Abstract

PURPOSE: To completely treat a cyanogen compd. in waste by adding a copper compd. and an iron compd. to the waste.
CONSTITUTION: An iron compd. such as potassium ferricyanide and a copper compd. such as copper sulfate are added to waste contg. a cyanogen compd. such as waste water from a plating stage or a refining stage using a cyanide process and the waste is subjected to oxidative decomposition treatment with an oxidizing agent such as sodium hypochlorite. When matter having reducing power such as metallic iron powder is present in the waste, the waste is pretreated to magnetically separate magnetizable matter from nonmagnetizable matter. By the decomposition treatment, cyano-iron-complex in the waste is converted into separable salt and this salt is easily removed.
