- Abstract:
- The combined process of expanded granular sludge bed (EGSB) and aerobic tank was applied to treat the wastewater from chloroacetic acid production, which has the characteristics of high organic matter concentration, high salt content and refractory to biodegradation. The results of commissioning operation showed that the process had steady treatment effect and strong resistance to shock loading, and the effluent COD was lower than 500 mg/L after the commissioning and domestication of the biochemical system. The effluent quality could meet the discharged standard of the downstream sewage treatment plant in the industrial park.
