The Man with Salt

"This time I came to Beijing to attend the two sessions, this is a bottle of industrial salt samples extracted from wastewater by Zhongtian Nantong Company." During the two sessions this year, the National People's Congress, Zhongtian Iron and Steel Group Party secretary, chairman of the Board, president Dong Caiping in an interview with reporters, the scene showed a special bottle of "green industrial salt", he said that Zhongtian Nantong Company has successfully built the steel industry "the first in one step completed" salt crystallization project, And is striving to become a world-class high-end green Lingang iron and steel industrial park, "to build a more green modern industrial system to help."

Zhongtian Steel responded with action: invested more than 100 billion yuan to build a world-class high-end green Lingang steel industrial park on the shore of the Yellow Sea, deeply integrated circular economy chain and digital intelligence technology, and created a "policy + technology" two-wheel drive sample of traditional industrial transformation.

Dong Caiping, a deputy to the National People's Congress, said: "We have adopted the most advanced technology and equipment in the world today, and achieved the 'three-zero factory' with zero gas release, zero wastewater discharge and zero solid waste delivery." Through the world's top technology, Zhongtian Nantong Company has transformed the "pollution burden" of traditional steel production into high value-added resources.

Environmental protection is the bottom line of enterprise development, Zhongtian Iron and Steel has always been determined to "regardless of the cost, no retreat" to promote green change.

Faced with the challenges of salt concentration exceeding the upper reaches of the Yangtze River twice and complex coastal geology, the technical team conducted 16 times a day of high-intensity water quality monitoring, accumulated more than 1200 times of sampling, and finally locked the standard water source 5 kilometers from the plant. More pioneering to create a "Zhongtian characteristic salt distribution mode" - through the technical system of "one grain of salt, two drops of water, three processes, four chemical operations" (two drops of water: collaborative treatment of canal water and rainwater; Three processes: membrane separation, water salt separation, spray crystallization; The four modernizations: centralized, intelligent, efficient, and forward-looking), overcome the problems of complex salt and low equipment suitability of steel wastewater, and build the first one-step salt crystallization project in China. This technological breakthrough not only greatly reduces the environmental load, but also realizes the closed-loop management of the whole process of industrial wastewater.

​ They have said that with unprecedented enthusiasm and responsibility, with "innovation as the sail and struggle as the paddle", they will inject youthful energy into high-quality development and break the waves toward the magnificent voyage of Chinese modernization.

"The General secretary's entrustment makes us feel a great responsibility and strengthens our confidence in the deep cultivation of green wisdom." Dong Liyuan, vice president of Zhongtian Iron and Steel Group and general manager of Nantong Company, said that Nantong Company is accelerating the layout of "scenery storage" integrated energy projects, researching green technologies such as hydrogen metallurgy and carbon capture, and promoting the cultivation of new quality productivity, "We will respond to the call of the General Secretary with practical actions, continue to deepen the main industry, strengthen industry, continue to promote green and intelligent development," Build core competitiveness!"

From the rebirth of a drop of water to the rise of an industrial park, Zhongtian Iron and Steel is interpreting the green answer sheet of private enterprises in the new era with "the height of policy guidance, the depth of technological breakthroughs, and the strength of youth charge".

As Dong Caiping says: "Environmental protection is not a choice question, but a required answer." Only by integrating ecological benefits into the blood of the industry can we make Chinese manufacturing both strong and green, stable and long-term.
