METHOD OF PURIFYING WASTE WATER FROM OIL PRODUCTS AND SUSPENDED SUBSTANCES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC C02F9/04 C02F1/28 C02F1/78 C02F1/52 C02F1/40 B01J20/16 B01J20/26 

FIELD: water and air purification technology.

SUBSTANCE: group of inventions can be used for cleaning of waste water contaminated with oil products and suspended substances. Method for purifying waste water from oil products and suspended substances comprises feeding the sorbent into cleaning tank 1, hydromechanical mixing of water with sorbent for 2–10 minutes with simultaneous circulation of hydraulic mixture and supply of ion-ozone mixture into it through ejector 7 of ozone generator 8. Mixing process is stopped for 2–15 minutes for sedimentation of sorbed substances, which are directed to reservoir-accumulator of sludge 14. Purified water is pumped out. Sorbent used is a sorbent obtained by sputtering modified alkyd resin on the surface of aluminosilicate hollow microspheres. Device comprises cleaning tank 1 made in the form of a cylinder with a cone-shaped bottom, in the upper part of which there is a loading branch pipe 2, mixing device 3, initial water supply pipeline 4 and hydraulic mix circulation pipeline 6 through ejector 7 of ozone generator 8 into sprayer 9 located in lower part of tank 1. Cone-shaped bottom is connected via sludge discharge pipeline 13 with reservoir-accumulator of sludge 14.

EFFECT: group of inventions increases efficiency of treating waste water contaminated with oil products and suspended substances, simplifies the cleaning process using a simple small-size plant and using a floating sorbent.
