Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and an apparatus for purification of contaminated water which enable efficient and easy removal of contaminants from large volumes of contaminated water and substantially reduce energy consumption necessary for purification of contaminated water.SOLUTION: A purification method of contaminated water comprises setting a specified area in a contaminated water area, forming a closed area A by enclosing the specified area with a water-impermeable partition wall (bank protection 2, wave removal bank 3, silt fence 6), arranging a partition wall 8 in the closed area A to form a circulation path 9 for contaminated water 7 circulating around the partition wall 8 and arranging a laminar flow generator 10 in the circulation path 9 to cause the contaminated water 7 in the circulation path 9 to circulate at a low speed so as to make contaminants in the contaminated water 7 adsorbed on a contaminant adsorption screen 19 arranged in the circulation path 9. 【課題】大容量の汚染水から汚染物質を効率よく、簡単に除去することができるとともに、汚染水の浄化に要するエネルギー消費を著しく低減することができるようにした汚染水の浄化方法および浄化装置を提供する。【解決手段】汚染された水域に一定のエリアを定めて、その周囲を非通水性の隔壁(護岸２、波除堤３、シルトフェンス６)をもって囲むことにより、閉鎖エリアＡを形成し、この閉鎖エリアＡ内に仕切壁８を配設することにより、仕切壁８の周囲を循環する汚染水７の循環路９を形成し、循環路９内に、層流発生装置１０を配設することにより、循環路９内の汚染水７を低速で循回させ、循環路９内に配設した汚染物質吸着スクリーン１９に、汚染水７中の汚染物質を吸着させる。【選択図】図１
