| 摘 要： | 采集滇池白山湾、滇池草海、太湖(武进段水域)以及江苏省农科院2号塘生长的凤眼莲,进行了批式厌氧发酵对比试验研究.结果发现,凤眼莲的产气潜力和水体氮磷水平有关系.水体氮磷浓度最高的滇池草海凤眼莲产气量最高,为390mL/gTS(498mL/gVS);水质最好的滇池白山湾的凤眼莲产气量最低,为289mL/gTS(334mL/gVS).白山湾凤眼莲的纤维素、半纤维素和粗蛋白等组分的降解率均最低.4个水体凤眼莲产生的有机酸均以乙酸和丙酸为主,草海凤眼莲发酵产生的有机酸浓度最高,可达2466mg/L,白山湾凤眼莲最低,仅为915mg/L.研究发现水体氮、磷浓度影响凤眼莲化学组分含量的差异及结构组成(根冠比),可能是影响凤眼莲厌氧生物降解性能及产气量差异的主要因素.

| Abstract: | To investigate the influences of nitrogen(N) and phosphorus(P) in water on the biogas production digested by water hyacinth,plants from Baishan Bay and Caohai Lake in Dianchi Lake,Wujin Region in Taihu Lake,and Pond Two in Jiangsu Academy of Agricultural Sciences were collected to conduct a mesophilic batch anaerobic digestion experiment.Results showed that the methane productivity from water hyacinth had significant correlation to the concentrations of N and P in waters.The highest biogas production was fr... |
