The special project of "Development and Industrialization of Online Monitoring Instrument for Total Nitrogen and Total Phosphorus in Seawater" successfully passed the acceptance

[ Chemical Machinery Equipment Network Industry News ] On March 31, 2022, in the festive atmosphere of the launching ceremony of the institute to commemorate the 60th anniversary of the establishment of the institute, another good news came
.
The special project "Development and Industrialization of Online Monitoring Instrument for Total Nitrogen and Total Phosphorus in Seawater" under the National Key R&D Program "Marine Environment Safety Guarantee" undertaken by the fish satellite researcher of the Spectrum Room of Xi'an Institute of Optics and Mechanics and the research team of Yu Tao's researcher participated in the China 21st Century by the Ministry of Science and Technology.
The online project comprehensive performance evaluation meeting organized by the Agenda Management Center was reviewed and successfully passed the acceptance, which was highly recognized and praised by experts
.
The project is led by the Xi'an Institute of Optics and Mechanics, with the participation of the Institute of Marine Instrumentation of Shandong Academy of Sciences, the First Institute of Oceanography of the Ministry of Natural Resources, and the North Sea Forecast Center of the State Oceanic Administration
.

 

Total nitrogen and total phosphorus in seawater are one of the important indicators reflecting the degree of seawater pollution and eutrophication
.
The online monitoring of total nitrogen and total phosphorus in seawater can provide long-term continuous real-time monitoring data for ecological monitoring and early warning of ecological disasters such as marine red tide and green tide, thereby effectively improving the timeliness and accuracy of forecasting
.
In response to the urgent needs of online monitoring instruments for total nitrogen and total phosphorus in seawater, this project breaks through the integrated design of optical flow, continuous fine spectral detection, dual optical feedback self-calibration, quantitative inversion based on characteristic peak area, and underwater in-situ environmental adaptability design.
and other key technical bottlenecks, successfully developed a total nitrogen and total phosphorus sensor suitable for in-situ online monitoring of seawater, which improved the accuracy, reliability, stability and environmental adaptability of the instrument, and formed a key core technology suitable for marine ecological environment monitoring.
and business application capabilities
.

 

　　Marine ecological environment monitoring technology is one of the relatively weak links in China's marine science and technology field.
In the past few decades, China's marine monitoring instruments have been limited by the technical level, and related equipment for operational applications has basically relied on imports
.
In the major strategic deployment of Xi'an Institute of Optics and Mechanics to build a "marine power", combined with the urgent demand for optical equipment in the field of marine ecological environment monitoring, the research on the expansion of spectral imaging technology in the marine field has been deployed, and the key technology research and development of fine spectral detection has been carried out.
Systematic equipment development work
.
Relying on this project, the in-situ spectral sensor of total nitrogen and total phosphorus in seawater has the characteristics of high technical content, large added value and good comprehensive benefits.
It can be used for marine environmental protection, disaster warning and forecasting, marine ranching, ecological pollution assessment, resource development, etc Providing data reference is one of the important indicators to realize the national marine scientific and technological strength
.
The smooth implementation of this project can provide independent technical means for domestic marine business units to obtain real-time data of total nitrogen and total phosphorus in seawater, enhance China's independent marine monitoring capabilities, and partially solve the bottleneck problem of basic equipment that restricts the construction of China's marine business monitoring network, thereby improving the China's marine ecological environment monitoring level also has important social value and broad application prospects
.

 

　　The research results of the project have also been applied to the Chinese Academy of Sciences' strategic pilot science and technology project (Class A) Beautiful China: Multi-element stereoscopic monitoring technology and application project of water environment and water ecology integration in the main stream of the Yangtze River, as a star-air-ground-water hyperspectral stereoscopic monitoring system An important part of the mid-water in-situ monitoring system, the self-developed online monitoring instrument for total nitrogen and total phosphorus in seawater has been deployed on the water platform of the Poyang Lake Demonstration Area and has achieved operational operation
.
At the same time, the instrument can also provide independent and reliable means for real-time online business monitoring of large-scale surface water systems such as rivers, lakes, and reservoirs, and help the scientific practice of the concept of "lucid waters and lush mountains are the Bank of Jinshan"
.

 

　　At this important historical moment of the 60th anniversary of the establishment of the Institute, the project team will not forget the original intention, keep in mind the entrustment, and live up to the country, vigorously promote the "spirit of scientists", be a new successor of the "Xiguang Spirit", and celebrate the birthday with practical actions.
