| Abstract: | Fly ash which was modified by various acids was used in the treatment of phosphorus-containing wastewater.Influence of various factors on the reactions was studied.Experimental results showed that fly ash was good at removing phosphorus from wastewater at pH from 4 to 10.Adding original fly ash 70 g/L and 80 g/L into the solution of containing 100mg/L phosphate after stirring and reaction for 40 min,the effluent can meet Grade II and I under the Integrated Wastewater Discharge Standard of GB9878-1996.Remova... |
