Device for waste water treatment.

摘要

An apparatus for the removal of a significant proportion of one or more metal contaminants from waste water comprises an electrolytic cell (10) having a plurality of anodes (16) and cathodes (17) preferably in an alternating arrangement. Each anode (16) has openings, such as perforations or open interconnected pores, to permit the waste water to flow through. Each cathode (17) is a reticulated structure, such as a metallized open-cell organic polymeric foam substrate which has been metallized first electrolessly and then electrolytically. In a particular form of the apparatus, the anodes (16) are also made of metallized open-cell organic polymeric foam substrates.
