FIELD: technological processes.
SUBSTANCE: invention relates to a method for reagentless treatment of mine water, which consists in hydroacoustic action on the treated mine water and on the compacted sediment by alternating: pulsed - with duration of less than 1 s, quasi-pulse - with duration from 1 s to 10 s and continuous - with duration of more than 10 s, waves of sound and ultrasonic frequency ranges in series-functionally connected: in the first, in the second, in the third, in the fourth and in the fifth, elements of the mine water treatment system, in acoustic coagulation of colloidal particles, suspended substances and heavy metals, in gravitational and gravitational-acoustic sedimentation on the bottom of previously acoustically coagulated colloidal particles, suspended substances and heavy metals, in acoustic compaction of sediment with its subsequent periodic extraction and disposal at the solid waste storage landfill, wherein the sound pressure amplitude of the sound and ultrasonic frequency ranges is not less than 104 Pa at distance of 1 m from the corresponding hydroacoustic radiator, first element used is identical to each other section water collectors located on sections of mine, as the second element, identical to each other main water collectors are used, located in the near-shaft yard of the mine, as the third element, identical to each other settling ponds are used, as the fourth element, identical to each other filter chambers are used, as the fifth element, identical filters are used, additionally performing electrochemical coagulation of colloidal particles, suspended substances, heavy metals and disease-causing bacteria in the near field of hydroacoustic emitters in the process of converting electrical energy into acoustic energy, additionally, deposition of previously coagulated colloidal particles, suspended substances, heavy metals and pathogenic bacteria is carried out under the action of acoustic waves of sound and ultrasonic frequency ranges with sound pressure amplitude of 1 Pa at distance of 1 m from the corresponding acoustic radiator, directed from the air under the water at angle of 25 degrees, further cleaning from the pathogenic bacteria in the near field of the hydroacoustic radiators is carried out with the emission of acoustic waves with a sound pressure amplitude of 104 Pa, additionally, in the fifth element, previously coagulated colloidal particles, suspended substances, heavy metals and pathogenic bacteria are extracted on filters.
EFFECT: disclosed is a method for reagentless treatment of mine water.
