厌氧发酵是利用畜禽粪污资源化的重要手段.然而,牛粪中木质纤维素含量高、难以降解,导致其厌氧发酵产气效率低,限制了在牛粪中的应用.为优化牛粪厌氧发酵性能,拓宽原料来源,在中温(37℃)下进行不同比例白菜尾菜与牛粪混合的批次试验(混合比例为100∶0、75∶25、50∶50、25∶75 和0∶100).结果表明,与白菜混合发酵可以提高牛粪的厌氧发酵性能.当白菜与牛粪混合比例为75∶25 时,产甲烷潜能达到最大值(419 mL·g-1).此外,根据Gompertz模型的拟合结果,最佳混合比例下的累积甲烷产量、有效产甲烷时间和产甲烷速率均显著优于其他组.因此,白菜尾菜与牛粪混合厌氧发酵是实现较好产气效果的一种有效方法.
Anaerobic digestion is an essential method for resource utilization of livestock manure.However,the high content of refractory lignocellulose in cattle manure leads to the low efficiency of AD,which limits the application of this technology in cattle manure treatment.This study aimed to optimize the AD performance of cattle manure and broaden the substrate source for AD.A batch experiment conducted under mesophilic(37℃)conditions with different mixing ratios of cabbage waste and cattle manure(100∶0,75∶25,50∶50,25∶75,and 0∶100).The results showed that the AD performance of cattle manure improved by co-digestion with cabbage waste.A 75∶25 mixing ratio of cabbage waste to cow dung yielded methane up to 419 mL·g-1.Moreover,the Gompertz model's fitting results showed that the cumulative methane production,sufficient methane production time,and methane production rate under optimal mixing ratio were significantly superior to the other groups employed.The results showed that the anaerobic co-digestion of cabbage waste and cattle manure could achieve better biogas production.
