METHOD FOR BURIAL OF LIQUID WASTES Russian patent published in 2019 - IPC B65G5/00 E02D29/00 

FIELD: removal and processing of wastes.

SUBSTANCE: invention relates to environmental protection from wastes from urban areas that contaminate surface hydrosphere. Essence of the invention includes use for disposal of liquid wastes (effluents from urban areas) karst medium (karst massif) by pumping liquid wastes into it through wells with possible subsequent extraction and processing of accumulated volumes of substances deposited in traps (gas, oil products, metals). In practice of underground disposal of wastes, purposeful use of prepared karst medium (karst massif) for placement of wastes in it is not known. In case of using claimed technology of liquid effluents disposal one should note appearance of such very significant effects as increase of efficiency of liquid effluents location and recycling (cleaning), which is ensured by optimal length of their downward migration, physical-mechanical and chemical interaction with migration route rocks and entrapment of harmful substances by lithospheric traps.

EFFECT: higher efficiency of burial of liquid wastes (effluents) in the geological depositing medium.
