摘要
探讨了辛基酚对活性污泥的抑制效应以及维生素C、维生素E单独和联合作用时对抑制效应的拮抗作用。实验结果表明,辛基酚浓度达到64 mg/L时,对本实验系统的活性污泥的比耗氧速率抑制率可达79.7%。维生素E对辛基酚抑制效应有较好的拮抗作用,而维生素C对辛基酚抑制效应的拮抗作用不明显,且高浓度反而会减弱污泥活性。低浓度维生素C与维生素E联合,对污泥抵抗辛基酚抑制效应起协同作用。
The inhibitory effect of octylphenol on activated sludge and the antagonistic effect of vitamin C , vitamin E and their mixture on inhibitory effect were discussed.The results showed that when octylphenol concentration was 64 mg/L, the inhibition rate on specific oxygen uptake rate （ SOUR） of activated sludge could reach 79.7%.Vitamin E had better antagonistic effect on the inhibitory effect of octylphenol , the antagonistic effect of Vitamin C on the inhibitory effect of octylphenol was not obviously.Low concentration vitamin C combining with vitamin E had a synergistic effect on inhibitory effect of sludge resisting octylphenol.
