Ventilation, Turning and Additive Effects on Odor Emissions and Municipal Solid Waste (MSW) Bio-Drying

Abstract:

A series of biological drying and odor emissions experiments of municipal solid waste (MSW) was made by using independently developed biological drying device. . The results show that: Ventilation increasing contributes to the loss of water and reduction of H₂S emission, as well as conducive to biochemical reactions. Additives of T2 and T4 can significantly reduce the emission of H₂S and additives of T2 and T3 can significantly reduce the emission of NH₃, thus, T2 can preferably chose as biodrying deodorant. Turning process has a certain impact on the biodrying product moisture content, moisture content decreases with the increase of turning times, the moisture of final biodrying product reached 25% when turning twice, reached 22.5% when turning 3 times and, reached 19.1% when turning 4 times. Thus, increase the turning times can significantly reduce moisture content.
