Ozonization water treatment method using manganese dioxide one-dimensional nano material as catalyst

The invention relates to an ozonization water treatment method using a manganese dioxide one-dimensional nano material as a catalyst. The invention provides a preparation method and a using method of the nano-catalyst, which belong to the technical field of water treatment and environmental catalysis. Manganese dioxide nano rods are obtained by a simple and convenient hydrothermal method and the manganese dioxide nano rods serving as the catalyst are added into a phenol wastewater-containing ozonization water treatment system to contribute to the degradation of phenol organic pollutants, so that a novel ozonization water treatment method is provided on the basis. The obtained manganese dioxide one-dimensional nano material has the characteristics of small dimension, high dispersibility, high separability and wide application prospect in ozonization water treatment.
