英文摘要 | Large amounts of NH3 and H2S are emitted during sewage sludge composting, resulting in odor pollution. This composting experiment was carried out using sewage sludge mixed with sawdust, and different amounts of zero-valent iron (ZVI) were added to investigate the effect on volatile gases, such as NH3 and H2S, and to analyze the effect on the available sulfur, total sulfur, moisture content, and germination index of the compost. The results showed that the addition of ZVI during the composting process had noticeable effects on the emission of NH3 and H2S. ZVI could also increase the heating rate and peak temperature of the pile, reduce the available sulfur loss, and promote the dewatering and decomposition of the compost pile. The addition of 3% ZVI had the best effect on NH3 emissions; it reduced the peak concentration of NH3 release during composting by 21.0% compared to the blank group. However, the addition of 2% ZVI was the most effective for H2S emissions; it reduced the peak release concentration of H2S by 20.0%. A higher addition of ZVI was more effective in reducing the moisture content and increasing the germination index of the compost. |
