BIOLOGICAL PLANT FOR TREATING AND UTILIZATION OF EFFLUENT Russian patent published in 1997 - IPC

FIELD: equipment for bioprocessing of effluent. SUBSTANCE: plant can be used for desactivation of nuclear power units of water-surface and underwater ships, nuclear thermal and electric stations, research reactors and also during their repair or preservation. After fermenting of effluent, microorganisms including chlorella are cultivated in equipment desactivation chamber and by their surface they adsorb radionuclides, thus reducing radioactive background of equipment. Microorganisms with high coefficient of accumulation are separated in microfilter. Part of microorganisms is disintegrated in centrifugal disintegrator in which due to hydrodynamic, cavitation and thermal action, capsules of cells of microorganisms are destructed with release of physiologically active matters which are actually biostimulators in desactivation. Surplus part of microorganisms is subjected to pyrolysis at temperature of 500 to 600 C, and thus created solid waste is sent for further utilization. EFFECT: high efficiency. 1 dwg
