The effects of sulphur and Thiobacillus thioparus 1904 on odour emissions during composting were studied. Results indicated that the sulphur addition reduced the pH and decreased cumulative emission of ammonia and the nitrogen loss by 47.80% and 44.23%, respectively, but the amount of volatile sulphur compounds (VSCs) and the sulphur loss increased. The addition of T. thioparus 1904 effectively reduced the cumulative emissions of HS, methyl sulphide, methanethiol, dimethyl disulphide and the sulphur loss by 33.24%, 81.24%, 32.70%, 54.22% and 54.24%, respectively. T. thioparus 1904 also limited the nitrogen loss. The combined application of sulphur and T. thioparus 1904 resulted in the greatest amount of nitrogen retention. The accumulation of ammonia emissions was reduced by 63.33%, and the nitrogen loss was reduced by 71.93%. The combined treatment did not increase the emission of VSCs. The application of sulphur and T. thioparus 1904 may help to control the odour of compost.
研究了硫磺和 Thiobacillus thioparus 1904 对堆肥过程中恶臭排放的影响。结果表明，添加硫磺降低了 pH 值，使氨的累积排放量和氮损失分别减少了 47.80%和 44.23%，但挥发性硫化合物（VSCs）和硫的损失增加。添加 T. thioparus 1904 可有效减少 HS、甲硫醚、甲硫醇、二甲基二硫和硫损失的累积排放量，分别减少了 33.24%、81.24%、32.70%、54.22%和 54.24%。T. thioparus 1904 还限制了氮的损失。硫磺和 T. thioparus 1904 的联合应用导致氮的保留量最大。氨排放的积累减少了 63.33%，氮损失减少了 71.93%。联合处理并没有增加 VSCs 的排放。硫磺和 T. thioparus 1904 的应用有助于控制堆肥的气味。
