| 摘 要： | 文章研究了利用厌氧消化技术处理黑木耳生产残留物.采用序批式厌氧消化方式,分别对pH值,产气量,CODCr,进出料TS,VS,粗纤维、凯氏氮等进行测试分析.试验表明:以黑木耳生产残留物为厌氧消化原料,若接种物不足,易产生酸化.厌氧消化料液浓度(TS)15％时,累计总产气量最高,为14876 mL,分别比厌氧消化料液浓度6％,9％和12％时高出23.90％,11.12％和11.26％,说明在实验条件下,黑木耳生产残留物厌氧消化的浓度越高,产气越多.4组处理的出料CODCr浓度相对于进料时分别降低了31.45％,33.75％,36.67％和36.53％.得出黑木耳生产残留物中可被厌氧微生物降解的有机物含量平均为35％左右.厌氧消化液浓度15％时的TS和VS降解率均最大,分别为43.82％和47.42％.4组处理的粗纤维降解率大致相同,平均在57％左右.四组处理的出料干物质中凯氏氮的含量比进料均有所增加.

| Abstract: | Anaerobic fermentations of black fungus production residue were conducted at fermentation TS concentration of 6%,9%,12%,and 15% in this sdudy.Batch fermentation was adopted.The gas production,CODCr,TS and VS of influent and effluent,crude fiber,pH,and TKN were determined and analyzed.The result showed that acidification would be appeared during the anaerobic fermentation if the inoculum was insufficient.The highest accumulated gas production(14876 mL) was obtained when the TS concentration of fermentation w... |
