NOVELTY - Remediation of petroleum pollution involves pouring compressed air into a tubular probe inserted in a drilling well on soil layer polluted by petroleum to fracture the soil, and repeating this step until the polluted area becomes air-fractured soil layer; removing contaminants in vapor phase by vacuum pump; uniformly distributing mineral salt liquid culture medium into the soil at 100-150 psi; and pumping continuous air flow from pump well through vacuum pump, and supplying remaining oxygen from other surrounding wells to maintain continuous oxygen supply in the soil hole.    USE - Method for remediation of petroleum pollution (claimed).    ADVANTAGE - The method saves 40-50% of investment and 20-35% of operation cost. The maintenance and management cost accounts for 40-75% of other similar technology.    DETAILED DESCRIPTION - Remediation of petroleum pollution involves:    (A) inserting a tubular probe in a drilling well on soil layer polluted by petroleum, connecting a high-pressure jet nozzle to the probe at 2-3 meters lower than the ground, pouring compressed air into the tubular probe to fracture the soil, and repeating this step until the polluted area becomes air-fractured soil layer;    (B) removing contaminants in vapor phase by vacuum pump after being fractured pneumatically;    (C) opening the high-pressure jet nozzle of pneumatic fracturing system and uniformly distributing mineral salt liquid culture medium into the soil at 100-150 psi; and    (D) arranging more than one central pump well in the polluted area, connecting the vacuum pump at the output of central pump well, pumping continuous air flow from the pump well through the vacuum pump, and supplying remaining oxygen from other surrounding wells to form air circulation to maintain continuous oxygen supply in the soil hole.    An INDEPENDENT CLAIM is included for a petroleum pollution remediation device comprising air compressor, vacuum pump, well mouth valve, three valves, high-pressure jet nozzle, dosing groove, and mixing tank. An exhaust pipe of air compressor is connected with the well mouth valve and first valve through a second valve. The vacuum pump is connected with the well mouth valve and third valve through the second valve. The other end of third valve is connected with mixing tank, and the other end of well mouth valve is connected with subsurface aluminum-plastic pipe of pneumatic fracturing well. The aluminum-plastic pipe is connected with high-pressure jet nozzle and is twice as long as ground water level. The exhaust pipe is at the same horizontal level as a pipeline which is connected with well mouth valve and third valve through second valve. The exhaust pipe is hot pot galvanizing pipe which can bear 8 atmospheric pressure and has diameter of 25 mm and wall thickness of 2.75 mm, and other pipes which are connected with air compressor, vacuum pump and well mouth valve are PVC pipes.
