Method for constructing and regreening copper tailing pond in arid region
The invention discloses a method for constructing and regreening a copper tailing pond in an arid region, which mainly comprises the construction of the copper tailing pond and the realization of regreening of tailings, the construction of the tailing pond comprises a rainwater collecting pipe, a drainage pipeline, a reservoir, a filter tank and the like, the rainwater collecting pipe can be used for collecting water in a centralized manner, and the reservoir is externally connected to realize water circulation; and more moisture can be provided for the plant root system in real time. In the regreening of the tailings, fermentation products of agricultural and forestry wastes, bentonite, zeolite powder, biochar and a water-retaining agent are used as improvers, so that the water binding capacity of the tailings and the content of elements such as nitrogen, phosphorus and potassium are increased. The method has the advantages of being high in water permeability, good in water-retaining property, good in anti-seepage function and the like, the method is simple, various solid waste is utilized, resource utilization of the solid waste is achieved, cost is saved, rainwater recycling of the arid region can be improved, the water-retaining property and fertility of the alkaline copper tailing sand are enhanced, and a foundation is provided for achieving mine ecological restoration and vegetation restoration.
本发明公开了一种干旱区铜尾矿库构建及复绿的方法，主要包括铜尾矿库的构建与实现尾矿复绿，尾矿库的构建包括雨水收集管、排渗管道、蓄水池、过滤池等，通过雨水收集管可集中收纳水分，外部连接蓄水池以实现水分循环，可实时为植物根系提供更多的水分。尾矿的复绿是将农林废弃物的发酵产物、膨润土、沸石粉、生物炭以及保水剂作为改良剂，以增加尾矿的持水性和氮、磷、钾等元素的含量。本发明具有透水性强、保水性好、防渗功能佳等特点，方法简单，利用多种固体废弃物，使其资源化利用，节约成本，可提高干旱区雨水循环利用、增强碱性铜尾矿砂的持水性和肥力，为实现矿山生态修复和植被修复提供基础。
