ABSTRACT:
A hybrid chemical/biological process which is highly effective to destroy the herbicide, Atrazine, in wastewater solutions is herein disclosed. The process comprises subjecting the atrazine molecule in an aqueous carrier to ozone to produce the oxidized product, diamino-s-triazine and thereafter, metabolizing the diamine in soil having indigenous and selected microorganism capable of degrading the diamine to carbon dioxide. Also disclosed is a disposal system capable of preforming the process of the invention in a single system.
