Abstract:

Glycolylurea wastewater is treated by flocculation-concentration-oxidation-alkali treating-activated carbon fiber(ACF) adsorption. The adsorption rule and the repeated method of activated carbon fiber have been studied emphatically. The overall removal rate of COD is 95.0%, that of glycolonitrile 97.6% and that of the production glycolylurea 92.0%. The smell and color of wastewater are removed completely. The requirement of the discharge standard of the effluent has been reached.

Key words: glycolylurea, wastewater treatment, activated carbon fiber

摘要：
