Study on Partial Nitrification and NO_2^--N Accumulation of SBR in the ANAMMOX

部分亚硝化工艺作为匹配厌氧氨氧化的前置反应,确定其影响因素参数对低碳氮比高氨氮废水的脱氮处理具有深远意义。而如何实现氨氧化长期稳定停留在亚硝化阶段,实现亚硝态氮的累积是亟需解决的难题,也成为近年学者的研究热点。笔者就游离氨浓度、温度、p H值、溶解氧浓度与污泥龄等因素进行分析,探索各因素的具体影响参数,为部分亚硝化工艺的实现提供理论支持,寻找最佳亚硝化途径。

Partial nitrification process is used to match the pre-reaction of anaerobic ammonium oxidation, and it is very significant to determine the influencing factors on the denitrification treatment of low carbon-nitrogen ratio and high ammonia nitrogen wastewater. How to achieve the long-term stable retention of ammonia oxidation in the nitrosation stage, to achieve accumulation of nitrite nitrogen is an urgent problem to solve, also becomes a hot research topic in recent years. In this paper, the free ammonia concentration, temperature, p H, dissolved oxygen concentration and sludge age factors were analyzed, the specific impact parameters of various factors were investigated, which could provide theoretical support for realization of partial nitritation process.
