The invention relates to an H acid production industrial waste water treatment method. The method comprises the steps of extraction, re-extraction, evaporation, chromotropic acid synthesis and the like. After the waste water is homogenized and averaged, naphthalenesulfonic acid substances in the waste water are extracted by using a specially-selected extraction agent, an extraction phase is re-extracted by using alkaline liquid, the extraction phase is recycled after being regenerated, and the re-extraction liquid is used for synthesizing chromotropic acid. The raffinate is adjusted to be neutral and then enters an evaporation system so as to recycle sodium sulfate, and the desalted evaporated and condensed water is treated by an aeration biofilter or active carbon and is then discharged up to standard. The process design is reasonable, the operability is high, and the problems for comprehensive treatment and resource utilization of H acid production industrial waste water are effectively solved.
