The two reactors were packed with biomass carriers consisting of different configurations of the same acrylic-fiber material: a net-type carrier biofillR (BL) in the AF reactor and a multi-directional thread-type carrier biofringeR (BF) in the SB reactor. The system was operated continuously under various organic loading rates (OLRs) from 1.5 to 4.5 kg COD m-3 d-1 and nitrogen loading rates (NLRs) from 0.1 to 0.3 kg N m-3 d-1 using moderately high-strength synthetic wastewater. The AF reactor, located upstream of the SB reactor, provided hydrolysis, fermentation and anaerobic ammonification. During 184 days of operation, stable total nitrogen (TN) removal efficiencies ranging from 85% to 97% were obtained primarily due to SND in the SB reactor when the OLR was higher than 2.7 kg COD m-3 d-1. In addition, observed sludge yields for the whole system ranged from 0.13 to 0.17 kg MLSS kg-1 CODremoved; furthermore, mixed liquor suspended solids (MLSS) were maintained at about 10,000 mg l-1 in the SB reactor. Exceptionally high COD and TN removal rates of 5.9 kg COD m-3 d-1 and 0.43 kg N m-3 d-1, respectively, were observed in the SB reactor. These results demonstrated that excess sludge reduction and SND could be achieved concurrently by this combined AF-SB system.","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本水処理生物学会"}]},"item_16_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.2521/jswtb.45.123","subitem_relation_type_select":"DOI"}}]},"item_16_relation_16":{"attribute_name":"情報源(ISSN)","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"09106758"}]}]},"item_16_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2009 by Japanese Society of Water Treatment Biologyer Treatment Biology"}]},"item_16_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00351126","subitem_source_identifier_type":"NCID"}]},"item_16_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"518","subitem_subject_scheme":"NDC"}]},"item_16_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"2100866 bytes"}]},"item_16_text_38":{"attribute_name":"別言語の出版者","attribute_value_mlt":[{"subitem_text_value":"Japanese Society of Water Treatment Biology"}]},"item_16_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_16_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_16_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_16_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"01"}]},"item_16_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"徐, 暁晨"}],"nameIdentifiers":[{"nameIdentifier":"105314","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金, 虎"}],"nameIdentifiers":[{"nameIdentifier":"105315","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小山, 登一郎"}],"nameIdentifiers":[{"nameIdentifier":"105316","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古川, 憲治"}],"nameIdentifiers":[{"nameIdentifier":"105317","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-03-02"}],"displaytype":"detail","filename":"JSWTB_45_3_2009_123-136.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JSWTB_45_3_2009_123-136.pdf","url":"https://kumadai.repo.nii.ac.jp/record/23897/files/JSWTB_45_3_2009_123-136.pdf"},"version_id":"e27c0848-1e86-4afe-a656-dba33ef66378"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"IFAS","subitem_subject_scheme":"Other"},{"subitem_subject":"biofringe","subitem_subject_scheme":"Other"},{"subitem_subject":"SND","subitem_subject_scheme":"Other"},{"subitem_subject":"excess sludge reduction","subitem_subject_scheme":"Other"},{"subitem_subject":"swim-bed","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Simultaneous Nitrification and Denitrification with Excess Sludge Reduction in an Attached Growth System Combining Anaerobic Fermrntation and Aerobic Swim-bed Processes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Simultaneous Nitrification and Denitrification with Excess Sludge Reduction in an Attached Growth System Combining Anaerobic Fermrntation and Aerobic Swim-bed Processes","subitem_title_language":"en"}]},"item_type_id":"16","owner":"1","path":["428"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-09"},"publish_date":"2010-11-09","publish_status":"0","recid":"23897","relation_version_is_last":true,"title":["Simultaneous Nitrification and Denitrification with Excess Sludge Reduction in an Attached Growth System Combining Anaerobic Fermrntation and Aerobic Swim-bed Processes"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-19T13:42:32.059412+00:00"}
