FIELD: decontaminating liquid radioactive wastes by diaphragm-sorption method. SUBSTANCE: method involves pre-clarifying of slightly mineralized and slightly contaminated water in sediment tank filled with suspended crushed zeolite-production wastes. Then water is cleaned of remaining suspended substances by means of mechanical filters and ultraviolet filters with concentrated product (50-90% of water flow) returned to sediment tank followed by additional decontamination of water by means of filters with synthetic sodium zeolite. Clean water is supplied to intermediate tank and sediment containing secondary wastes is immobilized in cement. Proposed method provides for decontaminating water from beta-nuclides by 102-103 times, reducing amount of secondary wastes by 0.2% of source water volume, reducing leaching of radionuclides from solidification products to maximum 1•10-3g/cm2 a day. EFFECT: provision for waste disposal to simple burial ground. 1 dwg
