Description
본 발명은 이산화티타늄이 징검다리형 박스의 표면에 코팅되고, 상기 박스의 내부 빈 공간에는 구(球, Ball) 형상의 생물막 담체(2)들이 채워져서 구성된 징검다리형 수질정화기에 관한 것으로서, 하천 및 호수정화 또는 폐수 등을 포함한 수질정화에 이용할 수 있으며, 징검다리 형태로 구성하여 친환경적인 시각적 효과도 얻을 수 있다.The present invention relates to a water-refining purifier comprising titanium dioxide coated on a surface of a water-containing box, and filled with a ball-
본 발명은 징검다리형 수질정화기에 관한 것이다. 티타늄을 특정의 물체에 도포하는 기술로는 한국 공개특허공보 제10-1999-0022798호(정화용 부침체 및 정화장치)(1999.03.25.공개) 등이 있으나, 이는 볼의 외부에 티타늄을 도포하고 내부에는 원통형으로 구멍을 내어 광촉매 반응을 일으키는 방법으로서, 정화용 부침체가 광촉매 반응만을 일으키는 단점이 있다.The present invention relates to a stepping-type water purifier. As a technique of applying titanium to a specific object, there is a Korean Patent Publication No. 10-1999-0022798 (purification and purification device for purification) (published on March 25, 1999), etc., this is applied to the outside of the ball As a method of causing a photocatalytic reaction by drilling a hole in a cylinder, there is a disadvantage in that the purifying submerged body causes only a photocatalytic reaction.
본 발명은 수처리에 있어 이산화티타늄의 산화력과 내부의 생물막 담체를 이용하여 수처리 효율을 높이는 징검다리형 수질정화기에 관한 것이다. 이산화티타늄에 의한 강한 산화작용은 징검다리형 박스의 표면에서만 일어나고 잔류성이 없기 때문에 미생물에 미치는 영향 등은 없어 기존 처리방식의 처리효율을 향상시킨다.The present invention relates to a stepping-type water purifier for improving water treatment efficiency by using the oxidation power of titanium dioxide and the internal biofilm carrier in water treatment. The strong oxidation effect of titanium dioxide occurs only on the surface of the stepping box and there is no residual effect, so there is no effect on microorganisms, thus improving the treatment efficiency of the existing treatment method.
본 발명은 수처리효율을 높이기 위하여 이산화티타늄의 산화작용을 사용하며 TiO2 표면에 Band gap 이상의 에너지를 가지는 파장(λ< 400nm)의 UV를 조사할 경우 TiO2 전자는 Valence band에서 Conduction band로 전이가 일어나게 되고 이로 인하여 Valence band에서 hole이 생성된다. 이렇게 생성된 전자와 hole은 TiO2 표면으로 확산 이동하게된다. TiO2 표면에 흡착된 물이나 OH- 과 hole이 반응하여 OH 라디칼을 생성하기도 하며 수중에 존재하는 산소의 경우에는 전자와 반응하여 O2 2 - 라디칼을 생성하여 더 많은 OH 라디칼을 생성시켜 TiO2 표면의 유기물질 등을 분해하게 되는데 이를 광촉매 반응이라고 한다. OH 라디칼과 O2 2 - 라디칼은 또한 반응의 중간생성물로 생성되는 H2O2 에 의해서도 생성된다. H2O2, HO2, O2 는 생성된 전자를 소비하 여 Recombination을 방지하여 OH라디칼의 생성을 증가시키며 광촉매반응에서 OH 라디칼과 O2 2 - 라디칼은 유기물질을 산화시키는 산화제로 사용된다.The present invention uses the oxidation of titanium dioxide to increase the water treatment efficiency and when TiO 2 surface is irradiated with UV of wavelength (λ <400nm) with energy above the band gap, TiO 2 electrons are transferred from the conductance band to the conduction band. This causes holes in the valence band. The generated electrons and holes are TiO 2 Will diffuse and move to the surface. TiO 2 Water adsorbed on the surface or OH - and the hole reacts to produce OH radicals, and in the case of oxygen present in water, it reacts with electrons to generate O 2 2 - radicals to generate more OH radicals to form TiO 2 Organic substances on the surface are decomposed, which is called photocatalytic reaction. OH radicals and O 2 2 - radicals are also H 2 O 2 generated as intermediates of the reaction It is also generated by H 2 O 2 , HO 2 , O 2 Consume the generated electrons to prevent recombination and increase the production of OH radicals. In photocatalytic reactions, OH radicals and O 2 2 - radicals are used as oxidants to oxidize organic materials.
또한 상기 수질정화 목적을 달성하기 위하여 생물막을 사용하여 수질정화 효과를 더욱 높인다.In addition, in order to achieve the above-mentioned water purification purpose, using a biofilm further enhances the water purification effect.
본 발명을 이용하여 이산화티타늄의 산화작용을 수처리에 효율적으로 이용할 수 있으며, 이는 수질정화 효과 뿐만 아니라 시각적 효과도 이룰 수 있다.By using the present invention, the oxidation of titanium dioxide can be efficiently used in water treatment, which can achieve not only a water purification effect but also a visual effect.
