Active aluminum oxide supported catalyst for high-salinity water treatment

The invention belongs to the technical field of high-salinity water treatment, and particularly relates to an active aluminum oxide supported catalyst for high-salinity water treatment, wherein an active metal is loaded on an active aluminum oxide carrier. According to the invention, the active alumina type catalyst loading the active metal is prepared by using the impregnation-calcination method;and the analysis results find that the catalytic activity of the catalyst loading the single-component active metal is low, the catalytic activity of the Mn-Ni/gamma-Al2O3 is the best, the removal rates of COD and TOC can respectively reach 43.26% and 63.26% in 60 min, and after the catalyst is repeatedly used 6 times, the TOC removal rate still reaches 62.45% and the catalytic activity is not obviously reduced while the dissolution amounts of Mn and Ni are always less than 0.5 mg/L, so that the catalyst has good stability and good reusability in high-salinity water treatment. 本发明属于高盐水处理技术领域，更具体地，本发明涉及一种用于高盐水处理的活性氧化铝
