摘要
近年来,污水脱氮处理技术不断发展,涌现了很多新方法和手段。生物脱氮技术能耗低、易于操作、无二次污染且成本低,是一项极具发展前景的技术。本文介绍了近几年国内外该方向的研究成果,内容包括水中氮污染特征、传统生物脱氮技术与新兴生物脱氮技术,文章阐述了目前生物脱氮技术存在问题,展望了生物脱氮技术的发展趋势。
In recent decades, no matter in theory research or in applications, sewagenitrogen removal treatment technologies has made much progress. A large number of new technologies and new techniques have emerged. Biological denitrification process is less energy consumption and easy to control, no secondary pollution involved, especially, low costs, which makes biological denitrification technology a highly promising technology in water treatment. This article introduced the development process of Biological denitrification treatment in wastewater at home and abroad in recent years. Ineludingwater nitrogen pollution characteristics, the traditional Biological denitrification technology and the new Biological denitrification technology. And this paper also provided a prospect of biological denitrifieation technology trends for future applications in water treatment.
