摘要： Even if ozone and hydrogen peroxide solution are simply mixed with water to be treated to perform oxidative destruction of harmful substances, such as dioxins, PCB and the like, it is difficult to decompose the harmful substances, with desired decomposing effects. It is an object of the present invention to provide an advanced water treatment process and system which are based on ozone treatment capable of providing more reliable treatment effects. To attain the above object, according to the present invention, ozone treatment is carried out in which minute bubbles of ozone having an average particle diameter of 0.5 to 3 mu m are brought into contact with water to be treated, which contains the harmful substances, such as dioxins and PCB. By carrying out a desired combination of the ozone treatment as an essential treatment, and a hydrogen peroxide treatment, an ultraviolet radiation treatment, an electrolysis treatment, and a carbonized filter medium treatment, it is possible to realize enhanced effectiveness of the water treatment.

摘要翻译： 即使将臭氧和过氧化氢溶液与待处理的水简单混合来进行有害物质如二恶英，PCB等的氧化破坏，也难以分解所需的分解效果的有害物质。 本发明的目的是提供一种基于能够提供更可靠的处理效果的臭氧处理的先进的水处理过程和系统。 为了实现上述目的，根据本发明，进行臭氧处理，其中平均粒径为0.5〜3μm的臭氧的微小气泡与含有有害物质的被处理水接触， 如二恶英和PCB。 通过进行作为必要处理的臭氧处理和过氧化氢处理，紫外线照射处理，电解处理和碳化过滤介质处理的期望组合，可以实现水处理的有效性的提高。
