Description

Technical Field

[0001] The invention relates to the technical field, and in particular to a deep well aeration device without secondary pollution. Background Art

[0002] The activated sludge biological treatment process of wastewater uses a deep well as an aeration tank. The diameter of the tank is usually 1 to 6 meters and the depth is 150 to 300 meters. During treatment, the wastewater and the return sludge are mixed at the top of the well, flow downward along the inner wellbore, and after reaching the bottom of the well, they are diverted and flow upward from the outer wellbore to the degassing tank at the top of the deep well. Part of the mixed liquid overflows into the sedimentation tank for mud and water separation, and the precipitated activated sludge flows back to the deep well; part of the mixed liquid circulates inside the deep well.

[0003] In the current deep well aeration sewage treatment process, the return sludge is prone to adhere to the inner wall of the inner pipe when entering the deep well inner pipe, resulting in low return sludge treatment efficiency and incomplete treatment, which is easy to cause secondary pollution in the subsequent sludge treatment.

The sealing plate 3 is connected to the top of the inner tube 2 of the deep well, the electric telescopic rod 4 is connected to the sealing plate 3, the high-pressure nozzle 5 is connected to the bottom of the electric telescopic rod 4, one end of the conduit 6 is connected to the high-pressure nozzle 5, and the other end of the conduit 6 extends out of the sealing plate 3. The high-pressure nozzle 5 includes a nozzle body 7, a water inlet 8 and a water outlet 9. The nozzle body 7 is disc-shaped, the top of the nozzle body 7 is fixedly connected to the electric telescopic rod 4, the water inlet 8 is opened on the upper surface of the nozzle body 7, the water inlet 8 is fixedly connected to the conduit 6, and the water outlet 9 connects the cross section of the nozzle body 7 and the water inlet 8. The cross section of the water outlet 9 is a trapezoid that gradually approaches the water inlet 8. A pressure pump 10 is fixedly connected to the top of the conduit 6, and one end of the conduit 6 is connected to the pressure pump 10. The electric telescopic rod 4 drives the high-pressure nozzle 5 to move up and down to wash the inner wall of the inner tube 2 of the deep well. The pressure pump 10 draws water into the water inlet 8, and the water is sprayed outward from the water outlet 9 in a diffused shape to prevent incomplete flushing.
