Abstract

The invention discloses a catalytic air flotation device for treatment of sewage, relating to a catalytic air flotation device. The device can solve the problem that soluble substances in water can not be removed when the existing air flotation device is used for treatment of the sewage. An air flotation tank of an air flotation machine is respectively provided with a water inlet pipe of the air flotation machine and a water outlet pipe of the air flotation machine, the bottom of the air flotation tank of the air flotation machine is communicated with one end of a gas dissolution and water inlet pipeline, the other end of the gas dissolution and water inlet pipeline is communicated with a water inlet at the upper part of a catalytic oxidation reaction container, a gas-liquid mixing pump is arranged on the gas dissolution and water inlet pipeline, a filler is arranged at the middle part of the catalytic oxidation reaction container, a water outlet at the bottom of the catalytic oxidation reaction container is communicated with one end of a gas dissolution and water outlet pipeline, the other end of the gas dissolution and water outlet pipeline is communicated with the water inlet at the bottom of the air flotation machine, and a release head of the air flotation machine is arranged on a port of the gas dissolution and water outlet pipeline. The catalytic air flotation device disclosed by the invention is used for treatment of the sewage.

Description

Technical field [0001] The invention relates to a catalytic air flotation device. Background technique [0002] The air flotation process uses highly dispersed tiny bubbles as a carrier to adhere to the hydrophobic-based objects in the water, so that the small bubbles and the object are regarded as a whole, and their overall density is less than water and floats to the water surface, thereby achieving solid-solid separation or The process of liquid-solid separation. This process can effectively remove colloids and suspended substances in water by adding flocculants (or without adding flocculants), but it cannot remove soluble substances in water, which greatly limits its efficacy and application range, especially When the content of soluble pollutants is high, its function and effect are greatly reduced. Summary of the invention [0003] The purpose of the present invention is to provide a catalytic air flotation device for treating sewage, so as to solve the problem that the cu...
