The invention relates to a treatment method for acid pickling water and neutralized waste water in the tetrabromobisphenol A producing process. The existing problems of the enterprise are solved. After the waste water is treated, the resource comprehensive utilization of the waste water is realized, chlorobenzene is reclaimed, and the waste water meets the emission requirements of environment protection burea. The treatment method comprises the following steps: adding acid into the neutralized waste water, regulating the pH to 1-2, precipitating out tribromophenol, and then adding a polyacrylamide flocculant; filling the neutralized waste water treated by the flocculant into a centrifuge, separating by the centrifuge, mixing clear liquid and the acid pickling waste water, and separating out and reclaiming tribromophenol precipitates; entering a flash evaporation procedure after mixing the clear liquid separated in a centrifugal way with the acid pickling waste water, carrying out flash evaporation at a temperature of 60-80 DEG C under the pressure of subzero 0.09 MPa, realizing the azeotropy of the chlorobenzene and the water, evaporating the chlorobenzene with water steam, condensing, enabling the evaporated chlorobenzene to enter condensate, and reclaiming the chlorobenzene with the condensate; controlling the temperature of the waste water at 60-80 DEG C after flash evaporation, feeding in an MVR (Mechanical Vapor Recompression) system, reclaiming the condensate, and reutilizing crystallized solid salt.
