Recently, China Guangdong Nuclear Technology Development Co., Ltd. (hereinafter referred to as "China Guangdong Nuclear Technology") and Tsinghua University jointly announced: "China's first, the world's leading" electron beam treatment of industrial wastewater technology has been accredited with scientific and technological achievements, the official completion of China's nuclear energy Industry Association of scientific and technological achievements appraisal. "This means that electron beam treatment of industrial wastewater technology matures, with large-scale industrial application conditions, marking China's advanced treatment of industrial wastewater to achieve a historic major breakthrough in China and the world of industrial wastewater treatment technology, a leap in the field "
Our country's first electron beam processing industrial wastewater technology industrial application breakthrough
"China Guangdong Nuclear Technology Electron Beam Technology Wastewater Treatment Technology Conference and Project Signing Ceremony" was held in Zhejiang a few days ago. Zhang Jianfeng, chairman of CGNPC Technology Co., Ltd., introduced at the conference. CGN Technology has successively conducted electron beam irradiation technology research, wastewater treatment process innovation, Key equipment manufacturing, technical specifications and other related work, and the establishment of the first electron beam processing industrial wastewater demonstration project. At the meeting, CGNIC and Tsinghua University signed a cooperation agreement, announcing that both parties will jointly establish "Joint Research Center for Application of Electron Beam and Environmental Technology" to jointly promote basic research, transformation of scientific and technological achievements and promotion of industrialization of electron beam technology in the field of environmental protection in China Etc. In addition, CGNIC also signed a cooperation agreement with Hengchang Group Co., Ltd. on printing and dyeing wastewater treatment, marking the first time that China's electron beam technology has realized its true industrial application.
Qian Yi, a professor at Tsinghua University and a fellow at the Chinese Academy of Engineering, said that electron beam treatment of industrial wastewater has unique advantages in combination with biological treatment processes and has broad application prospects in the field of environmental pollution control. Especially in the areas of refractory wastewater and industrial wastewater treatment, China will promote the field of industrial wastewater treatment to a higher standard and more environmentally friendly direction.
First technology breakthrough bottleneck
Solve wastewater treatment "global problem"
Chen Dianhua, an expert on scientific and technological achievements appraisal committee, was entrusted by China Nuclear Energy Industry Association to read the appraisal conclusions of the scientific and technological achievements of industrial wastewater treatment by electron beam treatment at the conference. This technical achievement has realized the independent innovation of the electron beam treatment industrial wastewater technology and reached the international advanced level , With broad promotion prospects, will have an important environmental, economic and social benefits.
Accreditation Committee believes that the electron beam treatment of industrial wastewater technology dedicated electronic accelerator water treatment, irradiation reactor overall device and electron beam treatment of industrial wastewater technology, is a domestic initiative, breaking the current bottleneck in the treatment of refractory wastewater bottlenecks, once achieved Large-scale industrialization, can greatly improve China's industrial wastewater treatment level. This technology, combined with biotech's advanced treatment of industrial wastewater processes, offers lower costs and higher levels of purification, enabling high levels of wastewater discharge or reclaimed water. Moreover, the difficult to degrade organic matter with other technology is difficult to compare the advantages, is expected to solve the refractory wastewater treatment "a worldwide problem."
Wang Jianlong, vice president of Institute of Nuclear and New Energy Technology of Tsinghua University, introduced the experimental study proves that the technology is widely used in printing and dyeing, papermaking, chemical, pharmaceutical and other industries wastewater treatment, and water quality complex industrial park wastewater treatment, and can be used for medical Waste, antibiotic bacteria residue and other special hazardous waste harmless treatment. With the technical improvement and comprehensive solution research and development, the future can also be applied to the removal of inorganic heavy metal ions in sewage as well as solid sludge, industrial waste gas, emergency environmental emergencies, medical wastewater, waste treatment and other fields.
"Electron beam treatment of industrial wastewater technology has the characteristics of safety and environmental protection." Wang Jianlong introduction. In terms of safety, although it belongs to the field of nuclear technology applications, but EBT wastewater technology has two characteristics: First, do not use radionuclides, the core device electron accelerator through the power control on and off, no power after the radiation; Second, the electronic accelerator to achieve a safety interlock design to ensure that in the event of any unexpected situation can be timely and rapid power outages, the implementation of protective measures. In addition, industrial wastewater after irradiation by electron beam, and no radioactive, has no effect on the environment.
In terms of environmental protection, electron beam radiation devices have been widely used in industrial production and scientific research all over the world. They have both mature experience for reference and existing laws on protection and operation. Moreover, EBW technology does not generate and emit toxic by-products during the treatment of wastewater, and will not adversely affect the environment and life of the surrounding residents.
Electron beam industrial wastewater treatment technology breakthroughs in industrial applications
At present, electron beam irradiation technology, as an important solution to refractory wastewater, has been listed by the International Atomic Energy Agency (IAEA) as the main research direction for the peaceful use of atomic energy in the 21st century and has become a research hotspot and an important development of new international environmental protection technologies trend. In March 2017, CGNIC completed the first demonstration project of electron beam irradiation treatment of printing and dyeing wastewater in Hengchang Group, Pujiang County, Jinhua City, Zhejiang Province.
