High-efficiency aeration device for sewage treatment

Abstract

The invention discloses a high-efficiency aeration device for sewage treatment. The high-efficiency aeration device comprises an outer shell, a first winding roller, a serpentine pipe, rotary motors, a blower and damping mechanisms, wherein the upper end of the shell is provided with the first winding roller; a rotating shaft of the first winding roller is provided with a positive-and-negative-rotation motor B; the left and right ends of the shell are symmetrically provided with bar-shaped teeth which are engaged with gears; the serpentine pipe is arranged between and fixedly connected with the left gear and the right gear; the left and right ends of the serpentine pipe are separately provided with a sleeve; the left side of the shell is fixedly connected with a positive-and-negative-rotation motor A; the left side of the blower is fixedly connected with an air outlet pipe; the air outlet pipe is fixedly connected with a plurality of nozzles and provided with a tee pipe; the lower end of the shell is symmetrically provided with the damping mechanisms; and each damping mechanism comprises an inverted U-shaped plate, a spring B and a supporting plate. The high-efficiency aeration device provided by the invention is simple in structure and convenient to operate, improves aeration efficiency through different ways so as to improve sewage treatment effect and has long service life.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a high-efficiency aeration device for sewage treatment. Background technique [0002] The aeration tank is a device for biochemical treatment of sewage. After the sewage enters the aeration tank, it reacts organically with the active mud in the tank, and the harmful substances are decomposed into harmless substances, which are discharged after the water is clarified. Oxygen, the so-called aeration, is to continuously inject air into the water, or use mechanical stirring to dissolve the oxygen in the air into the water; the current aeration methods mainly include blast aeration and mechanical aeration. Air is to use the aerator to inject air into the aerator head and diffuse it into the water to form bubbles, and dissolve oxygen in the water at the air-liquid interface. Ordinary aeration devices have a single means, so that the aeration tank is not fully aerated, resulting in incomp...
