。In order to achieve the above object, in the present invention, in a multi-stage solid-liquid contact device that brings a particulate adsorbent into contact with a liquid, a plurality of solid-liquid contact towers without an adsorbent support plate filled with particulate adsorbents are arranged in a horizontal direction. Arranged in series, the bottom of the contact tower and the top of the adjacent contact tower are connected by piping so that the treatment liquid is sequentially introduced from the bottom of the plurality of contact towers and discharged from the top,
The present invention provides a multi-stage solid-liquid contact device characterized in that a pressure water injection facility is provided in the final contact tower of the contact tower, and an adsorbent discharge pipe is provided at the bottom of the first contact tower. In a multi-stage solid-liquid contact method in which a liquid is treated with a granular adsorbent, a plurality of solid-liquid contact towers without a support plate are arranged in series in the horizontal direction, the contact tower is filled with granular adsorbents, and the treated liquid is sequentially applied. Water is introduced from the bottom of the contact tower and discharged from the top for treatment. If the adsorption capacity of the adsorbent decreases, the introduction of the treated liquid is stopped and pressurized water is introduced into the final contact tower to improve the flow of water in the contact tower. This is a multi-stage solid-liquid contact method characterized in that the adsorbent is transferred in the opposite direction to the treatment liquid and sequentially guided to the preceding contact tower, and the adsorbent of the first contact tower is extracted from the bottom of the contact tower.

It flows into the second adsorption tower 5 via piping 4, fluidizes the activated carbon 6 with an upward flow, flows into the third adsorption tower 8 through piping 7, comes into contact with activated carbon 9, and then passes through piping 10. The treated water then flows into the treated water receiving tank 11. When 1 raw water is flowing, valve 15.1
6.17 is closed, and valve 13.14 is open.
活性炭の排出、移送、補給は次の工程に従って行われる

For smooth transfer, it is preferable to use activated carbon of 8 meshes or less. In addition, powdered activated carbon is
It is preferable not to use it because it becomes compacted when it is at rest and loses its fluidity.
