FIELD: waste water treatment. SUBSTANCE: reduction-oxidation treatment of waste water with biomass comprises (i) charging regenerable redox mediator into system; (ii) oxidizing saturated reducing agents using indicated variety of regenerable redox mediator; (iii) reducing primary oxidation agents using indicated variety of regenerable redox mediator; and (iv) retaining indicated variety of regenerable redox mediator in treatment system in the form, which is insoluble in waste water and in which at least part of indicated biomass is repeatedly treated in stages (ii) and (iii) together with indicated variety of regenerable redox mediator. EFFECT: enhanced removal of hydrocarbons, food substances, toxic and stable organics, reduced formation of biomass, and improved oxygen transfer. 21 cl, 12 dwg
