The instrument helps the "waste removal action" in the Yellow River Basin to hand over the full score answer sheet for water environment management

[ Hot spot attention of chemical machinery and equipment network ] The water environment is an important layer in the ecological environment
.
In the past, due to the rapid development of industry, the importance of water environment was reduced, and the Yangtze River and Yellow River basins had water pollution of varying degrees, which not only affected residents' domestic water use and farmland irrigation, but also had an irreversible negative impact on the ecological environment and human health
.

 

The "14th Five-Year Plan" and the outline of the 2035 long-term goals were released, and the attention of ecological environment construction has been raised to a higher level, and ecological civilization has become a key project of current economic and social development
.
In order to promote the ecological governance of the water environment in an orderly and in-depth manner, in May 2021, the Ministry of Ecology and Environment will carry out the investigation and remediation of solid waste dumping in the Yellow River Basin, aiming to eliminate potential environmental pollution and ensure the ecological environment safety of the Yellow River Basin
.

 

The "waste removal action" in the Yellow River Basin will officially begin in July 2021
.
This waste removal operation has changed the previous manual exploration mode, but is based on drones and satellite remote sensing images, combined with environmental monitoring instruments , to form an "intelligent" water area action mode
.
To put it simply, this mode is to conduct investigations along the watershed, and after obtaining information, experts will carry environmental monitoring instruments to the site for monitoring and remediation
.

 

　　It is understood that in the preliminary investigation, in addition to satellite remote sensing "assistance", UAV remote sensing, verification APP and background information system were also introduced
.
Realize remote sensing technology to improve the accuracy of investigation, and explore new models for remote sensing supervision technology
.
Compared with the previous "waste removal" operation, the "accuracy" of satellite remote sensing has been greatly improved, and the solid waste can be accurately identified, and the accuracy rate has increased from 50% to 70%-80%
.
The remote sensing supervision technology system has changed the mode of relying on manual inspection of solid waste, and promoted the efficiency, informatization and intelligence of solid waste inspection and remediation
.

 

　　In the early stage, the main force was satellites, and in the later stage, environmental monitoring instruments
.
In the later stage of the "waste removal" operation, experts on the one hand based on the existing regional pollution information, on the other hand, needed to use environmental monitoring instruments, such as water quality monitoring river sampling instruments, heavy metals, portable odor detection analyzers, etc.
The pollution situation and solid waste situation in the watershed were investigated again, accurate data was obtained, and a detailed plan was formulated to form a set of precise water environment treatment plans
.

 

　　The Yangtze River and Yellow River basins are relatively wide
.
The use of remote sensing technologies such as satellites and UAVs with environmental detection instruments has greatly improved the efficiency and provided strong support for operations
.
According to the data, in 2021, the "waste removal" operation in the Yellow River Basin will investigate and rectify the banks of the Yellow River mainstream, Huangshui River, and Gansu section of the Wei River in five provinces of Inner Mongolia, Qinghai, Sichuan, Gansu, and Ningxia
.
A total of 39 mixed waste storage sites were cleared, and 41,000 tons were cleaned; 92 domestic waste storage sites were cleaned, and 123,000 tons were cleaned; 115 other solid waste storage sites were cleaned, and 467,000 tons were cleaned; 171 construction waste storage sites were cleaned.
842,000 tons were cleaned up; 42 general industrial solid waste storage sites were collected, and 7.
353 million tons were cleaned up.
In addition, 21,000 tons of hazardous wastes were discovered and cleaned up, effectively preventing ecological and environmental safety risks along the middle and upper reaches of the Yellow River
.

 

　　Not only that, the operation also carried out remote sensing interpretation of about 74,872 square kilometers in the middle and upper reaches of the main stream of the Yellow River.
A total of 662 suspected problem points were found.
In 2022, these suspected problem points will be solved one by one under the investigation and detection of environmental monitoring instruments.

.

 

　　In fact, the Yangtze River Economic Belt has previously carried out "waste removal operations", which also use the satellite + monitoring instrument model
.
Since 2018, the Ministry of Ecology and Environment has organized the "Waste Removal Action" in the Yangtze River Economic Belt for three consecutive years to detect and rectify the dumping of solid waste in the Yangtze River Economic Belt
.
A total of 11 provinces and 129 prefecture-level cities in the Yangtze River Basin Economic Belt have been investigated, with a total area of ​​1.
03 million square kilometers.
9,839 points have been checked and 3,252 problem points have been identified
.
By the end of 2021, 3,221 rectifications have been completed, 56.
761 million tons of various solid wastes have been cleaned up, and the rectification completion rate is 99%
.
Large-scale, full-coverage river environmental improvement has basically eliminated the hidden dangers of environmental safety in the Yangtze River Basin, and effectively and orderly promoted the construction of ecological civilization
.

 

　　Technological convergence brings more possibilities for environmental protection
.
Remote sensing technology + environmental monitoring instrument is not the first attempt of technology integration
.
The operation and application of multiple integrated and intelligent systems such as the digital river monitoring system provide support for improving the ecological compensation mechanism for transboundary rivers, promoting the overall change of water quality in the basin, and building a water ecological civilization
