METHOD FOR BURIAL OF LIQUID EFFLUENTS IN GEOLOGICAL ENVIRONMENT Russian patent published in 2020 - IPC B65G5/00 G21F9/24 

FIELD: chemistry.

SUBSTANCE: invention relates to environmental protection, in particular to burial of liquid effluents in geological environment. Initially, extraction is carried out in the geological environment of areas having a developed system of open fractures, having hydrodynamic permeability and presence of a mechanism of downward filtration of fluids. Then, drilling is performed to these areas of pumping wells and pumping of waste water through these wells. At that, extraction in the geological environment of the areas with downward filtration of fluids includes establishment of areas of volcanic rock massif having open active fracture. In the selected areas with downward filtration of fluids from above the depositing cover, represented by sedimentary rocks, adjoins the underlying mass of volcanites, and open acting fracture connects sedimentary cover with bulk of volcanites. Selected areas with downward migration of fluids are analyzed by sampling cores and, if necessary, artificially increasing permeability of said areas around existing fracture.

EFFECT: higher efficiency of burial of liquid effluents in geological environment.
