Abstract

The invention discloses an advanced oxidation device for wastewater, and belongs to the technical field of advanced oxidation. The problem of low ozone utilization efficiency is solved. According to the technical key points, the advanced oxidation device for the wastewater comprises an ozone generation device and a reaction tank; a gas conveying pipe is arranged between the ozone generation deviceand the reaction tank, the two ends of the gas conveying pipe communicate with the ozone generation device and the reaction tank correspondingly, the reaction tank is provided with a circulating pipewhich communicates with the reaction tank and the gas conveying pipe, the reaction tank is provided with an overflowing pipe, and a water discharging valve is mounted on the overflowing pipe; and theoverflowing pipe is higher than the junction of the gas conveying pipe and the reaction tank and lower than the junction of the circulating pipe and the reaction tank, and the reaction tank is provided with an air blowing device. Ozone participates in reactions for multiple times, the utilization efficiency of ozone gas can be effectively improved, the effect of reducing ozone gas consumption isachieved, the energy consumption of the ozone generation device is reduced, and the effect of energy conservation is achieved.

Description

technical field [0001] The invention relates to the technical field of advanced oxidation, in particular to a waste water advanced oxidation device. Background technique [0002] Advanced oxidation technology (Advanced Oxidation Process, referred to as AOPs), also known as deep oxidation technology, is characterized by the generation of hydroxyl radicals with strong oxidizing ability. Macromolecular refractory organic substances are oxidized into low-toxic or non-toxic small molecular substances. According to the way of generating free radicals and the different reaction conditions, it can be divided into photochemical oxidation, catalytic wet oxidation, sonochemical oxidation, ozone oxidation, electrochemical oxidation, Fenton oxidation, etc. Ozone oxidation is mainly achieved through direct reaction and indirect reaction. The direct reaction refers to the direct reaction between ozone and organic matter. [0003] In the direct reaction of the traditional ozone oxidation...
