摘要:
由于水体富营养化和温室气体控制的需要,使得具有高效率脱氮,同时N2O逸出最少化的水处理技术的研究开发变得十分迫切.本文报道了采用新型同步硝化反硝化工艺(SND)的研究成果.与传统顺序式硝化反硝化(SQND)技术相比,SND工艺的脱氮与SQND的效率相近,可随溶解氧浓度降低而提高,但N2O逸出量显著降低,且碳氮比的提高可进一步减少N2O的排放.
Abstract:
Control of eutrophication in lake basins claims wastewater treatment techniques with high efficiency for nitrogen removal, and in the same time, it is also needed to reduce N2O emission from the process of nitrification and denitrification for the purpose of controlling the global warming. Therefore, it is of significance to develop practical wastewater processes with high efficiency of nitrogen removal and with low N2O emission as well. In this study, a new process of simultaneous nitrification and denitrification (SND) is investigated and some comparative studies between processes of SND and SQND (sequential nitrification and denitrification) are made. Compared with traditional SQND, SND has a similar efficiency for total nitrogen removal, which can be improved under a lower DO concentration, but the later can reduce N2O emission considerably. Experimental results also indicate that the ratio of TOC to nitrogen has an important influence on N2O emission both from the process of nitrification and from the process of denitrification, and higher value of TOC/N can produce lower N2O emission.
