摘要

摘要: 填埋场覆土中甲烷氧化菌的生物氧化作用,是填埋场CH₄最主要的自然减排途径,但通常传统的覆土材料CH₄氧化能力并不足。生物炭可用于强化填埋场覆土的CH₄氧化性能,同时,填埋气中的硫化氢(H₂S)也易被生物炭吸附转化,可能为CH₄氧化带来潜在影响,需要进一步探究和揭示。在前期实验基础上,设计了一种生物炭改性覆土材料,接种富集的甲烷氧化菌菌液后,分别于4种不同H₂S浓度(0、0.01%、0.025%和0.1%,体积分数)下进行4个周期的CH₄氧化孵化实验。结果表明:随着H₂S浓度的增加,生物炭改性覆土的CH₄氧化能力先减弱再增强最后再减弱:0.01%H₂S下,CH₄氧化相较于无H₂S组降低11.5%;而0.025%H₂S下,CH₄氧化提升了17%;0.1%H₂S则显著抑制了CH₄氧化,使之降低了28.8%。结合CH₄氧化结果以及土壤理化性质变化,推断0.025%左右的低浓度H₂S可通过正向刺激甲烷单加氧酶提升生物炭改性覆土的CH₄氧化能力,而高浓度H₂S由于其微生物毒性及吸附氧化过程可能的氧气竞争,表现出对CH₄氧化明显的抑制。

Abstract: Biological oxidation of methane(CH₄) by CH₄-oxidizing bacteria in landfill cover soil(LCS) is the most important natural way to reduce CH₄ emission at landfills; however, the CH₄ oxidation capacity of the traditional LCS is usually insufficient. Studies showed that biochar can be used to enhance the CH₄ oxidation performance of LCS. Simultaneously, biochar also presents good adsorption and conversion of hydrogen sulfide(H₂S) in landfill gas, owning potential impact on CH₄ oxidation, which needs to be further investigated and revealed. Based on previous experiments, this study designed and adopted a biochar-amended LCS, inoculated it with enriched methane-oxidizing bacteria solution, and then carried out four-cycle CH₄ oxidation incubation experiments under four H₂S concentration conditions(0, 0.01%, 0.025% and 0.1% by volume). The results showed that as H₂S concentration increased, the CH₄ oxidation capacity first decreased, then increased, and finally decreased. Under 0.01% H₂S, CH₄ oxidation decreased slightly by 11.5%; while under 0.025% H₂S, CH₄ oxidation increased by 17.0%. However, 0.1% H₂S obviously inhibited CH₄ oxidation and reduced it by 28.8%. Combining the results of CH₄ oxidation and the changes in the physical and chemical properties of the soil, it was inferred that the increase of CH₄ oxidation capacity was attributed to the positive stimulation of methane monooxygenase at a low concentration of H₂S around 0.025%. While high H₂S concentration exhibited a significant inhibition of CH₄ oxidation, due to its microbial toxicity and possible oxygen competition during the adsorption and oxidation process.
