摘要
香料废水作为一种有毒有害的高浓度有机化工废水,COD浓度高达几万mg.L-1,对环境危害极大,其处理工艺成为当今世界各国研究的难点。本文总结了近年来国内外香精香料废水处理技术发展沿革、技术现状与研究进展,着重讨论了物化处理、生化处理特点以及工艺的组合应用,探讨了应用前景。根据我国现阶段情况,高效、低能耗、操作简单、易于管理、多种工艺结合处理香精香料废水是今后的主要发展方向。
Perfume wastewater is a kind of poisonous, harmful and high-strength organic chemical-industry wastewater, The concentration of CODCr is up to 104 mg·L^-1. Its treating technology have been attracting growing attentions all over the world. In this paper, the teclmologieal history, current situation and the main developments of perfume wastewater treatment were summarized, especially on the characteristics of biochemical, physical-chemistry treatlnent and the combination of different processes. Moreover,the key of technology and prospect of application were discussed. According to the reality of China situation, the developing direction for perfume wastewater treatmem technology is poimed.
