Abstract

The present invention relates to a water purifier of a type employing stepping-stones coated with titanium dioxide, whereby water-treatment efficiency is improved through the use of the oxidizing power of titanium dioxide and an internal biofilm carrier. The present invention improves on the treatment efficiency of prior-art processing methods in that the powerful oxidising action of titanium dioxide only takes place on the surface and is not persistent and hence there is no effect on microorganisms or the like.

Description

징검다리형 수질정화기Stepping Bridge Water Purifier
본 발명은 이산화티타늄이 징검다리형 박스의 표면에 코팅되고, 상기 박스의 빈 공간에는 구(球, Ball) 형상의 생물막 담체(2)들이 채워져서 구성된 징검다리형 수질정화기에 관한 것으로, 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-purifying device comprising a titanium dioxide coated on the surface of a box-type box and filled with a ball-shaped biofilm carrier (2) in an empty space of the box. It can be used for water purification, including lake purification or wastewater, and it can be configured as a stepping bridge to obtain eco-friendly visual effects.
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 for applying titanium to a specific object, Korean Patent Publication No. 10-1999-0022798 (purification and purification device for purification) (published on March 25, 1999), etc., which applies titanium 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.

400㎚)의 UV를 조사할 경우 TiO2전자는 Valence band에서 Conduction band로 전이가 일어나게 되고 이로 인하여 Valence band에서 hole이 생성된다. 이렇게 생성된 전자와 hole은 TiO2 표면으로 확산 이동하게 된다. 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 소비하여 Recombination을 방지하여 OH 라디칼의 생성을 증가시키며 광촉매반응에서 OH 라디칼과 O22- 라디칼은 유기물질을 산화시키는 산화제로 사용된다.
The present invention uses the oxidation of titanium dioxide in order to increase the water treatment efficiency and the wavelength (TiO 2) has a band gap energy on the surface (

In the case of UV irradiation of 400nm), TiO 2 electrons are transferred from the valence band to the conduction band, thereby creating holes in the valence band. The generated electrons and holes diffuse to the TiO 2 surface. The water adsorbed on the TiO 2 surface or OH - and the hole reaction may generate OH radicals and, in the case of oxygen present in the water has to generate more OH radicals generated by the O 2 2- radical reacts with the e-TiO 2 Organic substances on the surface are decomposed, which is called photocatalytic reaction. OH radicals and O 2 2- radicals are also produced by H 2 O 2 , which is produced as an intermediate of the reaction. H 2 O 2 , HO 2 and O 2 consume the generated electrons to prevent recombination and increase the production of OH radicals. In photocatalytic reactions, OH radicals and O22- radicals are used as oxidants to oxidize organic materials.
