- Abstract:
- The combined process of electrochemical reduction, three-stage biochemical treatment and modified Fenton was used to treat the nitrobenzene wastewater. The process flow, main design parameters, and the removal effect of major pollutants are summarized. The engineering operation results show that the process has good treatment effect on nitrobenzene wastewater, low treatment cost, and significant impact resistance. In this project, the average influent COD, SS, nitrobenzene, chroma, pH,NH3-N and TN are 1 159 mg/L, 75 mg/L, 96.6 mg/L, 650 times, 9.4, 26 mg/L, and 960 mg/L, respectively. The average effluent COD, SS, nitrobenzene, chroma, pH, NH3-N and TN are 42 mg/L, 7 mg/L, 0.3 mg/L, 15 times, 6.6, 1 mg/L, and 10 mg/L respectively, which meet the requirements of Integrated Wastewater Discharge Standard for Basin Part 1: Nansi Lake and Dongping Lake Basin (DB 37/3416.1-2018) in Shandong Province.
