Semi-coke wastewater treatment method

The invention relates to the technical field of wastewater treatment, in particular to a semi-coke wastewater treatment method. The method comprises pretreatment, biochemical treatment and advanced treatment, and the pretreatment comprises the following steps: enabling semi-coke wastewater to sequentially pass through a pH adjusting unit, an evaporation and concentration unit and an ammonia blowing unit to obtain pretreated wastewater, wherein biochemical treatment wastewater is obtained after the biochemical treatment of the pretreated wastewater; the deep treatment is as follows: the biochemical treatment wastewater passes through a heterogeneous catalytic oxidation unit to obtain reuse water. The deacidification unit, the dephenolization unit, the oil removal unit and the like are removed, the evaporation and concentration unit is utilized, the operation temperature is controlled to be 40-60 DEG C, through pH adjustment, volatilization of phenolic substances is reduced, most organic matters are intercepted
