Method for removing organic dye stuffs and heavy metals from wastewater.

摘要

A process for removing color impurities such as dye stuffs from wastewater solutions and simultaneously removing heavy metal contaminants is described. The process includes passing the wastewater solution through an electrolytic cell, having an anode of iron, an iron alloy, or an insoluble iron compound to generate ferrous iron at the anode which then reacts with hydroxide ion generated at the cathode causing a coprecipitation of the impurities with insoluble ferrous hydroxide.
