Fe2+-Al3+紫外催化臭氧法降解腈纶废水研究
Degradation of Acrylic Fiber Wastewater with Fe2+-Al3+and Ultraviolet Catalyzed Ozonation Processes
摘要
Abstract
Acrylic fiber wastewater was treated by heterogeneous catalytic ozone process combined with Fe2+-Al3+ and UV. Affecting factors of oxidation capacity were discussed in detail and organic transition was inspected by FTIR and pH transition study before and after the catalytic ozone process. The result shows that Fe2+-Al3+and UV catalyzation have the best oxidation efficiency with COD removal rate up to 77.4%. The content of ammonia nitrogen decreases slowly and the removal rate is only 8.87%. Large amounts of microbial acceptable organic molecules were generated when organic removal rate was 60% along with the BOD/COD rate of 0.277. The acrylic fiber wastewater after the treatments has low pH and organic acids are formed from the oxidation of organic compounds. Moreover, fewer inert groups exist that can influence biological degradability.关键词
