| Abstract: |
| Material balance and heat balance of stripping distillation deamination system were theoretically calculated, and calculated results were compared with practical operation indexes in engineering case. The results show that actual operation indexes are consistent with theoretical calculation results. Deamination technology by stripping and rectifying can not only remove ammonia and nitrogen of wastewater to less than 10 mg/L, but also recover ammonia with concentration of 15% above. |
