A biochemical oxygen demand (BOD) sensing system using the combination of
three-electrode electrochemical detector, seed obtained from the activated sludge,
and flow injection analysis system (FIA) was developed in this study to examine the
BOD of wastewater. The detector contained an Ag/AgCl electrode (Reference electrode, RE) and a
Pt electrode (Working electrode, WE), which was coated with 20 LNafion to reduce
noises. The reactor was fabricated with acrylic plastic, and the activated sludge was
placed in an 18 mm (L) 2 mm(W) 2 mm (D) cave, in which the tested sample was
reacted and detected with the above electrodes through the flow injection analysis
system. Standard curves were built from the experimental data for both GGA
(Glucose-glutamic acid) synthetic wastewater and swine wastewater by different
approaches: end-point, constant-time, quasi-kinetic I, and quasi-kinetic II,
To verify the efficacy of this system, wastewater collected from pig farm was
tested. The results showed that, when using the standard curves generated by GGA
wastewater, the constant-time and quasi-kinetic I had better performance in
estimating the BOD concentration, with the deviations of 9.0% and 7.7%, respectively.
In addition, when using the standard curves generated by the swine wastewater, the
end-point, constant-time and quasi-kinetic I hadmuch better estimate than the above,
with the deviations of 0.8%, 2.5%, and 1.7%, respectively.
