Polymer Composite Gel Biocarriers Elevating Bioremediation Performance With Innovative Composite Technology
Introduction
Advanced Biofilm Carrier for Enhanced Nitrogen/Phosphorus Removal and Recalcitrant Pollutant Degradation
This innovative biofilm carrier is specifically engineered to address three critical wastewater treatment challenges: efficient nitrogen removal, enhanced phosphorus elimination, and degradation of persistent organic pollutants. The technology combines two breakthrough mechanisms
Hydrogel Sustained-Release System
Maintains optimal moisture and nutrient levels for microbial communities
- Gradually releases iron ions to ensure long-term catalytic activity (5-7 years)
- Protects functional microorganisms from harsh environmental fluctuations
- Active Iron Ion Catalysis Technology
- Iron ions interact with endogenous H₂O₂ (produced during microbial metabolism) to trigger Fenton-like reactions, generating hydroxyl radicals (·OH) that:
- Oxidize refractory COD (85-92% removal efficiency)
- Degrade antibiotics (e.g., sulfonamides, 80-90% removal)
- Break down micro-pollutants (pharmaceuticals, pesticides)
- Simultaneously functions as an electron mediator to:
- Accelerate denitrification by 40-60% compared to conventional carriers
- Promote chemical phosphorus fixation through iron-phosphate precipitation

FAQ
Q1: How does PCG compare to traditional plastic bio carriers?
PCG offers a larger surface area, better oxygen transfer, and faster biofilm growth due to its hydrophilic properties.
Q2: What is the expected lifespan of PCG?
Under normal conditions, PCG lasts over 10 years without significant wear.
Q3: Can PCG be used in anaerobic systems?
Yes, it is adaptable to both aerobic and anaerobic environments.
Q4: How much PCG media is needed per m³ of reactor?
The filling ratio typically ranges from 30% to 70%, depending on the system design.
Q5: Is PCG suitable for high-salinity wastewater?
Yes, it performs well in saline conditions, making it ideal for industries like seafood processing.
