Description

Technical Field

[0001] This utility model discloses a sedimentation tank, belonging to the technical field of sewage treatment equipment, specifically relating to a super magnetic loading sedimentation tank. Background Technology

[0002] The main function of a sludge loading sedimentation tank is to remove suspended solids and organic matter from wastewater. Simultaneously, through sludge thickening and recirculation, it maintains the activity and quantity of microorganisms in the biological treatment section. The sludge loading sedimentation tank removes suspended solids and organic matter from wastewater through gravity sedimentation. These suspended solids and organic matter mainly include denser solid particles and suspended organic matter, thereby reducing the organic load on subsequent biological treatment structures. However, wastewater contains various types of suspended solids and organic matter, and traditional sludge loading sedimentation tanks cannot quickly remove and treat them, resulting in low treatment efficiency, low effluent quality, increased land area, and higher operating costs. Utility Model Content

[0004] Technical solution: A super magnetic loading sedimentation tank, a PAC stirring tank, a PAM stirring tank, a flocculation tank, a sludge scraping tank, a sludge buffer tank, and a sludge treatment tank;

[0005] The PAC mixing tank has an inlet pipe at its input end and an output end connected to the input end of the PAM mixing tank. The output end of the PAM mixing tank is connected to the input end of the flocculation tank. The sludge scraping tank is connected to the output end of the flocculation tank through a connecting pipe. The sludge buffer tank is connected to the sludge scraping tank.

[0006] The sludge treatment tank is equipped with a sludge return pump, a residual sludge pump and a sludge conveying pump. The sludge scraping tank is connected to the sludge return pump and the residual sludge pump. The sludge buffer tank is connected to the sludge conveying pump. The sludge return pump is connected to the PAM mixing tank.

[0007] In a further embodiment, a first flow hole is provided between the PAC mixing tank and the PAM mixing tank to connect the two, and a second flow hole is provided between the PAM mixing tank and the flocculation tank to connect the two.

[0008] In a further embodiment, the PAC mixing tank, the PAM mixing tank, and the flocculation tank are all equipped with a mixer and mixing blades.

[0009] In a further embodiment, the sludge scraper is provided in the sludge scraper tank and the upper part is provided with a triangular weir plate, and the connecting pipe is installed in the upper part of the flocculation tank and the sludge scraper tank.

[0010] In a further embodiment, a water outlet pipe is provided on the outside of the sludge scraping pool.

[0011] In a further embodiment, the bottom of the sludge scraping tank is connected to the input end of the sludge return pump via a first sludge pipe, and the output end of the sludge return pump is connected to the PAM mixing tank via a second sludge pipe.

[0012] In a further embodiment, a high-speed shear machine and a magnetic powder recovery machine are provided above the residual sludge pump. The input end of the magnetic powder recovery machine is connected to the first sludge pipe through a third sludge pipe, and the output end of the magnetic powder recovery machine is connected to the input of the high-speed shear machine.

[0016] Beneficial Effects: This novel super-magnetic loading sedimentation tank, by adding magnetic seeds and coagulants, utilizes the force of a magnetic field on charged particles to rapidly coagulate suspended particles and colloidal substances into larger particles, achieving water purification through sedimentation or filtration. This process significantly shortens coagulation and sedimentation time, achieving rapid settling and producing excellent effluent quality. Indicators such as total phosphorus (TP), suspended solids (SS), and turbidity are all superior to those of traditional processes. In particular, the removal efficiency of non-dissolved COD is more than 20% higher than that of conventional processes. Attached Figure Description

The mixture then flows into the PAM mixing tank 2 through the first overflow hole 12. Polymer material (PAM) is added to the PAM mixing tank 2, and the mixture is stirred evenly by the mixer 14 and the stirring blades 15. The mixture then flows into the flocculation tank 3 through the second overflow hole 13. Flocculant is added to the flocculation tank 3, and the mixture is stirred evenly by the mixer 14 and the stirring blades 15. The mixture then flows through the connecting pipe 8. The sludge enters the sludge scraper tank 4, where it is moved to the lower part by the sludge scraper 16. Water flows out through the outlet pipe 18 at the upper part. When the flow rate is too large, it flows through the triangular weir plate 17 into the sludge buffer tank 5. At the same time, the sludge enters the sludge return pump 9 through the first sludge pipe 19. The sludge return pump 9 flows into the PAM sludge tank 2 through the second sludge pipe 20. Simultaneously, the sludge is passed through the magnetic powder recovery machine 22 and the high shear machine 21 through the third sludge pipe 23 and enters the residual sludge pump 10 through the fourth sludge pipe 24. The sludge transfer pump 11 connects to the sludge in the sludge buffer tank 5 through the fifth sludge pipe 25 and flows out through the sludge outlet pipe 26.
