WASTE WATER TREATMENT PLANT Russian patent published in 2017 - IPC C02F9/06 C02F1/24 C02F1/463 C02F1/465 B03D1/14 C02F1/28 

FIELD: chemistry.

SUBSTANCE: plant includes flotation cell 1 with insoluble electrodes 2, a floating filtering charge 3, floating sorption active charge, soluble electrode 4. Flotation cell 1 contains partitions made in the form of four cylinders 5 with an upper part in the form of conical collecting device 6 installed coaxially with respect to each other. The upper part of the side wall of the first and the third and the lower part of the second and the fourth upstream cylinders 5 are perforated. The upper parts of cone devices 6 are provided with vertical tubes 7 with ends arranged at the same level. Floating filtering charge 3 is located between the fourth cylinder 5 and the wall of housing 8 of flotation cell 1. The floating sorption-active charge is located below floating filtering charge 3. In the space between the second and the third cylinders 5, annular bubbler 13 is formed. Soluble electrode 4, which is a mixture of iron and copper balls packed into a dielectric perforated box, is located in the first cylinder 5 at a distance from the bottom. Ultrasonic generator 11 is mounted below soluble electrode 4.

EFFECT: invention allows to increase the efficiency of wastewater treatment.
