摘要:

综述了不同电子供体的生物反硝化过程应用于工业含硝酸盐废水治理的可能性。异养反硝化是非常高效的生物脱氮技术,但用于对低C/N废水的处理时,需要外加碳源而增加运行成本,且外加碳源可能引起二次污染。自养反硝化工艺以硫、氢等作为电子供体,可有效降低运行成本,将是工业废水脱硝的主要处理方法。不管异养反硝化还是自养反硝化工艺,都需进一步开发新的反应器和优化运行条件来降低运行成本。

Abstract:

The possibility of biological denitrification process with different electron donors applied to the treatment of industrial nitrate-containing wastewater is summarized.Although heterotrophic denitrification is an efficient biological nitrogen removing technology,it is necessary to add carbon sources,which would increase operation costs,and the additional carbon source may cause secondary pollution.Autotrophic denitrification process with sulfur,hydrogen,etc.as electron donors,which can effectively reduce running costs,will be the main treatment method for industrial wastewater denitrification.Either heterotrophic denitrification or autotrophic denitrification process needs to develop new reactors and optimize running conditions in order to reduce the running cost

Key words: nitrate, heterotrophic denitrification, autotrophic denitrification, wastewater treatment
