Fighting for the battle of "lake revolution" water environment monitoring business goes online

[ Focus on Chemical Machinery and Equipment Network ] In order to fight for the "lake revolution", the Yunnan Provincial Water Resources Department focused on the protection and governance requirements of the nine plateau lakes, and through the Yunnan "smart water conservancy" big data construction project, the nine plateau lakes were equipped with 200" "Electronic Lake Leader"
.

 

According to reports, the "Electronic Lake Leader" relies on the Internet of Things, artificial intelligence, big data, cloud computing and other technologies, using infrared + LED supplementary light, 4G + dedicated lines and other methods to connect the key water inlets and outlets of the lakes, hydrological monitoring stations, and crowded areas of human activities.
All-weather real-time monitoring of key lake areas
.

 

At present, 200 video surveillance points on the nine plateau lakes have been fully completed, and they have been successfully connected to the Yunnan Province water conservancy big data platform and multiple business systems, realizing the sharing of video surveillance data with various river and lake management units
.

 

It is understood that the back-end of the platform is integrated into the big water data platform of Yunnan Province in a heterogeneous manner.
Big data, intelligent image recognition, and AI artificial intelligence technology will be used to analyze, process and horizontally compare the video data of each lake to build an all-weather information collection automation.
, Transmission network, analysis and intelligent video surveillance system, to further improve the efficiency of river and lake supervision and management and protection level, and realize the intelligent management of rivers and lakes
.

 

　　Years of governance have made Taihu Lake's water quality continue to improve.
However, affected by factors such as lake capture, industrial invasion, man-made water blocking, cruel fishing, and rural pollution, the eutrophication of lakes in many parts of our country is still in a difficult situation.
In addition, facing a severe situation
.

 

　　Looking at the eutrophication of water bodies from the outbreak of cyanobacteria, the eutrophication of lakes is a phenomenon of water pollution caused by the excessive content of nutrients such as nitrogen and phosphorus
.
The development process of eutrophication will be accompanied by the abnormal rapid reproduction of algae and other plankton, which is the water bloom phenomenon that people usually see
.
Eutrophication will affect the water quality, reduce the transparency of the water, make it difficult for sunlight to penetrate the water layer, thereby affecting the photosynthesis of plants in the water, and may cause the supersaturation of dissolved oxygen
.
At the same time, due to the eutrophication of the water body, a large number of algae, mainly blue algae and green algae, grow on the surface of the water body, forming a layer of "green scum", which causes the organic matter accumulated at the bottom to decompose under anaerobic conditions to produce harmful gases and some plankton Biological toxins produced
.

 

　　Real-time dynamic monitoring of lake eutrophication levels can not only understand the pollution status of lakes and other water bodies in time, but also provide the necessary basis for preventing and controlling the occurrence and development of lake eutrophication
.
Traditionally, the monitoring of the eutrophication status of water bodies is generally carried out by means of fixed-point water quality monitoring stations and on-site measurement with water samples collected and brought back to the laboratory for analysis.
This monitoring method can more accurately determine the water quality at the measured location at the time.
, But it is impossible to obtain the macro conditions of the entire water area synchronously, and it takes a lot of manpower and material resources
.

 

　　Satellite remote sensing technology, as a large-scale and high-efficiency earth observation method, can carry out a large-scale normal monitoring of the water environment in the study area, and has a powerful advantage in water environment quality monitoring
.
Through satellite remote sensing technology, the radiation value of the water body in a specific band is analyzed and its spectral characteristics are obtained, and then the corresponding water quality parameter inversion algorithm is established to monitor various water quality parameters
.

 

　　The water environment monitoring business is based on normalized monitoring services, providing environmental protection and water conservancy authorities at all levels with a wide range of high-frequency water quality monitoring base maps, assisting the above departments to fully understand the fundamentals of water quality in the area under their jurisdiction, and timely determine the severity of water eutrophication And delineate the scope
.
Cooperate with other monitoring methods such as automated monitoring stations to form a point-to-face global water quality monitoring system
.

 

　　summary
 

　　Eutrophication of water bodies is a complex ecological phenomenon.
It is not an overnight issue to improve the overall water quality environment
.
Therefore, a reliable, sensitive and rapid early warning system should be established to realize scientific prediction, forecasting, and early warning, and provide intelligent information support for the conservation and protection, optimal allocation, efficient use and decision-making of water ecological protection of water resources in the river basin
