Problems solved by technology

In the traditional aeration device, the method of reducing the aperture of the air outlet is generally used to generate smaller-diameter air bubbles. This kind of aerator has defects such as small air supply, easy blockage of the air outlet, and low efficiency.
[0003] The devices using the air flotation method have their own advantages, but they generally have the disadvantages of high energy consumption, complicated equipment, large floor space, and excessively large bubble diameters. Excessively large bubble diameters will cause many problems. Proportional to the square of the diameter of the bubble, the bubbles rise fast and the flocs are not easy to bond, and the flocs are not easy to rise to the water surface
In addition, all sewage purification devices cannot change the aeration method according to the change of water quality, and at the same time, the arrangement of aeration devices in water areas in cities will affect the urban landscape.

Abstract

The invention discloses a purifying device of effluent and making method and using method to aerate water, which is characterized by the following: the inlet pipe displays hollow cylinder shape; one end of inlet pipe connects the other end of composite sprayer glidingly, which transmits water to inlet pipe through pump pipe; the exterior of inlet pipe contains at least two transmitting pipes with equal distance, which transmits air to inlet pipe; the rotary table sprayer is set in the inlet pipe; the negative pressure guide pressurizing loop is set in the top of inlet pipe, which corresponds to sprayer; the sealed negative pressure composite gas-water bin is formed around sprayer; the rotary shaft is set on the exterior of inlet pipe, which connects rack.

Description

technical field [0001] The invention relates to a sewage purification treatment facility, in particular to an aeration and waterscape aeration device for sewage purification treatment, a manufacturing method and a using method. Background technique [0002] In sewage purification treatment, various aeration methods are mostly used to meet the amount of oxygen required in the metabolic process of aerobic microorganisms. Aeration devices are an important part of this sewage treatment method. In the traditional aeration device, the method of reducing the aperture of the air outlet is generally used to generate smaller-diameter air bubbles. This kind of aerator has defects such as small air supply, easy blockage of the air outlet, and low efficiency. [0003] The devices using the air flotation method have their own advantages, but they generally have the disadvantages of high energy consumption, complicated equipment, large floor space, and excessively large bubble diameters.
