凹型の反射板21bを用いると更に処理効率が向上する。FIG. 1A is a sectional view showing an example of the configuration of the device of the present invention. In the figure, reference numeral 3 denotes a processing container, 11 denotes a horn-tip type ultrasonic vibrator, 21a denotes a reflection plate, 1 denotes an inlet for a liquid to be processed, and 2 denotes an outlet for the liquid to be processed. In FIG. 1, the horn tip type ultrasonic vibrator 11 vibrates up and down, and the surface of the ultrasonic vibrator
Ultrasonic waves are generated from 11a. The generated ultrasonic traveling wave and the reflected wave from the reflecting plate 21a interfere with each other to generate a strong amplitude, which promotes a high / low density change. The liquid to be treated is efficiently treated. Further, when the distance 31a between the ultrasonic vibrator surface 11a and the reflector 21a is n · λ / 2, the amplification of the ultrasonic wave further occurs, and the treatment efficiency of the organic waste liquid is improved. However, ultrasonic waves attenuate with increasing distance,
If n is too large, that is, if the distance 31a is large, the effect of the reflector 21a cannot be sufficiently obtained. Therefore, the most preferable case is n = 1, that is, the case where the distance 31a between the ultrasonic vibrator surface 11a and the reflector 21a is λ / 2.
The shape of the reflector may be a flat shape as shown in FIG. 1A, but the shape of the reflector shown in FIG. 1B may be such that the reflected wave from the reflector 21a efficiently returns to the ultrasonic vibrator surface 11a. The use of the concave reflector 21b as shown in (1) further improves the processing efficiency.

There is some problem that cannot be done. Therefore, a barrier or the like may be provided so that the liquid to be treated does not enter the space, but the liquid to be treated can be treated more efficiently with the configuration shown in FIG. FIG. 2A shows another configuration example of the present invention, in which the inner surface of the processing container 3 is used as a reflector. Parts corresponding to those in FIG. 1 are denoted by the same reference numerals, and redundant description will be avoided. Surface of horn tip type ultrasonic vibrator
The traveling wave generated from 11a is reflected on the inner surface of the processing container [the bottom surface of the processing container 3 in FIG. 2A], and is reflected between the surface 11a of the horn-tip type ultrasonic vibrator and the inner surface of the processing container. The waves interfere with each other to generate a strong amplitude, which promotes a high density change, and the liquid to be processed in the processing container 3 is efficiently processed.

And releases it into the liquid or bath. In this case, radial components are generated inside the tubular resonators and are emitted at right angles from the walls of the respective resonators.
The longitudinal axis of the resonator is aligned with an integral multiple of the half-wavelength λ / 2 of the sound wave in order to generate a lateral contraction in the contraction oscillator of the working frequency.

し、処理容器3内の被処理液は効率良く処理される。However, as shown in FIG. 3, when the reflection plate 21 is provided in the processing container 3, a space is formed between the inner surface of the processing container 3 and the outer surface of the reflection plate 21. There is a slight problem that the liquid cannot be completely processed. Therefore, some measures may be taken, such as providing a barrier or the like so that the liquid to be treated does not enter the space.

る。When the rod-shaped ultrasonic vibrator 12 is used,
As in the wave image 41 shown in FIG. 5, the rod-shaped ultrasonic vibrator 12
Interference between adjacent waves occurs due to the transverse amplitude generated at the time of stretching vibration of the standing wave generated on the surface. That is, at the position (node) where the phase of the standing wave is reversed in the positive and negative directions, interference between adjacent waves occurs, the change in density is suppressed, and the processing efficiency deteriorates. Therefore, as shown in FIG. 5, the donut-shaped partition plate 22 is separated from the solid-shaped or hollow rod-shaped ultrasonic vibrator 12 at a position serving as a node of a standing wave, and the rod-shaped ultrasonic vibrator 12 is partitioned. If the plate is provided so as to penetrate the hollow in the vertical direction, it is possible to avoid the suppression of the change in density due to the interference between adjacent waves, and it is possible to generate a strong amplitude and increase the area where the change in density is high. As a result, the liquid to be treated can be efficiently treated. Note that the partition plate 22 is disposed at a position serving as a node of the standing wave generated in the rod-shaped ultrasonic vibrator 12, for example, when there is one node of the standing wave, the partition plate 22 is also one. Become. In addition, the partition plate 22 is ± λ / 8 from the position where it becomes a node of the standing wave.
It is preferable to arrange them so as to have the following distance. In this range, an effect of sufficiently suppressing interference between adjacent waves can be obtained.

/ 2 (36 mm), and a remarkable effect can be obtained by providing a reflector at λ / 2. Also, the distance between the surface of the ultrasonic vibrator and the reflector is 70
Even in the case of mm, a sufficient effect can be obtained, which corresponds to the case where the distance between the surface of the ultrasonic vibrator and the reflector is λ (72 mm). However, since the sound wave is strongly attenuated in water, the distance between the surface of the ultrasonic vibrator and the reflector is λ (72 m
It is better to be slightly smaller than m).
