汚水窒素化合物を除去する伝統的な生物脱窒法は常にエネルギーとコストを大量に消耗する一方、汚泥と温室効果ガスの排出量もかなり大きいであるため、現在の持続可能な開発という理念に反している。伝統的な脱窒や生物脱窒方法と比べると、アナモックスによる新技術は、曝気コストを現在の30%-40%に減少するのができて、汚泥の排出量と全有機炭素の需要量も50%-70%ほど軽減できるため、汚水生物脱窒法の重要な将来像だと考えられる。今年は今までの研究を体系的にまとめて、検討した。多角度から産業応用におけるaの脱窒技術のあり方、応用モデルおよび技術メカニズムを分析、研究した上、総合的な論文一つを発表した。アナモックスに対する三年間の研究を経て、すでにデザインパラメーターを安定に運行させて、およびその顆粒化のメカニズムや、微生物と無機物の共生関係を釈明できた。実際の汚水排出不安定の問題に対して、当該技術は商業化できるか、あるいは大規模に応用できるかについてはまだ検討の余地があるため、今後はより多くの実際の汚水を導入して、パラメーターを改善し、技術設備の改善と顆粒化メカニズムを再検討する必要があると考えられる。

The biological asphyxiation method for the removal of water asphyxiant compounds in the system is often used to reduce the consumption of a large amount of waste, the amount of waste water from the greenhouse results in a large amount of waste water, and now it is possible to use the concept of environmental protection. The systematic biological removal method is better than the traditional biological removal method, and it is exposed that 30%, 40%, 50%, 70%, 50%, 40%, 50%, 40%, 40%, 50%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40%, 40 This year, this year, we will study the system of research. In the multi-angle operation system, there is a list of documents on the basis of the analysis, research and cooperation of the technical personnel and the technical personnel. In the past three years, we have studied the disease, the stability, the stability, the granulation, the microbiology, the symbiosis, the symbiosis, the biochemistry, the biochemistry, the symbiosis, the symbiosis, the biochemistry. There is a problem of instability in the discharge of international water, and when the technology is used to improve the safety and safety of the system, there is a lot of room for the development of large-scale models, and in the future, it is necessary to improve the safety of international water supply, improve the quality of equipment, and improve the quality of equipment.
