Degradation of 2,4,6-trichlorophenol (TCP) with co-immobilizing anaerobic granular sludge and isolated aerobic bacterial species was studied in coupled anaerobic/aerobic integrated reactors. The synergism of aerobes and anaerobes within co-immobilized granule might facilitate degrading the TCP and exchange of anaerobic metabolites 4-CP, which promoted system organic removal efficiency and recovered from organic shock-loads more quickly. The biomass specific activities experiment further confirmed that strict anaerobes be not affected over the course 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 microbes function in the same reactor and thereby integrate the oxidative and reductive catabolism.
在耦合厌氧/好氧一体化反应器中，研究了共固定化厌氧颗粒污泥和分离出的好氧细菌对2,4,6-三氯苯酚（TCP）的降解情况。共固定化颗粒内好氧菌和厌氧菌的协同作用可能有助于TCP的降解以及厌氧代谢产物4-氯苯酚的交换，这提高了系统的有机去除效率，并能更快地从有机冲击负荷中恢复。生物质比活性实验进一步证实，在本实验过程中，严格厌氧菌不受有氧环境的影响，好氧活性在共固定化颗粒外层占主导，而内部则以厌氧活性为特征。因此，共固定化颗粒能够使好氧和厌氧微生物在同一反应器中发挥作用，从而整合氧化和还原分解代谢。
