What is electroplating wastewater?

2. Classification of electroplating wastewater based on pollutant composition and process linksIt can be mainly divided into three categories. 1). Chromium-containing wastewater: mainly hexavalent chromium (Cr⁶⁺), which is highly toxic and carcinogenic. It needs to be converted into low-toxic trivalent chromium (Cr³⁺) through chemical reduction (such as sodium sulfite), and
