Sustainability | Free Full-Text | Changes in Microbial and Metabolic Pathways of Solidifying Manganese and Removing Nitrogen from Electrolytic Manganese Residue by the Sulfate-Reducing Bacteria

Mar 15, 2023 | mdpi.com | Guoying Ma |Ying Lv |Xiao Yan |Xingyu Liu

Abstract:Electrolytic manganese residue (EMR) contains a large number of soluble manganese ions and ammonia nitrogen, which seriously endangers the surrounding environment. Solidifying manganese and removing nitrogen has become the primary method for controlling EMR. In this study, an EMR stacking yard in Guangxi was used as a study site to study the solidification of soluble manganese ions and the removal of ammonia nitrogen by mixed bacteria under natural conditions.
