Solid waste resource recycling method
The invention discloses a method for recycling solid waste resources. The method comprises the following steps: crushing, recovering precious metal elements, crushing again, drying and preparing cement. According to the solid waste resource recycling method, gold, silver and other valuable elements are recycled through solid waste resources, the comprehensive utilization rate of the resources is high, and meanwhile heavy metal pollution is small; the solid waste resource recycling method provided by the embodiment of the invention solves the problem of solid waste resource recycling, meets the environmental protection requirement, and realizes comprehensive recycling and harmless treatment of resources; and according to the solid waste resource recycling method disclosed by the embodiment of the invention, the heavy metal is recycled and then is used for preparing the cement, the existing cement aggregate is replaced, the problem of insufficient raw materials of the existing aggregate is solved, the problem that the solid waste resource is difficult to treat is also solved, and the method has a wide application prospect.
本发明公开了一种固废资源回收再利用方法，包括：粉碎、回收贵金属元素、再次粉碎、干燥和制备水泥。本发明实施例的固废资源回收再利用方法利用固废资源回收金、银等有价元素，资源综合利用率高，同时重金属污染小；本发明实施例的固废资源回收再利用方法解决了固废资源再利用的问题，符合环保要求，实现资源综合回收利用和无害化处理；本发明实施例的固废资源回收再利用方法经过重金属回收以后再用于制备水泥，替代了现有水泥骨料，解决了现有骨料原料不足的难题，同时也解决了固废资源难以处理的难题，具有广泛的应用前景。
