摘要： PROBLEM TO BE SOLVED: To provide an oil recovery apparatus capable of remarkably enhancing the reduced quantity of oil included in soil irrespective of oil kind, contamination form, contamination history or else and reducing the load of water treatment by efficiently recovering the oil separated from soil particles.
SOLUTION: Oil/water separation is efficiently performed in such a manner that a slurry 40 in a tank main body 30 is circulated by a circulation pump 13, fine air bubbles are added into the circulated slurry 40 by using a fine air bubble generator 14, the slurry is injected in the tangential direction of the inner peripheral surface of the tank main body 6 and in the same direction through slurry supply pipes 8a, 8b and, thereby, a swirl flow is imparted to the slurry 40 in the tank main body 6. Oil separating working is performed efficiently. The separated oil floats up to the water surface while swirling and the floating oil is accumulated to the central part having a lower water level and deposited along an oil recovery plate 16 disposed on the upper end part of an oil recovery pipe 15. When the oil 41 is deposited up to the upper end of an upper opening part 17 of the oil recovery pipe 15, the oil 41 is allowed to continuously flow into the oil recovery pipe 15 from the upper opening part 17 and is recovered by an oil recovery tank 42.

摘要： PROBLEM TO BE SOLVED: To outstandingly enhance the amount of reduced oil content contained in soil regardless of oil species, contamination form, contamination history, or the like and to efficiently recover the oil content peeled off from soil particle.
SOLUTION: In the soil washing method, 0.1-0.4% of surfactant and 10-20% of washing water in a weight ratio are added to the soil contaminated with the oil, the mixture is stirred for a constant time in the state that the moisture content against the soil is made less and the oil content is removed from the soil. When the stirring is carried out, since the moisture content against the soil is less, contact area between the soil particles of the soil is increased and friction effect becomes large. Thereby, the oil content is easily removed from the soil particles of the soil to enhance removal efficiency of the oil content.

摘要翻译：要解决的问题：无论油种，污染形式，污染历史等如何，都能显着提高土壤中所含的含油量，并有效地回收从土壤颗粒中剥离的油含量。解决方案：在土壤清洗方法中，将0.1-0.4％的表面活性剂和10-20％重量比的洗涤水加入到被油污染的土壤中，将混合物在该状态下搅拌恒定时间减少对土壤的含水量，从土壤中除去含油量。当进行搅拌时，由于对土壤的含水量较小，土壤颗粒之间的接触面积增加，摩擦效应变大。因此，容易从土壤中的土壤颗粒中除去含油量，以提高油含量的去除效率。版权所有（C）2005，JPO＆NCIPI
