FIELD: physics.
SUBSTANCE: method for nonchemichal waste water purification is an acoustic coagulation and subsequent gravitational deposition of the predominantly coarse suspended solids in the main sump and in the first additional sump, an acoustic coagulation and subsequent gravitational deposition of the predominantly fine suspended solids in the second additional sump and the third additional sump, an acoustic coagulation and subsequent gravitational deposition of the predominantly colloidal particles, heavy metals and salts, an acoustic precipitate seal with the use of hydro-acoustic waves of sound and ultrasonic frequencies with the sound pressure amplitude not less than, respectively, 101 PA and 102 PA at the distance of 1 m from the corresponding hydro-acoustic transducer, the upper and the lower sump section blocks of the rough water purification are used as the main sump and the first additional sump, respectively, the cascade sump of the fine water purification is used as the second additional sump, the surface filtration fields are used as the third additional sump, the acoustic coagulation is carried out only in the running hydro-acoustic waves of the sound and ultrasonic frequency ranges, additionally, the acoustic coagulation and subsequent gravitational deposition of the suspended solids, colloidal particles, heavy metals and salts are carried out in the third additional sump.
EFFECT: improving the quality of the wastewater purification.
