Ultrasound air floating type sewage treatment equipment

Abstract

The invention discloses ultrasound air floating type sewage treatment equipment which comprises an air flotation pond, a motor arranged at the lateral part of the air flotation pond, a support arm, anoscillating bar, an oscillating arm and an air flotation ball, wherein the motor is fixed at the lateral part of the air flotation pond, an output shaft of the motor is fixed at one end of the oscillating bar; the support arm is fixed at a position, corresponding to the oscillating bar, of the air flotation pond and is provided with a horizontal chute; one end, connected with the motor, of the oscillating bar is located in the chute of the support arm and slides to the left and right in the horizontal direction, and the other end of the oscillating bar drives the oscillating arm to oscillatein the vertical direction of the air flotation pond by a hinged shaft, so as to drive the air flotation ball fixedly connected to the oscillating arm to oscillate up and down; the air flotation ball is internally provided with an ultrasound generator; the ultrasound air floating type sewage treatment equipment also comprises a residue filtering device arranged at the top of the air flotation pond,and the residue filtering device comprises a plurality of hard filtering nets which can stretch automatically. The sewage treatment equipment is high in solid-liquid separation speed, can realize residue removal automatically, and is high in degree of automation.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to ultrasonic air flotation sewage treatment equipment. Background technique [0002] The air flotation machine is a kind of equipment for removing suspended solids, grease and various jelly in various industrial and municipal sewage. The equipment is widely used in the treatment of industrial waste water and municipal sewage such as oil refining, chemical industry, brewing, slaughtering, electroplating, printing and dyeing. [0003] The air flotation machine is a dissolved air system that produces a large number of fine bubbles in the water, so that the air attaches to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state of density lower than that of water. -Water treatment equipment for liquid separation. The air flotation machine is divided into super-efficient shallow air flotation machine, vortex concave air flotation m...

AI Technical Summary

Problems solved by technology

[0005] However, the solid-liquid separation effect of the existing air flotation machine is not very good, and the structure of the air flotation machine with good separation effect is relatively complicated, the operating cost is high, and it is difficult to use
