工业吡啶废水处理技术研究进展

Research Progress of the Treatment Technology of Industrial Pyridine Wastewater

随着经济的快速发展,化工等行业对吡啶需求越来越高,吡啶废水的排放量也不断增加。吡啶具有致癌、致畸、致突变的特性,随着用量的增加,对人体健康和自然环境会造成潜在的危害。详细介绍了国内外吡啶废水的处理技术,包括物理化学法、生物法和高级氧化技术,总结了不同方法对吡啶的降解效果和降解机理,最后对工业吡啶废水的处理技术提出了进一步的展望。

With the rapid development of economy, the demand for pyridine in chemical industry and other industries is getting higher and higher, and the discharge of pyridine wastewater is also increasing. However, pyridine has great harm to human health and natural environment because of its carcinogenic, teratogenic and mutagenic characteristics.In this paper, the common methods for the treatment of industrial pyridine wastewater were introduced, including physical and chemical method, biological method and advanced oxidation technology. The degradation mechanism and effect of different methods for pyridine were summarized. Finally, the further prospect for the treatment technology of industrial pyridine wastewater was put forward.
