Experimental Study on Combined Process of EOW and MBR for Treatment of UDMH Wastewater

Article Preview

The combined process of Electrolyzed oxidizing water(EOW)and membrane bioreactor(MBR)was applied to treat the UDMH wastewater, and its treatment efficiency was compared with that by MBR alone.In the combined process, the treatment efficiency of UDMH wastewater is better than MBR alone. When the influent COD and UDMH are 800 to 1000 mg•L-1 and 300 mg•L-1, the effluent COD and UDMH are about 55 mg•L-1 and 0.3 to 1.5 mg•L-1 respectively, close the demand of the Discharge standard of water pollutants for space propellant.In the MBR process alone,the effluent COD and UDMH are about 90 mg•L-1 and 45 mg•L-1 respectively, which worse than the combined process EOW-MBR, especially the effluent UDMH far beyond the demand of the Discharge standard of water pollutants for space propellant.
