Embodiment

[0008] Embodiment: a kind of air flotation machine (see accompanying drawing 1) of internal flow scattered air, it is made of a circular air flotation force head 14 and air flotation tank 15, baffle plate 7, water outlet weir plate 8, slag scraping mechanism 12, backflow The sewage treatment device and the clean water storage device formed by the pipe 13 are characterized in that the circular air floating power head placed on the side wall of the air floating tank is composed of a circular gas producing wheel that generates tiny bubbles, a return water inlet, and a rectifying plate. , a mixing chamber, a water inlet and a water outlet. The circular gas production wheel that produces tiny bubbles is placed in the lower part of the rectangular air flotation tank. There is a return water inlet below the gas production wheel. There is a mixing chamber above the rectifying plate, and water inlets and water outlets on both sides of the circular air-floating head, and the circular air...

Abstract

This invention relates to an air-floating machine of scattered internal current characterizing that a round air floating groove at the air floating groove is composed of a round gas-generating wheel, an inlet of back-flowing water, a commutating plate, a mixing chamber, a water inlet and an outlet, the working method includes: refluent water enters into the inlet to meet the gas-generating wheel,2, forming water with large volumes of tiny bubbles to go up and enter into the chamber, 3, a water inlet is set at the bottom of the side of the chamber and sewage flows through it to be combined with the bubbles, 4, the mixed water flows out from the outlet at the top of the chamber, 5, flowing smoothly and scratching dregs. Advantages: 1, combination probability is great since sewage and tiny bubbles are combined in a small mixing room, 2, current flows up quickly so that sewage will not roll in the chamber, 3, the commutation board stops wadding in the water from being crushed by the wheel.

Description

(1) Technical field: [0001] The invention relates to a sewage treatment device, in particular to an internal flow diffused air flotation machine. (two) background technology: [0002] The air flotation machine is a common equipment for sewage treatment. It relies on the generation of a large number of tiny air bubbles in the water to attach to the suspended solids to make the suspended solids float to the water surface to form scum, which is then scraped off with a scraper device. In recent years, diffuse air (bleed air) type air flotation machines have been widely used. When this kind of air flotation machine is working, the motor drives the water wheel to rotate, and the surrounding wastewater forms a vortex to create a vacuum, so that the outside air enters the intake pipe and the water wheel from the air inlet, under the action of hydraulic shearing and air bubble crushing mechanism , the gas is crushed into micro-bubbles and diffuses into the water, and uses them as a ...
