〔産業上の利用分野〕
本発明は、被処理流体中に酸化チタンの粒子を
浮遊させると共に光を照射して、酸化チタンの酸
化力により被処理流体を清浄化し、その清浄化し
た被処理流体から酸化チタンの粒子を分離する流
体浄化方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention involves suspending particles of titanium oxide in a fluid to be treated and irradiating it with light to clean the fluid to be treated using the oxidizing power of titanium oxide. The present invention relates to a fluid purification method for separating titanium oxide particles from the cleaned fluid to be treated.
さらに詳しくは、酸化チタン（TiO2）に光を
照射するとTiO2に電子正孔が生じ、この電子正
孔が強い酸化力を有することを利用して、被処理
流体の殺菌、BOD低下、脱臭、脱色などの浄化
処理を行う方法の改良に関する。 More specifically, when titanium oxide (TiO 2 ) is irradiated with light, electron holes are generated in TiO 2 , and by utilizing the strong oxidizing power of these electron holes, it is possible to sterilize, lower BOD, and deodorize the fluid to be treated. , relates to improvements in methods for performing purification treatments such as decolorization.
従来、TiO2の粒子の全てを個々に分散した状
態で被処理流体中に浮遊させていた。
Conventionally, all of the TiO 2 particles were individually dispersed and suspended in the fluid to be treated.
しかし、TiO2は微粒子化するほど酸化力が強
くなるので、例えばTiO2を0.1μｍ以下の超微粒
子にすると、清浄化した被処理流体からの超微粒

処理が不可能であり、逆に、流体の連続浄化処理
を可能にするために、TiO2を被処理流体からの
分離が容易なかなり大きい粒子にすると、TiO2
の酸化力が弱くなつて浄化効率が低下する欠点が
あつた。
However, as TiO 2 becomes finer particles, its oxidizing power becomes stronger. For example, if TiO 2 is made into ultrafine particles of 0.1 μm or less, it becomes impossible to separate the ultrafine particles from the cleaned fluid to be treated. On the contrary, in order to enable continuous purification treatment of fluids, TiO 2 is made into fairly large particles that are easy to separate from the fluid to be treated.
The drawback was that the oxidizing power of the gas was weakened, resulting in a decrease in purification efficiency.
本発明の目的は、TiO2を微粒子化して効率良
く浄化処理を行え、しかも、TiO2の分離を容易
化して浄化処理を連続的に行えるようにする点に
ある。 An object of the present invention is to make TiO 2 into fine particles so that the purification process can be performed efficiently, and to facilitate the separation of TiO 2 so that the purification process can be performed continuously.
本発明の特徴手段は、被処理流体に浮遊させる
TiO2を超微粒子（望ましくは0.1μｍ以下）にし

多孔状の塊り（望ましくは２〜1000μｍ）にする
ことにあり、その作用効果は次の通りである。
The characteristic means of the present invention is to suspend the fluid in the fluid to be treated.
The purpose of this is to make TiO 2 into ultrafine particles (preferably 0.1 μm or less) and make many of the ultrafine particles into a porous mass (preferably 2 to 1000 μm) using a transparent substance. is as follows.
つまり、TiO2を光照射に伴つて強い酸化力を
発揮する超微粒子にして多孔状の塊りにしてある
から、個々の超微粒子と被処理流体との接触を、
超微粒子が被処理流体中に個々に浮遊している場

物質であるから、超微粒子の全てに十分に光を照
射でき、したがつて、TiO2の超微粒子による強
い酸化力を十分に活用して、効率良好な被処理流
体の浄化処理を行える。
In other words, since TiO 2 is made into a porous mass of ultrafine particles that exhibit strong oxidizing power when irradiated with light, contact between individual ultrafine particles and the fluid to be treated is prevented.
It is possible to perform the process in a state similar to when ultrafine particles are individually suspended in the fluid to be treated, and since the binder that aggregates the ultrafine particles is a translucent material, the ultrafine particles Light can be irradiated sufficiently on all the parts, and therefore, the strong oxidizing power of the ultrafine particles of TiO 2 can be fully utilized to efficiently purify the fluid to be treated.
また、超微粒子の多数を塊りにしてあるから、
TiO2の清浄化した被処理流体からの分離を、例
えばフイルターやサイクロン等の分離機で容易確
実に行え、TiO2を分離しながらの被処理流体の
連続的浄化処理を行える。 Also, since many ultrafine particles are lumped together,
TiO 2 can be easily and reliably separated from the cleaned fluid to be treated using a separator such as a filter or a cyclone, and the fluid to be treated can be continuously purified while separating TiO 2 .
その結果、従来不可能であつた、TiO2の超微

技術分野において大きく貢献できるようになつ
た。
As a result, it has become practically possible to continuously perform highly efficient fluid purification using ultrafine particles of TiO 2 , which was previously impossible, and to utilize TiO 2 in an excellent state both in terms of efficiency and efficiency. It has become possible to put fluid purification into practical use, making it possible to make significant contributions to technical fields such as water treatment and air purification.
