FIELD: process engineering.
SUBSTANCE: invention relates to complex treatment of effluents. Effluent is fed into clarifying aeration tank 1 via line 3. Water falling into bioreactor 9 washes alternating inclined surfaces from cups 11 and cones 12. Air is fed by fluids countercurrent via porous ceramic tip of branch pipes 8. Then, water is fed into clarification chamber 6 whereto air is fed via tubes 7. Precipitation of clarifying tank 1 is removed at regular intervals via tube 16. Clarified water is drained via pipeline 4 into accumulation filter. Clean water is pumped from said accumulator.
EFFECT: higher quality and efficiency.
