Current situation and development trends of denitrification effect by ecological floating bed (EFB)

Abstract

Abstract: Ecological floating bed (EFB) technology has been widely applied to ecological bioremediation engineering fields due to its numerous advantages. Firstly,merits and drawbacks of EFB applied to denitrification are pointed out. Then,the newest technologies and mechanisms of denitrification in recent years are reviewed. Lastly,based on the principle with practicability,discussions have been made on the train of thought,mechanism and advantages about using agricultural straw as substrate for the growth of floating bed plants,microbial adsorbing materials and its bio-denitrification carbon sources. Scientific problems which need solving for this train of thought are brought forward. Beneficial reference is provided for the development of ecological floating bed applied to denitrification technology.

Key words: ecological floating bed (EFB), biological denitrification, ecological bioremediation engineering, agricul- tural straw, carbon source for denitrification

摘要： 生态浮床技术因为诸多优点在生态修复工程中被广泛应用，首先指出了生态浮床在脱氮方面的优缺点，然后回顾了近些年来生态浮床脱氮技术发展的最新技术及机理，最后基于实用性原理，探讨了一种以农业秸秆为浮床植物生长基质和微生物吸附材料及其生物反硝化碳源的思路、机理和优点，并提出了该思路需要解决的科学问题。为生态浮床脱氮技术的发展提供了有益参考。
