    • The invention relates to a method and a device for purifying liquid effluents, in which water is separated from substances by performing, in a single vertical enclosure (3), a vertical bubbling in the effluents fed at a flow rate d. The enclosure has a free surface and includes at least two compartments (4, 5, 6, 7) communicating together for enabling a circulation between the compartments successively from the top to the bottom and from the bottom to the top between the lower portion thereof and a medium level at a flow rate D at least three times higher than the flow rate d. The supernatant phase is continuously discharged and a hydraulic or gaseous chemical oxidation of said effluents is simultaneously carried out in the same enclosure, the chemical oxidation rate and the bubble flow rate and size being selected in order to progressively obtain a separation of the solid/liquid and liquid/liquid phases at the surface of the enclosure for obtaining a COD below a predetermined threshold.
    • 本发明涉及一种用于净化液体流出物的方法和装置,其中通过在单个垂直外壳(3)中进行水的分离,在流速d进料的流出物中垂直鼓泡。 外壳具有自由表面,并且包括至少两个连通在一起的隔室(4,5,6,7),用于使得隔间之间从顶部到底部以及底部之间的下部和下部之间循环。 流量D的中等水平比流速d至少高三倍。 上清相连续排出,同时在相同的外壳中同时进行所述流出物的水力或气态化学氧化,选择化学氧化速率和气泡流速和尺寸,以便逐渐获得固体/液体的分离 以及在壳体表面处的液/液相以获得低于预定阈值的COD。
