The effect of bentonite-bound oil on thermophilic anaerobic digestion of cattle manure was investigated. In digestor experiments, addition of oil was found to be inhibitory during start-up and the inhibitory effect was less pronounced when the oil was added in the form of bentonite-bound oil compared to when the oil was added alone. After adaptation of the digestors, very rapid degradation of oil was observed and more than 80% of the oil was degraded within a few hours after daily feeding. In batch experiments, glyceride trioleate was found to be inhibitory to thermophilic anaerobic digestion when the concentrations were higher than 2.0 g/l. However, addition of bentonite (a clay mineral) at concentrations of 0.15% and 0.45% was found to partly overcome this inhibition. Addition of calcium chloride in concentration of 3 mM (0.033% w/v) showed a similar positive effect on the utilization of oil, but the effect was lower than with bentonite.
研究了膨润土结合油对牛粪高温厌氧消化的影响。在消化器实验中，发现添加油在启动阶段具有抑制作用，与单独添加油相比，以膨润土结合油的形式添加时抑制作用不那么明显。消化器适应后，观察到油的降解非常迅速，每天进料后几小时内超过80%的油被降解。在批次实验中，发现当甘油三油酸酯浓度高于2.0 g/l时对高温厌氧消化有抑制作用。然而，发现添加浓度为0.15%和0.45%的膨润土（一种粘土矿物）可部分克服这种抑制作用。添加浓度为3 mM（0.033% w/v）的氯化钙对油的利用也有类似的积极作用，但效果低于膨润土。
