粘胶基活性炭纤维在水深度处理中的应用研究

Study on the Depth Treatment by Viscose-based Activated Carbon Fiber

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,浊度的去除率为83%,但对氨氮、pH值无明显吸附效果。

Powdered activated carbon, granular activated carbon, viscose-based activated carbon fiber were used for disposal of sewage treatment plant effluent .We analysised COD of the water, ammonia, turbidity, pH and other indicators for comparison. Preliminary results show that ACF adsorption rate reached equilibrium in the shortest time. COD of the water adsorption capacity is 124.6 mg/g, turbidity removal rate is 83%. But there is no obvious effect for ammonia, pH adsorption.
