High efficiency aeration tank for treating domestic sewage

Abstract

The invention discloses a high efficiency aeration tank for treating domestic sewage. The high efficiency aeration tank comprises a tank body, a fixed rack, a motor, an air blower, a water inlet pipeand a drain pipe, wherein the top of the tank body is fixedly connected with the fixed rack; the motor is fixedly connected with the outer wall of the right side of the fixed rack; a shaft extension end of the motor is fixedly connected with a driving shaft, a right half bevel gear and a right half bevel gear sleeve the middle part of the driving shaft, and a worm is arranged under the driving shaft; rotating shafts are respectively arranged at the right side and the left side of the worm; each rotating shaft is fixedly connected with a plurality of aeration plates; a gear sleeves the lower end of the worm; two aeration sliding blocks are respectively arranged at the left side and the right side of the gear. Aeration blades are used for stirring surface layer sewage so as to raise the sewage, thus enlarging the contact area between the sewage and the air; the surface layer sewage is subjected to aeration, so that the aeration effect is improved; therefore, stirring plates are used forstirring the sewage, so that the aeration effect is improved. The aeration plates are used for stirring the sewage while exhausting to the sewage, so that the bottom sewage is upturned, and air bubbles are more evenly mixed into the sewage.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a high-efficiency aeration tank for treating 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 pool to meet the oxygen required by aerobic microorganisms and the mixing conditions for 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 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 into water. However, the existing Aeration tanks often have a single aeration structure and low aeration efficiency, making it difficult to meet people'...
