Marine plastic porters, small river pollution is underestimated, monitoring and detection are more important
The three major problems facing human beings 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”. Economic development, environmental protection, and sustainable development are topics that all countries in the world need to face and study seriously. Tons of plastic waste flow into the ocean every day. As of 2020, there will be about 5.25 trillion pieces of plastic. rubbish, of which 269,000 tons floated on the surface of the ocean. Therefore, marine environmental protection has also been raised to a new height. Recently, a study showed that about 2.7 million tons of plastic flow into the ocean every year, and this garbage comes from 1,656 rivers. The research model estimates that the Philippines“Gong Guo”Larger, the country's 4,840 rivers dump more than 356,000 tons of sewage annually. This is followed by India with 126,513 tons per year, Malaysia with 73,098 tons passing through 1070 rivers and China with 70,707 tons passing through 1309 rivers. So the researchers think the bigger culprits are small rivers in urban areas, rather than larger rivers that flow over long distances. Marine plastic porters, the pollution of small rivers is underestimated, and monitoring and detection are more important. What instruments are there to assist in monitoring? First, the water level monitoring instruments of large, medium and small rivers can be used with bubble water level meters. Bottle, logging-free, maintenance-free, anti-vibration, long life, especially suitable for flowing water, large, medium and small rivers, reservoirs, or industrial wastewater with serious water pollution and strong corrosiveness, etc. Its pollution levels are monitored to prevent its contaminants from entering the ocean. The two are aided by the hydrological monitoring system for small and medium-sized rivers, which are mainly used to monitor the water conservancy operation of rivers and lakes. The system detects digital information such as temperature, humidity, wind speed, wind direction, rainfall, water quality, water flow rate, water volume, video images or pictures through various detectors, and uploads them to the online monitoring and monitoring center through the GPRS channel. Log in to various internal management systems and dispatch automation systems on the intranet to understand the situation of the small river. In addition, with the development of science and technology, drones, big data, artificial intelligence, etc. can play a huge role in monitoring, using drones to conduct garbage inspection and data collection on small rivers, and then use artificial intelligence, big data, etc. Collecting and analyzing can have a comprehensive and accurate understanding and mastery of small river garbage, so as to formulate effective management methods.
