摘要: Phosphorus removal from domestic sewage by adsorption combined photocatalytic reduction with raw and modified red mud (RM) was studied in this paper. The results indicated that RM dosage, reaction time, stirring rate, phosphorus concentration, and initial pH of solution (pH(i)) were the main factors to effect on phosphorus removal. It was found that the phosphorus removal efficiency of modified red mud (RM-m) under the photocatalytic test conditions was higher than only by adsorption process, while raw red mud (RM-raw) showed no significant difference under the two conditions. With initial phosphorus concentration 8.26mg/L, reaction time 60min, stirring rate 200r/min, under the adsorption and photocatalytic test conditions, the optimum dosage and pH(i) of both RM-raw and RM-m were 1.8g/L and 4.0, respectively, and the corresponding phosphorus removal of RM-raw and RM-m were 90.18 and 91.70%, respectively. The optimum amount of RM-m under the two conditions were 1.6 and 1.5g/L, respectively, the optimal pH(i) 3.0, correspondingly, the phosphorus removal could reach high up to 94.30 and 99.96%, respectively.
