WATER PURIFICATION PLANT Russian patent published in 2018 - IPC C02F9/02 C02F1/78 B01D24/48 C01B32/30 

FIELD: water and air purification technology.

SUBSTANCE: invention relates to the field of water purification and water treatment, and can be used for purification of drinking, technical and waste water for drinking and household, industrial and agricultural water supply on filtering plants, jointly using the ozone treatment and sorption processes. Water purification plant comprises contact-filtering vessel 1 with the activated carbon 2 granular charge and drainage-distribution system 4, ozone-water mixture ejector 6, level sensors unit 7, ozone destructor 8, water for purification supply pipeline 13, water for rinsing supply pipeline 16, purified water discharge pipeline 23, bypass pipeline 20, pump 21 and shut-off devices 15, 17, 19, 22, 24, rinse water discharge pipeline 26, ozone generator 9 with ozone supply pipeline 10 and electrically connected to the level sensors unit 7, ozone generator 9, pump 21 and shut-off devices 15, 17, 19, 22, 24 control unit 27. Contact-filtering vessel 1 under the activated carbon 2 granular charge is provided with supporting gravel layer 3 and rinsing ejector 5. Drainage distribution system 4 is located in the gravel layer 3. In the upper part the contact-filtering vessel 1 is provided with the residual ozone 11 return line connected to the ozone supply pipeline 10, and connected to the rinsing ejector 5 air discharge line 12. Rinsing water supply pipeline 16 is provided with the discharge pipeline 18 with shut-off device 19. Discharge pipeline 18 is connected to the rinsing ejector 5.

EFFECT: invention allows to increase the ozone use degree and the filtering charge regeneration degree while reducing the rinsing water flow rate.
