Description

Technical Field

[0001] The invention relates to the technical field of deep well aeration, and in particular to a high-efficiency oxygenated deep well aeration sewage treatment device. 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] Deep well aeration can increase the concentration of dissolved oxygen in the mixed liquid. It is suitable for wastewater treatment with large load changes and high organic matter concentration. It has the advantages of stable operation and small footprint, but it is difficult to maintain. During the design, consideration should be given to preventing groundwater pollution caused by deep well leakage.

[0004] In the current deep well aeration process, there is a problem that the well is too deep, resulting in poor aeration effect, and the sewage near the ground has low oxygen content and poor fluidity, which affects the deep well aeration effect. Summary of the invention

The pressure pump 5 inflates the air intake pipe 4, and one end of the gas enters the aerator 6. The aerator 6 aerates the deep well inner tube 3 to increase the oxygen content of the pollutants in the deep well inner tube 3. Another part of the gas enters the aeration plate 8 from the air inlet pipe 4 to supplement oxygen near the top of the aeration tank body 1, thereby increasing the oxygen content and fluidity of the sewage.

[0025] An adjustment bracket 12 is fixedly connected inside the inner tube 3 of the deep well, and an adjustment ring 15 is fixedly connected inside the adjustment space.
