[Effects of phenol presence on the biodegradation of 2,4-dichlorophenol in a bioaugmented system].
Special culture for 2,4-Dichlorophenol(2,4-DCP) degradation were supplemented to an activated sludge system and the effects of the presence of phenol at various concentration on the removal of 2,4-DCP were studied. In addition, the changes of the removal rate of 2,4-DCP and phenol under the long existence of phenol was investigated in semicontinuous test. Results show than the presence of phenol at the concentration of 10 mg/L, 50 mg/L, 100 mg/L and 300 mg/L inhibit the biodegradation of 2,4-DCP and the inhibition increased with increasing of phenol concentration. 2, 4-DCP biodegradation rate declined with the run of semi-continuous test, while the biodegradation rate of phenol was much faster than the first run.
