摘要:

高有机氮废水具有有机物浓度高、总氮含量高等特性,经污水厂AO工艺处理后出水仍难以达标排放。对此,改良的AO工艺得到发展。综述了近年来改良AO工艺在优化原水碳源、合理分配碳源及强化反硝化脱氮方面的研究进展,并提出了协调各改良方式,获得高效总氮去除率的方法,以期为AO工艺高效处理高有机氮废水提供参考。

关键词: 高有机氮废水, 多段进水多级AO工艺, 优化碳源, 分配碳源

Abstract:

The high organic nitrogen wastewater has the characteristics of high organic matter concentration and high total nitrogen content. After being treated by AO process in sewage treatment plant, the effluent is still difficult to meet discharge standard. For this reason, the improved AO process has been developed. In this paper, the research progress of the improved AO process in the optimization of raw water carbon source, reasonable allocation of carbon source and enhanced denitrification in recent years is reviewed. And the method of coordinating various improved methods to obtain efficient total nitrogen removal rate is proposed, in order to provide reference for the AO process to efficiently treat high organic nitrogen wastewater.

Key words: high organic nitrogen wastewater, multi-stage AO process with multi-stage inlet water, optimizing carbon sources, distribution of carbon source
