PROBLEM TO BE SOLVED: To provide a contaminated water purification system by which an operator can safely perform operation, and which is capable of removing radioactive substances of a plurality of nuclides from water contaminated by a plurality of types of radioactive substances.SOLUTION: A contaminated water purification system comprises: feeders (4A,4C) which feed materials that crystallize (insolubilize) contaminant (nuclide) to be removed; and coagulation apparatuses (coagulative separation tanks 5A,5B) which coagulate the crystallized (insolubilized) contaminants (nuclides), in which a plurality of the feeders and the coagulation apparatuses are arranged in series. 【課題】作業員が安全に作業を行なうことが出来て、且つ、複数種類の放射性物質で汚染されている汚染水から複数核種の放射性物質を除去することが出来る汚染水浄化システムの提案。【解決手段】除去するべき汚染物質（核種）を析出する（不溶化する）材料を供給する供給装置（４Ａ、４Ｃ）と、析出した（不溶化した）汚染物質（核種）を凝集する凝集装置（凝集分離槽５Ａ、５Ｂ）を備え、前記供給装置と凝集装置を直列に複数段配置したことを特徴としている。【選択図】図１
