Yu Jiang, general manager of China Guangdong Nuclear Power's Dasheng Accelerators Division, introduced that in order to better solve the worldwide problem of sewage treatment, China Guangdong Nuclear Power Dasheng cooperated with the Institute of Nuclear and New Energy Technology of Tsinghua University to undertake the National 863 Plan, the Ministry of Science and Technology China and Russia International Special tasks such as scientific and technological cooperation projects and IAEA technical assistance projects successfully developed special electron accelerators and irradiation reactors for sewage treatment, effectively combining ionizing radiation technology with conventional wastewater treatment processes to efficiently treat toxic, hazardous or refractory industrial wastewater. Â
"Ionizing radiation treatment of sewage does not require the addition of additional chemical reagents. It has the advantages of wide adaptation, rapid reaction, and high degradation efficiency. It has been listed by the International Atomic Energy Agency as the main research direction for the peaceful use of atomic energy in the century." According to Yu Jiang, China Nuclear Power Corp. Shengli and Tsinghua University have conducted long-term and in-depth research and cooperation in the treatment of industrial wastewater by electron beam irradiation, and formed core equipment and processing technologies with completely independent intellectual property rights. At present, China Guangdong Nuclear Power Co., Ltd. is a world leader in ionizing radiation pretreatment technology and devices for industrial wastewater. Â
According to Zhang Jianfeng, chairman and general manager of CGN Tech, the textile printing and dyeing industry produces a large amount of waste water, contains complex pollutants and contains a large amount of harmful substances that are difficult to biodegrade. Jinhua Demonstration Project uses electron beam irradiation technology to perform advanced treatment of printing and dyeing wastewater. At present, the daily processing capacity is 1,500 to 2,000 cubic meters, which can highly remove the residual pollutants in the wastewater and achieve high-level discharge of wastewater or reuse of water. The technology can also be applied to the wastewater treatment of papermaking, chemical, pharmaceutical and other industries, as well as the wastewater treatment of industrial parks with complex water quality. It can also be used for the harmless treatment of hazardous wastes such as antibiotics wastewater and fungus residue and the development of the market. Broad prospects. Â
China Guangdong Nuclear Power Group, headquartered in Shenzhen, announced on the 15th that the first electron beam irradiation treatment industrial scale printing and dyeing wastewater demonstration project in China was formally launched in Zhejiang Jinhua, as recognized by the IAEA, indicating that China’s electron accelerator application has entered a brand new field.
