Abstract

The invention discloses an aerating device for treating domestic sewage. The aerating device comprises a tank, a fixing rack, a motor, aerating blades, an aerating plate, a water inlet pipe and a draining pipe and is characterized in that the fixing rack is fixedly connected to the top of the tank, a telescoping mechanism is fixedly connected to the lower surface of the fixing rack, a fixing plateis fixedly connected to the lower end of the telescoping mechanism, the motor is fixedly connected to the lower surface of the fixing plate, a left rotary shaft is fixedly connected to the shaft extending end of the motor, a right rotary shaft is arranged on the right of the left rotary shaft, the aerating blades are fixedly connected to the left rotary shaft and the right rotary shaft, and the aerating plate is arranged at the bottom of the tank. The aerating device has the advantages that an air blower is utilized to inject air into the aerating plate to aerate bottom sewage, the air is discharged through air nozzles, the aerating plate rotates under the counter-acting force of the air to achieve uniform aeration, the aerating blades are utilized to aerate surface sewage during aeration, and stirring rods are utilized to stir the sewage and break air bubbles to allow the sewage and the air bubbles are sufficiently mixed so as to increase an aerating effect.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an aeration device for domestic 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.
