摘要
阐述了氨氮富营养化所带来的危害及废水生物脱氮原理的 3个步骤 :脱氨基作用、硝化反应和反硝化反应 ;介绍了A/O法脱氮工艺、批式活性污泥法和生物膜系统等传统生物脱氮工艺及其特点 ;同时 ,着重阐述了国内外近些年所出现的生物脱氮技术新材料、新工艺 ,并分析了各自的特点 ;最后 。
The hazards of eutrophication caused by ammonia and nitrogen , the theory of removal of nitrogen in wastewater by biological methods ,which include three steps: ammonia stripping, nitrification and denitrification , have been interpreted. Several traditional biological nitrogen removal techniques and their characters, such as A/O biological nitrogen removal method, sequencing batch reactor and biological membrane method , have been interpreted. At the same time, new materials and techniques produced recent years at home and abroad have been explained, and their characters have been analyzed. At last, the development trends of biological nitrogen removal techniques in the future have been pointed out.
