摘要

锰作为一种矿物在地壳中含量丰富，通常通过提取和冶炼活动进入采矿和冶金废水中。然而，对毫米波除锰技术的全面研究仍然有限。本文首先介绍了锰的基本性质和危害，然后详细介绍了两种具有代表性的含锰毫米波的形成过程、特征和危害，即酸性矿山水（AMD）和电解金属锰渣渗滤液（EMMRL）。将目前的除锰技术分为化学法、物理化学法和生物法，重点介绍了目前应用较为广泛的化学沉淀法、化学氧化法、吸附法和新兴的电化学法等，并对其典型案例、除锰机理及优缺点进行了分析。并总结了影响这些技术有效性的关键因素。含锰废水的资源回收目前主要通过碳酸盐沉淀法、磷酸盐沉淀法和电化学方法实现。本文还对未来毫米波中锰的脱除和回收进行了展望。

A review of technologies and mechanisms for the removal and recovery of manganese from mining and metallurgical wastewater

Manganese is abundant in the Earth's crust as a mineral and commonly enters mining and metallurgical wastewater (MMW) through extraction and smelting activities. However, comprehensive reviews on manganese removal technologies for MMW remain limited. This paper begins by introducing the basic properties and hazards of manganese and then details the formation processes, characteristics, and hazards of two representative types of manganese-containing MMW, namely, acid mine drainage (AMD) and electrolytic metal manganese residue leachate (EMMRL). This study then categorizes the current manganese removal technologies into chemical, physicochemical, and biological methods, and special attention is given to the widely used techniques, such as chemical precipitation, chemical oxidation, adsorption, and emerging electrochemical methods, along with their typical cases, removal mechanisms, and advantages and disadvantages. The key factors that influence the effectiveness of these technologies are also summarized. Resource recovery from manganese-containing wastewater is currently achieved through carbonate precipitation, phosphate precipitation, and electrochemical methods. This paper also discusses some prospects for the future removal and recovery of manganese from MMW.

期刊介绍： The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
