Abstract

PURPOSE: To recover the valuable heavy metals from the waste water of the plating, by clocculating and separating organic substances, iron hydroxide, etc. contained in the waste water from the plating plant with an organic flocculant after the valuable heavy metals contained in the sludge obtained by flocculating and precipitating from the above waste water have been extracted as sulfates.
