Ozone air flotation advanced oxidation fluid treatment system

Abstract

The invention provides an ozone air flotation advanced oxidation fluid treatment system, which comprises a reaction tank, an ozone air flotation device, a plurality of groups of ultraviolet radiation devices and ballast devices thereof and an electric control system, wherein the front end and the rear end of the reaction tank are provided with an inflow area and an outflow area respectively, and the inflow area and the outflow area are communicated with the reaction tank; the ultraviolet radiation device groups and the ozone air flotation device are arranged in the inflow area, and the ultraviolet radiation device groups are arranged at the rear end of the ozone air flotation device; and the ozone gas passes through the air flotation device and then is atomized to form mist particles, themist particles are mixed with the fluid to be treated to form oversaturated high-pressure dissolved ozone aqueous solution, the oversaturated high-pressure dissolved ozone aqueous solution is contacted and reacted with the fluid to be treated in the inflow area under the irradiation of ultraviolet, then the solution flows into the reaction tank and is continuously fully contacted and reacted withthe fluid to be treated, and finally the reacted solution flows out through the outflow area.

Description

Technical field: [0001] The invention relates to an ozone gas flotation advanced oxidation fluid treatment system, which belongs to the field of fluid treatment. Background technique: [0002] Currently, ozone-based advanced oxidation technology (O 3 / UV,O 3 / H 2 o 2 etc.) are more and more widely used in the drinking water treatment process, but the continuous single gaseous ozone dosing device makes the ozone utilization efficiency in the reactor very low, and most of the ozone escapes from the reactor without reaction. Although the decomposition rate and utilization rate of ozone can be improved by filling the reactor with a solid catalyst and adding hydrogen peroxide, it makes the operation cost of advanced oxidation equipment high; and hydrogen peroxide is prone to occur during storage and transportation. Explosion, not safe. Therefore, a low-cost, safe and efficient system is needed to replace the above method. Invention content: [0003] The technical scheme o...
