Description

폐수처리용 광촉매볼 및 볼담체의 설치구조{A installation structure of Photocatalyst ball and ball media for waste-water treatment}A installation structure of Photocatalyst ball and ball media for waste-water treatment}

본 고안은 폐수처리용 광촉매볼 및 볼담체에 관한 것으로서, 더욱 상세하게는 폐수처리에 사용되는 광촉매불 및 볼담체를 상호 결합고정한 후, 이를 소정 와이어로 연결하여 폐수처리장에 설치 및 수거가 용이하고, 세척 또한 용이하게 하여 폐수처리의 관리가 수월한 폐수처리용 광촉매볼 및 볼담체의 설치구조에 관한 것이다.The present invention relates to a photocatalyst ball and a ball carrier for wastewater treatment, and more particularly, after fixing the photocatalyst fire and the ball carrier used in the wastewater treatment, and connecting them with a predetermined wire, the wastewater treatment plant is easily installed and collected. In addition, the present invention relates to an installation structure of a photocatalyst ball and a ball carrier for wastewater treatment, which facilitates washing and also facilitates management of wastewater treatment.

일반적으로 폐수처리에는 부착식 미생물 성장에 의한 폐수처리공법이 많이 이용되는데, 이는 크게 살수여상조, 회전원판법, 침적여상조등이 있다.In general, wastewater treatment is mainly used for the treatment of wastewater by the growth of adherent microorganisms, which includes a spraying tank, a spinning disk method, and a deposition tank.

이러한 공법에는 공통적으로 미생물이 부착, 성장할 수 있는 담체가 필요하다. 일반적으로 담체의 선택은 비표면적, 공극율 단위중량, 담체의 구조나 크기 또는 비용과 같은 요소들에 의해 결정되며, 그 크기가 작을수록 미생물의 부착과 생장을 위한 표면적은 커지나 그 반면에 공극율은 줄어든다. 종래의 오ㆍ폐수처리장에서 사용되었던 담제는 미생물 초기 부착이 늦고 부착된 미생물막이 쉽게 이탈되어 슬러지가 많이 발생하였다. 그래서 슬러시 생산에 따르는 막힘현상이 많았다. 또한 유속의 영향에 따라 담체의 외부에는 생물막의 형성이 불가능하였다, 그래서 대부분 내부에만 생물막이 형성되어 폐수처리 효율면에서도 부족한 점이 많았다. 장시간 사용시 초기 효율에 비하여 현저한 감소를 보이며, 담체의 파손과 부식이 빈번하여 유지관리비용이 높았다.Such a method requires a carrier to which microorganisms can attach and grow in common. In general, the choice of carrier is determined by factors such as specific surface area, porosity unit weight, structure, size or cost of the carrier, and the smaller the size, the larger the surface area for microbial attachment and growth, while the porosity is reduced. . In the conventional sewage and wastewater treatment plant, the bile was lately attached to microorganisms and the attached microbial membrane was easily detached, resulting in a lot of sludge. Therefore, there were many blockages due to slush production. In addition, due to the influence of the flow rate, it was impossible to form a biofilm on the outside of the carrier, so most of the biofilms were formed only on the inside, which was insufficient in terms of wastewater treatment efficiency. When used for a long time, it showed a significant decrease in comparison with the initial efficiency, and the maintenance cost was high due to frequent breakage and corrosion of the carrier.

이에 본 출원인이 선출원한 특허출원 제 2001-0034255호 에서는 볼케이스 외부에 산화 촉매제인 이산환티탄을 코팅하고, 볼의 내부에는 내부 담체를 내장함으로써 단위체적 당 표면적을 극대화하여, 미생물의 부착과 폐수와의 접촉을 용이하도록 한 볼딤체를 개발하였으며, 이를 소정 프레임에 고정하여 폐수처리장의 폐수내에 침수시켜 폐수처리를 하였다.Accordingly, in the patent application No. 2001-0034255, which was filed by the applicant, the titanium dioxide cyclic catalyst, which is an oxidation catalyst, is coated on the outside of the ball case, and the inside of the ball is embedded with an internal carrier to maximize the surface area per unit volume. A ball step body was developed to facilitate contact with the wastewater, and it was fixed to a predetermined frame and submerged in the wastewater of the wastewater treatment plant to treat the wastewater.

또한, 본 출원인이 선출원한 특허출원 제 2002-0009440호 에서는 필터에 균일한 세공분포를 갖는 제올라이트 촉매를 담체로 활용하여 세공내에 광촉매를 담지시키고 PP,PE등 지지체와 혼합/사출성형하여 구형의 볼필터로 제조되는 광촉매볼을 개발하였으며, 이를 폐수의 수면위에 띄워 폐수의 휘발성 유기물질, 악취, 각종 미연소탄화수소를 제거할 수 있도록 하였다.In addition, in Patent Application No. 2002-0009440 filed by the present applicant, a photocatalyst is supported in a pore by using a zeolite catalyst having a uniform pore distribution in a filter as a carrier, and a spherical ball is mixed / injected with a support such as PP and PE. A photocatalyst ball made of a filter was developed and floated on the surface of the wastewater to remove volatile organic substances, odors, and various unburned hydrocarbons.

그러나, 일반적으로 폐수처리장에서 볼담체 및 광촉매볼을 이용하여 페수처리를 하게 될 경우 상기 볼담체를 별도의 프레임에 의해 고정하여 폐수내에 침수시켜 사용해야하며, 상기 광촉매볼은 폐수의 수면위에 다량 띄워 사용하게 되어 광촉매볼 및 볼담체를 세척 및 교체하고자 할 경우 그 작업이 장시간이 소요됨과 아울러 매우 불편하였다.In general, however, when wastewater treatment is performed using a ball carrier and a photocatalyst ball in a wastewater treatment plant, the ball carrier is fixed by a separate frame and used to be immersed in the wastewater, and the photocatalyst ball floats on the water surface of the wastewater. If you want to wash and replace the photocatalyst ball and the ball carrier it takes a long time and very inconvenient.

따라서, 폐수처리장에서 상기의 볼담체 및 광촉매볼을 사용시 그 세척 및 교체작업의 불편함으로 인해 유지비용 및 설치비용이 많이 드는 문제점이 발생되었다.Therefore, when the ball carrier and the photocatalyst ball are used in the wastewater treatment plant, problems of high maintenance and installation costs have arisen due to the inconvenience of washing and replacing.
