ADVANCED TREATMENT OF PULPING & BLEACHING EFFLUENT WITH FE-CA BIOMIMETIC SYSTEM
In recent years, Fe-based biomimetic system which can simulate the function of lignin peroxidase is a hot topic in effluent treatment concerned with the paper industry. The ability of decolourization and degradation of residual lignin in the effluent by the Fe-based biomimetic system was investigated. The pulping and bleaching effluent was treated with Fe-carboxyl acid (Fe-CA) biomimetic system and followed by polymeric ferric sulfate (PFS) flocculation. It was found that removal of CODcr and chroma achieved 73％ and 80％ respectively. Meanwhile, the optimal condition of wastewater treatment was as follows: 10mg/L of Fe-CA; 200mg/L of PFS; 150mg/L of H2O2; pH6.0; 30 ; reaction time 1h and ℃ sedimentation time 3h. Because of the merit of stable property, lower cost and high efficiency, the Fe-CA complexes will be widely used in advanced treatment of wastewater from paper mills.
