Acid mine drainage (AMD) presents severe ecological pollution challenges because of its extreme acidity and sulphate and toxic metal contents. The bacterial separation of metals by sulphate reducing bacteria (SRB) and diffusion dialysis (DD) are considered as the most efficient techniques for the treatment/valorisation of AMD owing to their low energy consumption and waste effluents. However, the performance of SRB or DD standalone technologies still face several challenges. The integration strategy of these techniques can lead to an improved treatment/valorisation process, with the AMD components recovered and converted into value-added marketable products. These products can financially reduce the total costs of the AMD treatment. In the current review, both approaches, representing the biotic and abiotic methods, are compared in terms of their mechanisms, challenges and efficiencies. In addition, critical evaluations of the feasibility of both methods along with the potential of their integrated processes are discussed and future strategies proposed.

无能微生物集成渗析技术用于酸性矿山排水增值的技术生产评价
酸性矿山排水（AMD）由于其极高的酸度，硫酸盐和有毒金属含量而面临严峻的生态污染挑战。由于硫酸盐还原菌（SRB）和扩散渗析（DD）的低能耗和废物排放，它们被认为是AMD的最有效的处理/增值技术。但是，SRB或DD独立技术的性能仍然面临一些挑战。这些技术的整合策略可以改善处理/评估过程，将AMD组件回收并转化为增值的可销售产品。这些产品可以从经济上减少AMD治疗的总成本。在当前的评论中，代表生物和非生物方法的两种方法，根据它们的机制，挑战和效率进行比较。此外，讨论了对这两种方法的可行性以及其整合过程的潜力进行的重要评估，并提出了未来的策略。
