Abstract:In this paper the composition and properties of EfOM in biological effluent of pulp and paper wastewater and the removal behavior of EfOM by Fenton process were studied. Results showed that hydrophobic organic fractions predominated in EfOM, especially hydrophobic acid, its CODCr and UV254 were 64% and 53%, respectively. The EfOM mainly contained the substances with apparent molecular weight (AMW) higher than 10000. EfOM was effectively removed by Fenton process. The recommended dosage was 0.5 Qth, pH was 3, [H2O2]∶[Fe2+] was 5∶1, and the reaction time was 20 min, the effluent of Fenton process could meet the discharge requirement of the regulation. The main organic matter of effluent of Fenton process was hydrophobic acid, the next was hydrophilic matters, the organic matters with high molecular weight were removed effectively, about 60% of organic matters of the effluent were with AMW lower than 3000. |
