Challenges
Papermaking wastewater is a typical high-concentration industrial wastewater.
The main challenges include:
- High COD concentration
- High fiber suspended matter content
- High color intensity
- Wastewater temperature is high
- Significant impact loads
- Strict emission standards
Our Solution
A complete paper manufacturing wastewater treatment system is adopted.
Process route:
Coarse Grid → Fine Grid → Inclined Screen → Regulation Tank → Cooling Tower → Flocculation and Sedimentation → DAF Flotation → Hydrolytic Acidification → IC Anaerobic Reactor → A/O Biochemical System → Secondary Sedimentation Tank → Fenton Advanced Treatment → Compliant Discharge
Equipped with 4 large IC reactors to treat high-concentration organic wastewater.
Technical Highlights
- Multi-stage pretreatment system
- High-efficiency IC anaerobic technology
- Deep decarbonization process
- Fenton Deep Processing
- Stable operation under high load
