Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, and more specifically to an aerated sludge treatment pool. Background Art

[0002] Sludge treatment is the process of reducing, stabilizing and rendering sludge harmless. The complex microorganisms in activated sludge and the organic nutrients in wastewater form a complex food chain. The activated sludge method is a method of sewage treatment that provides a certain sewage retention time in the pool to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge, and sewage is treated by aerobic microorganisms.

[0003] After searching, the utility model patent with announcement number CN208292734U discloses a sludge aeration device, including a treatment tank, a support frame, a rotating component, a flow-changing component, an oxygenation frame and an aeration disc; the rotating component used to drive the water flow to dissolve with oxygen is fixedly connected to the treatment tank, and the aeration disc used to mix air and water is connected to the output end of the rotating component by transmission; the oxygenation frame is fixedly connected to the top of the treatment tank; the patent achieves the goal of increasing the amount of oxygen to improve the efficiency of aerobic microbial treatment. However, the above patent still has the following shortcomings: the effect of introducing air into the treatment tank for aeration by relying solely on the flow-changing component is poor, and the position of the aeration disc is fixed, and the stirring position is fixed, which affects the stirring effect; and odor is generated during aeration treatment, which is directly discharged and affects the surrounding environment. For this reason, we propose an aerated sludge treatment tank. Utility Model Content
