“…Common control technologies include combustion (Ye et al, 2012) and non-combustion technologies mostly using chemical reaction and purification to treat air pollutants (Hsieh et al, 2011;Latif et al, 2011;Lo et al, 2011;Perng et al, 2011). As odorous compounds being the target pollutants for air treatment, absorption/adsorption scrubbing (Gaur et al, 2010;Panza and Belgiorno, 2010) and biological treatment including biofiltration and biotrickling filters (Melse and Van der Werf, 2005;Popat and Deshusses, 2008;Chou and Li, 2010) were widely used. However, absorption/ adsorption technologies typically focused on certain compounds, and the degrees of decontamination depended largely on sorption mechanisms, types of solvents, the pH, equilibrium time, etc.…”
