CONTAMINATED WATER TREATMENT FACILITIES AND CONTAMINATED WATER TREATMENT METHOD

To provide contaminated water treatment facilities that reduce leakage of radiation from a treatment tower by a shield body that is easily assembled and disassembled at low cost and a contaminated water treatment method.SOLUTION: Contaminated water treatment facilities include a treatment tower 20 through which contaminated water containing radioactive substances is passed, and a plurality of shielding bodies 30 laminated along a longitudinal direction of the treatment tower 20 and covering the treatment tower 20. The shielding body 30 has a vessel unit 31 arranged so as to surround a periphery of the treatment tower 20 and a shielding material 33 for radiation stored in the vessel unit 31. A contaminated water treatment method includes a step of laminating a plurality of shielding bodies 30 having a vessel unit 31 arranged so as to surround a periphery of the treatment tower 20 and a shielding material 33 of radiation stored in the vessel unit 31 along a longitudinal direction of the treatment tower 20 and covering the treatment tower 20, and a step of passing the contaminated water through the treatment tower 20 covered with the shielding body 30 to perform processing.SELECTED DRAWING: Figure 7 【課題】低コストで組立及び解体が容易な遮蔽体によって処理塔内からの放射線の漏洩が低減される汚染水処理設備及び汚染水処理方法を提供する。【解決手段】汚染水処理設備は、放射性物質を含有する汚染水が通水される処理塔２０と、処理塔２０の長手方向に沿って積層されて処理塔２０を覆う複数の遮蔽体３０とを備え、遮蔽体３０は、処理塔２０の周囲を囲むように配置される容器部３１と、容器部３１に収容された放射線の遮蔽材３３とを有する。汚染水処理方法は、処理塔２０の周囲を囲むように配置される容器部３１と、容器部３１に収容された放射線の遮蔽材３３とを有する複数の遮蔽体３０を、処理塔２０の長手方向に沿って積層して処理塔２０を覆う工程と、遮蔽体３０で覆われた処理塔２０に汚染水を通水して処理する工程とを含む。【選択図】図７
