Zusammenfassung |
This study presents two methods for estimating methane emissions from
a waste water treatment plant (WWTP) along with results from a measurement
campaign at a WWTP in Valence, France. These methods, chamber measurements
and tracer release, rely on Fourier transform infrared spectroscopy
and cavity ring-down spectroscopy instruments. We show that the tracer
release method is suitable for quantifying facility- and some process-scale
emissions, while the chamber measurements provide insight into individual
process emissions. Uncertainties for the two methods are described and
discussed. Applying the methods to CH4 emissions of the WWTP, we confirm
that the open basins are not a major source of CH4 on the WWTP (about
10 % of the total emissions), but that the pretreatment and sludge
treatment are the main emitters. Overall, the waste water treatment plant is representative of an average French WWTP. |
