DEVICE AND METHOD FOR REMOVING CESIUM IN TURBID WATER

PROBLEM TO BE SOLVED: To provide a device which drastically reduces a cesium contaminated waste generated in the processing for removing cesium from turbid water containing a suspended matter that absorbs radioactive cesium.SOLUTION: A cesium in turbid water removal device according to the present invention is non-adsorptive for a suspended matter in water, and includes: a filtering body 22 containing one of non-absorptivity particles 21 which can be dispersed or the non-absorptivity filters which can be cleaned; a turbid water supply part 24 for supplying a turbid water 10 containing a suspended matter 12 that absorbs radioactive cesium into the filtering body 22; a treatment water discharge part 26 for discharging a treatment water 14 filtered by the filtering body 22; a filtering body accommodation part 28 for accommodating the filtering body 22; a treatment side net part 30 for holding the filtering body having a net finer than the non-absorptivity particles 21 and rougher than the suspended matter 12; a cleaning water supply part 32 for supplying a cleaning water 16 to the filtering body 22; and a sewage discharge part 34 for discharging a cleaned water 18 containing the suspended matter 12 that passes the treatment side net part 30.SELECTED DRAWING: Figure 1 【課題】放射性セシウムを吸着した懸濁物質を含む濁水中からセシウムを取除く処理によって生じるセシウム汚染廃棄物を大幅に減らした装置を提供する。【解決手段】本発明の濁水中セシウム除去装置は、水中懸濁物質に対して非吸着性であると共に、離散可能な非吸着性粒子２１又は洗浄可能な非吸着性フィルタの一方を含む濾過体２２と、濾過体２２に放射性セシウムを吸着した懸濁物質１２を含む濁水１０を供給する濁水供給部２４と、濾過体２２で濾過された処理水１４を排出する処理水排出部２６と、濾過体２２を収容する濾過体収容部２８と、非吸着性粒子２１よりも細かく懸濁物質１２よりも荒い網目を有する濾過体保持用の処理側網部３０と、濾過体２２に洗浄水１６を供給する洗浄水供給部３２と、処理側網部３０を通過した懸濁物質１２を含む洗浄済み水１８を排出する汚水排出部３４とを備える。【選択図】図１
