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.

電子束污水處理

中廣核達勝與清華大學(xué)核能與新能源技術(shù)研究院合作，成功研制了污水處理專用電子加速器和輻照反應(yīng)器，將電離輻射技術(shù)與常規(guī)廢水處理工藝有效結(jié)合，以高效處理有毒有害或難降解的工業(yè)廢水，形成了具有完全自主知識產(chǎn)權(quán)的核心裝備和處理工藝。 2017年4月，中國首個電子束輻照處理工業(yè)廢水示范工程在浙江金華啟動運行，采用電子束輻照技術(shù)對印染廢水進行深度處理，能夠高度去除廢水中殘留的污染物，實現(xiàn)了廢水的高標準排放或者中水回收利用。2020年6月5日，中國首個3萬噸級電子束處理工業(yè)廢水項目在廣東江門建成投運，實現(xiàn)了7臺電子加速器聯(lián)機運行，日處理廢水量最大可達3萬噸，標志著中國自主創(chuàng)新的電子束治污技術(shù)邁入大規(guī)模商業(yè)化應(yīng)用階段。2020年11月19日，中國首個電子束輻照處理醫(yī)療污水示范項目在湖北省十堰市西苑醫(yī)院正式投產(chǎn)，能有效滅殺醫(yī)療污水中的致病菌和病毒，日處理污水量可達400噸。
