摘要： The present invention relates to an apparatus including a pressure layer having an ability of following up the deformation or movement of a packed bed of a solid catalyst and/or solid adsorbent which is provided on the packed bed. Specifically, the present invention relates to an apparatus in which a pressure layer having an ability of following up the deformation of the top surface of the solid catalyst packed bed is provided on the packed bed, or in which a water-permeable pressure layer having an ability of following up the deformation of the solid catalyst packed bed is provided on the packed bed. Such pressure layers are effective in sufficiently preventing the solid catalyst from moving in the packed bed. As a result, there is no problem such as the abrasion of solid catalyst mainly caused by its movement, the deterioration of the performance thereof, and an increase in pressure loss, thereby treating waste water in a stable manner for a long period of time.

摘要： An apparatus for treating waste water, characterized in that a pressure layer capable of following up the deformation or a movement of a surface of a packed bed of a solid catalyst and/or a solid adsorbent is provided on the packed bed. More particularly, an apparatus provided with a pressure layer, which has a capability of following up a movement of a surface of such a packed bed as mentioned above, on the packed bed, or an apparatus provided with a water-permeable pressure layer, which has a capability of being deformed in accordance with the deformation of a surface of such a packed bed, on the packed bed. Owing to such pressure layers, a movement of a solid catalyst in a solid catalyst packed bed is prevented effectively, and various problems which are caused mainly by a movement of the solid catalyst, such as the abrasion of the solid catalyst, the deterioration of the performance thereof and an increase in a pressure loss, can be solved. This enables the waste water to be treated stably for a long period of time.
