DMS Removal in a Bubble Reactor by Using Peroxone (O_3/H_2O_2) Reactions

摘要

Emissions of reduced organic sulfur compounds from livestock facilities can cause severe odour nuisance to residents living in the vicinity, and development of abatement technologies is necessary. The aim of the present study was to investigate the removal effect of dimethyl sulfide (DMS) by using the peroxone reactions (O_3/H_2O_2), an advanced oxidation process which can produce OH· radicals. A bubble reactor was tested under different processing conditions and the concentration of DMS was continueously measured by an online proton-transfer-reaction mass spectrometry (PTR-MS). Under all the conditions, the removal was higher than 90 %. In conclusion, this study demonstrated the feasibility of utilizing peroxone system as an OH· radical source in a bubble reactor, and it could also be helpful to optimise a wet compact scrubber following the abatement of offensive odorous pollutants in the future study.
