摘要
对活性炭纤维（activated carbonfiber,ACF）进行了热氧化改性处理,并将经过改性处理的ACF用作软填料,考察了其在接触氧化法中对模拟酱油废水的处理效果。实验过程中,对填料表面的生物相进行了镜检分析,并利用扫描电镜（SEM）对挂膜成功后的填料表面进行了观察分析,对酱油废水中CODCr、BOD5、NH3-N、TN、TP的去除效果进行了连续监测分析。结果表明：ACF填料有较好的生物相容性,表面生物相长势良好;在DO2～4mg/L、HRT4～8h的条件下,CODcr、BOD5、NH3-N、TN、TP的平均去除率分别在60%、95%、70%、20%、30%以上。
Activated carbon fiber was modified by heat oxidation and the sauce wastewater treatment effect by modified ACF soft bio-meida in bio-contact oxidation process was researched. During the experiment, microscopic examination was conducted to analyze the microbial morphology on the fiber surface, SEM was used to analyze the meidia surface after bio-film culturing finished and the removal efficicency of CODCr, BOD5, NH3-N, TN, TP from sauce wastewater was continuously monitored and analyzed. The results showed that： ACF bio-media has a preferable biological compatibility, the surface microbial morphology was in a good state and the average removal efficiency of CODCr, BOD5, NH3-N, TN, TP was above 60%, 95%, 70%, 20%, 30% respectively under the condition that the DO was between 2 ～ 4 mg/L and the HRT was between 4 ～ 8 h.
