氨肟化法己内酰胺生产废水处理技术研究及应用现状
|
摘要
氨肟化法己内酰胺生产废水成分复杂,处理难度较大,已成为我国己内酰胺生产领域的研究热点。综述了氨肟化法己内酰胺生产废水的预处理技术、生化处理技术和深度处理技术,以及各类组合处理技术的研究和应用现状,指出己内酰胺生产废水处理工程化技术的开发,不仅要考虑到工艺技术的有效性,也要考虑到运行成本等因素,设计出抗冲击能力强、运行效率高、处理成本低、自动化程度高的己内酰胺生产废水处理系统是今后的发展方向。
Industrial wastewater of caprolactam produced by ammoximation method has complicated components, which is hard to be treated; therefore, its treatment has become a hotpot of domestic caprolactam production field. The processes of the said kind of wastewater pretreatment, biochemical treatment and advanced treatment were elaborated; besides, the research and application status of different kinds of combination processes were also introduced. It was pointed out that, developing engineering techniques for treatment of industrial wastewater of caprolactam produced by ammoximation method should consider not only technical effectiveness,but also operation cost and some other factors. To develop a caprolactam production wastewater treatment system with characteristics of strong anti-shock loading capability, high operation efficiency, low cost and high automation degree, was the direction of the future research.
