METHOD OF BIOLOGICALLY TREATING WATER TO REMOVE HARD-TO-OXIDIZE ORGANICS

摘要

water treatment. SUBSTANCE: original water stream is transferred to dissipation stage with tangential speed 165-175 cm/s, dissipated at vertical water stream velocity 9-14 cm/s, and subjected to biosorption in spirally twisted state at vertical velocity 1.25-1.40 cm/s, in the course of which organics are oxidized by microorganisms immobilized on the surface of charge, whereas the latter is simultaneously biologically regenerated. Biologically purified water is finally filtered through dense charge bed. EFFECT: increased water purification degree. 1 tbl, 5 ex
