本研究的目的是开发一种通过生物洗涤器从沼气中去除硫化氢 (H2S) 的工艺。本研究中的实验室规模生物洗涤器系统是一个 0.05 L 吸收盘塔，配有一个 1.5 L 生物氧化反应器，接种了来自当地废水处理厂的硫氧化剂。研究了不同入口 H2S 浓度和不同空床停留时间 (EBRT) 下生物橡胶的性能。 EBRT 63 s 时，H2S 浓度从 407 变化到 4153 ppmv，对应于入口 H2S 负载率为 32–326g H2S m− 3 h− 1。入口负载率为 37g H2S m− 3 h− 1 时，生物洗涤器的最大去除效率为 80%。在入口负荷率为 320g H2S m− 3 h− 1 时，生物洗涤器的最大去除能力为 160g H2Smm− 3 h− 1。在 EBRT 为 63、79、90 和 105 s 时，1000ppmv H2S 沼气的最大去除效率分别为 75、89、93 和 99%。生物洗涤器对二氧化碳的去除也几乎没有影响。约 2% 的二氧化碳也从沼气中被去除，而未经处理的沼气的二氧化碳浓度约为 10-12%。总体而言，生物洗涤器可能是另一种环保手段，无需使用危险化学品即可提高受 H2S 污染的沼气质量。 http://dx.土井。 org/10.1016/j。科比奥。 2013.05. 183
The objective of this study is to develop a process to remove hydrogen sulfide (H2S) from biogas by bioscrubber. The laboratory scale bioscrubber system in this study was a 0.05 L absorption tray tower with a 1.5 L biological oxidation reactor inoculated with sulfur oxidizer from a local waste water treatment plant. The performances of biosrubber were studied in different inlet H2S concentrations and different empty bed residence times (EBRT). H2S concentrations were varied from 407 to 4153 ppmv at EBRT of 63 s corresponded to inlet H2S loading rate of 32–326g H2S m− 3 h− 1. The maximum removal efficiency of the bioscrubber was 80% at 37g H2S m− 3 h− 1 inlet loading rate. The maximum elimination capacity of the bioscrubber was 160g H2Smm− 3 h− 1 at an inlet loading rate of 320g H2S m− 3 h− 1. The maximum removal efficiency of 1000ppmv H2S biogas was 75, 89, 93 and 99% at EBRT of 63, 79, 90 and 105 s respectively. The bioscrubber also had little effects on carbon dioxide removal. About 2% of CO2 was also removed from the biogas stream while the CO2 concentration of untreated biogas was around 10–12%. Overall, the bioscrubber may be another environmental friendly mean to improve the quality of H2S contaminated biogas without the necessity to use hazardous chemicals. http://dx. doi. org/10.1016/j. copbio. 2013.05. 183
