工业污水处理厂生物脱氮效率提升策略研究

Study on Improving Strategy of Biological Nitrogen Removal Efficiency in Industrial Sewage Treatment Plant

当前,城镇污水处理厂所采用的生物脱氮工艺按照运行性能、构筑物组成以及运行操作形式可以分成固着型生物膜法以及悬浮型活性污泥法。为了探究污水处理厂生物脱氮效率,选择更加合适的生物脱氮方法,对三种不同的生物脱氮方法进行了对比,为污水处理厂脱氮工作的实施提供一定的理论参考。

At present, the biological nitrogen removal process used in urban sewage treatment plant can be divided into fixed biofilm method and suspended activated sludge process according to its operation performance, structure composition and operation form. In order to explore the biological nitrogen removal efficiency of sewage treatment plant and select a more suitable biological nitrogen removal method, three different biological nitrogen removal methods were compared, which provided some theoretical reference for the implementation of nitrogen removal in sewage treatment plant.
