    摘要： Toxic PCB has been broadly used as insulating oil in electric equipment such as capacitors, transformers and the like. Since the PCB is a refractory organic compound, the disposal of PCB is not advanced until now. This is a great social problem in Japan and the world. Thus, the early disposal of PCB is demanded.
    The conventional PCB disposing systems include a burnout type high-temperature disposing system and a chemical decomposing system. However, the high-temperature burning system is not satisfactorily improved due to various problems such as a difficulty of control for a furnace, a problem of disposing the ash containing non-decomposed PCB, a problem of generation of dioxin in lower processing temperature, a problem of movement of the PCB and a problem of not obtaining the agreement of inhabitants. Moreover, the chemical decomposing system raises various other problems in that a plant must be constructed with a huge investment that is said to be equal to 40 hundred millions per plant, that PCB must be transported to the PCB disposing plant and that the PCB disposing speed in the plan is too slow.
    The present invention provides a novel PCB electrolyzing and disposing method and apparatus based on a new idea in which the PCB used as electrically insulating oil can be electrolyzed by passing the electricity through the PCB. The PCB disposing apparatus of the present invention may be portable. Thus, the apparatus can be moved to any PCB storage place to dispose the PCB in place without transportation of the PCB. In addition to the introduction of the PCB into an electrolyzing tank, the PCB may be electrolyzed by pouring water into the container of equipment containing the remaining PCB, inserting the inserting portion including the electric-wave rod, electrode rods and others into the water to electrolyze the PCB. A PCB-polluted container may be placed in a large-sized disposing tank for electrolysis.
    The system of the present invention may be used as a soil improving apparatus by placing PCB- or dioxin-polluted soil in a disposing tank and electrolyzing the PCB or dioxin therein.
    The apparatus of the present invention may be manufactured in smaller to larger sizes, depending on processing scale, and may be manufactured as a portable apparatus, as a large-scaled plant or as an integral unit mounted on a vehicle. Moreover, the system of the present invention can dispose the PCB with a greatly reduced cost and in an increased speed, in comparison with the prior art. According to the present invention, the disposal of PCB can be sharply be accelerated in Japan and the world.

    摘要翻译： 有毒的PCB已广泛用作诸如电容器，变压器等的电气设备中的绝缘油。 由于PCB是难熔有机化合物，因此PCB的处理在现在尚未发展。 这是日本乃至全世界极大的社会问题。 因此，要求早日处理PCB。 传统的PCB布置系统包括烧录型高温处理系统和化学分解系统。 然而，由于炉子的控制困难，处理含有未分解的PCB的灰分，在较低的加工温度下产生二恶英的问题，存在的问题，高温燃烧系统不能令人满意地改善， PCB的流动问题和未获得居民同意的问题。 此外，化学分解系统引起了各种其他问题，因为一个工厂必须建设一个巨大的投资，据说相当于每个工厂4亿个，PCB必须运输到PCB处理厂，并且PCB处理速度 在计划中太慢了。 本发明提供了一种基于新的思想的新型PCB电解和布置方法和装置，其中用作电绝缘油的PCB可以通过使电流通过PCB来电解。 本发明的PCB布置装置可以是便携式的。 因此，该装置可以移动到任何PCB存储位置以将PCB布置在适当位置，而不需要输送PCB。 除了将PCB引入电解槽之外，PCB可以通过将水倒入容纳剩余PCB的设备的容器中来进行电解，将包括电波棒，电极棒等的插入部分插入水中 电解PCB。 PCB污染的容器可以放置在用于电解的大型处理罐中。 本发明的系统可以通过将PCB-或二恶英污染的土壤放置在处理槽中并在其中电解PCB或二恶英来用作土壤改良装置。 本发明的装置可以根据加工规模制造成更小尺寸更大的尺寸，并且可以作为大型工厂的便携式装置或安装在车辆上的整体式单元来制造。 此外，与现有技术相比，本发明的系统可以以大大降低的成本和增加的速度来布置PCB。 根据本发明，日本和世界可以大幅度加快对PCB的处置。

    摘要： A first electrolytic chamber which houses an anode plate and a cathode plate with an ion-permeable membrane interposed therebetween is supplied with raw water containing an electrolyte as chloride ions. The raw water is electrolyzed to obtain electrolyzed water at a cathode side in the first electrolytic chamber. The electrolyzed water is then electrolyzed at an anode side in a second electrolytic chamber which houses an anode plate and a cathode plate with an ion-permeable membrane interposed therebetween, for thereby generating hydroxyl radicals in the electrolyzed water. The electrolyzed water containing the hydroxyl radicals is added to water containing an organic substance to cause the hydroxyl radicals to attack to the organic substance for thereby decomposing the organic substance.
