requirements. At the same time, sludge discharge requires a lot of manual operation, and the sludge discharge time is difficult to control. Long sludge discharge time leads to large subsequent sludge treatment volumes and increased costs. Short sludge discharge time leads to anaerobic sludge turning and high suspended solids concentration in the effluent.
[0003] To overcome the above technical defects, it is now necessary to optimize and improve the original foundation to obtain an efficient physical and chemical tower with automatic mud discharge, which can solve the above problems. Utility Model Content

[0031] Furthermore, a mud discharge butterfly valve 45 is installed on the mud discharge main pipe 43. And it can be switched to a manual mud discharge butterfly valve 45 for mud discharge according to actual use.
[0032] Furthermore, an ultrasonic mud level meter 41 is installed in the tower body 1, and the ultrasonic mud level meter 41 is electrically connected to the main control system.
[0033] Furthermore, the water outlet section 3 includes a water outlet weir 31, a water collection channel 32, and a water outlet pipe 33.

[0037] Further, in another embodiment 2, as Figure 2-Figure 3 As shown, to flush the floating sludge to the bottom of the central tube, a sludge flushing device 5 is installed at the top of the tower body 1. The sludge flushing device 5 includes a tap water pipeline 51, an electric timing valve 52, and a spiral nozzle 53.

[0038] Water Intake Process: Sewage passes through the water inlet main 21 and is thoroughly mixed with the PAC agent in the PAC dosing line under the centrifugal rotation of the water inlet pump 23. The mixed sewage then flows through the pump outlet pipe 33 into the inner central barrel 15. The PAM agent in the PAM dosing line is added at the top of the central barrel. Simultaneously, sewage from the inner central barrel 15 overflows into the outer central barrel 14, where the sewage and agent undergo a coagulation reaction, forming large particles of alum. The mud-water mixture then enters the buffer zone 12. Under the action of gravity, the sludge enters the sludge zone 13, and the supernatant is precipitated in the sedimentation zone 11. To prevent the formation of floating sludge at the top of the central barrel, a floating sludge flushing device 5 is installed at the top of the central barrel. Under the control of the electric timing valve 52, clean water is periodically sprayed into the spiral nozzle 53 at the top of the central barrel, flushing the floating sludge to the bottom of the central barrel.
[0039] Discharge process: The supernatant in the sedimentation area 11 overflows through the discharge weir 31 and enters the water collection channel 32. The water collection channel 32 is set around the top of the tower body and collects all the supernatant to the outlet pipe 33.
[0040] Sludge Discharge Process: An ultrasonic mud level meter 41, installed at the top of the high-efficiency physicochemical tower, collects real-time information on the sludge level at the bottom and transmits this information to a computer program. The collected sludge level is compared with a set level. When the mud level exceeds the upper limit, a mud discharge solenoid valve 44 automatically opens to discharge the sludge. When the mud level falls below the lower limit, the solenoid valve 44 automatically closes to stop the discharge. Multiple mud collection and discharge branches 42 are installed at the bottom to collect the sludge at the bottom and collect it into the mud discharge main 43. Depending on actual usage, the manual mud discharge butterfly valve 45 can be switched to discharge the sludge.
