| Abstract: | In this paper,the preparation of polymeric ferric sulfate with sulfate fire dregs was studied.Some factors affecting the production rate of molysite,hydrolyse,polymerization,and the stablility of polymeric ferric sulfate were investigated.Experimental results indicated that liquid polymeric ferric sulfate with brown vicidity and high stability was obtained under the experimental conditions.The density of polymeric ferric sulfate is 1.58 g/mL and the concentraion is 180 g/L.The removal rate of COD Cr approximates to 80% when paper-making waste water is treated with polymeric ferric sulfate. |
| Keywords: | sulfate fire dregs polymeric ferric sulfate coagulant waste water in paper-making |
