【Technical articles】Electrochemical process treatment: electroplating wastewater and heavy metal wastewater
At present, the main traditional processes for treating electroplating wastewater and heavy metal wastewater generally include the following methods: chemical dosing sedimentation method, ion exchange method, membrane separation method, and biochemical treatment. However, these traditional treatment processes are difficult to meet the emission requirements after the standard is raised, especially the requirements for heavy metal and COD emission limits. Some processes can even achieve the standard discharge of heavy metal wastewater.
