Abstract:
The vitamin pharmaceutical wastewater is difficult to degrade, due to great fluctuations in water quality, high organic load, and high concentration. Taking the wastewater treatment process system reconstruction of a large vitamin pharmaceutical enterprise in Hubei Province as an example, the optimization of the EGSB and A2O process operation is introduced. The average sludge particle size in the improved EGSB reactor is 2-2.6 mm and the sludge loss rate of the reactor is reduced to about 10%. The final effluent quality of the system could meet the Discharge Standard of Water Pollutants for Pharmaceutical Industry Chemical Synthesis Products Category (GB 21904-2008), and the treatment cost was 4.81 yuan/m3.
