| description | A method for reusing wastewater by using reverse osmosis, according to the present invention, provides a method for preparing pure water through a primary reverse osmosis step, a secondary reverse osmosis step, a foam generation step, and a reverse osmosis membrane washing step. The present invention prepares pure water through several reverse osmosis steps, thereby enabling prepared pure water to be immediately used as industrial water, and washes a reverse osmosis membrane with foam, thereby improving washing efficiency and saving on maintenance costs of a wastewater reuse apparatus.
Selon la présente invention, un procédé de recyclage d'eaux usées par osmose inverse fournit un procédé de préparation d'eau pure par une étape d'osmose inverse primaire, une étape d'osmose inverse secondaire, une étape de génération de mousse et une étape de lavage de membrane d'osmose inverse. La présente invention prépare de l'eau pure au moyen de plusieurs étapes d'osmose inverse, permettant ainsi à l'eau pure préparée d'être immédiatement utilisée en tant qu'eau industrielle, et lave une membrane d'osmose inverse avec de la mousse, ce qui permet d'améliorer l'efficacité de lavage et d'économiser des coûts de maintenance d'un appareil de recyclage d'eaux usées.
본 발명에 의한 역삼투를 이용한 폐수 재이용 방법은 1차 역삼투 단계, 2차 역삼투 단계, 기포 발생 단계, 역삼투막 세정 단계를 통해 순수를 제조하는 방법을 개시한다. 본 발명은 여러 단계의 역삼투 공정에 의해 순수를 제조함으로써, 제조된 순수를 곧바로 공업용수로 사용할 수 있으며, 기포에 의해 역삼투막을 세정함으로써, 세정 효율이 향상되고, 폐수 재이용 장치의 운영비용이 절감되는 효과가 있다. |
