FIELD: technological processes.
SUBSTANCE: invention can be used in diamond mining industry during extraction of diamonds, for reagent-free treatment of saponite-containing waste quarry, waste and drainage water, for compaction of saponite-containing sediment in settling tanks, sediment collectors, in compartments of secondary settling of surface filtration fields, for preliminary preparation of drinking water and compaction of bodies of water-resistant dams. Method of reagentless purification of saponite-containing water and compaction of saponite-containing sediment involves use of at least three deposition beds KN-1, KN-2, KN-3, dump of pulp to corresponding accumulation map KN-1, KN-2, KN-3 through concentrated 6 and distributed 5 releases, hydroacoustic action on saponite-containing water and on saponite-containing sediment with hydroacoustic waves of sound and ultrasonic frequency bands. Free end of concentrated outlet 6 is equipped with a flexible abrasive-resistant branch pipe, by means of which the angle of pulp discharge is changed by at least 30 degrees once a day to the corresponding deposition map KN-1, KN-2, KN-3. Distributed outlets 5 are oriented at angle of 60 degrees upwards. Perform hydroacoustic preliminary cleaning of saponite-containing water, hydroacoustic seal of saponite-containing sediment, hydroacoustic deposition of initial and previously hydroacoustic coagulated saponite-containing sludge particles. Compartment of finally cleaned saponite-containing water 15 is arranged. Additionally, acoustic sedimentation of initial and previously hydroacoustically coagulated saponite-containing sludge particles is performed by radiation from air to water at an angle of not more than 15 degrees down acoustic waves of sound and ultrasonic frequency bands with amplitude of acoustic pressure of not less than 1 Pa at distance of 1 m from the corresponding acoustic radiator.
EFFECT: invention enables efficient cleaning of saponite-containing effluents, compacting saponite-containing precipitate using the entire volume of the tailing dump, providing safety for maintenance personnel and the environment.
