1. a kind of method of the ultrasound-enhanced reparation of a kind of organic contamination place soil, it is characterised in that use organic contamination placeThe prosthetic appliance of soil, contaminated soil is put into bucket (3), is driven by motor and is crushed slurry to soil progress crushed work, led toCross high-pressure hydraulic pump (2) water in aqua storage tank (1) is pumped into bucket (3), after soil is crushed, open bucket bottom valve (4), mudWater mixed liquid enters high-speed stirred grinder (5), drives stirring slurry in rotating shaft to be stirred operation by stirring motor, realizes muddy waterIt is sufficiently mixed, later on supersonic generator (9), ultrasonic wave brings into operation, ultrasonic time 60 minutes, ultrasonic power1200W, stir speed (S.S.) is 300r/min;

  • By the mud mixture of ultrasonic wave-Zero-valent Iron processing, mud is pumped into by sludge pump (6)Aqueous phase after water separation device (7), separation of solid and liquid enters aqua storage tank (1) by circulating line, realizes can be recycled for water,Mud after being dehydrated through sludge-water separating system can be in outdoor natural air drying;

    When the ultrasonic wave brings into operation, into muddy water mixed solutionZero-valent Iron is added, the consumption of Zero-valent Iron is 300g/50kg soil;

    In the muddy water mixed solution, water and soil mass ratio is 3:

    1, can1,2,4- trichloro-benzenes is removed completely;

    A kind of prosthetic appliance of described organic contamination place soil, including the storage being sequentially connectedTank (1), high-pressure hydraulic pump (2), bucket (3), valve (4), high-speed stirred grinder (5), sludge pump (6), device for separating mud and water(7) and water circulating pipe, wherein aqua storage tank (1) is connected by high-pressure hydraulic pump (2) with bucket (3), bucket (3) and high-speed stirring breadingValve (4) is provided between millstone (5), high-speed stirred grinder (5) is connected by sludge pump (6) with device for separating mud and water (7),Ultrasonic wave vibration plate (8) is arranged on the inner side of high-speed stirred grinder (5) outer wall, ultrasonic wave vibration plate (8) and supersonic generator (9)It is connected, the delivery port of device for separating mud and water (7) is connected by water circulating pipe with aqua storage tank (1), by device for separating mud and water(7) aqueous phase of separation directly can enter aqua storage tank (1) by water circulating pipe;

    The aqua storage tank (1) locates below ground level;

    Also wrapAutomaton is included, for automatically controlling the unlatching of supersonic generator (9) and high-speed stirred grinder (5), closing.
