The invention relates to a catalytic wet oxidation method of cyanogen-containing industrial wastewater. With the method, problems of catalysts in existing technologies, such as difficult shaping, low activity, easy crushing, short service life, low COD removing rate, and complicated technology, can be solved. According to the invention, industrial wastewater and gas containing elementary oxygen are adopted as raw materials. Under a reaction temperature of 230-300 DEG C, a reaction pressure of 3-10MPa, and a liquid space velocity of 0.5-2.5h<-1>, the raw materials contact a catalyst, such tat a COD removing rate is higher than 95%. After the treatment, a total cyanogen content is smaller than 5ppm. The adopted catalyst is a composite carrier loaded with at least one metal selected from Pt,Pd, Ru, Ir, or Rh, or an oxide of the metals. With the method provided by the invention, the problem is well solved. The method can be used in industrial treatment of cyanogen-containing industrial wastewater.
