Claims (12)

1. Сыпучий дисперсный материал для использования в обработке сточных вод, отличающийся наличием гранул пластмассы, каждая из которых содержит множество зерен по существу инертного минерала, нанесенного на нее для получения среды обитания для микроорганизмов, эффективных при обработке сточных вод, причем гранулы имеют заданный диапазон размеров частиц, а зерна имеют заданный диапазон размеров частиц и расположены на гранулах с заданным диапазоном плотности заполнения.1. Bulk dispersed material for use in wastewater treatment, characterized by the presence of granules of plastic, each of which contains many grains of a substantially inert mineral deposited on it to obtain a habitat for microorganisms effective in treating wastewater, and the granules have a given size range particles, and grains have a given range of particle sizes and are located on granules with a given range of filling density. 2. Сыпучий дисперсный материал по п.1, отличающийся тем, что частицы имеют среднюю плотность примерно 1,0 г/см3, так что часть этих частиц может плавать, а часть может тонуть в обрабатываемых сточных водах.2. The bulk dispersed material according to claim 1, characterized in that the particles have an average density of about 1.0 g / cm 3 so that some of these particles can float and some can sink in the treated wastewater. 3. Сыпучий дисперсный материал по п. 1 или 2, отличающийся тем, что примерно 50% частиц может плавать вблизи поверхности массы обрабатываемых сточных вод, а примерно 50% может тонуть после начальной загрузки и при нахождении массы сточных вод в состоянии покоя. 3. The bulk dispersed material according to claim 1 or 2, characterized in that about 50% of the particles can float near the surface of the treated wastewater mass, and about 50% can sink after the initial loading and when the wastewater mass is at rest. 4. Материал по любому из пп.1-3, отличающийся тем, что он имеет удельную площадь поверхности, превышающую примерно 600 м2 на кубический метр сыпучего материала.4. The material according to any one of claims 1 to 3, characterized in that it has a specific surface area exceeding about 600 m 2 per cubic meter of bulk material. 5. Материал по любому из пп.1-4, отличающийся тем, что он имеет диапазон размеров частиц по существу 4 - 6 мм диаметром. 5. The material according to any one of claims 1 to 4, characterized in that it has a particle size range of essentially 4-6 mm diameter. 6. Материал по любому из пп.1-5, отличающийся тем, что песок присоединен к гранулам полиэтилена. 6. The material according to any one of claims 1 to 5, characterized in that the sand is attached to the granules of polyethylene. 7.

The method according to any one of claims 7 to 9, characterized in that the granules are contacted with the mixture at an elevated temperature, so that the grains cover the granules, largely immersed in the partially molten outer surface of the granules, while at the stage of dissolving the grains of the soluble substance depressions remain on the surface of the granules. 11. Способ обработки сточных вод, отличающийся тем, что сточные воды и сыпучий дисперсный материал по любому из пп.1-6 загружают в резервуар для обработки и проводят газификацию сточных вод и дисперсного материала пузырьками газа, выделяемого из одного или более газификаторов, расположенных в нижней части резервуара для обработки. 11. A method of treating wastewater, characterized in that the wastewater and bulk particulate matter according to any one of claims 1 to 6 are loaded into a treatment tank and gasification of the wastewater and particulate material is carried out with gas bubbles generated from one or more gasifiers located in bottom of the processing tank. 12. Устройство для обработки сточных вод, отличающееся тем, что оно включает резервуар для обработки, содержащий сыпучий дисперсный материал по любому из пп.1-6, один или более газификаторов, расположенных в нижней части резервуара для обработки, и средства подачи газа в газификаторы для выделения в виде пузырьков газа для газификации дисперсного материала и сточных вод. 12. A device for treating wastewater, characterized in that it includes a treatment tank containing granular particulate material according to any one of claims 1 to 6, one or more gasifiers located in the lower part of the treatment tank, and means for supplying gas to gasifiers for allocation in the form of gas bubbles for the gasification of dispersed material and wastewater.
