Нефтезагрязненные грунты предварительно экструдируют до размера 1-8 мм, обжигают экструдаты в окислительных условиях при избытке воздуха в диапазоне температур 600-700°С в течение 0,5-1 ч с получением огарка (Т). Перколяционным методом из огарка на первой стадии выщелачивают сначала кальций, затем барий и радий водными растворами гидроксида натрия - 8-15 г/дми динатриевой соли этилендиаминтетрауксусной кислоты - 20-50 г/дм(Ж). Процесс ведут при рН 10-12, температуре 20-25°С, объемном отношении Ж:Т=3:1, с получением нерадиоактивного технического грунта и маточных растворов выщелачивания. Из маточного раствора первой стадии выщелачивания осаждают кальций в виде CaSO⋅2НО серной кислотой при рН 3,5-4,0. Из маточного раствора второй стадии выщелачивания осаждают барий и радий в виде Ba(Ra)SOсерной кислотой при рН 6,0-7,0. Образованные пульпы поступают на раздельную фильтрацию осадков в виде нерадиоактивного CaSO⋅2HO и радиоактивного Ba(Ra)SO. Регенерацию нерадиоактивных фильтратов проводят раздельно. Регенерированный раствор возвращают в оборотный цикл 3-5 раз на стадии выщелачивания. Изобретение позволяет повысить эффективность способа, обеспечивающего снижение уровня средней удельной активности нефтезагрязненных грунтов до значений, при которых они могут быть применены при рекультивации территорий. 1 з.п. ф-лы, 5 табл.

Abstract: FIELD: carbon composite materials. 
     SUBSTANCE: invention relates to carbon composite materials, products from which are intended for the aerospace and chemical-metallurgical industries, operating at high temperatures in non-oxidizing environments. A method of manufacturing products from a carbon-carbon composite material in the form of a shell, including the formation of a framework of a volumetric structure from carbon fibers by working it out on a forming mandrel installed in a circular weaving machine and saturating it with pyrocarbon from the gas phase, consists in the fact that the working time of the framework and its saturation are carried out on the same forming mandrel made of heat-resistant material with a separating layer formed on it. Newsprint, cellophane, graphite foil, and a coating of heat-resistant low-permeability material are used as the material of the separating layer. The forming mandrel is made of a material with a CTE exceeding the CTE of the formed carbon-carbon composite material. In the manufacture of products of a conical or ogival shape, the frame is fixed on a mandrel by making a cylindrical section or a section with a reverse taper on it from the side of the larger diameter or with pins made of heat-resistant material.
