FIELD: chemistry.

SUBSTANCE: invention relates to comprehensive treatment of waste water for separate houses in small, medium and large settlements. The apparatus for treating waste water comprises a bioreactor 9 and an aeration tank-clarifier 1. The bioreactor 9, which is merged with an aeration chamber 5 and built into the inner cavity of the aeration tank-clarifier 1, is a hollow cylinder which is mounted on legs 10 which rest on the flat bottom of the aeration tank-clarifier 1. Inside the cylinder, alternating inclined surfaces are arranged in decks in form of cups 11 with a hollow bottom, rigidly attached to the wall of the cylinder, and cones 12 which are mounted to the wall by flexible tie members 13. An apparatus for feeding compressed air is placed under the bottom deck of cups 11 and is in form of a pipe 8 with a porous ceramic tip. A clarification chamber 6 is placed in the annular cavity of the aeration tank-clarifier 1 and has in its bottom part a self-contained air source 7. A treatment mechanism, which is in form of annular pipes 14, has an atomiser.

EFFECT: invention improves quality and efficiency of treating waste water.
