Abstract

La présente invention a pour objet un dispositif d'injection d'un gaz dans un liquide s'écoulant dans un canal. Elle est caractérisée en ce que le canal comporte au moins une tubulure fermée, qui est reliée par l'intermédiaire d'un raccord à gaz à un appareil d'alimentation en gaz et dans laquelle il est prévu un distributeur de gaz, pénétrant le cas échéant dans le liquide en écoulement dans le canal et pouvant être sorti tout en maintenant l'écoulement du liquide dans le canaL Elle se rapporte à l'épuration d'eaux d'égout.The present invention relates to a device for injecting a gas into a liquid flowing in a channel. It is characterized in that the channel comprises at least one closed pipe, which is connected by means of a gas connection to a gas supply apparatus and in which there is provided a gas distributor, penetrating the case. in the liquid flowing in the channel and can be taken out while maintaining the flow of the liquid in the channel It relates to the purification of sewage.
