摘要
利用EOW-MBR组合工艺处理偏二甲肼废水,并与MBR工艺的单独处理效果进行对比。结果表明:EOW-MBR组合工艺对偏二甲肼废水有良好的处理效果,在原水COD_(Cr)为800～1000 mg/L,偏二甲肼为300 mg/L的条件下,组合工艺出水COD_(Cr)为55 mg/L,偏二甲肼为0.3～1.5 mg/L,COD_(Cr)处理结果优于《航天推进剂水污染物排放标准》(GB 14374-93)要求,偏二甲肼处理结果接近GB 14374-93要求。而采用MBR工艺单独处理时,出水COD_(Cr)在90 mg/L左右,偏二甲肼在45 mg/L左右。处理结果与组合工艺相比较差,尤其是偏二甲肼远远超过GB 14374-93排放要求。
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 1 000 mg/L and 300 mg/L.The effluent COD and UDMH are about 55 mg/L and 0.3 to 1.5 mg/L 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 and 45 mg/L 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.
