| Summary: | This research is investigated the efficiency of Advanced Oxidation Processes
(AOP) (Fenton and photo-Fenton processes), enzymatic treatment, and
combined enzymatic/ AOP sequences on colour removal of soda and
Chemical Mechanical Pulping (CMP) effluent samples from two major pulp
and paper mills in Iran. In addition, the effect of AOP as a pre-treatment unit
and post-treatment unit in conjuction with biological treatment, in the
combined treatment system, were investigated.
Results indicated that, under all circumstances, Fenton process using UV
irradiation (photo-Fenton) was found to be more efficient in the degradation
of effluent components, compared to the dark reaction.UPLOAD Regarding the enzymatic treatment, two kinds of fungal enzymes; Laccase
(EC: 1.10.3.2) from Terametes Versicolour and Versatile Peroxidase (EC:
1.11.1.7) from Bjerkandera adusta were selected and used. In order to
determine the effect of enzyme dosage on the overall efficiency of
decolourization, experiments were carried out at 2 dosages (1 mg & 2 mg) for
each enzyme. To evaluate the effect of external mediator on the enzyme
based degradations, each enzyme was applied on the effluent samples, one
with the presence of external mediator, and the other, without it, while the
other conditions were the same. |
