Abstract

The invention discloses a ceramic substrate catalyst and a preparation method thereof. A potassium permanganate aqueous solution, a manganese sulfate aqueous solution and a carrier are mixed and then are subjected to high temperature sintering; the carrier is prepared by mixing the following raw materials in parts by weight: 40-60 parts of kaolin, 20-40 parts of bentonite, 10-30 parts of spinel, and 10-30 parts of a puffing agent. With fly ash and kaolin as the carrier, the catalyst capable of high-efficiency catalysis of ozone oxidation is prepared and is used for improving the ozone utilization rate and the degradation rate of ozone on organic matters which are difficult to decompose; the ceramic substrate catalyst exists in a form of solid and is easy to separate, the loss of the catalyst is avoided, and thus the cost of wastewater treatment is reduced; the ceramic substrate catalyst has the characteristics of low cost, high catalytic performance and high stability, is used for catalysis of ozone oxidation for deep treatment of wastewater, allows the wastewater to meet reuse standards, reduces the cost of treatment, contains huge environmental and economic benefits, and has relatively profound social development significance and practical value.

Description

technical field [0001] The invention belongs to the technical field of ozone catalyst preparation, and in particular relates to a ceramic substrate catalyst and a preparation method thereof. Background technique [0002] Water is an indispensable material for the survival of all life in nature. It is also the most precious natural resource that cannot be replaced by industrial and agricultural production, economic development and environmental improvement, and is also an important resource that is indispensable for social development. my country's per capita water resources are only 2300m3, only 1 / 4 of the world's per capita water resources, ranking 121st in the world, and one of the 13 countries with the poorest per capita water resources in the world. [0003] Due to human production and living activities, a large amount of domestic sewage, industrial wastewater, agricultural return water and other wastes are directly discharged into water bodies without any treatment, cau...
