摘　　要：中国是世界上最大的电解锰生产和消费国,但电解锰的迅猛发展引发的锰渣环境问题尤为突出。由于电解锰渣是生产金属锰排放的酸浸废渣,渣中含有的污染物种类多、浓度高且具有难分散、活性低等性质,对其处理处置已成为电解锰行业和环保领域的研究难点和热点。本文概述了电解锰渣的理化特性与环境特性,对国内外电解锰渣处理技术、处置技术、氨氮和锰的回收及资源化利用进行了总结,分析了各种处理处置技术优缺点及应用前景。针对电解锰渣资源化产业化应用等现实问题,提出必须深入研究电解锰渣理化特性,重点研发低成本、大吞量、市场需求量高、低风险和高市场认知度的资源化技术,展望了电解锰渣作建筑材料资源化的美好应用前景。China has become the global largest producer and consumer of electrolytic manganese metal country. In the rapid development of electrolytic manganese industry,a large quantity of electrolytic manganese solid waste （EMSW） causes serious environmental problems.Due to EMSW is a sort of acid leading residue genera-ted from electrolytic metal manganese production,lots of pollutants with high concentrations,difficulty in dis-persion and low activity,the disposal of EMSW becomes the intricacy and central issue.The physic-chemical and environmental characteristics of EMSW are introduced.The current disposal,recovery of NH3-N and man-ganese from EMSW,and resource technology are summarized.The disadvantage and advantage of the technolo-gy prospect are discussed and forecasted.Aiming to practical recycling of EMSW,it is prerequisite to develop and conduct the resource technology with low cost,high consumption,large market demands,low risk and high market awareness.Finally,the resource technology of utilizing EMR to make construction materials may have good application prospect.
