不同形态水葫芦和污泥联合厌氧消化产沼气性能
|
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.
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 of8% 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.
