以辣椒为原料,以实验室长期驯化的猪粪发酵残留物为底物的混合厌氧消化污泥作为接种物,在常温下进行批量发酵,发酵料液体积400 ml,RHT=86 d.TS质量分数为6.36%时,进行厌氧发酵产H2,产H2结束后使用NaOH溶液调节pH值为7.42,继续发酵产CH4.结果表明:辣椒产氢潜力(TS)为103.0L/kg,VS产氢潜力145.7 L/kg;TS产甲烷潜力为254.6 L/kg,VS产甲烷潜力为276.9 L/kg,其TS能量利用潜力达2 222.4 kJ/kg. 相似文献

用搅拌式电感耦合等离子体反应器对高密度聚乙烯(HDPE)粉体进行表面处理,采用水接触角、红外光谱(FT-IR)和X射线光电子能谱(XPS)对等离子体处理前后HDPE粉体的水接触角、表面成分的变化进行分析。实验结果表明,随着等离子体处理时间延长和放电功率增加,水接触角减小。在功率100W处理30min后,水接触角从处理前... 相似文献

A synergistic photocatalysis combined pulsed diaphragm discharge(PDD)system with TiO2 nanofilm deposited on the surface of quartz diaphragm is developed for the first time for phenol degradation in an aqueous solution.It is observed that the decomposition efficiency of phenol in the TiO2 combined PDD system is higher than that of the single PDD system under the same conditions,indicating a successful collaboration between the photocatalysis and the plasma decomposition in the present system.Analysis of the solution’s pH value confirms this collaboration and further reveals that the photocatalytic enhancement effect of phenol degradation is strong at a relatively low supplied voltage.The present TiO2 combined PDD system exhibits improved efficiencies of pollutant degradation and energy utilization,suggesting a good candidate for wastewater treatment. 相似文献
