- Abstract:
- The coking wastewater treatment project, mainly treating mixed wastewater like ammonia steam wastewater and floor cleaning water, etc.， has a capacity of 1 000 m3/d. A combined process of pretreatment, catalyzed internal electrolysis and the core A/O ceramic membrane bioreactor is adopted. The actual operation results show that the removal efficiency of COD, ammonia nitrogen and phenols are 97.25%, 94.64% and 99.98%, respectively. The effluent quality could meet the indirect discharge criteria of Emission Standard of Pollutants for Coking Chemical Industry (GB 16171-2012), while the operation cost is 10.01 yuan/m3.
