The evolution of phosphine gas during the anaerobic batch fermentation of fresh swine manure was detected and correlated to the production of methane and hydrogen sulphide. A close temporal relationship between phosphine liberation and methane formation was found. However, the gaseous phosphine released from manure during fermentation only represents a tiny fraction of the overall phosphine balance. The majority of phosphine is captured in solid manure constituents. This matrix-bound phosphine is eliminated by more than 50% during anaerobic batch-fermentation. Seasonally determined phosphine concentrations in biogas and manure from two large-scale manure treatment plants also revealed net losses of phosphine in fermentation. Consequently, manure has to be considered more as a sink of phosphine rather than a phosphine-generating medium. Furthermore, a close relationship between phosphine in the feed of swine and manure of these swine was observed, implying that phosphine residues in the feed (possibly as a result of grain fumigation) represent an important source of phosphine in manure technologies that is relevant before the faecals of swine enter manure treatment plants.
检测了新鲜猪粪厌氧分批发酵过程中磷化氢气体的逸出情况，并将其与甲烷和硫化氢的产生进行关联。发现磷化氢释放与甲烷形成之间存在密切的时间关系。然而，发酵过程中从粪便释放的气态磷化氢仅占总磷平衡的一小部分。大部分磷化氢被捕获在固体粪便成分中。在厌氧分批发酵过程中，这种与基质结合的磷化氢被去除了50%以上。对两个大型粪便处理厂的沼气和粪便中季节性测定的磷化氢浓度也显示，发酵过程中磷化氢有净损失。因此，粪便应更多地被视为磷化氢的汇而非产生磷化氢的介质。此外，观察到猪饲料中的磷化氢与这些猪的粪便之间存在密切关系，这意味着饲料中的磷化氢残留（可能是谷物熏蒸的结果）是粪便处理技术中磷化氢的一个重要来源，这在猪粪便进入粪便处理厂之前就很重要。
