Abstract

The invention relates to electroplating wastewater treatment process and equipment. The process mainly comprises the following steps that: an organic matter and a heavy metal ion in water are physically adsorbed by a composite material; after being physically adsorbed, the organic matter is degraded by microorganisms to destroy the adsorbing balance so that the physical adsorption is continuously carried out; and after being physically adsorbed, the heavy metal ion enters the interior of the composite material in an internal diffusion way and carries out ion exchange with the composite material to destroy the adsorbing balance so that the physical adsorption is continuously carried out. The invention prolongs the service life of an adsorbing material and avoids the trouble for frequently replacing the adsorbing material.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an electroplating wastewater treatment process and equipment. Background technique [0002] Electroplating is the use of chemical and electrochemical methods to plate various metals on the surface of metals or other materials. Electroplating technology is widely used in machine manufacturing, light industry, electronics and other industries. The composition of electroplating wastewater is very complex, except for cyanide (CN - ) wastewater and acid-base wastewater, heavy metal wastewater is a type of wastewater that is potentially extremely harmful in the electroplating industry. According to the classification of heavy metal elements contained in heavy metal wastewater, it can generally be divided into chromium (Cr)-containing wastewater, nickel (Ni)-containing wastewater, cadmium (Cd)-containing wastewater, copper (Cu)-containing wastewater, zinc (Zn)-containing waste...
