Deeply promote the scientific and technological innovation of waste water utilization. On October 28, Xu Nanping, a member of the Party Leadership Group and Deputy Minister of the Ministry of Science and Technology, went to the School of Environment of Tsinghua University to investigate the State Key Joint Laboratory of Environmental Simulation and Pollution Control and held a special symposium.
Vice Minister Xu Nanping listened to the general introduction of the laboratory, focusing on research work on water quality monitoring, wastewater regeneration theory, treatment technology, discharge standards and recycling.
Vice Minister Xu Nanping said in the investigation that sewage treatment has always been the focus of technological innovation in pollution control and environmental protection. The 863 Plan, 973 Plan, Science and Technology Support Plan, and National Science and Technology Major Project have all deployed and continued to support this. Large numbers of talents and technology. It is necessary to conscientiously sum up the existing technical foundation and level, understand the stage of various technologies, strengthen the system integration application of mature technologies, and strengthen the key core technologies that are urgently needed.
Vice Minister Xu Nanping listened to the opinions and suggestions of relevant experts at the symposium, emphasizing the need to perfect different technical systems for different types of sewage, such as domestic sewage and industrial wastewater, and carry out pilot demonstrations in cities and parks. Through demonstration, we will further improve the system integration and stable operation capabilities of complete sets of technical equipment, reduce economic costs, and provide technical support and scientific guidance for large-scale promotion and corresponding policy formulation.
Vice Minister Xu Nanping pointed out that it is necessary to strengthen the research on standard setting. It is necessary to consider factors such as environmental capacity, technical level, and governance costs as a whole, and study and formulate interrelated environmental standards, technical standards, and product standards. It is necessary to study the technical process of various types of wastewater reuse, water quality evaluation and other standards, and form a complete technical standard system around the recycling of sewage.
Wu Yuanbin, Director of the Department of Social Development and Technology, Ministry of Science and Technology, Academician of the Chinese Academy of Sciences, Vice President of Tsinghua University Xue Qikun, Academician of the Academy of Engineering, Dean of the School of Environment, Tsinghua University Wait to attend the symposium or accompany the investigation.
Wooden sleepers ,also called Pinus Sylvestris Wooden Tie,Rail Wood Ties,Rail Hardwood Sleepers,Rail Hardwood Ties, has good elasticity, light weight, easy fabrication, and other significant characteristics of insulation performance is good. Fasteners with wood blocking connection simple, laying and maintenance, transportation is convenient, wooden sleeper and have bigger friction coefficient between gravel ballast. Wooden sleeper toughening corrosion, can absorb more than other sleeper train weight and less prone to fracture. But its drawback is that use fixed number of year is shorter, consumption of large amount of wood. Wooden sleeper easy to corrupt, the reason from insect pests, the influence of the environment and climate, and the spike on the wood blocking hole by using long relaxation, wooden sleeper most commonly so only decades of life. To effectively extend the service life, sleepers generally must be used after filling the anti-corrosion. The sleepers, now use are embalmed, to prevent pests and to extend the use fixed number of year.
