曝气生物滤池脱氮的研究进展
Research progress on nitrogen removal by biological aerated filter
摘要
Abstract
The types and principles of nitrogen removal and their practical applications in both industrial and municipal wastewater of BAF are discussed in this paper. The recent research progresses on the influencing factors of nitrogen removal,such as air-water ratio,hydraulic loading,HRT, C/N,backwashing,pH and filter media,are summarized. And the optimum ranges of all those factors are given in terms of the cost and removal efficiency. The main problems including poor carbon source for denitrification and restricted anoxic zone are also presented. And the improved processes to solve those two main problems,such as carbon releasing material,heterotrophic nitrification-aerobic denitrification and integrated process,are discussed. The applications,strengths and problems of these three improved processes are compared. Furthermore,the trend of nitrogen removal by biological aerated filter is also presented.关键词
