The invention relates to a method for treating carbonization wastewater through industrial fine coke instead of activated carbon. The method comprises the following three steps: (A) carrying out the acidizing of the carbonization wastewater; (B) carrying out the absorption treatment of the wastewater in an absorption tower through the industrial fine coke; and (C) carrying out the regeneration and reclamation of the absorption saturated wet industrial fine coke through oxygen insulated high temperature heating or directly using the wet industrial fine coke to replace common fine coke and be doped into iron making sintering raw material without regeneration. Therein, during the step A, sulfuric acid or industrial waste sulfuric acid is used to regulate the pH value of the wastewater to 2.0 to 3.0; during the step B, fresh fine coke which is directly produced by a coke plant and has the grain size of 10 to 80 meshes is arranged in the industrial fine coke absorption tower or absorption trough; and during the step C, the absorption saturated wet industrial fine coke is regenerated and reclaimed through oxygen insulated high temperature heating at 300 to 450 DEG C or directly replaces common fine coke to be doped into iron making sintering raw material without regeneration. After the treatment, the removal rates of the chromaticity and COD value in the outputted water reach 65 percent and 85 percent respectively, thereby reaching the first level emission standard in Integrated Wastewater Discharge Standard (GB8978-96).
