Abstract

The invention belongs to the technical field of aeration machines and discloses a high efficiency aerating apparatus for sewage treatment. The invention aims to solve the problems that the dissolved oxygen efficiency is low because the size of bubbles formed by stirring blades is large and the quantity of the bubbles is small and the sewage treatment effect is poor due to layering of the upper andlower parts of sewage in the using process of the conventional aeration machine. The high efficiency aerating apparatus disclosed by the invention comprises a floating rack, wherein a drive motor isarranged on the floating rack; the output shaft of the drive motor is connected with a stirring shaft; a stirring impeller is connected onto the stirring shaft; a jet nozzle is arranged at the periphery of the stirring impeller; a venturi tube is arranged at one end of the jet nozzle; the other end of the jet nozzle is connected with an ejection pipe; the ejection pipe is downwards obliquely connected onto the jet nozzle; and the outlet of the ejection pipe is positioned in lower sewage.

Description

technical field [0001] The invention belongs to the technical field of aerators, and in particular relates to a high-efficiency aeration device for sewage treatment. Background technique [0002] The aerator injects micro-bubbles directly into the untreated sewage through the air-diffusing impeller. Under the joint action of coagulant and flocculant, the suspended solids undergo physical and chemical flocculation, thereby forming large suspended solids flocculation. , Under the action of the buoyancy of the bubble group, the "floc" floats to the liquid surface to form scum, which is separated from the water by a scum scraper. [0003] There are also many technical documents about aerators in the prior art. For example, the invention patent of application number 201410831789.5 discloses an axial-flow inverted umbrella aerator, which includes a drive device, an output shaft, and an aeration impeller. The drive device passes the output The shaft is connected with the aeration ...
