METHOD decontamination of soils contaminated by petroleum products, OF electrohydraulic impact

摘要

1. A method for decontamination of soil contaminated with oil, with the electro-pin, characterized in that the soil contaminated with oil, loaded into a suction filter heated EDM type, then poured into the filter tap water preheated to 90 ° C, in a ratio of: 1 part of soil contaminated with oil 2 parts tap water, whereupon the agitator is activated and the mixture was stirred for 5 min, then the mixture was filtered, the filtrate is drained into a collection vessel and allowed to settle for s 1 hour to achieve separation of the oil and aqueous phases, the aqueous phase separated in the separation process, decanted, is brought to the volume required for washing portionwise addition of water, is heated to a temperature up to 90 ° C and sent to the EDM filter for repeated washing soil contaminated petroleum products, are then repeated stirring and filtering operations after filtration primer with a reduced content of oil loaded in the installing electro shock reactor equipped with a device for bubbled anija air, and subjected to extreme processing and hydroacoustic nanoimpulsnymi combined electrostimulation (EHP) with a purge vozduhom.2. A method according to claim 1, characterized in that the mode setting EHP: voltage 20 kV; 40.3 the number of pulses. A method according to claim 1, characterized in that the filtrate obtained after the second wash is combined with the decanted oil phase obtained after the first washing, carefully mixed and fed into a flow reactor installation electrohydraulic pin provided with a device for
