Method for preparing high-performance constructed wetland filler by utilizing tailings
The invention discloses a method for preparing a high-performance artificial wetland filler by using tailings, which belongs to the technical field of wetland fillers and comprises the following steps: grinding tailings, preparing sawdust powder, preparing an adhesive aqueous solution, mixing, granulating, drying and roasting. The tailing artificial wetland filler is prepared by taking tailings, wood flour, water, polyvinyl alcohol or sodium carboxymethyl cellulose, aluminum hydroxide and the like as main raw materials through the processes of grinding, mixing, granulating, drying, roasting and the like, and has the characteristics of low preparation cost, high hydraulic conduction coefficient, large specific surface area, relatively uniform pore distribution, high organic matter accumulation speed, high water retention rate, high water retention rate and the like. And the method is suitable for various artificial wetland water treatment processes, and has a good development prospect and practical significance.
本发明公开了一种利用尾矿制备高性能人工湿地填料的制备方法，属于湿地填料技术领域，包括以下步骤：磨碎尾矿、制备木屑粉、配制黏结剂水溶液、混合、造粒、干燥和焙烧，本发明通过以尾矿、木屑粉、水、聚乙烯醇或羧甲基纤维素钠、氢氧化铝等为主要原料，经磨碎、混合、造粒、干燥、焙烧等过程制成尾矿人工湿地填料，具有制备成本低、水力传导系数高、比表面积大、孔隙分布较均匀、有机质积累速度快，对水中磷元素的去除能力较高等优点，适用于各种人工湿地水处理工艺中，具有良好的发展前景和实用意义。
