中文摘要
污水中碳氮元素的去除依然是目前污水处理厂运行的重点和难点问题。厌氧氨氧化菌具有同时转化碳氮元素的特异性代谢能力,为共生菌污泥协同去除污染物提供了崭新方向。但对共生菌代谢网络的认识只处于构思阶段,机理认知也尚未统一。为实现污水中碳氮元素的同步去除,针对厌氧氨氧化菌特异性代谢网络和共生菌协同除碳脱氮的研究十分必要。.本研究首次使用二次纳米粒子质谱探针、掠入射-结构光照明超高分辨率显微成像等技术,分析超微观细胞内外基质和产物的转化,阐明活细胞结构及其代谢功能;率先基于厌氧氨氧化菌和共生菌的特异性协同代谢网络,揭示微生物代谢过程为适应新环境的演变规律;进而揭示基质环境、代谢路径和菌体形态三者的对应关系,掌握控制选择性利用基质和生成特定产物的方法;最后,优化微生物对有机物和氮元素的转化过程,实现厌氧氨氧化工艺中碳氮元素同步稳定去除,最终降低污水处理运行成本。
英文摘要
The removal of carbon and nitrogen in sewage is still the key and difficult problem in the upgrade of sewage treatment plants at present. The anammox bacteria have a specific metabolic ability to transform carbon and nitrogen elements at the same time, which presents a new direction for symbiotic bacteria synchronous coupling for carbon and nitrogen removal in sewage. However, the understanding of the metabolic network of symbiotic bacteria is only in the conception stage, and the understanding of its mechanism has not been unified yet. In order to achieve the coupled removal of carbon and nitrogen in sewage, it is necessary to research the specific metabolic network of anaerobic ammonia-oxidizing bacteria and symbiotic bacteria synchronous coupling for carbon and nitrogen removal by symbiotic bacteria. .This study, for the first time, uses the secondary nanoparticle mass spectrometry probe and the ultra-high-resolution micro-imaging technology with grazing incidence and structural light illumination, etc. to analyze the distribution of the inside and outside substrates and products of the super-microscopic microorganism cells, observe the dynamic changes of the living cells, and determine the corresponding relationships among the substrate environment, metabolic pathway and bacteria morphology. By revealing the specific synergistic metabolic network of anammox bacteria and symbiotic bacteria, we further understand the rules of metabolic process changes of microorganisms in adapting to the environment, and realize the methods of controlling the selective use of substrate and the generation of specific products, to efficiently transform the carbon and nitrogen in sewage. Finally, optimize the ratio of coupling transformation of organic matter and nitrogen by microorganisms to realize the regulation of anammox sewage treatment process, achieve the synchronous removal of carbon and nitrogen, and reduce the operating cost.
