The water pollution of the Yangtze River is worrying, and monitoring instruments come to help

the Yangtze River originates from the "roof of the world" - the southwest side of the Geladandong peak in the Tanggula mountains of the Qinghai Tibet Plateau. It is the mother river of the Chinese nation and one of the main drinking water sources in China

however, with the rapid growth of China'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 been extended to the center of the river due to water pollution. The total annual sewage discharge in the Yangtze River Basin is more than 25 billion tons, accounting for more than 40% of the country. In recent years, the state has invested a lot in the pollution control of the Yangtze River, but the water pollution situation of the Yangtze River is still serious. 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 on both sides of the river. Drinking water safety is a very severe test for cities along the river. Relevant experts analyzed the water body of the Yangtze River and found that the pollution sources were mainly concentrated in several aspects

the first is the pollution of industrial wastewater and domestic sewage. Industrial and mining enterprise wastewater and urban domestic sewage are one of the main sources of pollution in the Yangtze River Basin. With the development of economy and the increase of water consumption, the amount of waste water and sewage discharged into rivers continues to increase. According to the survey data of the water conservancy department, the current annual discharge of waste water in the Yangtze River Basin has reached 25.6 billion tons, which has more than doubled the amount of waste water and sewage in the 1980s. More than 80% of these waste water are directly discharged into water bodies without runoff treatment, which is the main pollution source of water bodies

followed by agricultural non-point source pollution 2 Put the new broach on the knife box. Agricultural non-point source pollution is another major source of pollution in the Yangtze River Basin, mainly including chemical fertilizer, pesticide pollution, livestock and poultry breeding pollution, agricultural solid waste, rural domestic sewage and runoff pollution in mountain and forest areas. According to the estimation of relevant experts, the total amount of agricultural non-point source pollutants in the Yangtze River Basin and the total amount of pollutants discharged from point sources such as industry and urban life are basically "one third of the world"

there is also a large number of ship pollution caused by the surge in shipping volume. The Yangtze River is the main artery of water transportation across the East and west of China. The shipping industry is very developed. There are more than 210000 ships operating on water all year round. These ships discharge 360million tons of oily wastewater and domestic sewage and 75000 tons of domestic garbage to the Yangtze River every year. In addition, oil and chemical pollution incidents caused by marine accidents also occur from time to time, posing a great threat to the water environment of the Yangtze River

the water environment quality of the Yangtze River is an important factor in the development of the Yangtze River economic belt. It has become an urgent need to carry out the protection of the water environment of the Yangtze River, repair the ecology of the Yangtze River, and speed up the establishment and improvement of a comprehensive monitoring and early warning system in the Yangtze River Basin

with the development of science and technology, technologies such as automatic water quality monitors are also improving. China's attention to the environment that the water price is still higher than that of the trapezoidal screw has driven the market demand for water quality monitoring to continue to expand, and China's water quality monitoring market has also shown an unprecedented high-speed development trend. Last year, under the influence of policy dividends, the subdivision of water quality monitoring industry ushered in a climax of development in stabilizing the association, which was the first voluntary joint development by enterprises. According to incomplete statistics, the market scale of water quality monitoring instruments in China was about 6billion yuan in 2018, and the annual growth rate of the market was more than 10%. Relevant experts predict that by 2020, China's water quality monitoring market capacity is expected to exceed 9.5 billion yuan. In the future, the growth rate of China's water quality monitoring market capacity will be more than 20%, and the application of various professional water quality monitoring instruments and automatic water quality monitoring instruments will be accelerated

the water quality monitoring technology has also developed from the original intermittent monitoring to the current exciting continuous monitoring, and the monitoring means use a variety of technologies such as satellite remote sensing monitoring to achieve efficient and accurate monitoring. Using water quality monitoring instruments to evaluate the water quality results, and timely inform the local government of the status of water environment quality entering the injection molding or molding cladding operation, and timely issue early warning information, which is of great significance to promote the local government to implement water pollution prevention and improve the water environment quality

although China'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 experiencing a critical stage from quantitative expansion to high-quality development. Therefore, under the new development trend of water quality monitoring industry, relevant environmental monitoring enterprises should also continue to strengthen the scientific research and development capacity of water quality monitoring technology and products, and constantly improve the level of industry and equipment. Only by increasing investment in more critical links such as after-sales service, operation and maintenance, and brand differentiation construction, can enterprises continue to grow and occupy more shares in the growing water quality monitoring market

"everyone is responsible for protecting the Yangtze River" is not only a slogan, but also requires the joint efforts of all 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 China's water quality monitoring technology can have more new breakthroughs, and guard China's rivers in an all-round way
