The invention belongs to the technical field of wastewater treatment, and specifically discloses a treatment method for benzene-containing wastewater. The method includes the following steps of 1, electrolytic catalysis, 2, UV oxidation, 3, anaerobic acidification, 4, anoxic denitrification and 5, aerobic nitrification. The treatment method has the thorough degradation effect, no elements difficult to treat are introduced in the treatment process, the wastewater can be thoroughly degraded into small molecular substances such as H2O, CO2 and N2, the biodegradability of the benzene-containing wastewater treated by the method can be significantly improved, and pollutant factors such as nitrobenzene, aniline, ammonia nitrogen and COD in the wastewater can be greatly reduced. Compared with theprior art, the cost is low, operation is convenient, pollutant factors can be completely eliminated, and the method has strong industrial application prospects.
