To provide an apparatus for treating a forced foaming-type organic liquid mixture treatment which is capable of a stable continuous operation free from operation stops of the apparatus caused by abnormal foaming, which is capable of treating without dilution even though it is a high concentration mixture liquid, which produces a treatment solution which is stable without rotting for a long time, which can be reused and free from secondary pollution; and a treatment method.
A liquid inlet (29) and a liquid mixture supplying valve (30) are provided at the ceiling of a foaming tank (1) having a sealed structure. From the bottom of the foaming tank (1), a foam generator (13), a foam-liquid kneader (15) and a circulation pump (16) are serially connected to the ceiling part liquid inlet (29). Also, at the lower part of the foaming tank (1), an aeration pipe (7) and an aeration blower (6) are placed. The upper part of the foaming tank (1) and the upper part of a foam receiving tank (10) having a sealed structure are connected to each other with a foam-liquid separator (8). An exhaust fan (19) is connected to the ceiling of the foam receiving tank (10) by connecting it to the foam-liquid kneader (15) via a foam supplying valve (14) from the bottom of the foam receiving tank (10).
