FIELD: physics.
SUBSTANCE: invention relates to physics and can be used: for reagentless treatment of recycled industrial water (IW) from saponite-containing particles and reagentless sealing of saponite-containing precipitate; for reagentless treatment of waste IW of suspended substances in sumps and in surface filtration fields. Method consists in using at least one of depositing map bounded at all sides with waterproof dams: external, internal and two side ones, part of tailing pond with bottom inclined towards water intake, forming, amplification and emitting of travelling hydroacoustic waves in audible and ultrasonic frequency bands with amplitude of acoustic pressure no less than 102 Pa at distance of 1 m from corresponding hydroacoustic emitter, impact on industrial water with travelling hydroacoustic waves in audible and ultrasonic frequency bands in area of industrial water discharge and in central part – on path of industrial water moving to area of water intake, hydroacoustic coagulation of saponite-containing particles in area of industrial water discharge and in central part, hydroacoustic degassing of industrial water in central part and in area of industrial water discharge on depositing map, sealing of saponite-containing sediment in area of industrial water discharge and in central part, hydroacoustic sealing of bodies of all waterproof dams. Cleaning is performed in moving flow of industrial water. Emitting of travelling hydroacoustic waves in audible and ultrasonic frequency bands is carried out in pulsed and continuous mode. Additionally in area of industrial water discharge and in central part of depositing map hydroacoustic deposition of source and previously acoustically coagulated saponite-containing particles is performed by directed downward emitting of travelling hydroacoustic waves in audible and ultrasonic frequency bands. In area of industrial water discharge on depositing map hydraulic deposition of saponite-containing particles moving in industrial water flow at bottom of upper part of depositing map is performed by means of their physical engagement with saponite-containing already located at bottom. Method additionally uses sump with its inputs connected to outputs of all depositing maps, and output of which is connected to input of concentration plant.
EFFECT: fast and high-quality division of two phases – liquid and solid ones, high quality of enrichment, reduced wear of equipment using simple method with minimum financial and time costs to provide medical human safety and environmental safety of natural medium as whole.
