Embodiment Construction

[0041] The present invention is further described below in conjunction with specific embodiment:

[0042] like Figure 2-4 As shown, the dissolved air system provided by the present invention includes a sealed dissolved air tank, the upper end of the tank body 9 is the area with increased specific surface area, the lower end is the dissolved air water area 6, and an aerator 601 is arranged in the dissolved air water area. The dissolved air system of the present invention is particularly suitable for air flotation.

[0043] The dissolved air water area 6 is provided with an aerator 601, and an air inlet 901 is provided on the tank body, which is communicated with the air inlet end of the aerator, and the air outlet end of the aerator is located in the tank body. The air inlet 901 of the aerator communicates with the air outlet of the air compressor. The aerator preferably adopts the aeration tube, especially the microporous aeration tube. The microporous aeration tube prefer...

Abstract

The present invention is aimed at the technical problem of low dissolved air efficiency of the dissolved air device for air flotation in the prior art, and provides a dissolved air system, a dissolved air method and a sewage treatment system. The dissolved air system includes a sealed tank body, and a A water outlet is provided, and there are at least two dissolved air areas in the tank, including a dissolved air water area and a specific surface area increase area, and the specific surface area increase area is set above the dissolved air water area. The filtration system and the above-mentioned dissolved air system are provided with an air flotation releaser between the water outlet of the dissolved air system and the water inlet of the air flotation device. The dissolved air method means that water meets high-pressure gas after increasing the specific surface area to form dissolved air. The water is dissolved again through the aerator, and the dissolved gas system, the dissolved gas method and the sewage treatment system provided by the present invention can dissolve more gas and form relatively fine bubbles. The dissolution efficiency is high, the gas utilization rate is large, and the bubbles are small, so that the air flotation effect is good.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a dissolved gas system, a dissolved gas method and a sewage treatment system. Background technique [0002] Air flotation technology is to introduce a large number of highly dispersed micro-bubbles into the water to be treated. The micro-bubbles act as carriers to adhere to the particles or flocs suspended in the water to form a floating body with an overall density lower than that of water. The material floats to the water surface, forms scum and then removes it, and completes the separation of particles or flocs in the water from the water. Wherein, a dissolved gas device is used to release water containing a certain pressure gas, that is, dissolved gas water, into the liquid to be treated to generate microbubbles. At present, air flotation equipment is widely used in the sewage treatment industry, which is specially used to remove suspended solids and oil in sewage. ...
