Qingdao Phoenix Dyeing and Printing Co., Ltd.
The raw water contains a significant amount of aniline substances, which has a major impact on the biochemical process. Our company’s self-developed LEM micro-electrolysis catalytic oxidation technology is used to break the chemical bonds of toxic and harmful substances, effectively reducing the toxicity of the raw water and improving the wastewater B/C ratio. This lays a solid foundation for the normal operation of the entire process.
Products: Terephthalic Acid, Acetic Acid, Dimethylformamide (DMF), Dimethylacetamide (DMAC), Xylene, Dyes, Aniline
Wastewater Quality: The treatment process successfully reduced the COD from 300 mg/L to 100 mg/L and removed the color to achieve a colorless effluent.
Overall Wastewater COD: 3,000 mg/L
Final Effluent COD: ≤ 100 mg/L
Influent COD of Micro-Electrolysis Process: 32,000 mg/L
Effluent COD after Flocculation and Sedimentation: ≤ 8,000 mg/L
Removal Efficiency: 75%
Influent Water Volume : 500 m³/d
Process Description: High-Concentration Water Equalization Tank + Acidic Air Flotation + Micro-Electrolysis + Fenton + Coagulation + Comprehensive Water Tank + Hydrolysis Acidification + A/O Process (Anaerobic/Oxic)
