Wastewater treatment catalyst and preparation method thereof

Abstract

The invention relates to a wastewater treatment catalyst and a preparation method thereof. The wastewater treatment catalyst comprises the following raw materials in percentage by mass: 15 percent of elemental iron, 4.5 percent of bivalent iron oxide, 17.5 percent of trivalent iron oxide, 30 percent of magnesium oxide, 2.7 percent of nickel, 1.4 percent of zinc and 28.9 percent of yellow mud. Theinvention has the advantages that the sintering stability of added metal materials and metal oxide materials is ensured by utilizing the inherent viscosity of the yellow mud, and the yellow mud does not contain impurities of metals and metal oxides per se, therefore, the purity of a sintering result is ensured; various metals and metal oxides have good uniformity and dispersibility in a process of repeated sintering; and the yellow mud volatilizes per se in the sintering process to form gaps, and therefore, catalyst particles have good hydrophilicity and dispersion rate.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a sewage treatment catalyst and a preparation method thereof. Background technique [0002] Water is the basic condition for human survival. However, with the development of the economy and the prosperity of the manufacturing industry, a large amount of various sewage is produced, which poses a huge threat to the living environment of human beings. And more chemical agents, resulting in high toxicity of the water body, which is a kind of wastewater that is difficult to treat. The currently commonly used catalysts have the disadvantages of unstable structure, loss with water, and short service life. Contents of the invention [0003] The purpose of the present invention is to provide a catalyst for sewage treatment and its preparation method, which overcomes the shortcomings of existing commonly used catalysts for sewage treatment such as unstable structure, loss with water and...
