一种基于缓释修复剂修复重金属污染地下水的方法
By combining acid-modified carbon nanotubes with hydroxyapatite as an external slow-release material and mesoporous SiO2 nanospheres loaded with FeS as an internal slow-release material, a remediation agent column is formed, which solves the problem of treating groundwater with high concentrations of heavy metal pollution and achieves efficient and stable heavy metal removal.

Abstract
本发明公开了一种基于缓释修复剂修复重金属污染地下水的方法，包括以下步骤：S1、外缓释材料制备；S2、内缓释材料制备；S3、投药井设计；S4、投药量计算。本发明以两种不同的缓释材料为基础，相互包覆后形成缓释修复剂，其中，内缓释材料具有更强的吸附能力，可以弥补在高浓度重金属污染地下水条件下外缓释材料效果不好的问题，同时外缓释材料也能够进一步辅助并减缓内缓释材料的释放，最终配合本发明专用的修复剂管柱以及投药量修正公式形成了一套适用于多种复杂重金属污染地下水的长期治理方案，能够对地下水重金属污染起到有效的修复作用。
