摘  要:
为研究微量金属元素对牛粪厌氧发酵特性的影响,每隔1,3,5,7d向牛粪厌氧发酵液中添加Fe、Co、Ni元素。结果表明,7d添加1次微量金属元素的发酵组效果最佳,产气率和总产气量最高,COD去除率最高;每1d添加1次的挥发性有机酸(VFA)和产气量都最低,分析认为微量金属元素添加频率过高会破坏反应器内的营养平衡。

摘  要:
In order to research the effects of trace metal elements on the anaerobic fermentation characterization of dairy manure,Fe,Co,Ni was added into the anaerobic fermentation reactor on every 1,3,5,7 days.Theresults showed that a appropriate frequency of the addition trace metals is every seven days.It′s biogas rate and the COD removal rate is the highest.In the reactor by swinging trace metals every day the biogas production is the lowest,perhaps a redundant supplement of trace metals could cause toxic.
