Abstract

La présente invention pourrait contribuer à résoudre le changement climatique global. Les techniques fondamentales d'extraction d'algues et d'huile sont basées sur le principe selon lequel les algues et l'huile flottent sur l'eau. De plus, les sédiments dégradés et les polluants des sols dans l'eau ont la propriété de s'élever jusqu'à la surface de l'eau en raison de la flottabilité de l'air pulvérisé. Ainsi, la présente invention implique l'aspiration et la collecte de sédiments dégradés et de polluants des sols dans l'eau avec des algues. Il est considéré qu'il est possible de réduire à un minimum la marée rouge au moyen d'un travail préliminaire en mer ou sur des côtes proches de rivières, sur des côtes de pêcheries d'aquaculture côtières où de grandes quantités d'eaux usées provenant de villes sont évacuées, etc. Seul le travail persistant des navires de collecte est considéré comme pouvant améliorer suffisamment la qualité des sols dans l'eau. Même si des navires de collecte sont répartis dans les rivières et les océans de Corée, il est considéré qu'il est possible de sauver les rivières et les océans à faible coût.
