电解锰渣无害化处理与资源化利用技术研究进展

Review on Decontamination and Resource Utilization of Electrolytic Manganese Residue Technology

电解锰渣属第Ⅱ类一般工业固废。随着电解锰渣产量的增加和国家对环保要求的提高,电解锰渣的合理处置问题受到了越来越多的关注。根据电解锰渣的利用级别,可将电解锰渣的处理方式分为安全堆存、无害化处理和资源化利用三个层次。根据技术特征,可以将电解锰渣处理技术分为安全堆存技术、干法处理技术、火法处理技术及湿法处理技术四大类。本文按照电解锰渣的处理技术特征,对近年来的相关研究进展进行探讨,以期寻找到在技术、经济、市场容量或消纳能力及标准要求等方面同时可行的方案。

Electrolytic manganese slag belongs to the class II general industrial solid waste.With the increase of the output of electrolytic manganese residue and the improvement of environmental requirements,reasonable treatment methods for the electrolytic manganese residue are catching more and more attention.Based on the utilization level of electrolytic manganese slag,the treatment methods of electrolytic manganese slag can be divided into three aspects which are safe storage,harmless treatment and resource utilization,respectively.According to the technical characteristics,the treatment technology of electrolytic manganese slag can be divided into four categories which are safe storage technology,dry treatment technology,fire treatment technology and wet treatment technology,respectively.According to the characteristics of electrolytic manganese slag treatment technology,the paper discussed the related research progress in recent years in order to find feasible solutions in technology,economy,market capacity or absorptive capacity and standard requirements.
