Aeration tank used for domestic sewage processing

Abstract

The invention discloses an aeration tank used for domestic sewage processing. The tank comprises a tank body, a stand, a motor, a gas pipe and an air blower; the stand is fixedly connected to the top of the tank body, the motor is fixedly connected to the lower surface of the stand, and a transmission shaft is fixedly connected to the shaft-extension end of the motor; a left movable board and a right movable board are arranged in the tank body, a connecting rod is arranged between the left movable board and the right movable board, cams are arranged on the transmission shaft in a sleeving mode, a plurality of aeration rods are fixedly connected to the lower end of the transmission shaft, an aeration board and an aeration pipe are fixedly connected to the bottom of the tank body, the air blower is fixedly connected to the left side wall of the stand, the air blower transports air to the aeration board and the aeration rods, and sewage of the bottom layer is subjected to aeration by the air blower; the cams drive the left movable board and the right movable board to swing left and right to stir the sewage, so that the aeration effect is improved; worms drive stirring boards to rotate to stir the sewage; the aeration rods stir the sewage of the bottom layer while discharging the air, and the aeration effect is further improved.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an aeration tank for domestic sewage treatment. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. It is an important and commonly used sewage treatment equipment and plays a huge role in the field of sewage treatment. The pool provides a certain sewage residence time to meet the oxygen required by aerobic microorganisms and The mixed conditions of 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 tank body is generally made of reinforced concrete, and the plane shape is rectangular, square and circular. Existing aeration methods are mainly divided into blast aeration and mechanical aeration. Existing aeration tanks often have low aeration efficiency and cannot meet people's increasing deman...

[0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. It is an important and commonly used sewage treatment equipment and plays a huge role in the field of sewage treatment. The pool provides a certain sewage residence time to meet the oxygen required by aerobic microorganisms and The mixed conditions of 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 tank 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 low aeration efficiency, which is difficult to meet people's growing sewage treatment needs.
