The conventional Fenton fluidized bed system experienced severe corrosion, inefficient operation, and poor treatment performance due to its rough and outdated setup.
Solution：To address issues with the original conventional Fenton fluidized bed process, including severe corrosion, rough operation, and poor performance, a series of bench-scale tests were conducted. Despite testing multiple AOP technologies, the Fenton process remained the only viable option. Drawing on our extensive engineering experience, we designed the new system to replace manual operation with automated control, dynamically adjust chemical dosing based on influent water quality, and use waste heat for temperature regulation to maintain optimal reaction conditions. This precise and adaptive control ensured effective treatment performance while reducing operational costs.
Processing Scale：350m3/d
Treatment Effect：The equipment design, installation, and commissioning were completed within 35 days, with the COD removal rate reaching 50%–60%. The system operates with stability and controllability, effectively breaking pollutant chains and reducing biological treatment impact. As a result, the plant achieved an additional reduction of 6 tons of pollutants per year, bringing notable environmental benefits.
