Coal gangue backfilling functional material, preparation method and application of coal gangue backfilling functional material in soil heavy metal solidification
The invention belongs to the technical field of recycling of coal gangue, and particularly relates to a coal gangue backfilling functional material, a preparation method and application of the coal gangue backfilling functional material in soil heavy metal solidification. The invention discloses a coal gangue backfill functional material which comprises the following components in parts by weight: 5-15 parts of a backfill raw material and 5-10 parts of a heavy metal curing agent. The backfilling functional material is prepared and applied to backfilling treatment of the coal gangue, the coal gangue can be cured, and leakage of heavy metal ions in the coal gangue is prevented.
本发明属于煤矸石的回收利用技术领域，具体而言，涉及一种煤矸石回填功能材料、制备方法及其在土壤重金属固化中的应用。本发明公开了一种煤矸石回填功能材料，按照重量分数计，包括：回填原料5～15份以及重金属固化剂5～10份。本发明通过制备回填功能材料并将其应用于煤矸石回填处理中，能够对煤矸石进行固化，防止煤矸石中重金属离子的外渗。
