The device is comprised of a conventional PVC tube containing several baffle plates inside that are arranged in an alternating pattern at a 115-degree downward angle. Water enters from the top of the device and is mixed with air as it flows downward. Using this cylindrical aerator, the concentration of dissolved nitrogen was reduced from 111% to 103%, while the dissolved oxygen concentration was increased from 9.3 ppm to 10.8 ppm. These results are similar to those of conventional aeration tanks. However, the cost for constructing a new-type aerator is only 1/7 that of a conventional aeration tank.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"さけますセンターにおいて新たな曝気装置の開発に取り組んだ。曝気装置本体は既製の硬質塩化ビニル管で，内部にはじゃま板を下方向に 115 度の角度で交互に複数取り付けた。水は装置の上から入り，空気と撹拌されながら下に流れ落ちる構造である。この円筒型曝気装置を使い，用水の溶存窒素濃度が 111％から 103％に減少，溶存酸素濃度が 9.3 ppm から 10.8 ppm に増加するなどの結果が得られた。これらは従来型の曝気槽と同等の効果であった。さらに製作費用も従来型曝気槽の 7 分の 1 程度であった。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産総合研究センター","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Fisheries Research Agency","subitem_publisher_language":"en"}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_t_3_2_147","subitem_relation_type_select":"Local"}}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引（AgriKnowledge）"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010814289","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12359338","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-2253","subitem_source_identifier_type":"PISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"戸田, 修一","creatorNameLang":"ja"}],"familyNames":[{"familyName":"戸田","familyNameLang":"ja"}],"givenNames":[{"givenName":"修一","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"増川, 則雄","creatorNameLang":"ja"}],"familyNames":[{"familyName":"増川","familyNameLang":"ja"}],"givenNames":[{"givenName":"則雄","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"戸嶋, 忠良","creatorNameLang":"ja"}],"familyNames":[{"familyName":"戸嶋","familyNameLang":"ja"}],"givenNames":[{"givenName":"忠良","givenNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-08-06"}],"filename":"fra_t_3_2_147.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010498/files/fra_t_3_2_147.pdf"},"version_id":"20dc8073-4fa8-4ba5-b575-432b5907a7ac"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"サケふ化場の用水を処理する安価な円筒型曝気装置の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"サケふ化場の用水を処理する安価な円筒型曝気装置の開発","subitem_title_language":"ja"},{"subitem_title":"Development of a Low-priced Cylindrical Water Aerator for Use in Salmon Hatcheries","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085693113"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010498","relation_version_is_last":true,"title":["サケふ化場の用水を処理する安価な円筒型曝気装置の開発"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:33:59.813742+00:00"}
