- Abstract:
- Treatment effect of immobilized microorganism technology on nitrobenzene wastewater was comprehensively investigated in a practical treatment process of a sewage treatment plant in Liaoyang City based on actual operating data. After treated by the immobilized microorganism technology, most of the nitrobenzene compounds in wastewater were transformed with the removal efficiency more than 90%, and the average removal efficiencies of COD and BOD5 were 84% and 86%, respectively. COD and BOD5 in the effluent reached the discharge requirements of Liaoning Comprehensive Effluent Standard (DB 21/1627-2008), and nitrobenzene compounds in the effluent reached Integrated Wastewater Discharge Standard (GB 8978-1996). However, the wastewater treatment system removed only a small amount of nitrogen pollutants from the wastewater. In view of the situation that total nitrogen in the effluent was not up to standard, corresponding improvement measures were proposed.
