Abstract:

4,4′- Diaminodiphenylmethane is an important intermediate in chemical engineering. The wastewater produced are mainly composed of 16%- 18% sodium chloride （NaCl）and small amount of organism. Treated by integrated pressure reducing evaporating process and activated carbon absorbing process， the effluent COD_Cr

Key words: salt wastewater, organic wastewater, activated carbon absorbing process

摘要：

4,4′-二氨基二苯基甲烷是一种重要的化工中间体，其生产所产生的废水主要含有质量分数16%￣18%的NaCl和少量的有机物,通过减压蒸发和活性炭吸附处理后，COD<100 mg/L,有机氮<1.0 mg/L，可以作为电解食盐水的补充用水，其经济效益非常可观。
