Abstract

[PROBLÈMES] Même les eaux usées propres contaminent une rivière propre une fois qu'elles sont déchargées dans la rivière. Pour résoudre ce problème, on vise à hautement purifier les eaux usées déchargées avec un appareil pour hautement purifier les eaux usées avec l'utilisation d'une route de poisson formée par un banc d'oxydation par contact. [MOYENS POUR RÉSOUDRE LES PROBLÈMES] Des barrages mobiles sont disposés sur les côtés droit et gauche des deux extrémités amont et aval d'un banc d'oxydation par contact poreux, qui est situé en continu dans la direction longitudinale d'une rivière ayant des eaux usées déchargées ou un mélange contenant des eaux usées déchargées, et les barrages mobiles en amont et en aval sont actionnés de façon alternée. Ainsi, une grande quantité des eaux usées déchargées est purifiée par perméation. Dans certains cas, un grand nombre d'appareils ci-dessus sont alignés en longueur ou en largeur et actionnés de façon répétée de telle sorte qu'un blocage peut être empêché et d'excellentes qualités d'eau peuvent être conservées. Étant donné que les eaux usées déchargées sont purifiées avec cet appareil en tirant profit de l'énergie naturelle, aucun frais d'exploitation n'est requis pour traiter l'eau. De plus, la boue formée en tant que sous-produit du traitement de l'eau est traitée dans le cycle écologique naturel et l'huile et le limon déchargés peuvent également être purifiés, ce qui contribue à l'amélioration du goût des poissons et des crustacés.
