Summary:PROBLEM TO BE SOLVED: To provide: a closed type culture system capable of reducing running cost by reducing used amount of water quality regulator (ORP regulator) and extending a use period of active carbon; and a purification method of culture water.SOLUTION: The closed type culture system 1 has a culture water tank 2 for culturing fish and shellfish and an ozone treatment part 4 for decomposing and removing ammonia contained in culture water 3 extracted from the culture water tank 2. The closed type culture system 1 includes an active carbon treatment part 5 which reduces oxidation-reduction potential (ORP) of the culture water 3 increased by the ozone treatment through treatment with active carbon. 【課題】水質調整剤（ＯＲＰ調整剤）の使用量を削減するとともに、活性炭の使用期間を延長することにより、ランニングコストを低減させることができる閉鎖型養殖システム、及び養殖水の浄化方法を提供すること。【解決手段】魚介類を養殖する養殖水槽２と、前記養殖水槽２から抜き出した養殖水３に含まれるアンモニアを分解除去するオゾン処理部４とを有する閉鎖型養殖システムであって、前記養殖水槽２から抜き出した前記養殖水３をオゾン処理した後、活性炭により処理することによって前記オゾン処理により上昇した前記養殖水３の酸化還元電位（ＯＲＰ）を低下させる活性炭処理部５を備えることを特徴とする閉鎖型養殖システム１である。【選択図】図１
