EFFECT OF OF INITIAL COD CONCENTRATION AND AERATION CONDITION ON REMEDIATION OF SLOW-FLOW POLLUTED SURFACE WATER BY IMMOBILIZED Flavobacterium sp. 作者: Li, HB (Li, Hai-Bo)[ 1 ] ; Li, YH (Li, Ying-Hua)[ 1 ] ; Wang, H (Wang, Hong)[ 1 ] ; Sun, TH (Sun, Tie-Heng)[ 1,2 ] 來源出版物: FRESENIUS ENVIRONMENTAL BULLETIN 卷: 21 期: 12B 頁: 4016-4021 出版年: 2012 被引頻次: 0 (來自 Web of Science) 引用的參考文獻(xiàn): 21 [ 查看 Related Records ] 引證關(guān)系圖 摘要: One strain was isolated from hydrocarbon-polluted Liao River Oil field, and was representative of Flavobacterium sp. (strain Oil-56). Chitosan (CS), sodium alginate (SA) and calcium chloride (CaCl2) embedding technology was adopted for Flavobacterium sp. immobilization. Secondly, the study investigated the influence of initial chemical oxygen demand (COD) of the surface water and aeration conditions on the remediation efficiency of the immobilized microbe. The results demonstrated that the immobilized beads gave high porosity and mechanical strength, easy regeneration and a long utilization time. The immobilized Flavobacterium sp. beads made in this study were suitable for remediation of COD-contaminated surface water with a wide range of initial COD values. At initial COD 77205 mg/L, the residual COD values for immobilized cells were 38-98 mg/L after 48 h, with removal efficiencies of 48.2-50.6%, being 42.7-45.8% higher than those of the free cells. Aeration accelerated bioremediation process. The optimal aeration intensity was 120 rpm, under which the COD removal efficiencies were 82 and 28% for immobilized beads and free cells, respectively. The Scanning Electronic Microscope (SEM) analysis indicated that the bead microstructure was suitable for Flavobacterium sp. growth. 入藏號: WOS:000320829600015 文獻(xiàn)類型: Article 語種: English 作者關(guān)鍵詞: surface water; immobilized cell; COD reduction; aeration condition; SEM analysis KeyWords Plus: HEAVY-METALS; SOIL; FUNGI; BIOAVAILABILITY; BIOREMEDIATION; RADIONUCLIDES; MUSHROOMS; LEAD 通訊作者地址: Li, YH (通訊作者) Shenyang Agr Univ, 21 Wanghua South St, Shenyang 110044, Peoples R China. 地址: [ 1 ] Shenyang Agr Univ, Minist Educ, Key Lab Reg Environm & Ecoremediat, Shenyang 110044, Peoples R China [ 2 ] Chinese Acad Sci, Inst Appl Ecol, Shenyang 110016, Peoples R China 電子郵件地址: liyinghua1028@126.com 基金資助致謝: 基金資助機(jī)構(gòu) 授權(quán)號 National Key Technology RD Program 2011BAJ06B02 National Natural Science Foundation of China 50908151 51108275 Program for Liaoning Excellent Talents in University (LNET) LJQ2012101 Program for New Century Excellent Talents in University NCET-11-1012 Science & Technology Program of Liaoning Province 2011229002 Program for Liaoning Excellent Talents in University LR201028 Shenyang University 20210343 20210342 [顯示基金資助信息] 出版商: PARLAR SCIENTIFIC PUBLICATIONS (P S P), ANGERSTR. 12, 85354 FREISING, GERMANY Web of Science 類別: Environmental Sciences 研究方向: Environmental Sciences & Ecology IDS 號: 170DH ISSN: 1018-4619 |
