The invention belongs to the field of environmental protection, and particularly relates to an ozone catalytic oxidation wastewater treatment device and a treatment method thereof, wherein the treatment device comprises a water inlet system, a catalytic oxidation tower, a spray tower and an ozone treatment system, hydrogen peroxide is used for oxidation pretreatment of wastewater, and the load ofa subsequent treatment unit is reduced; residual ozone after catalytic oxidation is used for carrying out spraying treatment on the pretreated wastewater, so that the ozone utilization rate is increased; an ozone catalyst packing layer with excellent performance is arranged in the catalytic oxidation tower to catalyze ozone to generate a large number of hydroxyl radicals with strong oxidizing property, so that the oxidation capacity of the system is greatly enhanced, and the improvement of the reaction effect is promoted. The method has the advantages of high ozone utilization rate, low operation cost and good treatment effect, and has a good application prospect.
Description
technical field [0001] The invention belongs to the field of environmental protection, in particular to an ozone catalytic oxidation wastewater treatment device and a treatment method thereof. Background technique [0002] As the national environmental standards and industry standards become more and more stringent, many original wastewater treatment facilities are difficult to meet the treatment requirements, especially some chemical industry wastewater has poor biodegradability, and it is difficult to meet the standards after secondary biochemical treatment. Therefore, advanced wastewater treatment technology is required. Research and development has become a hot issue that the whole society pays attention to. [0003] The existing wastewater advanced treatment technologies mainly include activated carbon adsorption, Fenton oxidation, electrocatalytic oxidation, and membrane separation technology, but all of them have application bottlenecks to varying degrees. The operat...
