Electron Beams for Wastewater Treatment
A joint project of CGN Dasheng and the Institute of Nuclear and New Energy Technology of Tsinghua University has led to successful development of an electron accelerator and an electron beam reactor specifically designed for wastewater treatment. The equipment combines ionizing radiation with conventional technologies for efficient treatment of toxic and hazardous or hard-to-degrade industrial wastewater. The two partners own the intellectual property rights of the core equipment and technologies developed and used in the process. China's first demonstration project using electron beams to treat industrial wastewater went into operation in Jinhua, Zhejiang Province in April 2017. The use of electron beams for treatment of dyeing wastewater proved effective in removing residual pollutants, so that wastewater is treated to an acceptable level or suitable for reuse. China's first 30,000-ton electron beam-based industrial wastewater treatment facility became operational in Jiangmen, Guangdong on June 5, 2020. With seven electron accelerators operating simultaneously, the facility is capable of handling 30,000 tons of wastewater per day, marking a new milestone in the use of domestically developed electron beam technology in wastewater treatment.
China's first demonstration project using electron beam for medical sewage treatment went into operation in Xiyuan Hospital in Shiyan, Hubei Province on November 19, 2020. The electron beams produced are effective in killing pathogenic bacteria and viruses in medical sewage. The facility has a daily capacity of treating as much as 400 tons of medical sewage.
