Aeration device for environmental protection and sewage treatment

Abstract

The utility model relates to the technical field of aeration devices for sewage treatment, and discloses an aeration device for environmental protection and sewage treatment, which comprises a mounting plate, a water turning mechanism is fixedly mounted on the top end surface of the mounting plate, and an oxygen conveying mechanism is fixedly mounted on the side surface of the water turning mechanism; the oxygen conveying mechanism comprises an oxygen storage tank, an upper through hole and a lower through hole are fixedly formed in the side face of the oxygen storage tank, and communicating vessels are fixedly installed on the inner walls of the through holes. When the water turning mechanism is turned on, the gas adding assembly is turned on to add sufficient oxygen into the oxygen storage tank, at the moment, along with operation of the water turning mechanism, the gas pump is turned on to pump out the oxygen in the oxygen storage tank through the first connecting pipe, the electromagnetic valve is further turned on, and the oxygen can be conveyed to the second connecting pipe through the gas pump and then sprayed out through the nozzle; and the oxygen is in contact fusion with sewage turned out by the water turning mechanism for aeration operation, so that the oxygen conveying amount of the device can be increased, oxygen required by aeration is provided, and the practicability and the aeration efficiency of the device are further improved.
