METHOD OF BURYING OF LIQUID INDUSTRIAL WASTES Russian patent published in 1995 - IPC

FIELD: burying of industrial wastes and sewage waters. SUBSTANCE: chosen is synclinal structure formed by alternating permeable and tight layers containing ³He and ⁴He ratio 10^-5-10^-7. Then injection and check wells are drilled. Pumped into permeable layer are industrial wastes with density not less than density of natural brine in selected synclinal structure. In process of pumping and storage of industrial wastes state of geological section is checked additionally by revealing the changes in background concentration of helium isotopes and/or ion-salt complexes inherent to synclinal structure in upper water-bearing levels above storage. EFFECT: enhanced reliability of storage. 4 tbl
