杨涛, 陈院华, 吕贵芬, et al. Pyrosis-alkali Solution-oxidization-biochemical Process for the Treatment of Isocyanate Wastewater[J]. 2015, (2): 96-99. DOI: 10.16056/j.1005-7676.2015.02.023.
Use pyrosis-alkali solution-oxidization process as previous treatment
and use hydrolysis acidification-BIOFOR as succeed treatment of isocyanate wastewater. The experiment prove that the COD concertration of wastewater can be degraded by 80% after the previous treatment
and can be degraded by 93% after the succeed treatment. The water quality of the final effluent in this system meet the first grade of integrate wastewater discharge standard(GB 8978-1996).
