摘　　要：分别用粉状活性炭、粒状活性炭和粘胶基活性炭纤维处理污水处理厂出水,通过对水中COD、氨氮、浊度、pH值等指标进行对比实验,初步研究结果表明,活性炭纤维的吸附速率最快,达到吸附平衡所用时间最短,对水中COD吸附容量达124.6mg/g,浊度的去除率83%,但对氨氮、pH值无明显吸附效果。Powdered activated carbon,granular activated carbon and viscose-based activated carbon fiber were used for disposal of sewage treatment plant effluent.We analyzed COD,ammonia nitrogen,turbidity,pH and other indicators for comparison.Preliminary results showed that ACF adsorption rate reached equilibrium with the shortest time.Adsorption capacity on COD in the water was 124.6mg/g,turbidity removal efficiency was 83%.But for ammonia nitrogen and pH,it had no obvious effect.
