FIELD: waste water treatment. SUBSTANCE: installation includes combined construction containing biofilter with sprinkling system, air tank-settler with water-jet aeration, mixing chamber, circulation pump, process pipelines (I), and also nitrificator (II) with structure analogous to that of I and supplemented by helium-neon lasers mounted on the sprinkling system trays. Reactor III serving to prepare organic substrate is provided with helium-neon lasers and mechanical aerator. Denitrificator IV is filled with charge of synthetic cloth. Initial waste pipeline is connected to mixing chambers I and II and to reactor III; pipeline withdrawing treated water from I is connected to mixing chamber II; discharge pipeline of circulation pump to sprinkling system of apparatus I, mixing chamber II, and reactor III; the latter, in turn, is connected through pipeline with mixer mounted on lateral pipeline from II to IV. The charge in IV is composed of separate polyamide-fiber frieze strands joined to each other by longitudinal and cross braiding and is stretched on sawtooth framework. EFFECT: enhanced waste treatment efficiency. 3 cl, 3 dwgm |
