Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example

As shown in FIG. 1 , a low-energy-consumption aeration tank using air jet for stirring in this embodiment includes a tank body 1, and a cover plate 2 is provided on the top of the tank body 1. As shown in FIG. 6, the cover plate 2 is divided into A fixed cover 21 and a movable cover 22. The two fixed covers 21 are fixed on the tops of both sides of the pool body 1. The movable cover 22 is located in the middle of the two fixed covers 21 and is slidably connected with the two fixed covers 21. The movable cover The plate can be supported on two fixed cover plates. Since the sewage in the aeration tank has an unpleasant smell and is likely to cause air pollution, a cover plate is set on the aeration tank in this embodiment.
