- Abstract:
- Fenton three-phase catalytic oxidation advanced treatment process was applied for upgrading and reconstruction of a wastewater treatment plant in a dyeing and printing industrial park in Shaoxing. The process stably reduced the effluent COD of air flotation process from 112 mg/L to 27 mg/L, and the effluent COD of biochemical process from 227 mg/L to 36 mg/L. All other indexes met the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). In addition, the process flow, characteristics and design parameters of each treatment unit were introduced in detail, and the main economic indicators were analyzed, which aimed to provide reference for dyeing and printing wastewater treatment projects.
