These components pose a serious threat to the ecological environment. To explore accurate, efficient, and harmless treatment methods for EMR, this study proposes a low-temperature thermochemical approach. The orthogonal experiment design investigates the effects of reaction temperature, reaction time, CaO, Na 2 CO 3 , Na 3 PO 4 , and water consumption on manganese solidified and ammonia removal from EMR. The results indicate that optimal conditions are a reaction temperature of 60℃ and a reaction time of 10 minutes. CaO precipitates Mn 2+ as Mn(OH) 2 , achieving effective manganese solidified and ammonia removal. The addition of Na 2 CO 3 causes Mn 2+ to form MnCO 3 precipitate, while Na 3 PO 4 makes Mn 2+ form Mn 3 (PO 4 ) 2 ·3H 2 O. Increased water consumption enhances the interaction adequacy between ions. Under optimal conditions (CaO 10%, Na 2 CO 3 1%, Na 3 PO 4 0.5%, and 80% water consumption), the removal rate of ammonium ions reaches 98.5%, and the solidification rate of soluble Mn 2+ is 99.9%. The order of influence on ammonium ion removal is CaO > water consumption > Na 3 PO 4 > Na 2 CO 3 . This study provides a novel approach for the efficient and environmentally friendly harmless treatment of EMR.
