Process for microbial in-situ remediation for the sustainable immobilization of inorganic pollutants in polluted waters

摘要

The invention describes a method for microbial in-situ remediation for the sustainable immobilization of inorganic pollutants in contaminated waters by stringing together and controlling activated natural mineral formation processes by in-situ treatment and in-situ remediation of the polluted waters and the surrounding aquifer areas and zones, as well as the recovery residues by metered introduction of a buoyant reactive material, consisting of a buoyant solid carrier material in the form of a foam glass base body with a silicate coating of hydrogen-releasing and / or sulfate-reducing substances and at least one additive, as bulk material and / or by controlled flushing in as a solid-water mixture for influencing the turnover of indigenous sulfate-reducing microorganisms and for the formation of pyrites and iron oxides. With the help of the invention, an effective, cost-effective and low-device method for microbial in-situ remediation is developed, which controls the immobilization of the pollutants by stringing together and controlling activated natural mineral formation processes, guarantees long-term effective in-situ cleaning and negatively influences the natural hydro- and geochemical conditions and disturbances in groundwater, surface water and the environment are significantly reduced and prevented in the long term, and already mobilized inorganic pollutants are immobilized in the source of the damage itself.
