(Yicai Global) April 11 -- CGN Nuclear Technology Development Co., an affiliate of state-owned nuclear power giant China General Nuclear Power Corp., CGN, today embarked on a highly difficult project for treating printing and dyeing wastewater with textiles firm Victory City International Holdings Ltd. It is China’s first massive commercial application of the electron beam for the treatment of industrial wastewater.
The wastewater treatment system consists of seven electron accelerators and can dispose of 30,000 tons of industrial wastewater per day, said Hu Dongming, general manager of CGN Nuclear Technology Development. It is also the world’s largest single project using the technology and marks a major technological progress in China’s environmental pollution control, state-run China News Service reported today.
Jointly developed by the company and the Beijing-based prestigious Tsinghua University, the technology uses accelerated electron beam to hit or expose the target to identify unconventional physical and chemical changes and to treat refractory organics, antibiotics and pathogenic bacteria in wastewater.
The Jiangmen-based Victory City International is one of the world’s largest knitted fabric manufacturers. It tested the technology with CGN Nuclear Technology Development before its application, said a senior executive of the company, adding that the testing proved that the technology purifies more efficiently than traditional technologies and is expected to address difficulties in treatment of printing and dyeing wastewater.
The Quzhou-based Zhejiang Hengchang Industrial Group Co. is China’s first textile company applying the technology, before Victory City International. CGN Nuclear Technology Development established a demonstrative system for the company last March but the system was only capable of treating 2,000 cubic meters of wastewater per day.
