摘要
采用电化学-化学复合氧化工艺处理丙烯腈污水,并对各处理单元的出水水质进行分析。研究发现,丙烯腈污水中酰胺类和羧基类物质的降解效率与TOC、COD等污染物指标线性关系较好,采用官能团滴定分析、紫外可见光谱分析等手段,可以有效表征难降解污染物沿处理流程的迁移转化过程。
The electrochemical and chemical complex oxidation process is used to handle wastewater from acrylonitrile production and the quality of effluent of each treatment unit is analyzed.It is found that the degradation rates of amide and carboxyl compounds in acrylonitrile wastewater show a good linear relationship with the pollutant indexes such as TOC and COD. By means of UV-Vis spectra and functional groups titration,the migration and conversion of refractory pollutants along the treatment process can be characterized effectively.
