难生物降解有机废水处理技术现状与发展

工业有机废水都含有毒性和稳定性强的污染物，对于这样的废水难以用常规的物理、化学及生物方法处理。对目前国内外难生物降解有机废水的主要处理技术进行了综述，包括生物处理、化学处理和物理处理及各种联合处理工艺，阐述了各种方法或工艺的优缺点及它们的研究现状及进展。得出了单一工艺对难生物降解有机物废水的处理都存在一定的局限性的结论，指出了新的联合工艺的开发与应用将成为难降解有机废水处理发展的方向。

Development and status guo of treatment technology of organic wastewater containing refractory compounds

There are plenty of toxic and stable contaminations in industrial organic wastewater. It is difficult to remove them by routine biological, chemical and physical processes. This paper reviews treatment technology of organic wastewater containing refractory compounds, such as biological processes, chemical processes, physical processes and their combined treatment processes. Many advantages and disadvantages of these methods and processes are depicted. Development and status guo of the treatment technology research are also stated. The conclusions that the singled processes exist some limitations in dealing with organic wastewater containing refractory compounds is made and that the exploitation and application about new combined processes will become the mainstream is pointed out.
