Yangtze River water pollution is worrying, monitoring instruments come to help

However, with the rapid growth of my country's population and the rapid development of social industry, the water quality of the Yangtze River has been polluted to varying degrees. It is reported that there are more than 500 water intakes on both sides of the Yangtze River, and some of them have extended to the center of the river due to water pollution. The total annual sewage discharge in the Yangtze River Basin reaches more than 25 billion tons, accounting for more than 40% of the country. In recent years, although the state has invested heavily in pollution control in the Yangtze River, the water pollution situation in the Yangtze River is still severe. At present, 60% of the water bodies in the main stream of the Yangtze River have been polluted to varying degrees.

The water quality of the Yangtze River has further deteriorated, seriously threatening the drinking water safety of people along both sides of the river. Drinking water safety is a very severe test for cities along the river. Relevant experts analyzed the water bodies of the Yangtze River and found that the sources of pollution are mainly concentrated in several aspects.

The first is the pollution of industrial wastewater and domestic sewage. Wastewater from industrial and mining enterprises and urban domestic sewage are one of the main sources of pollution in the Yangtze River Basin. With the development of the economy and the increase in water consumption, the amount of wastewater discharged into rivers continues to increase. According to survey data from the water conservancy department, the current annual discharge of wastewater in the Yangtze River Basin reaches 25.6 billion tons, which has exceeded the amount of wastewater discharged in the 1980s. More than 80% of these wastewaters are directly discharged into water bodies without treatment, becoming the main source of water pollution.

Secondly, agricultural non-point source pollution is serious. Agricultural non-point source pollution is another major source of pollution in the Yangtze River Basin, which mainly includes: chemical fertilizer and pesticide pollution, livestock and poultry breeding industry pollution, agricultural solid waste, rural domestic sewage and runoff pollution in mountain and forest areas, etc. According to relevant expert estimates, the current total amount of agricultural non-point source pollutants in the Yangtze River Basin is basically "one-third of the world's total amount of pollutants discharged from point sources such as industry and urban life."

There is also a large amount of ship pollution caused by the surge in shipping volume. The Yangtze River is the main water transportation artery that runs from east to west in my country. The shipping industry is very developed. There are more than 210,000 ships operating on the water all year round. These ships discharge 360 ​​million tons of oily wastewater and domestic sewage into the Yangtze River every year, and discharge 75,000 tons of domestic garbage. . In addition, oil and chemical pollution incidents caused by general casualties also occur from time to time, posing a great threat to the Yangtze River water environment.

The water environment quality of the Yangtze River is an important factor in the development of the Yangtze River Economic Zone. Carrying out Yangtze River water environment protection, restoring the Yangtze River ecology, and accelerating the establishment and improvement of the Yangtze River Basin comprehensive monitoring and early warning system have become important factors in promoting the Yangtze River water body. urgent need for protection.

With the development of science and technology, technologies such as online automatic water quality monitors are also constantly improving. my country's emphasis on water environment has driven the market demand for water quality monitoring instruments to continuously expand, and my country's water quality monitoring market has also shown a rapid development trend. Last year, under the influence of policy dividends, the water quality monitoring industry segment ushered in a climax of steady development. According to incomplete statistics, the market size of my country's water quality monitoring instruments in 2018 was about 6 billion yuan, and the market growth rate for the whole year was more than 10%. Relevant experts predict that by 2020, my country's water quality monitoring market capacity is expected to exceed 9.5 billion yuan. In the future, the growth rate of my country's water quality monitoring market capacity will be more than 20%. The application of various professional water quality monitoring instruments and automated water quality monitoring instruments will be promoted at an accelerated pace.

Water quality monitoring technology has also developed from the original intermittent monitoring to the current continuous monitoring. The monitoring method uses a variety of technologies such as satellite remote sensing monitoring to achieve accurate monitoring. Using water quality monitoring instruments to evaluate water quality results, promptly reporting water environment quality status to local governments, and issuing timely warning information are of great significance to promoting local governments to implement water pollution prevention and control responsibilities and improve water environment quality.

Although my country’s water quality monitoring equipment industry is developing rapidly, it still faces many challenges. In general, the current development of water quality monitoring equipment is going through a critical stage from quantity expansion to high-quality development. Therefore, as the water quality monitoring industry continues to present new development trends, relevant environmental monitoring companies should also continue to strengthen the scientific research and development capabilities of water quality monitoring technologies and products, and continuously improve industrial and equipment levels. Only by increasing investment in more critical links such as after-sales service, operation and maintenance, and brand differentiation construction can it be conducive to the sustainable growth of the company and occupy more shares in the ever-growing water quality monitoring market.

　"Protecting the Yangtze River is everyone's responsibility" is not just a slogan, green waters and lush mountains require the joint efforts of each of us. Enterprises reduce pollution emissions, actively classify personal garbage, and monitor the water quality of the Yangtze River in real time. We also hope that my country's water quality monitoring technology will have more new breakthroughs to protect our country's great rivers!
