Zusammenfassung:	Disclosed are a method for preparing photocatalyst beads, and a photocatalytic filter comprising the photocatalyst beads. Specifically, the method for preparing photocatalyst beads, according to the present disclosure, comprises the steps of: preparing a titanium dioxide (TiO2) powder and water in a drum contained in a granulator for preparing photocatalyst beads; stirring the titanium dioxide powder and water by rotating, in a first direction, an impeller contained in the granulator; and forming a plurality of photocatalyst beads, obtained through granulation of the titanium dioxide powder, by rotating, in a second direction that is opposite to the first direction, the drum contained in the granulator during stirring of the titanium dioxide powder and water. L'invention concerne un procédé de préparation de billes de photocatalyseur, et un filtre photocatalytique comprenant des billes de photocatalyseur. Plus particulièrement, le procédé de préparation de billes de photocatalyseur, selon la présente invention, comprend les étapes consistant à : préparer une poudre de dioxyde de titane (TiO2) et de l'eau dans un tambour contenu dans un granulateur pour préparer des billes de photocatalyseur ; agiter la poudre de dioxyde de titane et l'eau par rotation, dans une première direction, d'une hélice contenue dans le granulateur ; et former une pluralité de billes de photocatalyseur, obtenue par granulation de la poudre de dioxyde de titane, par rotation, dans une seconde direction qui est opposée à la première direction, du tambour contenu dans le granulateur pendant l'agitation de la poudre de dioxyde de titane et de l'eau. 광촉매 비드(bead)의 제조 방법 및 광촉매 비드를 포함하는 광촉매 필터가 개시된다. 구체적으로, 본 개시에 따른 광촉매 비드의 제조 방법은 광촉매 비드를 제조하기 위한 제립기에 포함된 드럼 내에 이산화타이타늄(titanium dioxide, TiO 2) 분말 및 물을 준비하는 단계, 제립기에 포함된 임펠러를 제1 방향으로 회전하여 이산화타이타늄 분말 및 물을 교반하는 단계 및 이산화타이타늄 분말 및 물을 교반하는 동안, 제립기에 포함된 드럼을 제1 방향과 반대 방향인 제2 방향으로 회전하여 이산화타이타늄 분말이 과립화된 복수의 광촉매 비드를 형성하는 단계를 포함한다.
