摘　　要：随着海水利用的增加,含盐污水的排放量也逐年增加,如何对含盐污水进行有效的处理成为限制海水直接利用的关键因素。试验采用循环流动法把驯化后的耐盐菌固定在活性炭纤维上,研究了生物活性炭纤维对含盐污水处理效果,考察了该工艺对含盐污水中CODcr、氨氮、总磷、浊度的去除率。在系统连续运行下,温度为17～25℃,pH值在7.56～8.12时,系统对CODcr、氨氮、总磷和浊度的平均去除率分别达74.51%、75.59%、38.60%、90.06%。实验结果表明,生物活性炭纤维发挥了活性炭纤维吸附作用和微生物的降解作用,显著提高了含盐污水的净化效果,具有广泛的应用前景。With the increase of seawater utilization,discharge of saline wastewater has been increasing year by year.Effective treatment of saline wastewater become a key element which limits the direct utilization of seawater.Circulating method was used to fix the domesticated salt tolerant micro-organisms to the active carbon fiber.The treatment effect of saline wastewater was investigated using biological activated carbon fiber.The removal efficiency of CODcr,ammonia nitrogen,total phosphorous,turbidity were also studied.When the temperature of saline wastewater was 17～25 ℃,pH was controlled between 7.56～8.12,the average removal rates of CODcr,ammonia nitrogen,TP and turbidity were 74.51%,75.59%,38.60%,90.06%,respectively.Results showed the biological active carbon fiber played both adsorption effect of carbon fiber and degradation function of microorganisms.Biological active carbon had improved pollutant removal efficiency of the saline wastewater signally and had broad prospect of application.
