At present, the wastewater treatment process of the domestic large and medium-sized paper mill mainly comprises primary physicochemical treatment, secondary biochemical treatment and tertiary Fenton chemical oxidation treatment. In the whole production process of the household paper industry, each working section and workshop are respectively provided with waste water and waste liquid, and meanwhile, as the household paper industry is densely filled with water, and the waste water quality conditions of different working sections are different, the fluctuation of the waste water quality, the water quantity and the pollution load is larger. Therefore, a proper wastewater treatment process is selected according to actual conditions, so that the wastewater treatment cost is further reduced, and the development cost is low, and the water treatment process technology with high efficiency is a development direction in the future.

Although Fenton oxidation is mostly adopted as three-stage treatment of the paper wastewater of the living paper factory at present, and certain effect is achieved. However, the Fenton treatment reaction consumes a large amount of medicaments, and a large amount of metal iron ions remain in the treatment liquid, so that iron mud is polluted. Therefore, in order to fundamentally get rid of the problems of iron mud pollution and disposal of Fenton water treatment, development of a more environment-friendly treatment process is needed. The ozone catalytic oxidation treatment is a comparatively environment-friendly water treatment process technology, because ozone can be rapidly degraded into oxygen in the air, the ozone residue problem can not exist, and the production cost can be effectively reduced. According to the water quality index of effluent after the MBR membrane at present, the subsequent ozone catalytic oxidation is adopted to further treat the biological refractory organic matters in the wastewater, so that the method is a rapid and efficient treatment process.

When the ozone post-discharge mechanism of the existing household paper wastewater treatment system is in actual use, ozone cannot be effectively contacted and catalyzed with a catalyst, the catalytic effect is poor, the catalyzed ozone cannot be effectively mixed and contacted with wastewater, the wastewater treatment effect is reduced, and therefore the ozone post-discharge mechanism of the household paper wastewater treatment system is provided for solving the existing problem.
