METHOD OF TREATING WASTE WATER FROM DISSOLVED ORGANIC POLLUTION Russian patent published in 2018 - IPC C02F1/28 C02F1/72 C02F11/08 C02F11/18 C02F101/30 

FIELD: water and air purification technology.

SUBSTANCE: invention can be used for cleaning domestic, technological, surface, agricultural wastewater from dissolved organic contaminants. Purification method comprises treating the wastewater with an adsorbent, separating the treated waste water into a treated waste water and a solid precipitate containing a contaminated adsorbent, collection of solid sediment and its treatment under supercritical water oxidation conditions at a temperature of 450–600 °C and a pressure of 22 MPa to complete oxidation of organic compounds. As an adsorbent, organic combustible wastes are used, the content of organic substances in the sediment is adjusted to the values of chemical oxygen consumption of 50–300 g O₂/l. Processing in conditions of supercritical water oxidation is carried out in the absence of oxidizing substances.

EFFECT: method provides simplification of the technological process, reduction of energy costs, increase of economic efficiency.
