| Abstract: | By measuring the respiratory oxygen consumption, a study on the aerobic biodegra-dation kinetics of seven priority pollutants(chlorobenzene,o-,m- and p-dichlorobenzene, 1,2,4-trichlorobenzene,o-chlorophenol and 2,4-dichlorophenol) was conducted using activated sludge acclimated by themselves respectively. The experimental results show that the aerobic biodegradation of tested compounds follows the first-order kinetics and the rank of biodegradation rate constant from great to small is o-chlorophenol, 2,4-dichlorophenol, chlorobenzene, o-, m- and p-dichlorobenzene and 1,2,4-trichlorobenzene. When the temperature is 15-30C the increase of temperature stimulates the biodegradation and the relation between the biodegradation rate constant and temperature is complied with Arrhenius equation. |
