The "Three-Phase Contact Oxidation A/O Tower" was researched by the company's Professor Jiang Zhenghai, a senior engineer. The team has sincerely cooperated with Zhejiang University and others. After years of hard work, the technology and equipment passed the national scientific and technological achievements appraisal in September 2020. With Academician Hou Li'an as the chairman, famous experts such as the Chinese Academy of Sciences, Tsinghua University, and the Chinese Academy of Environmental Sciences rated it as "internationally advanced level." It has been successfully applied in provincial key projects, urban industrial cluster projects supervised by the Ministry of Ecology and Environment, and rural domestic sewage, dairy industry wastewater treatment and other fields. Recently, the Zhejiang Provincial Department of Economics and Information Technology and the Provincial Department of Finance released the list of technology certification, equipment certification results and reward methods for the first equipment (set) in Zhejiang Province in 2021. The "Three-Phase Contact Oxidation A/O Tower" independently developed by our company was recognized as the "first equipment (set) in China". The "first unit (set)" of major manufacturing equipment is an important means for the high-quality development of manufacturing power and manufacturing launched by the Ministry of Industry and Information Technology. Zhejiang Province's "Key Points for the Development of Equipment Manufacturing Industry in Zhejiang Province in 2022" clearly identifies the "first unit (set)" as the key starting point. It is reported that it is the first product in the Jinhua Development Zone to be recognized as the "domestic first unit (set)" since our province launched the "first unit (set)" certification in 2007. Will receive a reward of 1 million yuan from the provincial finance. At the same time, this first set also puts our company on the list of advanced industrial economic units in Jinhua City in 2021.

Three-phase contact oxidation A/O tower technology and equipment advantages

       The technology and equipment adopt three-phase contact biological oxidation technology of gas, water and mud, which subverts the existing two-phase contact biological oxidation technology of gas/water and water/mud. The technology has gathered a number of domestic and foreign invention patents with independent intellectual property rights of the company. It has been proven in practice that compared with existing technologies, it has the advantages of efficient COD removal, denitrification function, energy saving of 30-60%, land saving of 50-70%, joint treatment of wastewater and waste gas, stable drainage and exhaust gas up to standards, no odor, no secondary pollution, low investment and operating costs, etc. It is especially suitable for sewage treatment engineering construction in rural areas and small towns and zero-increase land improvement projects.Re-research and development, promotion and re-manufacturing

  The company will be guided by the national three-year action plan for environmental protection equipment manufacturing and in accordance with the national dual-carbon and green development strategy, focusing on the research and development of energy-saving and carbon-reducing, zero-carbon and carbon-negative technologies and equipment in the field of environmental protection. It will firmly cooperate with industry, academia and research, and take the "Three-Phase Contact Oxidation A/O Tower" as the "first unit (set) in China" as the key starting point. It will make full use of national, provincial and municipal policies on the promotion and application of the first unit in government procurement, application incentives, application project insurance subsidies, etc. to deepen and expand application areas. Make the company a comprehensive environmental protection enterprise that is both service-oriented and manufacturing-oriented. We would like to thank all sectors of society for their strong support and assistance in the development of our company, and we sincerely request to cooperate with all sectors of society and relevant enterprises to jointly develop the green development of the environmental protection industry.
