Global Network Technology Comprehensive ReportIn the context of global climate change and environmental pollution, how to effectively deal with nitrogen pollution has become an urgent task. In 2023, the No. 1 central document of the Central Committee clearly pointed out that China will accelerate the treatment of black and odorous water bodies in rural areas, and constantly improve the quality of rural ecological environment.

Recently, Zhao Zhirong's team published an international study that delves into the distribution and function of fully ammonia oxidizing bacteria in various ecosystems. This newly discovered microorganism can complete the complete oxidation of ammonia in a biological process, providing new research directions for fields closely related to nitrogen pollution such as agriculture and wastewater treatment.

It is worth noting that the research results of Zhao Zhirong's team have been widely recognized by the international academic community. Multiple papers from around the world have cited their relevant scientific research achievements, covering various ecosystems from the Three Gorges Reservoir Area in China, the soil in New Zealand, to municipal wastewater treatment facilities in the United States.

In the field of practice, Zhao Zhirong's team is at the forefront. They successfully applied the "immobilized microbial denitrification and phosphorus removal technology" to the Shenzhen Maozhou River black and odorous water treatment project. Specifically, the team adopted a multi-level contact oxidation process based on immobilized microbial technology, combined with the use of efficient nitrogen and phosphorus removal functional microorganisms, to achieve water purification treatment in closed water bodies with very low operating costs, successfully achieving the water quality of Maozhou River to meet the surface Class III water standard.
