Vooronderzoek naar de emissies van lachgas, ammoniak, methaan en aerosolen uit een mestbeluchtingsunit
A preliminary study was conducted into the emissions of N2O, NH3, CH4 and aerosols at two manure aeration treatment plants. Aim of the study was to determine to what extent harmful substances can emit from an aeration unit for the production of ammonia and odour-free liquid. Measurements were done according the dynamic box method for determining the emissions of gases and concentration measurements were carried out for aerosols (bacteria and endotoxins). It was determined that the emissions of ammonia were virtually zero (measured 0.087 g per m3 manure). Greenhouse gas emissions (CH4 and N2O) were also low and barely measurable in our measurement setup. Based on our measurements, the emission can vary between 0 and 39 g CO2 equivalents per m3 of slurry. For fattening pigs, a total CO2 footprint of 1 700 kg CO2 equivalents per animal place is assumed. Also,concentrations of bacteria E Coli, Enterococcus, and Sulphide reducing Clostridia (SSRC) were below (E Coli and Enterococcus) detection limit or low (SSRC). Endotoxin concentrations above the surface of the aeration tank were scarcely higher than the advice value for outside air of 30 EU/m3.

Er is een vooronderzoek uitgevoerd naar de emissies van N2O, NH3, CH4 en aerosolen bij twee mestbeluchtingsinstallaties. Doel van het onderzoek was om te bepalen in welke mate schadelijke stoffen kunnen emitteren uit een beluchtingsunit voor de productie van ammoniak- en geurvrije vloeistof. Voor het bepalen van de emissies van gassen is volgens de dynamische boxmethodegemeten en voor aerosolen (bacteriën en endotoxines) zijn concentratiemetingen uitgevoerd. Bepaald is dat de emissie van ammoniak nagenoeg nul is (0,087 g per m3 mest). De emissies vanbroeikasgassen (CH4 en N2O) waren ook laag en nauwelijks meetbaar in onze meetsetup. Op basis van onze metingen kan de emissie variëren tussen 0 en 3 9 g CO2 equivalenten per m3 drijfmest. Voorvleesvarkens wordt uitgegaan van een totale CO2 footprint van 1 700 kg CO2 equivalenten per dierplaats. Ook concentraties van de bacteriën E Coli, Enterokokken en Sulfiet reducerende Clostridia (SSRC) waren niet detecteerbaar (E Coli, Enterokokken) of laag (SSRC). Endotoxine concentraties direct boven de mestbehandelingstanks waren nauwelijks hoger dan de advieswaarde van maximaal 30 EU/m3 voor de buitenlucht. nl Wageningen Livestock Research application/pdf https://research.wur.nl/en/publications/vooronderzoek-naar-de-emissies-van-lachgas-ammoniak-methaan-en-ae 10.18174/531067 https://edepot.wur.nl/531067 Life Science https://creativecommons.org/licenses/by-nc/4.0/ Wageningen University & Research |
