The invention discloses a method for treating unsymmetrical dimethylhydrazine wastewater. The method comprises the following step: performing oxidation degradation treatment on unsymmetrical dimethylhydrazine wastewater by using persulfacte under catalysis of catalysis amounts of carbonate ions and/or bicarbonate radical ions, wherein the temperature of the unsymmetrical dimethylhydrazine wastewater is 40 DEG C or greater in oxidation degradation treatment. Compared with the prior art, the method disclosed by the invention has good removal and mineralization effects on unsymmetrical dimethylhydrazine, chemicals used in the method are easy to obtain and store, low in use cost, free of secondary pollution and environment-friendly, and in-situ treatment on high-temperature unsymmetrical dimethylhydrazine wastewater generated in engine run and rocket firing can be directly implemented. 本发明公开了一种处理偏二甲肼废水的方法，该方法包括：过二硫酸盐在催化量的碳酸根离子和/或碳酸氢根离子的催化下对偏二甲肼废水进行氧化降解处理，氧化降解处理时偏二甲肼废水的温度在40℃以上。与现有技术相比，本发明方法对偏二甲肼具有良好的去除和矿化效果，所用的药剂
