硫化铜矿酸性废水固体废弃物资源化利用

    Recycling Utilization of Copper Sulfide Mining Solid Waste

    • 摘要: 硫化铜矿固体废弃物作为代表性的大宗固体废弃物,其资源化利用与处置一直是矿山和矿业领域的研究热点。为满足硫化铜矿矿山复垦与生态修复对大量植生基质的需求,通过对酸性废水底泥进行增肥修复,从而替代土壤作为植生基质进行生态修复,实现硫化铜矿酸性废水固体废弃物资源化利用。同时,在矿区植物资源调查的基础上,采用底泥堆土实验与地栽实验验证其可行性并筛选出底泥生态恢复适生植物。研究结果表明:经调理剂增肥修复后的底泥具有理想的植物营养特性,且配置方法简易。研究还筛选出了玉米草、黑麦草、红叶石楠、大叶女贞、刺槐、毛白杨作为底泥生态恢复的适生植物。本研究结果可为同类型矿山固体废弃物资源化利用提供参考。

       

      Abstract: Copper sulfide solid waste as a representative bulk solid waste, its resource utilization and disposal have always been a research hotspot in the field of mining and mining. In order to meet the demand of copper sulfide mine reclamation and ecological restoration for a large number of plant-derived substrates, remediating the bottom sludge of acidic wastewater by increasing fertilizer, thereby replacing the soil as a plant substrate for ecological restoration. Realized the resource utilization of acid wastewater solid waste from copper sulfide mine at the same time, based on the investigation of plant resources in the mining area, the feasibility of the method was verified by the bottom sediment pile soil test and the ground planting test, and the suitable plants for the ecological restoration of the bottom sediment were screened out. The results showed that the sediment with the addition of the conditioner had ideal vegetative characteristics, and the method of disposition was simple. In addition, zeamexicana, ryegrass, photiniafrase, ligustrumlucidum, false acacia and aspen were selected as suitable plants for the ecological restoration of sediment. The results of this study can provide reference to the same type of mining solid waste resource utilization.
