[ Focus on Chemical Machinery and Equipment Network ] The three major problems facing mankind in the 21st century are population, resources, and the environment.
One of the solutions to these problems lies in the ocean.
Therefore, some people call the 21st century "the century of the ocean.
" The economy needs to develop, the environment needs to be protected, and the road to sustainable development is a topic that all countries in the world need to face and study seriously.

Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment

There are tons of plastic garbage flowing into the ocean every day.
As of 2020, there are about 5.
25 trillion pieces of plastic garbage, of which 269,000 tons are floating on the surface of the ocean.
Therefore, marine environmental protection has also been raised to a new level.

Recently, a study showed that about 2.
7 million tons of plastic flows into the ocean every year, and this garbage comes from 1,656 rivers.
The research model estimates that the Philippines has a larger “tribute country”, with 4,840 rivers in the country dumping more than 356,000 tons of sewage each year.
This is followed by India with 126,513 tons per year, Malaysia with 73,098 tons passing through 1,070 rivers, and China with 70,707 tons passing through 1,309 rivers.

Therefore, researchers believe that the larger culprit is small rivers in urban areas, rather than large rivers that flow through long distances.
Marine plastic porters, small river pollution is underestimated, and monitoring and testing are more important.
What instruments are there to help monitoring?

　　First, the bubble type water level gauge can be used to monitor the water level of large, medium and small rivers .
The bubble type water level gauge has high measurement accuracy, no gas cylinder, no logging, no maintenance, anti-vibration, long life, especially suitable for flowing water bodies, large, medium and small rivers , Reservoirs, or severely polluted and corrosive industrial wastewater, where it is inconvenient to build logging or expensive wells, monitor the pollution level and prevent pollutants from flowing into the ocean.

Monitoring instrument

　　The two are assisted by the hydrological monitoring system of small and medium rivers, which is mainly used to monitor the operation of rivers and lakes.
The system detects water temperature, humidity, wind speed, wind direction, rainfall, water quality, water flow rate, water volume, video images or pictures and other digital information through various detectors, and uploads it to the online monitoring center through GPRS channel.
Intranet logs into various internal management systems and dispatch automation systems to understand the situation of small rivers.

　　In addition, with the development of science and technology, drones, big data, artificial intelligence, etc.
can show great effects in monitoring, using drones to conduct garbage inspections and data collection on small rivers, and then through artificial intelligence, big data, etc.
Collecting and analyzing can have a comprehensive and accurate understanding and mastery of garbage in small rivers, so as to formulate effective treatment methods.

　　Finally, the editor would like to say that small rivers are also an important part of large and medium-sized rivers.
They play an important role in the material circulation and energy flow between terrestrial ecosystems and aquatic ecosystems.
They have very important ecological functions, and their monitoring and testing cannot be ignored.
