FIELD: wastewater processing.
SUBSTANCE: invention relates to a device for biological wastewater treatment, including a housing in which a carrier material for an attached biocenosis is located, and can be used to improve wastewater treatment efficiency with a temperature below 15 °C. The carrier material for the attached biocenosis is made with the possibility of heating from the inside and is connected to the energy supply unit by means of a connecting element.
EFFECT: invention allows maintaining optimal temperature regime for effective functioning of the biocenosis attached to the carrier material due to the ability to heat the biocenosis attached to the carrier material in cold water.
