Guangxi Pengyue Ecological Technology Co., Ltd,a subsidiary of Guizhou Chanhen Chemical Corporation, 002895 (SHE),a publicly listed company and pioneer of the phosphate industry. The project revolves around the concept of “copper, sulfur, and phosphorus”, with a primary focus on utilizing phosphate ore as the main raw material. By consuming sulfuric acid, which is a by-product of copper electrolysis, the project effectively treats the waste acid generated during the copper electrolysis process. This innovative approach addresses the challenges faced by two major industries – copper electrolysis and the phosphorus chemical industry – and aims to achieve sustainable development for both. The production process for phosphoric acid is based on the hemi-dihydrate wet process, which is then further refined to produce high-purity phosphoric acid, calcium dihydrogen phosphate, ferric phosphate, and other valuable by-products.However, the project does encounter challenges, particularly concerning high COD (Chemical Oxygen Demand), high phosphorus, and fluorine organic wastewater. The wastewater primarily contains organic phosphorus, which exhibits poor biochemical properties with a B/C ratio less than 0.06. These complexities demand effective wastewater treatment strategies to ensure environmental sustainability and the overall success of the project.
