摘要
生物活性炭技术在微污染源水处理中显示了巨大潜力,因此本文开展了相关实验研究。通过挂膜方法制备了生物活性炭,分析了在不同装填高度、过滤速度下的出水指标,并与普通活性炭进行了比较。实验结果表明:生物活性炭在最佳装填高度450mm、最佳滤速6m/h时,对浊度、CODMn和氨氮均有较好的去除效果,明显优于普通活性炭。
Biological activated carbon has shown great potential in the treatment of micro-polluted source water, thus relevant experimental study was carried out in the paper. The pole-shaped biological activated carbon was prepared by biofilm formation method, and then the pollution indices of the effusing water were analyzed with height and flow rate varied. Besides, the ordinary activated carbon was also tested on the effect of purification and taken for comparison.The experimental results show that with the height and flow rate optimized, effective reduction of turbidity, chemistry oxygen demand （COD）,and ammonia ＆.nitrogen content can be achieved by biological activated carbon, which is obviously superior to ordinary activated carbon.
