The co-digestion of multiple substrates is a promising method to increase methane production during anaerobic digestion. However, limited reliable data are available on the anaerobic co-digestion of food waste leachate with microalgal biomass. This report evaluated methane production by the anaerobic co-digestion of different mixtures of food waste leachate, algal biomass, and raw sludge. Co-digestion of substrate mixture containing equal amounts of three substrates had higher methane production than anaerobic digestion of individual substrates. This was possibly due to a proliferation of methanogens over the entire digestion period induced by multistage digestion of different substrates with different degrees of degradability. Thus, the co-digestion of food waste, microalgal biomass, and raw sludge appears to be a feasible and efficient method for energy conversion from waste resources.
混合多种底物进行共消化是提高厌氧消化过程中甲烷产量的一种很有前途的方法。然而，关于用微藻生物质与食物垃圾渗滤液进行厌氧共消化的可靠数据有限。本报告评估了不同比例的食物垃圾渗滤液、藻生物质和原污泥混合物的厌氧共消化过程中甲烷的产生情况。含有等量三种底物的共消化混合物的甲烷产量高于单独消化各底物的甲烷产量。这可能是由于不同可降解程度的多种底物进行多级消化，导致整个消化过程中产甲烷菌大量繁殖。因此，将食物垃圾、微藻生物质和原污泥进行共消化似乎是一种从废物资源中进行能量转换的可行且有效的方法。
