PREPARATION OF ADSORBENT BY COMBINED DRINKING WATER TREATMENT SLUDGE AND POWDERED ACTIVATED CARBON AND ITS AMMONIUM REMOVAL PERFORMANCE

  • 摘要: 将净水污泥与粉末活性炭复合制备吸附剂,用于去除水中的氨氮。研究了净水污泥与粉末活性炭的最佳复合比例及煅烧温度,并采用EDX、SEM、XRD、FTIR、BET对吸附剂进行表征。考察了吸附时间、溶液初始pH、吸附剂投加量、氨氮初始浓度对氨氮吸附效果的影响。结果表明:复合吸附剂的吸附性能优于原泥,当吸附时间为5 h,pH为9时氨氮去除效果最佳。对实验结果进行吸附等温线及吸附动力学模型拟合,发现复合吸附剂对氨氮的吸附过程符合Langmuir等温吸附模型及二级动力学方程。
