  • 摘要: 为探求不同形态水葫芦和污泥联合厌氧消化产沼气性能，在中温35±1℃条件下，设置了2个不同的TS浓度（TS=6%和8%），采用不同形态的水葫芦（水葫芦段、水葫芦浆、水葫芦渣、水葫芦粉和水葫芦汁）与污泥进行联合厌氧消化实验.结果表明，水葫芦和污泥联合厌氧消化的累积产甲烷量均高于对照组；添加水葫芦处理的累积产甲烷量从大到小依次为水葫芦渣 > 水葫芦浆 > 水葫芦段 > 水葫芦粉 > 水葫芦汁，水葫芦渣处理的累积产甲烷量比水葫芦汁提高62.5%（TS=6%）和84.5%（TS=8%）；系统TS浓度为8%时，各处理的TS甲烷产率均高于TS浓度为6%的结果，且水葫芦渣和污泥联合厌氧消化的产甲烷性能最好，表明水葫芦的压滤和粉碎有助于提高厌氧消化的产甲烷潜力.
    Abstract: In order to investigate biogas production performance by anaerobic co-digestion of different forms of water hyacinth and sewage sludge, anaerobic co-digestion experiments of sewage sludge with different forms of water hyacinth(water hyacinth segment, water hyacinth pulp, water hyacinth residue, water hyacinth powder and water hyacinth juice) were conducted under mesophilic condition 35±1℃ with TS content of 6% and 8%. The results showed that the cumulative methane production by anaerobic co-digestion of water hyacinth and sludge was higher than that of the control with an order of water hyacinth residue > water hyacinth pulp > water hyacinth segment > water hyacinth powder > water hyacinth juice. The cumulative methane production, with water hyacinth residue addition increased by 62.5%(TS=6%) and 84.5%(TS=8%) by comparison with the production with water hyacinth juice addition. The TS methane production rate of treatments with TS content of 8% was higher than that of 6%. Therefore, when TS content was 8%, water hyacinth residue was the best form for anaerobic digestion, indicating that filter-pressing and crushing of water hyacinth will effectively improve the biochemical methane potential(BMP) of anaerobic digestion.
