Preparations for biological cleaning of soils contaminated with organochlorine compounds inherent EMISSIONS OF CHEMICAL COMPANIES

摘要

FIELD: soils treatment.; SUBSTANCE: invention relates to the preparations for the biological treatment of the soil contaminated by chloroorganic substances attributed to emissions of chemical enterprises; the preparation for the biological teatment of the soil contains glauconite substance, bioactive silt, amber acid, nitrogen-bearing biogenic element in the form of calurea and water; to stimulate the oxidation activity of microbiotas the cultural liquid of the strain of the bacteria Bacillus subtilis BAG-65 and the still residue of the chemical production containing tetrachloroethane, trichloroethene, chloroform, dichloroethane, methylene chloride and methyl chloride are additionally interposed into the preparation; the preparation components are represented in the following specific mass composition (%): glauconite substance: 65 - 70; bioactive silt: 3 - 5; amber acid: 0.01 - 0.05;nitrogen-bearing biogenic element: 0.01- 0.50; cultural liquid of the strain of the bacteria. Bacillus subtilis BAG-65: 15 - 20; tetrachloroethane: 0.27 - 0.38; trichloroethene: 0.14 - 0.16; chloroform: 0.39 - 0.42; dichloroethane: 0.24 -0.36; methylene chloride: 0.12 - 0.50; methyl chloride: 0.56 - 0.68; water: 17.26 - 1.95;; EFFECT: grown in the ferment bioactive microorganisms of certain physiological groups on the basis of the above preparation in the form of paste contribute not only to the biological treatment of the soil contaminated by chloroorganic substances but also retrieve the vigorous activity of aboriginal microbiota.;10 tbl, 1 dwg
