PROBLEM TO BE SOLVED: To provide a contaminated water processing technology capable of providing a user with a material for determining optimum replacement timing to thereby facilitate appropriate replacement of an adsorption tower.SOLUTION: A contaminated water processing system 10 include: a first reception section 21 that receives at-inlet water quality of contaminated water W which flows in an adsorption tower 11 which absorbs radioactive nuclides, an integrated flow amount of the contaminated water W and performance of an adsorbent 13 filled in the adsorption tower 11 as a first index quantity L; an outlet water quality estimation section 24 that estimates a variation with time of outlet water quality of treated water Wwhich flows out from an outlet 23 of the adsorption tower 11 from the first index quantity L as an outlet water quality function; an adsorption amount estimation section 25 that estimates a variation with time of the adsorption amount of radioactive nuclides of the adsorbent 13 based on the first index quantity L as an adsorption distribution function; and a first calculation section 29 that calculates replacement timing P based on at least one of the outlet water quality function and the adsorption distribution function and an existing replacement threshold value H.
