FIELD: chemistry.
SUBSTANCE: invention relates to biological treatment of waste water. In a device 2 for pretreatment, foreign material is removed from waste water with organic products and the material is successively fed into a tank 3 for flux flattening and activated carbon accumulator 4. Gas is fed into the enclosure system 6 through an air blower 7. The treated water is separated into a solid precipitate and liquid in a separation membrane device 5. The filtrate 9 is fed into a sterilisation tank 10 using a pump 8. Treated water 11 and sludge are taken out of the installation through a pump 12.
EFFECT: invention enables efficient treatment of waste water.
