Exploration of fluorine and chlorine removal methods in the new zinc smelting industry
Thread Content
This year, the prices of non-ferrous metals have risen, and the use of blast furnace ash in the zinc smelting industry has become increasingly important. However, this material contains large amounts of fluorine and chlorine; finding an economical and environmentally friendly way to utilize it represents a significant opportunity in the near future. Traditional resins used for removing fluorine and chlorine generate large amounts of wastewater, posing environmental challenges. In light of these production realities, our project has made breakthrough progress in developing a new type of material for removing fluorine and chlorine. Based on current findings, this material offers the following advantages: 1. Environmental friendliness – the amount of wastewater generated is only about 10% that of traditional resins, significantly reducing environmental costs. Moreover, traditional resins are considered hazardous waste, and figuring out how to dispose of them is also a problem. 2. Cost efficiency – the cost can be reduced to around 50% of the traditional method’s cost, without the need for major changes to the production process. 3. High removal efficiency – levels of chlorine and fluoride can be reduced to below 300 and 50 respectively. 4. The end product is a sodium chloride solution, allowing for zero-emission treatment. What do my colleagues think of this project? Is it promising? Everyone is welcome to join the discussion; you can get in touch with me or leave a comment here
A review article by the research group led by Li Jiaxing from the Institute of Plasma Physics, Hefei Institute of Physical Science, Chinese Academy of Sciences, on the application of plasma-treated materials in water pollution treatment was published in the journal Plasma Applications, Plasma Processes and Polymers (Plasma Process Polym., 4 APR. 2017, online). This article provides a systematic overview of the use of plasma methods to modify material surfaces. It covers an introduction to plasma technology, its applications in modifying materials, research findings on its use in water pollution treatment, and offers prospects for further applications of plasma technology in material modification.
China’s First Pilot Project for Treating Industrial Wastewater Using Electron Beam Irradiation Commences Operation 2017-3-15 20:53:32 Source: Xinhua News Agency Author: Wang Pan Xinhua News Agency, Shenzhen, March 15 (Reporter Wang Pan) China General Nuclear Group, headquartered in Shenzhen, announced on the 15th that China’s first pilot project for treating industrial-scale printing and dyeing wastewater using electron beam irradiation has officially begun operation in Jinhua, Zhejiang. This marks a new phase in the application of electron accelerators in China. Yu Jiang, general manager of the Accelerator Division at CGN Dasheng, explained that in order to better address this global challenge of wastewater treatment, CGN Dasheng has collaborated with the Institute of Nuclear Energy and New Energy Technology at Tsinghua University to undertake projects such as the 863 Program, special initiatives for Sino-Russian international scientific and technological cooperation funded by the Ministry of Science and Technology, and technical assistance projects provided by the International Atomic Energy Agency. As a result, specialized electronic accelerators and irradiation reactors for wastewater treatment have been developed, enabling the effective integration of ionizing radiation technology with conventional wastewater treatment processes for the efficient treatment of toxic, harmful, or difficult-to-degrade industrial wastewater. “Treating wastewater with ionizing radiation requires no addition of extra chemical reagents, and it boasts advantages such as wide applicability, fast reaction speed, and high degradation efficiency; for these reasons, it has been identified by the International Atomic Energy Agency as a key area of research for the peaceful use of atomic energy in the new century. ”According to Yu Jiang, CGN Dasheng has carried out long-term and in-depth research collaborations with Tsinghua University on the use of electron beam irradiation for treating industrial wastewater, resulting in core equipment and treatment processes with complete independent intellectual property rights. At present, CGN Dashing is at the international leading level in terms of ionizing radiation pretreatment technologies and devices for industrial wastewater. Zhang Jianfeng, chairman and general manager of CGN Tech, explained that the textile and dyeing industry generates large volumes of wastewater with complex pollutant compositions, containing many harmful substances that are difficult to biodegrade. The Jinhua demonstration project uses electron beam irradiation technology for the advanced treatment of such wastewater; at present, it can handle 1,500 to 2,000 cubic meters of wastewater per day, enabling the effective removal of residual pollutants and allowing for high-standard discharge of the wastewater or its reuse as recycled water. This technology can also be applied to wastewater treatment in industries such as papermaking, chemicals, and pharmaceuticals, as well as in industrial parks with complex water quality. It can be used for the harmless treatment of certain hazardous substances, such as wastewater containing antibiotics and microbial residues; thus, it holds great prospects for market development.
