Preparation method of wastewater oxidation treatment catalyst

The invention relates to the field of environmental protection, and in particular relates to a preparation method of a wastewater oxidation treatment catalyst. The preparation method comprises the following steps: adding anaerobic activated sludge, an inhibitor, ferrous chloride, nutrient substances and a metal element regulator into a biological anaerobic reactor, adding an activating reagent into sludge generated by anaerobic biological reaction of the materials, mixing, drying the mixed sludge, and carbonizing to obtain the sludge carbon-based catalytic material. The catalyst has the advantages of high catalytic activity, low loss tendency and long service life, and is suitable for industrial wastewater catalytic oxidation application. 本发明涉及到环保领域，具体涉及到一种废水氧化处理催化剂的制备方法，在生物厌氧反应器中加入厌氧活性污泥、抑制剂、氯化亚铁、营养物质、金属元素调节剂，物料经厌氧生物反应产生的污泥加入活化试剂混合，混合污泥再经干燥，碳化处理得到污泥碳基催化材料，该催化剂催化活性高，不易流失，使用寿命长，适合工业废水催化氧化应用。
