Chai Liyuan, an academician and professor of the Chinese Academy of Engineering, member of the Standing Committee and Vice President of the Party Committee of Central South University. Research on the theory and technical research of non -ferrous metallurgical environmental engineering and heavy metal pollution prevention. As the first complete person, he won 2 second prizes of national technology invention, 1 second prize of national scientific and technological progress, and 130 national invention patents, and 10 national standards, policies and specifications have been compiled. Development with green.

"We are overcome a group of new 'stubborn diseases' to make them change from 'waste' to resources." On June 14, Central South University Jingui Tower, after 2 months, the reporter once again with the same place with the same location again with the same place with the same location again with the same place with the same place again with the same place with again with the same place. When Chai Liyuan met, he and the team had a new direction and breakthrough.

my country is the largest country in the world's smelting. In the process of smelting, it is unavoidable to produce wastewater, waste gas, and scum of real estate. Chai Liyuan took the lead in establishing a "death team" in heavy metal pollution in the country, not only eliminating pollution such as arsenic and waste acid at the source, but also extracted the price elements in the process of governance.

Today, he aimed at waste salt and urban minerals.

In industrial production, we have to produce tens of millions of tons of industrial waste salt each year. Most companies are either storing them in one place or landfilling underground, which requires high storage and management costs.

Seeing these industrial waste salt, Chai Liyuan germinated a bold idea -recovered and converted it into high -quality sodium sulfide for industrial raw materials.

"No matter how beautiful it is, no action, everything is only 0." In order to achieve a breakthrough from 0 to 1, he led the team to start overcome this problem. At present, this technology has started to test in a company in Guangdong and is about to apply large -scale.

There are nearly 20 billion abandoned electrical electronics products in his vision. Once, they consumed mineral resources buried in more than 80%of the world. Now, among these abandoned items, the recycled steel, non -ferrous metals, precious metals, plastics, rubber, etc. have become "urban minerals", and they are piled around people in the form of "garbage".

Intelligent disassembly and price recovery of these "urban minerals", allow them to return to production in the form of mineral raw materials, become an important material for smelting, and become the key to unlocking the shortage of native resources and environmental pollution. Experiment.

"Hunan builds a technological innovation highland, and the color metal industry is the key! Our team will continue to go deeper, go deep into the front line of the enterprise, understand the needs of enterprises, and do deeper and fine metal pollution prevention." Chai Liyuan said.

He told reporters that not long ago, he and the team raised the purity of arsenic to 99.99999%. Such a high -pure arsenic can be sold to nearly 2 million yuan per ton, and a tonnage product with a purity of 99%can only sell 10,000 Yuan.

Chai Liyuan suggested that Hunan actively strives for a major national scientific and technological infrastructure in Hunan, gathered a group of forward -looking industrial technology innovation talents and R & D teams, and vigorously cultivated advantageous industrial clusters.

He also imagined to introduce more big data technology and equipment, promote standardized technology, build unmanned factories and smart factories, liberate people from dirty, tired, and poorly liberated, and improve production efficiency and product quality.

Speaking of these, his eyes flashed with light, which was relieved and looking forward to it.
