高浓度有机废水资源化处理中的催化技术

Catalytic technologies for treatment of high concentration organic wastewater for resource recovery

如何高效资源化处理能源和化学品生产过程中产生的高浓度有机废水成为污水处理行业亟待解决的难题之一。此类废水化学成分复杂、化学需氧量(COD)高、难生物降解,且含多种毒害物质,因此在处理过程中会涉及到较为严苛的水热反应环境和所使用固体催化剂的稳定性问题。围绕现有处理方法面临的诸多挑战以及未来废水资源化利用技术的发展趋势进行相关论述和展望。

Efficient treatment of high concentration organic wastewaters from energy and chemicals production for resource recovery becomes a tough task for wastewater treatment industry.Such wastewaters are featured by complicated chemical composition,high COD content,toughness in biodegradation and containing varieties of toxic substances.Their treatment processes are usually encountered by harsh hydrothermal reaction condition and catalyst stability problems.This paper reviews the challenges with existing treatment methods and discusses the future trends in wastewater treatment technologies for resource recovery.
