Aeration tank with multiple aeration structures

Abstract

The invention discloses an aeration tank with multiple aeration structures. The aeration tank comprises a tank body, a support, a motor, an aeration plate, aeration heads, an air conveying pipe, a water inlet and a water outlet, wherein the top of the tank body is fixedly connected with a support; the center of the lower surface of the support is fixedly connected with a telescoping mechanism; the lower end of the telescoping mechanism is fixedly connected with the motor; the shaft extending end of the motor is fixedly connected with a rotating shaft; the rotating shaft is sleeved with a worm gear; two sides of the worm gear are respectively provided with a first worm and a second worm; two ends of the first worm and the second worm are fixedly connected with stirring plates; a third worm and a fourth worm are arranged below the first worm and the second worm; and the tail end of the rotating shaft is fixedly connected with the aeration plate. According to the invention, after sewage enters the tank body, the aeration plate is used for aeration of sewage at a bottom layer; the stirring plates are used for aeration of sewage at an upper layer; the aeration plate rotates during discharging of air, so air and sewage are more uniformly mixed, and aeration effect is improved; and sewage at a middle layer is stirred via the stirring plates so as to improve aeration effect.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an aeration tank with multiple aeration structures. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. A certain sewage residence time is provided in the pool to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge. The aeration tank is mainly composed of three parts: the tank body, the aeration system and the water inlet and outlet. The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular; aeration is a means to make air and water come into strong contact, and its purpose is to dissolve oxygen in the air in water. There are two main types of aeration methods, mechanical aeration and blast aeration. However, the existing aeration tanks often have a single aeration ...

The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular; aeration is a means to make air and water come into strong contact, and its purpose is to dissolve oxygen in the air in water. There are two main types of aeration methods, mechanical aeration and blast aeration. However, the existing aeration tanks often have a single aeration structure and low aeration efficiency, which is difficult to meet people's growing sewage treatment needs.
