粉煤灰的改性及其在垃圾渗滤液深度处理中的应用研究
Practical study of modification of fly ash for landfill leachate advanced treatment
摘要
Abstract
The physical and chemical modifications of fly ash were investigated,and used for the landfill leachate advanced treatment.The surface structure and the major crystal phases of fly ash before and after treated were revealed by scanning electron microscope（SEM） and X-ray diffraction（XRD）.Also the adsorption behavior for the landfill leachate advanced treatment on treated fly ash was examined.Results showed that after treated,the surface area and the pore volume of fly ash were increased and adsorption quantity was improved.Through comparison,the best modified fly ash was treated by initiator A which mixed initiator A with initial fly ash at mass ratio of 1∶9,then roasted at 800℃ for two hours.The treated modified fly ash was used for landfill leachate advanced treatment,the adsorption rate of COD and colourity came to 67.3% and 87.3%,respectively.Compare to the initial fly ash which increased 96.0% and 57.8%,respectively.关键词
