SEWAGE TREATMENT PLANT FOR ATOMIC POWER STATIONS Russian patent published in 2001 - IPC

FIELD: complex biological treatment of sewage at atomic power station with channel-type high-power reactors at generation of commercial products: methane (CH₄),, protein-vitamin additive, treated water (T₂O) for electric heat generators for extreme North regions. SUBSTANCE: plant includes methane tank with acid, alkaline and methane fermentation chambers equipped with dispersers with circular passage between cylindrical surface of rotor and housing. Biogas supercharger is communicated with chlorella generator. Plant includes also centrifugal microfilter with dynamic disintegrator fitted with branch pipe for removal of disintegrate and mixture of ordinary water and deuterium water which is communicated with receiver. Hydraulic seal provided within area of branch pipes is equipped with rectification column with transversal perforated partition forming sections communicated through overflow pipes. Upper section is connected with dephlegmator by steam line and with rectification tower by phlegma through hydraulic seal. Lower section is connected with heat exchanger and with treated water receiver and with circulation loop of water-moderated water-cooled power reactor through this receiver, with circulating pump and separator. Circulation loop is communicated with additional rectification column and commercial treated water (T₂O). receiver. This plant is also used for production of heavy water through repeated partial evaporation of ordinary water and condensation of heavy water; heavy water is converted into treated water through activation in cooling loop of water-moderated water-cooled power reactor; concentration of treated water increases by 20 to 30 times as compared with standard level. EFFECT: possibility of generation of superheavy water as commercial product used as power source. 1 dwg
