FIELD: waste water purification. SUBSTANCE: purification process is conducted on worked out after petroleum products sorption schungite, which has been subjected to steam-gas activation in fluidized bed using live jet at 500-860 C for 8-10 min. As steam- gas agent, a mixture of steam with carbon dioxide at ratio at most 1:1 is utilized. EFFECT: increased process input; excluded use of expensive sorption component. 1 cl, 1 tbl, 2 ex

Изобретение относится к области очистки промышленных, сточных, ливневых и других вод от нефтепродуктов. Сущность изобретения: очистку вод проводят на отработанном после сорбции нефтепродуктов шунгите, подвергнутом в процессе регенерации парогазовой активации в режиме слоя, взвешенного острой струей при температуре 500-860oС в течении 8-10 мин. В качестве парогазового активирующего агента используют смесь водяного пара с диоксидом углерода в соотношении не более 1:1. Способ позволяет повысить производительность процесса и исключить использование дорогостоящего сорбционного компонента.The invention relates to the field of purification of industrial, waste, storm and other waters from oil products. The essence of the invention: water purification is carried out on spent schungite after sorption of oil products, subjected to steam-gas activation during regeneration in the layer mode, weighed by a sharp stream at a temperature of 500-860 o C for 8-10 minutes As a steam-gas activating agent, a mixture of water vapor with carbon dioxide in a ratio of not more than 1: 1 is used. The method allows to increase the productivity of the process and to eliminate the use of an expensive sorption component.
