为处理高浓度含氮废水,提出生物脱氮组合工艺,首先介绍3种生物脱氮技术原理,同时对其进行比较分析,找出现有技术在实际应用中存在的不足,从而归纳出生物脱氮组合工艺,即“短程硝化+厌氧氨氧化+反硝化”。该组合工艺可去除废水中各种形式的氮,且去除1 mol氨态氮消耗0.75 mol氧气。实际应用中总氮去除率最高可达87.5%,氨氮去除率最高可达91.8%。

In this paper, the principles of 3 kinds of biological denitrification technologies were introduced, compared and analyzed. Defects of the existing technologies in practical application were also found out. After comparison and analysis, an integrated biological denitrification process was proposed by combination of shortcut nitrification, anaerobic ammonium oxidation and denitrification. This combined process could be used to remove various forms of nitrogen in the wastewater and removal of 1 mol of ammoniacal nitrogen would consume 0.75 mol of oxygen. When it was applied to practice, the removal rate of total nitrogen reached to 87.5% and that of ammonia nitrogen reached to 91.8%.
