The Effect of Food-Microorganism(F/M)Ratio on Gas Properties in Batch Biogas Fermentation with Walnut Peel

Abstract:

In order to study the effect of food-microorganism (F/M) ratio on gas properties in batch biogas fermentation experiments with walnut peel, by batch fermentation under the condition of 30°C, with walnut peel as fermentation raw materials, and respectively choose F/M(vs/vs)=0.20, 0.15, the effect of food-microorganism (F/M) ratio on the gas properties was studied in biogas fermentation with walnut peel. The experimental results showed that in the fermentation with walnut peel as raw materials, the potential of TS and VS, the total volume and the time reaching to 80% gas production volume of the time of experimental group F/M(vs/vs)=0.20 were respectively 202ml/gTS, 226ml/gVS, 2840ml, 19d. However, the values of experimental group F/M(vs/vs)=0.15 were respectively 152ml/gTS, 170ml/gVS, 2140ml, 24d. Therefore, food-microorganism (F/M) ratio has a great influence on batch biogas fermentation with walnut peel as the fermentation raw material.
