摘要
反硝化滤池是一种将生物氧化与深床过滤机理有机结合的现行污水处理技术。文章阐述了反硝化滤池的工艺原理和工艺特点,从工艺的挂膜与启动、填料、碳源、动力学和反硝化脱氮过程中N_2O的释放方面,详细介绍了反硝化滤池的最新研究进展和探讨了反硝化滤池的发展趋势。同时,指出了反硝化滤池今后在城市污水深度处理中的研究方向。
Denitrification filter is a present type of wastewater treatment technology that combines biological oxidation of microorganism and filtration of the filter media. This review essay elaborates the mechanism and characteristics of denitrification biological filter. The latest research is analyzed from these aspects such as biofilm accretion and start-up, media, carbon source, kinetics and N2O generation during the denitrification, in addition, discussing the trends of the denitrification filter. Simultaneously, the future research directions of denitrification biological filter in urban advanced wastewater treatment are pointed out.
