城市污水深度脱色技术研究进展
A review of advanced color removal in municipal wastewater
摘要
Abstract
The colored organic matter (CDOM) in the secondary effluent of wastewater treatment plants(WWTPs) has complicated components,which makes it difficult to remove. This paper reviewed the concepts and components of CDOM in WWTPs effluents and various treatment methods that may be employed in the reduction of CDOM. These processes include flocculation,oxidation process, membrane technology and combined processes. The removal efficiencies and mechanism were summarized,influencing factors,comments and prospective applications of each method were analyzed as well. It was concluded that nanofiltration (removal rate 90%-100%),ozone,photocatalysis oxidation and their combined processes (60%-80%) possess the best removal efficiencies. The removal efficiencies of coagulation,ultrafiltraion and their combined processes (50%) are not as good as that of the above methods,but better than that of microfiltration,chlorine oxidizer and UV radiation. Future research in this field should focus on the source and composition of CDOM,the versatility performance of color as well as disinfection and trace organic matters removal,and the possibility of recolor of effluent.关键词
