Key technology research project on air pollution prevention in Wuhai and surrounding areas started

[ China Instrument Network Instrument Research and Development ] In order to further strengthen the support of scientific and technological innovation to fight the battle against pollution, aiming at the major technical bottlenecks and deep precision governance of air pollution in Wuhai and surrounding areas of Inner Mongolia, in 2018, Inner Mongolia Autonomous Region launched a major project of science and technology - “Study and demonstration of key technologies for air pollution prevention and control in Wuhai and surrounding areas”. On December 15th, the special start-up and implementation plan demonstration meeting was held in Wuhai City. Academician Zhang Yuanhang of the Chinese Academy of Engineering and the Center for Eco-Environmental Research of the Chinese Academy of Sciences, China University of Mining and Technology (Beijing), Henan Polytechnic University, Northern Power United Group Corporation, Shenhua Experts from many universities and research institutions in China, such as Wuhai Energy Company and Wuhai Environmental Monitoring Station, attended the meeting and demonstrated the implementation plan.

Wuhai and its surrounding areas are one of the important energy and heavy chemical industry bases in the country. There are seven industrial parks in the four autonomous regions of Inner Mongolia and Ningxia. The industrial structure is heavy, and the characteristics of high consumption and high emissions are obvious. The task of air pollution control is arduous. The party committee and government of the autonomous region attached great importance to the establishment of the leading group for joint prevention and control of air pollution in Wuhai and surrounding areas, and issued the "Opinions on Strengthening the Joint Prevention and Control of Air Pollution in Wuhai and the Anniversary Area". A series of policy documents such as the Implementation Opinions on Good Pollution Prevention and Control. In order to implement the opinions of the party committee government of the autonomous region, the Science and Technology Department of the autonomous region organized a special study to form a report on the causes of air pollution and pollution control measures in Wuhai and surrounding areas, and listed the list of major technical bottlenecks for air pollution prevention and control in Wuhai and surrounding areas. ". On this basis, around the major environmental bottlenecks such as the analysis of atmospheric pollution sources in Wuhai and surrounding areas, the self-ignition treatment of coal gangue, the air pollution control in the coking industry, and the ecological restoration of the waste rock, the Science and Technology Department of the autonomous region has deployed a special project “Air Pollution in Wuhai and Surrounding Areas”. Research and demonstration of major key technologies for prevention and control, and strengthen the protection system for ecological environmental protection capabilities.

The project adopts the scientific research organization model of collaborative innovation of production, education and research. It is led by Inner Mongolia University of Technology and is jointly developed by Inner Mongolia University of Science and Technology, Inner Mongolia Guangna Coal Industry (Group) Co., Ltd. and Inner Mongolia Mengcao Seed Industry Science and Technology Research Institute Co., Ltd. Implementation. On the basis of previous research, the project will focus on breaking through the major technical bottlenecks such as coal-based solid waste preparation and sealing materials to suppress vermiculite spontaneous combustion technology, control high-temperature industrial flue gas unconventional pollutant technology, and coal-based solid waste synergistic utilization ecological restoration. The project forms a complete set of technical systems for the recycling of solid waste resources to control the pollution of key pollution sources, and provides a new model for solid waste recycling, pollution control and ecological restoration for the ecological environment control of the autonomous region.

According to Dr. Sun Junmin from the Inner Mongolia University of Technology, the project leader, the innovation of the project is to combine the utilization of fly ash with air pollution control and meteorite spontaneous combustion, and rely on the transformation of coal itself to solve high temperature industrial smoke pollution. Control problems. The second is to make full use of the strong adsorption characteristics of porous materials, control the formation and discharge of secondary particulate matter from the source, and achieve low-cost and efficient synergistic removal of high-temperature industrial flue gas.

In order to ensure the smooth implementation of the project, the unit hired 7 experts led by Academician Zhang Yuanhang to form a consulting expert group. The expert group conducted on-site inspections of coal coking production enterprises and demonstration bases such as Shishishan. After listening to the introduction of the implementation plan, they agreed that the project's selection direction was accurate, and identified the entry point of technological innovation in air pollution prevention and control in the region; project implementation plan and technology The route is feasible and the target task is specific. On the basis of previous research, technical research and demonstration will be carried out, and the project results will actively lead the demonstration of air pollution prevention and ecological restoration in Wuhai and surrounding areas. At the same time, the expert group also put forward valuable suggestions and opinions on further improving the project's project setting, implementation plan and technical route.

Yun Tao, deputy inspector of the Science and Technology Department of Inner Mongolia Autonomous Region attended the kick-off meeting and delivered a speech. Yuntao requires that the undertaking unit should actively absorb the first-class research and development institutions and first-class experts from the field at home and abroad to participate in the project and give full play to the role of high-end think tanks. It is necessary to rely on the implementation of the project to promote the industrial agglomeration area of ​​the autonomous region to form an innovative development model of “recycling resources to promote air pollution control”, and support the fight against pollution prevention and regional green development. In addition, he also requested the project team to improve, adjust and refine the implementation plan based on the expert opinions, strengthen communication with the expert group, make good use of domestic and foreign platforms, and absorb advanced technology at home and abroad for the prevention and control of air pollution in Wuhai and surrounding areas. .

In the next step, the Science and Technology Department of the Autonomous Region will continue to strengthen the supply of science and technology for prevention and control of atmospheric pollution. First, continue to implement the joint task of joint prevention and control, focus on the battle against pollution prevention, organize the development and demonstration of advanced applicable technologies, and promote in key industries and key areas. The second is to establish a conference and conference mechanism for the city, promote the coordinated deployment of science and technology in the autonomous region and the economic and social development of the city, and accelerate the formation of a strong atmosphere and work synergy to promote green development through innovation.
