Abstract
(EN)
A wastewater treatment equipment in which wastewaters containing organic matter are treated by micronanobubbles in micronanobubble reaction vessel (3) and thereafter introduced in aerating tank (7). Consequently, prior to the treatment with microbes having their activity enhanced in the aerating tank (7), the wastewaters containing organic matter are treated by micronanobubbles to thereby accomplish partial oxidation of the organic matter contained in the wastewater with the micronanobubbles with the result that the organic matter load is reduced. Thereafter, the treated water is introduced in the aerating tank (7) in which by means of submerged membrane (17), microbes are present in high concentration to thereby accomplish effective disposal of the organic matter. Through miniaturization of the aerating tank (7), there can be accomplished reduction of the scale of whole equipment and reduction of initial cost. In photocatalyst tank (22) arranged downstream of the aerating tank (7), high-level oxidation of a minute amount of organic matter unaffected by the microbial treatment alone can be carried out by oxidation by means of photocatalyst plate (24).

L’invention concerne un équipement de traitement des eaux usées dans lequel les eaux usées contenant des matières organiques sont traitées à l’aide de micronanobulles dans un récipient de réaction à micronanobulles (3) avant introduction dans un réservoir d’aération (7). Ainsi, avant traitement à l’aide de microbes dont l’activité est renforcée dans le réservoir d’aération (7), les eaux usées contenant des matières organiques sont traitées à l’aide de micronanobulles pour ainsi accomplir l’oxydation partielle des matières organiques contenues dans les eaux usées avec les micronanobulles avec pour conséquence de réduire la charge des matières organiques. Ensuite, on introduit les eaux traitées dans le réservoir d’aération (7) dans lequel grâce à une membrane immergée (17), les microbes sont présents dans une concentration élevée pour ainsi accomplir l’enlèvement effectif des matières organiques. La miniaturisation du réservoir d’aération (7) permet de réduire l’échelle de l’équipement dans son ensemble et d’abaisser les coûts initiaux. Dans un réservoir de photocatalyseur (22) disposé en aval du réservoir d’aération (7), on peut réaliser une très forte oxydation d’une quantité minime de matières organiques non affectées par le traitement microbien seul, par oxydation à l’aide d’une plaque photocatalysatrice (24).

この排水処理装置は、マイクロナノバブル反応槽3で有機物含有排水をマイクロナノバブルで処理してから、曝気槽7に導入する。これにより、曝気槽7での微生物の活性を高めて処理する前に、有機物含有排水をマイクロナノバブルで処理し、排水中の有機物をマイクロナノバブルで一部酸化し、有機物負荷を低減した後、液中膜17によって微生物濃度が高濃度に存在している曝気槽7に処理水を導入して効果的に有機物を処理できる。曝気槽7の小型化を図れて装置全体の規模の縮小化を図れ、イニシャルコストの削減を図れる。また、曝気槽7の後段の光触媒槽22では、光触媒板24による酸化処理によって微生物処理だけでは不可能な微量の有機物の高度な酸化処理を行える。
