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

Abstract

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.

Description

technical field

[0001] The invention belongs to the field of water treatment and environmental catalysis, and relates to an ozonated water treatment method using manganese dioxide one-dimensional nanometer material as a catalyst. Background technique

[0002] In the current industrial production process, the discharge of organic waste water is increasing. Most of the organic matter is toxic and difficult to degrade. The pollution and threat to the ecological environment and human health are also becoming more and more serious. The chemical oxidation method is aimed at In the case of low concentration of organic pollutants in sewage and lack of recycling value, oxidizing agents are used to oxidize and degrade organic matter without causing new pollution to eliminate pollution. o 3 It has strong oxidizing property (En=2.07V), is easy to produce, and the conditions of the ozonation process are mild, easy to operate, and the oxidative degradation of organic matter is relatively...
