The invention relates to a comprehensive electroplating wastewater treatment method. The electroplating wastewater is divided into six brand-new classes, a chemical and biochemical combined process is adopted, a separate system drainage pipe network is adopted, the electroplating wastewater is divided into ink wastewater, complex wastewater, pretreatment wastewater, cyanogen-containing wastewater, chromium-containing wastewater and common electroplating wastewater, the six classes of wastewater respectively flows into respective underground adjusting tank through the pipe network, and is treated by respective process, and the effluent is discharged after reaching a standard. Because of the scientific water separating and stepwise pretreatment of a front-end chemical treatment part, different pollutants are respectively removed in different process sections according to characteristics, crossed enrichment and mutual reaction of the different pollutants are reduced to the greatest extent, and the pressure of microorganisms in the biochemical process is reduced. Treatment facilities for the six classes of wastewater are mutually connected and relatively dependent, and when inlet water quality fluctuates, a corresponding section is only required to be adjusted, the whole process is not influenced, the management is scientific and orderly, and operational risks are reduced.
