FIELD: chemistry.
SUBSTANCE: invention relates to purification of sewage waters and drinking water from radionuclides and chemical elements and can be used for purification of liquid radioactive wastes of nuclear power plants (NPP), decontamination of ground water and drinking water reservoirs, purification of technological solutions and sewage waters of industrial enterprises, as well as in systems of water treatment plants and water preparation. Device for purification of sewage waters and drinkable water from radionuclides and harmful chemical elements contains framework, in which cylindrical units with filtering and sorbing materials, connected with joining pipes, input and output connecting pipes are successively located one after another. To regenerate filtering and sorbing materials with ultrasound units are installed coaxially inside cylindrical magnetostrictive transducers, which from one side are connected to generators of ultrasonic oscillations, supplied to unit with filtering material in form of quartz sand with frequency 18-20 kHz, on unit with sorbing material in form of glauconite granules with frequency 27-30 kHz, and from the other side magnetostrictive transducers are connected via waveguides with emitters, made in form of cylinders and coaxially placed inside units.
EFFECT: increase of device service, increased degree of purification from radionuclides and harmful chemical elements.
