AI Technical Summary

Technical Problem

In existing technologies, the treatment of acidic mine water with red mud presents problems such as the easy dissolution of sodium ions leading to increased salinity of the effluent and secondary pollution caused by the high water solubility of sodium humate. Furthermore, the instability of acid-base reactions affects the treatment effect.

Method used

Acid washing is used to pretreat red mud to reduce its reactivity. Inert carriers are incorporated to isolate it from humic acid, control the acid-base reaction rate, and form a stable composite material. Functional components are then added to improve the treatment efficiency.

Benefits of technology

It achieves efficient neutralization, adsorption and stabilization, reduces sodium ion concentration in effluent, improves sedimentation performance, ensures the stability and controllability of the treatment process, and reduces the risk of secondary pollution.

Abstract

本申请涉及废水处理技术领域,具体公开了一种基于赤泥的酸性矿涌水处理剂及其制备方法和使用方法。该处理剂包括以下重量份数的原料:经酸洗预处理的赤泥100份,以及腐殖酸1‑10份、惰性载体5‑20份。本申请通过酸洗预处理降低赤泥的初始反应活性,再通过掺入惰性载体实现对赤泥与腐殖酸两相反应的空间隔离与反应速率调控,不仅保证了处理剂在制备与储存期间的稳定性,更确保了使用时,有效成分能按预期在AMD中逐步、协同地释放,实现高效中和、吸附与稳定化。
