Biological treatment of dimethyl sulphide (DMS) was investigated in a bench-scale biofilter, packed with compost along with wood chips, and enriched with DMS degrading microorganism Bacillus sphaericus. The biofilter could remove 62-74% of the inlet DMS, at an optimum loading of 0.484 g/m(3)/h with optimum empty bed contact time (EBCT) of 384 s and an average moisture range of 65-70%. The biodegradative products of DMS were sulphide, thiosulphate and sulphate. Evaluation of microbiological status of the biofilter indicated the presence of other bacterial cultures viz. Paenibacillus polymyxa, and Bacillus megaterium, besides B. sphaericus.
采用填充有堆肥和木屑并富含 DMS 降解微生物球形芽孢杆菌的生物滤池对二甲基硫（DMS）进行生物处理，在最佳进气负荷 0.484 g/m(3)/h、最佳空床接触时间（EBCT）384 s 和平均湿度范围 65-70%的条件下，生物滤池对 DMS 的去除率为 62-74%。DMS 的生物降解产物为硫化物、硫代硫酸盐和硫酸盐。对生物滤池微生物状况的评估表明，除了球形芽孢杆菌外，还存在其他细菌，如多粘芽孢杆菌和巨大芽孢杆菌。
