The invention relates to an intelligent control technology for electroplating synthetical wastewater, wherein through the steps of pH regulation of wastewater, oxidation, reduction, Cr<6+> filtering, heavy metal capture, settling of suspended solids, ion exchange and sludge treatment, the intelligent synthetical treatment of electroplating wastewater is realized, and the technology has the characteristics of high automation degree and good treatment effect. In the invention, the treatment process is finished by a sequencing bath method in a reactor, two or more reactors alternate to realize timely accurate dosing in the wastewater treatment process as well as real-time detection and control before discharge, the stability, reliability and economy of the wastewater treatment quality are guaranteed, and the wastewater treatment stably meets the requirements of the Discharge Standard for Electroplating Pollutants (GB21900-2008); furthermore, the intelligent unmanned operation can accurately control the wastewater treatment time, the drug adding amount and the wastewater treatment quality, so that the volume of the wastewater treatment equipment is reduced, and the treatment cost is lowered.
