Abstract
PURPOSE: To decompose and remove organic contaminants contained in chemical copper plating waste water at a high removal rate by adding palladiym chloride to the waste water kept at high pH, heating the waste water to form precipitation, removing the precipitation, subjecting the waste water to oxidizing treatment at low pH, and containing the waste water with activated carbon.
CONSTITUTION: Chemical copper plating waste water containing such contaminants as EDTA, formaldehyde, and copper is added with an alkali agent to adjust the pH to above 12, added with palladium chloride, and heated to 30W80°C. After removal of resulting precipitate, the waste water is added with a mineral acid to adjust the pH to within 1W3. added with an oxidizer for oxidizing treatment, again added with a mineral acid to adjust the pH to within 2W4, added with activated carbon, and subjected to solid-liquid separation treatment to provide treated water.
