一种二苯硫脲母液回用工艺的研究

Study on a Recycling Process of Diphenylthiourea Mother Liquor

二苯硫脲生产会产生大量的水,废水的COD高,处理难度大。化工行业涉及高COD的废水处理成本较高。介绍一种二苯硫脲的母液回用工艺,该工艺对二苯硫脲母液回用有一定的优势。该工艺的母液适宜比例为50%,回用次数为15次。

Diphenylthiourea production will produce a large amount of water,the COD of wastewater is high,and the treatment is difficult.The chemical industry involves high COD wastewater treatment cost.A mother liquor reuse process of diphenylthiourea is introduced.This process has certain advantages for the reuse of diphenylthiourea mother liquor.The suitable proportion of mother liquor is 50%and the reuse times is 15 times.
