| 摘 要： | 以活性污泥比耗氧速率（specific oxygen uptake rate,SOUR）为考察指标，研究了辛基酚（Octylphenol，OP）对活性污泥活性的抑制效应及其主要影响因素.结果表明：辛基酚浓度达到8mg/L时对试验污泥活性存在轻微抑制效应，其抑制效应随辛基酚浓度增大而增大，当辛基酚质量浓度＞64mg/L时逐渐趋于平缓；辛基酚对污泥活性半数抑制质量浓度为38.6mg/L；一定辛基酚质量浓度下，辛基酚抑制效应主要影响因素有污泥浓度及作用时间；在离开辛基酚作用的环境后，受辛基酚抑制的污泥可在适当条件下恢复部分活性.

| Abstract: | The inhibitory effect of octylphenol and related main factors on activated sludge was investigated by measuring the specific oxygen uptake rate of activated sludge.The results were as follows.(1) There was a slight inhibitory effect on activated sludge when octylphenol concentration was 8 mg/L.The effect was strengthened with the increase of the concentration of octylphenol,and the leveling off of this change when octylphenol concentration reached 64 mg/L.(2) The EC50=38.6 mg/L.(3) Sludge concentration and ... |
