METHOD OF TREATING HOUSEHOLD WASTE WATER CONTAINING ORGANIC CONTAMINANTS Russian patent published in 2013 - IPC C02F1/28 C02F1/02 C02F9/02 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical and agricultural industries and treatment of liquid household wastes which contain organic contaminants. The method of treating household wastes involves treating waste water with nanostructured boehmite with absorption of organic contaminants with particles of nanostructured boehmite until achieving a given degree of treatment of the waste water. The treated waste water is separated into treated waste water and a solid residue. The solid residue, which contains contaminated nanostructured boehmite, is collected and regenerated by supercritical water oxidation until complete oxidation of organic compounds absorbed by the nanostructured boehmite. The regenerated nanostructured boehmite is collected and reused for waste water treatment.

EFFECT: method enables repeated use of nanostructured boehmite to treat waste water and waste water treatment which satisfies environmental chemical pollution requirements.
