The invention provides a method for treating rectifying still residues by using a supercritical/subcritical water catalytic oxidation method, which comprises the following steps: by taking supercritical/subcritical water as a reaction medium, carrying out strong catalytic oxidation reaction on organic matters in the still residues and an oxidizing agent in the supercritical/subcritical water, and converting hydrocarbon components in the organic matters into carbon dioxide and water in a short time, the nitrogen component is converted into nitrogen or ammonia nitrogen, and the heteroatom component is converted into corresponding acid or inorganic salt. The method has the advantages of being fast in reaction, low in energy consumption, not prone to secondary pollution and the like, and is more economical and efficient compared with traditional methods such as incineration. 本发明提供一种利用超/亚临界水催化氧化法处理精馏釜残的方法，以超/亚临界水作为反应介质，使釜残中的有机物与氧化剂在超/亚临界水中发生强烈的催化氧化反应，在短时间内将有机物中的碳氢组分转化为二氧化碳和水，氮组分转化为氮气或氨氮，杂原子组分转化为相应的酸或无机盐。该方法具有反应快、能
