Abstract [en]
The purpose is to develop a complete microbiological model system for the treatment of wastewater
from textile mills in developing countries. Arti
fi
cial wastewater was treated by microorganisms growing
on wood shavings from Norway spruce during unsterile conditions. The microorganisms were inoculated
from forest residues. Mixtures of the azo dyes Reactive Black 5 and Reactive Red 2 were degraded in
batch as well as continuous experiments. Reactive Red 2 mixed with the anthraquinone dye Reactive
Blue 4 was also treated in the continuous system. The system consisted of three reservoirs
e the fi
rst two
with an anaerobic environment and the third with an aerobic. The dye concentrations were 200 mg l
1
of
each dye in the continuous system and the retention time was approximately 4 days and 20 h per
reservoir. Samples from the process were analysed with spectrophotometer and LC/MS to monitor the
degradation process. 86-90% of the colour was removed after a treatment of 4 days and 23 h in the
continuous process. Two metabolites were found in the outlets of reactors one and two, but they were
degraded to below the detection limit in the aerobic reactor.
