Abstract: The pollution control technologies of electrolytic manganese metal (EMM) both at home and abroad were analyzed and evaluated, and the evaluation index system of EMM pollution control technologies in China established. The weights of evaluation indexes were determined, the analytic hierarchy process (AHP) was selected as the evaluation method, and the best available technology (BAT) list for EMM industry pollution control screened out. The results can provide the technical support for the guidance document of Guideline on Best Available Technologies of Pollution Prevention and Control for EMM Industry.
