FIELD: technological processes.
SUBSTANCE: invention relates to wastewater heat treatment. Heat treatment plant for wastewater polluted with biological agents of pathogenicity group I–IV includes CIP-wash 13, cooling unit 11, common sewerage system 12, connecting pipelines, sensors, valves, automated process control unit, as well as two production lines, each of which includes accumulation tank 1, 6, metering pump-grinder 2, sterilizer 3, 8, pump sterilizer 4, steam generator 5. Plant is configured to be switched to manual process control. Capacities of process lines are interconnected with the ability to transport wastewater between the lines: storage tank 1 of the first process line is interconnected with sterilizer 8 of the second process line, storage tank 6 of the second production line is interconnected with sterilizer 3 of the first production line, storage tanks 1, 6 of both lines, and sterilizers 3, 8 of both lines are interconnected.
EFFECT: invention makes it possible to increase the reliability of equipment operation, ensure the possibility of transporting wastewater between containers and switching to manual control, as well as increase the service life of the plant.
