Review of biological nitrogen removal enhancement technologies and processes under low C/N ratio
低C/N比条件下高效生物脱氮策略分析

Considering the shortage of organic materials for biological nitrogen removal from wastewater under low C/N ratios, two methods are proposed in order to achieve high efficiency of biological nitrogen removal:.making full use of the carbon source and reducing the requirement of carbon source. To make full use of carbon sources, modified biological nitrogen removal process are introduced, including the anoxic/oxic step feeding process and the pulsed SBR process. To reduce the carbon source requirement in biol...
