The invention provides an electroplating wastewater treatment system and process, and relates to the technical field of wastewater treatment. The electroplating wastewater treatment system provided by the invention comprises a regulating tank, a pulse electric flocculation tank, an aerated iron-carbon inner electrolysis tank, an electric Fenton-like tank, a magnetic flocculation tank and a constructed wetland which are connected in sequence. Among them, the adjustment tank can remove large particles of impurities in the electroplating wastewater, and the wastewater can be preliminarily precipitated; the pulse electric flocculation tank can flocculate and precipitate heavy metals, cyanide and COD in the wastewater; the aerated iron-carbon internal electrolysis tank can remove the cyanide from the wastewater. Fenton-like ponds can further remove refractory organics, etc.; magnetic flocculation ponds can further flocculate and precipitate heavy metals, nitrates, etc. in wastewater; constructed wetlands can denitrify and dephosphorize wastewater, and the electroplating wastewater treatment method of the present invention Each processing unit in the system cooperates with each other to achieve the purpose of beautifying the environment. |
