Embodiment
[0052] This embodiment adopts a new type of aerator, and integrates centralized aeration and zoned oxygen supply technologies to provide an efficient oxygenation system in a limited space.
[0053] See figure 2 , a limited space efficient oxygenation system provided in this embodiment, comprising:
[0054] Aeration tank (2),
[0055] Several deflectors (5) are added along the direction of water flow in the aeration tank (2), and the aeration tank (2) is divided into several areas along the direction of water flow (such as figure 2 Shown as I, II, III three regions, in other embodiments also can be two regions or more regions), in each region, according to the specific situation of oxygen demand, different numbers of aerators are concentratedly arranged, Specifically, in this embodiment, the aerator is a rotary-cut mixed-flow aeration device (7). According to the specific situation of oxygen demand, different numbers of rotary cutting mixed-flow aeration devices are centra...
