[Problem] To make it possible to easily attach and detach a measurement device to tunnel construction equipment. [Solution] An attachment/detachment device 1 comprises: a support body 4 that supports a measurement device 3; an adhesion means 10 which is provided on the back side of the support body 4 and attaches to tunnel construction equipment 2; and an extension body 5 which extends from one side of the support body 4 to the outside in the horizontal direction. The extension body 5 is provided with a fixed part 11 which is fixed to the support body 4, an outside part 12 which extends from the fixed part 11 towards the outside of the support body 4 in the horizontal direction, and an inside part 13 which extends from the fixed part 11 towards the inside of the support body 4 in the horizontal direction. If the outside part 12 of the extension body 5 is raised towards the surface side of the support body 4 while in a state in which the support body 4 has been fixed to the tunnel construction equipment 2 via the attachment means 10, the inside part 13 of the extension body 5 tips over towards the back side of the support body 4 and one side of the support body 4 floats up, releasing the support body 4 from the tunnel construction equipment 2.
[Problem] To provide a filtration device, a filtration system, and a filtration method highly effective in removing a persistent substance. [Solution] A filtration device 10 according to the present invention comprises: a filtration container 11 having a supply port 4 for a liquid A to be treated and a discharge port 15 for a treated liquid B; and a tubular filtration filter 12 which is provided inside the filtration container 11 and in which an outer surface 12f is a filtration surface and the interior is a passage for the treated liquid B, wherein in the state before filtration, an adsorbent N that adsorbs the persistent substance E is laminated on the outer surface 12f of the filtration filter 12 and forms an adsorbent layer 47.
