FIELD: water supply.
SUBSTANCE: invention is related to reactors and methods of anaerobic treatment of waste water. Reactor is arranged with internal circulation circuit with central flow channel. In annular space between central flow channel and reactor wall there are bearing elements installed for immobilisation of microorganisms. Between adjacent bearing elements there are flow tracks. Lower part of reactor under bearing elements is arranged in the form of space intended for reception of waste water with microorganisms floating in them. In process of reactor operation there are both floating microorganisms and microorganisms immobilised on bearing elements are provided. Treated waste water flows in the centre down and along bearing elements and again up, moreover, flow is arranged partially due to formation of gas by microorganisms. Reactor may also be used for treatment of waste water in food and mixed fodder industry, and also in paper and textile industry.
EFFECT: invention makes it possible to improve quality of waste water.
