Lithium-ion Battery Manufacturing Wastewater Treatment
Boromond team presents a typical case study over uses of boron doped diamond electrode in lithium-ion battery manufacturing wastewater treatment process project in this article.
Guangxi Pengyue Ecological Technology Co., Ltd.(Guangxi Pengyue), a subsidiary of the publicly listed Chanhen Chemical Corporation (002895 SHE), stands at the forefront of innovation in the phosphate industry and production of iron phosphate,one of the major lithium-ion battery cathode materials for electric vehicle batteries to meet the rising demand for electric vehicles.
This visionary approach serves as a pivotal solution for two major industries – copper electrolysis and the phosphorus chemical sector. Its overarching goal is nothing less than sustainable development for both industries. The production methodology for phosphoric acid forms the cornerstone of this project, following the hemi-dihydrate wet process. From this base, the process is further refined to yield high-purity phosphoric acid, calcium dihydrogen phosphate, ferric phosphate, and other valuable by-products. These products are crucial in various applications, contributing significantly to the economic viability of the project.
This innovative method provides a critical fix for two important industries: the chemical phosphorus sector and copper electrolysis. Nothing less than sustainable development for both industries is its main objective. The hemi-dihydrate wet process is the foundation of this project’s phosphoric acid production approach. High-purity phosphoric acid, calcium dihydrogen phosphate, ferric phosphate, and other important byproducts are produced by refining the process further from this base. These goods are essential for a number of applications and greatly increase the project’s financial sustainability.
However, no endeavor of this magnitude is without its fair share of challenges. One prominent challenge faced by this project is the presence of wastewater with high COD (Chemical Oxygen Demand), elevated phosphorus levels, and fluorine organic pollutants. This wastewater predominantly comprises organic phosphorus compounds, exhibiting less-than-favorable biochemical properties, often characterized by a B/C ratio of less than 0.06. These complexities necessitate the implementation of highly effective wastewater treatment strategies, not only to ensure environmental sustainability but also to safeguard the overall success and profitability of the project.
Enter the Boron Doped Diamond/BDD Electrode – a cutting-edge technology that holds tremendous promise in addressing these wastewater treatment challenges. The application of BDD electrode in the treatment of water contaminated with organic pollutants, including phosphorus compounds, has gained traction in recent years. BDD electrodes are known for their exceptional electrochemical oxidation capabilities, which can efficiently break down a wide range of organic pollutants, even those with poor biochemical properties.
In the context of the Guangxi Pengyue Ecological Technology Co., Ltd. project, the incorporation of BDD electrode into the lithium battery recycling wastewater treatment process can be a game-changer. The high-efficiency electrochemical oxidation facilitated by BDD electrode was introduced as tertiary treatment, electro-oxidation process can effectively degrade the recalcitrant organic phosphorus compounds present in the wastewater. This not only reduces the overall phosphorus content but also improves the water quality, ensuring compliance with stringent environmental regulations. Boromond introduced pilot treatment module as tertiary treatment using electro oxidation
Furthermore, the application of BDD electrode can lead to the removal of other organic pollutants, such as fluorine-containing compounds, contributing to a more comprehensive and efficient wastewater treatment process. This not only addresses the immediate challenges faced by the project but also aligns perfectly with the goal of achieving sustainable development by minimizing the environmental footprint of the entire operation.
Pengyue wastewater treatment project represents holistic approach to resource utilization and waste management showcases a commitment to sustainability. With the incorporation of boron-doped diamond/BDD electrode for wastewater treatment, this project not only overcomes the challenges posed by high COD, phosphorus, and fluorine organic wastewater but also sets a new standard for environmentally responsible industrial practices. As this technology continues to advance, it promises to play a pivotal role in shaping the future of water treatment and sustainable development in the phosphorus chemical industry.
