Disclosed is a method for processing a poor organic phase after solvent extraction indium extracting. The method includes: A, poor organic phase regeneration, namely, mixing the poor organic phase after solvent extraction indium extracting with regenerant, standing for layering, and separating to obtain a regenerated organic phase, wherein the regenerant is a mixture of oxalic acid and hydrofluoric acid; B, dechlorinating, namely, mixing the regenerated organic phase with water, standing for layering, and separating to obtain a dechlorinated organic phase; and C, acid pickling, namely, mixing the dechlorinated organic phase with pickling agent sulfuric acid solution for acid pickling, standing for layering, and separating to obtain a purified organic phase. By the method, the poor organic phase is continuously purified and regenerated, so that impurities such as iron, arsenic, tin, silicon dioxide, antimony, chlorine entrained in the organic phase are eliminated, and the service life of the organic phase is prolonged. In addition, by the method, the rate of removal of chlorine in the poor organic phase is higher than 85wt%, and a condition for subsequent recovery of zinc in indium extracting residual liquid is provided.
