摘要
本研究采用炭化活化法制备污泥–烟草秸秆基活性炭,在氮气保护气下将污泥与烟草秸秆掺杂制备活性炭,并进行含铜废水的吸附性能研究,继而优化制备污泥–烟草秸秆活性炭过程的最佳制备条件。通过TGA、SEM、FT-IR等分析表征,进一步阐述污泥–烟草秸秆活性炭与废水中Cu2+去除效果的内在关联。利用废弃的固体物料污泥与烟草秸秆掺杂制备碳基吸附材料处理含铜废水,实现了固体废弃物的资源化利用,开辟了城市污水厂污泥资源化利用新途径。
The carbonization activation method was used to preparing activated carbon from sludge-tobacco straw in this study. The activated carbon was prepared by doping the sludge with tobacco straw under N2 protective atmosphere, and the performance of copper-containing wastewater was studied to optimize the best preparation conditions in the preparation of sludge. Tobacco straw activated carbon process. Through the analysis and characterization of TGA, SEM, FT-IR, etc., the intrinsic relationship between the sludge-tobacco straw activated carbon and the removal effect of Cu2+ in the wastewater was further explained. The use of waste solid material sludge and tobacco straw to prepare carbon-based adsorption materials to treat copper-containing wastewater has realized the resource utilization of solid waste and opened a new way for urban sewage plant sludge resource utilization.
