Academician Ma Jun: The protection of the Yangtze River should be transferred from end governance to front -end pollution control

Academician of Majun China Academy of Engineering, professor and doctoral supervisor of the School of Environmental College of Harbin Institute of Technology. Entering the research and teaching of water treatment theory and technical research and teaching, create different price -priced iron -manganese oxidants to remove pollution theory systems, develop high manganate and high -speed rail acid pre -oxidation pollution technology, etc. It has an important role. Won the Chinese Young Scientist Award, the "Yangtze River Scholars" Achievement Award (Engineering Science Award), the Royal Society of Chemistry "Sustainable Development Water Award", and the American Chemical Association "Science and Excellent Honorary Award". Won the second prize of the National Technology Invention Award (ranking 1); more than 600 SCI papers, 120 invention patents, 6 US patents, and H factor 105.

The Yangtze River Daily-Yangtze River News (Reporter Liu Yuanhang Lu Yingxue Correspondent Liu Yong) "The Yangtze River Protection should take the Yangtze River Basin as a whole, and coordinate with upstream and downstream cities. Continuous development. "On July 8th, Ma Jun, an academician of the Chinese Academy of Engineering, a professor of the School of Environmental College of Harbin University of Technology, and a doctoral supervisor Ma Jun, said in the" Yangtze River Fair "of the Yangtze River Network.

Do a good job of pollution control at the front end, which can effectively reduce the cost of pollution control

The Yangtze River is an important support for the development of the Yangtze River Economic Belt and an important support for the development of the Chinese nation. Academician Ma Jun introduced: "The urban economy along the Yangtze River coast is large, and it is pivotal in the national development pattern. Overall, the coordinated development of upper and middle and downstream cities. "

Academician Ma Jun believes that to maintain a awe of the ecological environment and reasonably plan the industrial layout of the city along the Yangtze River, "especially the upstream areas need to gradually achieve economic transformation, control the heavy pollution industry, strengthen the construction of the circular economy system, build the green industry system , Gradually realize the steady development of the ecological industry, and provide strategic support for the green development of the entire Yangtze River Economic Belt. "

"To change the economic development mode and achieve green and sustainable development, it is to maximize the optimization of resource allocation, do a good job of pollution control at the source, the front end, and develop the circular economy." The source realizes resource separation and pollution control. For example, oil, solvents, precious metals, etc. are used to separate the source separation and resource utilization through membrane separation and other technologies. The processing sewage after treatment is then used in the chemical park through deep treatment to achieve water resources cycle use. Otherwise, excessive dependence on the treatment of the end, limited environmental capacity will lead to greater human and material resources that are actually invested, which will cause waste of resources.

Building a "non -waste city" requires everyone to participate in garbage classification

"In the process of urban development, the refined classification of garbage is an important way to achieve pollution control, and it is also necessary to build a 'non -waste city'." Academician Ma Jun said.

The "non -waste city" is guided by the new development concept of innovation, coordination, green, openness, and sharing. Through the efforts of the whole people, the green development mode and lifestyle are gradually formed, and the source of solid waste sources is continuously promoted. Reduce the amount of landfill and incineration ratio, and minimize the impact of the environmental development of solid waste to the lowest urban development model.

"For example, urban residents purchase a large amount of fruits and vegetables due to life, and the waste waste and excrement generated after use, and can be made into the farmland as much as possible through the source of fertilizer, feed, etc., which forms a good one. Ecological cycle. "Academician Ma Jun said," Whether the garbage classification or ecological environmental protection, it has never been a few people or some industries. Everyone needs attention and everyone is involved. "

The geographical location of Wuhan will be opened, and the green industrial system must be developed

"In a city, there is vitality when there is water, there is opportunities for water, and there is potential if there is water." Academician Ma Jun said that Wuhan depends on the Yangtze River, which is a "city of hundreds of lakes". The water system is developed. Water and flourish, this is very beneficial.

"Wuhan's geographical location is important, and it has the role of inheriting the Yangtze River Basin." Academician Ma Jun said that he hopes that Wuhan can take a new road of green development to form a complete green industrial system to achieve carbon reduction, pollution reduction, expansion expansion Green and growth coordinated, making models in the development of green industries across the country, and played a key role in the national strategy of the Yangtze River.

In addition to the development of the industry, Academician Ma Jun is also very concerned about water for residents. He said that my country attaches great importance to the safety of residents' drinking water, and has systematic planning and strict and unified rules in the purification of water resources. As long as it meets the tap water required by the factory, through the maintenance of good pipeline system maintenance and refined management of the secondary water supply, ordinary people can use it with confidence, and there is no need to purify it.

"Unreasonable purification may also cause secondary pollution, which leads to an increase in nitrite and other content in water, which will harm the human body." Ma Jun said.

Help achieve the "double carbon" goal, college graduates are very promising

"In the context of achieving the" double carbon 'goal, the model of social development is changing, and the trend of ecological industrialization and industrial ecology means unlimited development opportunities. "Ma Jun said that the rise of emerging industries is inseparable from talents. For support, college graduates must consider from the long run, "When you go to the cross intersection, you cannot follow the inertia. You must plan your career from a new perspective and direction." Recalling his own school experience, Ma Jun was also very emotional: "Upper Before college, I wanted to study mathematics and physics, and I wanted me to study medicine at home, but I finally chose Harbin Institute of Technology and the engineering major. It is found that the social demand and stamina are sufficient, especially under the strategy of carbon peaks and carbon neutralization, and have major development potential in the national economic construction. "

Later, he put forward his expectations and suggestions to college students: "Before going to society, it is very important to establish a great ideal and ambition. As long as there is the right goal, you will have the prospect of development for the people."

"Ecological protection, everyone is the main body, the responsible person, the practitioner. I hope everyone can act and protect the river and blue water to east." Ma Jun said.
