FIELD: chemistry.SUBSTANCE: apparatus for purifying waste water comprises an aeration tank-clarifier 1 with pipes for inlet 3 of waste water and outlet 4 of clarified liquid and a bioreactor 9. The aeration tank-clarifier 1 is in the form of an open-top cylindrical vessel with a bottom 2, consisting of an aeration chamber 5 with a device for feeding compressed air and a clarification chamber 6. The bioreactor 9 is integrated with the aeration chamber and is a hollow cylinder mounted on legs 10, resting on the flat bottom 2 of the aeration tank-clarifier. Inside the bioreactor 9 there are layers of alternating tilted surfaces in the form of cups 11 with a hollow bottom and cones 12. The device for feeding compressed air is located under the lower layer of cups 11 and is in the form of a socket 8 with a porous ceramic ferrule. The clarification chamber 6 is located in the annular cavity of the aeration tank-clarifier and has in the lower part a self-contained air source. The purification mechanism, which is in form of annular tubes 15, is equipped with liquid sprayers.EFFECT: invention improves quality and efficiency of purifying waste water.5 dwg |
