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.
