摘要
短程反硝化以其碳源消耗量、废污泥产量、温室气体排量极低及无需曝气等优势,被认为是最具研究潜势的厌氧氨氧化底物供给技术,成为近年来研究热点。本文首先介绍了短程反硝化工艺原理;其次从污泥源、反应时间、碳源类型、碳源量及pH等5个方面总结了影响短程反硝化工艺启动因素;随后综述了短程反硝化耦合厌氧氨氧化工艺的重要研究进展,同时指出了耦合工艺实验研究与工程应用的不足,并提出了解决实验与工程应用缺陷的方案;最后展望了耦合工艺处理城市污水和工业硝酸盐废水的可行性及应用前景,认为全面分析工业硝酸盐废水化学组分与基于分子生物学水平的宏基因组学测序、元转录组学技术是未来耦合工艺同步处理城市污水和工业硝酸盐废水的研究重点。
Partial denitrification is considered to be the most potential anaerobic ammonium oxidation(Anammox)substrate supply technology due to its advantages of comparative low carbon consumption,waste sludge production,greenhouse gas emissions and no aeration,and has become a research hotspot in recent years.Firstly,the principle of partial denitrification process is introduced.Secondly,the start-up factors affecting partial denitrification process are summarized from five aspects:sludge source,reaction time,carbon source type,carbon source quantity and pH.Then,the important research progress of partial denitrification coupled Anammox process is summarized,and the shortcomings of experimental research and engineering application of the coupling process are pointed out,and the solutions to the defects of experimental and engineering application were proposed.Finally,the feasibility and application prospect of the coupling process for the treatment of municipal wastewater and industrial nitrate wastewater are prospected.It's considered that comprehensive analysis of chemical components of industrial nitrate wastewater,metagenomics sequencing and meta transcriptomics technology based on molecular biology level will be the focus of future research on simultaneous treatment of municipal wastewater and industrial nitrate wastewater by coupling process.
