High-efficiency aeration device for sewage treatment

Abstract

The invention discloses a high-efficiency aeration device for sewage treatment. The device comprises a pool body, a support frame, a water inlet pipe, an aeration plate, a blower and a drainage pipe;the top of the pool body is fixedly connected with the support frame, a shaft extending end of a first motor is fixedly connected with a driving shaft, and the left and right ends of the driving shaftare provided with a left rotating shaft and a right rotating shaft respectively; the bottom of the pool body is slidably connected with the aeration plate, and an aeration shaft is arranged above theaeration plate; the outer wall of the right side of the pool body is fixedly connected with a second motor, a shaft extending end of the second motor penetrates through the side wall of the pool bodyand is fixedly connected with the aeration shaft, aeration rods are utilized to stir sewage at the bottom layer to make the sewage fully mixed with bubbles, and the aeration efficiency is improved; abristle brush is utilized to brush aeration heads on the upper surface of the aeration plate, the aeration heads are prevented from being blocked by sludge, and in the aeration process, the aerationplate moves left and right to expand an aeration range and make aeration more uniform; aeration blades are utilized to raise sewage at the surface layer to make the sewage at the surface layer fully in contact with air, and the sewage at the surface layer is aerated.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a high-efficiency aeration device for sewage treatment. Background technique [0002] The random discharge of sewage will have a great negative impact on the environment. At present, people often use aeration tanks to treat sewage. The aeration tank is a structure that uses activated sludge method for sewage treatment. The system and the water inlet and outlet are composed of three parts. 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. The aeration structure of the aeration device is single, and the mixing of sewage and air is not sufficient, resulting in low aeration efficiency, and it is difficult to meet people's growing sewage treatment needs.
