Problems solved by technology

[0002] At present, the traditional air flotation machine of wastewater treatment equipment in the water treatment industry needs to add inorganic flocculants and organic flocculants to achieve the effect of air flotation, and its scope of application is small, the removal rate of COD is low, the operation is complicated, and the cost of wastewater treatment is high.
[0003] The traditional air flotation device is cumbersome to operate, and it is necessary to select the type of flocculant for the wastewater. At the same time, it needs to be equipped with a flocculant dissolving system, a control system, and manual guarding. The addition of flocculant will inevitably increase the cost of water treatment and increase Excessive manpower and material resources

Embodiment Construction

[0026] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, the modified air flotation device includes: gas source 2, oxygen generator 3, ozone generator 4, air flotation equipment 5, catalytic oxidation device 6, first sewage pump 7, second sewage pump 8, first flow meter 9. The second flow meter 10 , the first aeration pan 11 and the second aeration pan 12 .

[0028] The gas source 2, the oxygen generator 3 and the ozone generator 4 are connected in sequence.

[0029] The first sewage pump 7, the first flow meter 9, the air flotation device 5, the second sewage pump 8, and the second flow meter 10 are connected in sequence.

[0030] The oxygen generator 3 supplies air for the ozone generator 4 and the sewage entering the air flotation device. In order to supply air to the sewage entering the air flotation device, the oxygen generator 3 divides a branch and co...

Abstract

A modifying and air floating apparatus used for sewage treatment is characterized in that the apparatus comprises: a gas source; an oxygen producer connected with the gas source; an ozone system connected with the oxygen producer; a first sewage pump used for lifting wastewater to be treated to an air floating device; the air floating device connected with the first sewage pump and used for aerating entering wastewater; and a catalytic oxidation system arranged behind the air floating device and used for receiving the wastewater from the air floating device, wherein the ozone system provides ozone for the air floating device and the catalytic oxidation system to carry out aeration. The modifying and air floating apparatus used for sewage treatment does not need a flocculating agent, directly omits the flocculating agent adding link used in traditional air floating apparatuses, uses ozone to aeration, and allows the aerated wastewater to directly enter the catalytic oxidation device in order to realize outward discharging after standard reaching.

Description

technical field [0001] The invention relates to a modified air flotation device for sewage treatment, which belongs to the field of sewage treatment. Background technique [0002] At present, the traditional air flotation machine of wastewater treatment equipment in the water treatment industry needs to add inorganic flocculants and organic flocculants to achieve the effect of air flotation, and its scope of application is small, the removal rate of COD is low, the operation is complicated, and the cost of wastewater treatment is high. . [0003] The traditional air flotation device is cumbersome to operate, and it is necessary to select the type of flocculant for the wastewater. At the same time, it needs to be equipped with a flocculant dissolving system, a control system, and manual guarding. The addition of flocculant will inevitably increase the cost of water treatment and increase Excessive manpower and material resources. Contents of the invention [0004] The obj...
