The invention provides a treatment method for steel rolling waste oil. The method includes the following steps that: (1) a treatment liquid is added to waste oil, so that the treatment liquid can react with the waste oil until detection standards are satisfied, wherein the treatment liquid is a mixed acid; and (2) a reaction liquid in the step (1) is detected, if the pH value of the reaction liquid is less than 6.5, alkaline powder is added into the reaction liquid, so that the pH of the reaction liquid is adjusted to 7. With the method of the invention adopted, re-treatment devices such as adevice for additional distillation are not required; after the treating agent slowly reacts with the waste oil, and then the waste oil and impurities such as metal are converted into a water-soluble solution, and no waste smoke, waste residues, exhaust gas and odor are generated in a treatment process. 本发明提供了种轧钢废油的处理方法，包括如下步骤：(1)将处理液加入废油中进行反应，至达到检测标准；(2)检测步骤(1)的反应液，若PH值小于6.5，加入碱性粉末，将其PH值调整为7；所述步骤(1)中的处理液为混合酸。本发明的方法无需额外的蒸馏
