Usage: biological wastewater treatment in buildings with the loading of redoxide material with a highly developed open porous structure for fouling with biofilm. The essence of the invention is a device for biological wastewater treatment "Redoxitank" includes a housing divided by vertical partitions into the primary settling chamber, anaerobic and aerobic reactors with biofilters and aerators, a system of pipes for supplying compressed air to aerobic reactors and pipelines for feeding wastewater and draining purified water. The device is equipped with a pressure relief chamber, air-lift pockets with a system of pipes for supplying compressed air and returning sludge water, a contact tank with a tubular mixer and a supply line for chlorine water, a tray for returning sludge water to the primary settling chamber and a secondary settling chamber with a receiving tray. The anaerobic chambers and the subsequent steps of the aerobic reactors are installed along the movement of the waste water with an increase in the longitudinal dimensions of the chambers of the first-stage aerobic reactor relative to the anaerobic reactor and the subsequent steps of the aerobic reactors relative to the previous ones in arithmetic progression. Biofilters of anaerobic and aerobic reactors are made in the form of containers installed on the frames in the reactors and filled with bulk loading blocks or installed in a vertical plane with gaps between them flat plates of redox material with a highly developed porous structure.
