Coupled anaerobic/aerobic biodegradation of 2,4,6 trichlorophenol

Abstract： Degradation of 2, 4, 6-trichlorophenol(TCP) with co-immobilizing anaerobic granular sludge and isolated aerobic bacterial specieswas studied in coupled anaerobic/aerobic integrated reactors. The synergism of aerobes and anaerobes within co-immobilized granule mightfacilitate degrading the TCP and exchange of anaerobic metabolites 4-CP, which promoted system organic removal efficiency and recovered fromorganic shock-loads more quickly. The biomass specific activities experiment further confirmed that strict anaerobes be not affected over thecourse of this experiment by the presence of an oxic environment, aerobic activity predominated in the outer co-immobilized granule layers,while the interior was characterized by anaerobic activity. The co-immobilized granule could thus enable both aerobic and anaerobic microbesfunction in the same reactor and thereby integrate the oxidative and reductive catabolism. 作 者： CHEN Yuan-cai    ZHAN Huai-yu    CHEN Zhong-hao    FU Shi-yu    ZHANG Xue-yong   作者單位： CHEN Yuan-cai,ZHAN Huai-yu,CHEN Zhong-hao(State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, Guangzhou 510640, China)
