Domestic sewage aeration device

Abstract

The invention discloses a domestic sewage aeration device. The device comprises a pool body, a fixed frame, aeration blades, an aeration plate, an aeration head, a fan, a water inlet pipe and a drain pipe, wherein the fixed frame is fixedly connected with the top of the pool body; a first motor is fixedly connected with the left side wall of the fixed frame; a rotating shaft is fixedly connected with a shaft extending end of the first motor; a left screw rod and a right screw rod are arranged inside the pool body; a fixed plate is arranged below the rotating shaft; a second motor is fixedly connected with the lower surface of the fixed plate; a fixed bock is fixedly connected with a transmission shaft; the aeration blades are articulated with the left and right sides of the fixed block; a left sliding block is sleeved to the left screw rod; a right sliding block is sleeved to the right screw rod; air is conveyed to a vent hole in a fixed rod through the fan and is discharged into sewage; the sewage is subjected to aeration; the fixed rod rotates to stir the sewage; meanwhile air is conveyed to the aeration plate and is discharged into the sewage; the sewage in a bottom layer is subjected to aeration; during aeration, an aeration shaft moves longitudinally, so that the stirring range is expanded, and the aeration effect is enhanced.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an aeration device for domestic sewage. 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 tank to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between the sewage and the activated sludge. The aeration tank is mainly composed of the tank body It consists of three parts, the aeration system and the water inlet and outlet. The pool body is generally made of reinforced concrete, and the plane shape is rectangular, square and circular. The existing aeration methods are mainly divided into blast aeration and mechanical aeration. First, the existing aeration tanks often have a single aeration mechanism, long aeration time, low aeration efficiency, and the ability to treat sewage needs to be improved, making it difficult ...

[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 tank to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between the sewage and the activated sludge. The aeration tank is mainly composed of the tank body It consists of three parts, the aeration system and the water inlet and outlet. The pool body is generally made of reinforced concrete, and the plane shape is rectangular, square and circular. The existing aeration methods are mainly divided into blast aeration and mechanical aeration. The existing aeration tanks often have a relatively single aeration mechanism, long aeration time, low aeration efficiency, and the ability to treat sewage needs to be improved, making it difficult to meet people's growing sewage treatment needs.
