摘要
利用自行设计的厌氧发酵实验装置,对黄瓜茎叶和番茄茎叶在30±1℃恒温条件下,进行了单相批量厌氧发酵试验研究,结果表明:黄瓜茎叶随着厌氧发酵时间的延长,所产气体中的CH4含量呈明显升高的趋势,H2S含量接近线性变化,厌氧发酵2周后产气量达到最高,产气高峰期持续2～3周左右。番茄茎叶在厌氧发酵过程中产甲烷活性期出现较晚,H2S含量高于黄瓜茎叶10倍左右,产气高峰期比黄瓜茎叶推迟1周左右,持续时间较短,总产气量低于黄瓜茎叶。
A batches anaerobic digestion experiments for stems and leaves of cucumbers and tomatoes were conducted at 30±1℃. The results showed that the CH_4 contents produced by cucumber was increasing quickly along with the digestion going on , and the H2S contents decreasing in linear. The gas production peak reached after two weeks and it lasted 2～3 weeks. The H2S contents produced by tomato stems and leaves is ten times of that of cucumber. Its gas production peak was one week later than cucumber, and lasted shorter time. And the whole gas production was lower than that of cucumber.
