Aeration device used for domestic sewage processing

Abstract

The invention discloses an aeration device used for domestic sewage processing. The aeration device used for domestic sewage processing comprises a tank body, a fixing support, a first motor, an aeration plate, a blower, a water inlet pipe, and a water outlet pipe; the top of the tank body is fixedly connected with the fixing support; a sliding plate is arranged in the fixing support; the upper surface of the sliding plate is fixedly connected with the first motor; a shaft stretching terminal of the first motor is fixedly connected with a stirring shaft; the stirring shaft is fixedly connectedwith stirring blades; the bottom of the tank body is fixedly connected with the aeration plate; the stirring blades and stirring rods are used for stirring sewage for sewage full mixing, the stirringblades are used for raising of upper layer sewage, so that full contact of sewage with the air and aeration on sewage are realized; the blower is used for conveying the air into the aeration plate for aeration of bottom layer sewage, at the same time, the air is introduced into a stirring shaft through a telescopic flexible pipe, and is introduced into sewage through gas outlets for aeration of middle layer sewage; and a spiral plate is adopted to drive bottom sewage to turn upward, so that mixing of sewage with the air is more full.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an aeration device for domestic sewage treatment. Background technique [0002] The random discharge of domestic 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. Air system and 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. Contents of the invention [0003] The ob...
