Claims (10)

1. Способ деконтаминации среды, содержащей порошковый материал, загрязненный одной или несколькими разновидностями органических веществ или одной или несколькими разновидностями металлов, отличающийся тем, что он включает в себя операции обработки массы этой среды при помощи процесса, при котором разрушается органический загрязнитель или загрязнители, а также обработки при воздействии микробных агентов, с последующей обработкой полученной при помощи микробов серной кислотой, с переводом при этом в раствор и выщелачиванием разновидностей металлов в виде сульфатов металлов, а также операцию обработки выщелаченных сульфатов металлов биоосаждением, при котором указанный сульфат преобразуется в нерастворимый сульфид или сульфиды.1. The method of decontamination of a medium containing powder material contaminated with one or more types of organic substances or one or more types of metals, characterized in that it includes the processing of the mass of this medium using a process in which the organic pollutant or pollutants are destroyed, and also processing under the influence of microbial agents, followed by processing obtained with the help of microbes with sulfuric acid, with the transfer into solution and leaching of various metal in the form of metal sulfates, as well as the operation of processing leached metal sulfates by biodeposition, in which said sulfate is converted to insoluble sulfide or sulfides. 2. Способ по п. 1, отличающийся тем, что сульфид водорода, полученный в ходе биоосаждения, отделяют от нерастворимых сульфидов металлов. 2. The method according to p. 1, characterized in that the hydrogen sulfide obtained during biodeposition is separated from insoluble metal sulfides. 3. Способ по п. 2, отличающийся тем, что сульфид водорода окислен в виде повторно используемого источника, содержащего серу ингредиента. 3. The method according to p. 2, characterized in that the hydrogen sulfide is oxidized in the form of a reusable source containing sulfur of the ingredient. 4. Способ по одному из пп. 1-3, отличающийся тем, что на первом этапе процесса, когда органические загрязнители подвергаются биодеструкции при помощи микробов, ранее указанной обработки кислотой, рН загрязненной среды поддерживают в диапазоне от 5 до 9. 4. The method according to one of paragraphs. 1-3, characterized in that at the first stage of the process, when organic pollutants are biodegradable using microbes, previously indicated acid treatment, the pH of the contaminated medium is maintained in the range from 5 to 9. 5. Способ по п. 4, отличающийся тем, что указанные органические загрязнители разлагают также под действием полученной микробиологически серной кислоты на второй стадии процесса. 5. The method according to p. 4, characterized in that these organic pollutants are also decomposed under the action of microbiologically obtained sulfuric acid in the second stage of the process. 6. Способ по одному из пп. 1-5, отличающийся тем, что указанная среда содержит такой порошковый материал, как грунт, частицы породы, осадок, грунт от драги, пульпу, технологический осадок, шлаки от пиролитического процесса и печную пыль. 6. The method according to one of paragraphs. 1-5, characterized in that the said medium contains such powder material as soil, rock particles, sediment, soil from dredge, pulp, technological precipitate, slag from the pyrolytic process and furnace dust. 7. Способ по одному из пп. 1-6, отличающийся тем, что указанные разновидности металлов включают в себя радиоактивные разновидности или разновидности тяжелых металлов. 7. The method according to one of paragraphs. 1-6, characterized in that these types of metals include radioactive varieties or varieties of heavy metals. 8. Способ по пп. 6 и 7, отличающийся тем, что указанная среда содержит грунт, который обрабатывают на месте нахождения загрязнений. 8. The method according to PP. 6 and 7, characterized in that the said medium contains soil, which is treated at the location of the contaminants. 9. Способ по пп. 1-8, отличающийся тем, что этапы обработки металлов в процессе протекают циклически, причем повторно используемый источник содержащего серу ингредиента микробиологически преобразуют в серную кислоту для повторного применения в той же самой среде. 9. The method according to PP. 1-8, characterized in that the stages of metal processing in the process proceed cyclically, and the reused source of sulfur-containing ingredient is microbiologically converted to sulfuric acid for reuse in the same medium. 10. Способ по п. 9, отличающийся тем, что указанное микробиологическое преобразование в серную кислоту осуществляют на месте нахождения загрязнения в подлежащей обработке среде. 10. The method according to p. 9, characterized in that the microbiological conversion to sulfuric acid is carried out at the location of the contamination in the medium to be treated.
