Abstract

The invention belongs to the technical field of organic waste treatment, and particularly relates to a method for rapidly converting electrolytic manganese residues from soil by using a microbiological method. Comprising the following steps: (1) mixing bagasse pith powder, sugar refinery filter mud and red mud according to a certain proportion, adding the mixture, electrolytic manganese residues and water into a reaction tank, and fully reacting for 6 hours to obtain corresponding mixed waste residues; (2) mixing and stirring the mixed waste residue, a bio-organic fertilizer and a No.1 compound microbial agent, feeding the mixture into a tank-type fermentation tank for aerobic fermentation, performing rapid fermentation for 144 hours, and turning for 2-3 times during the period, so as to obtain active waste residue with low heavy metal ion content; (3) adding sulfur powder and a No.2 compound microbial agent into the active waste residues, carrying out rapid fermentation for 48 hours, and turning for 2-3 times during the period, so as to obtain regenerated soil; the method fundamentally solves the problems that a large amount of electrolytic manganese residues are piled up for a long time, treatment is difficult, and the treatment cost is high, treats waste with waste, and has great significance on green development of the manganese industry.
