Study on the Characteristics of the Aquatic Vegetables Waste Fermentation to Biogas

Abstract:

Biogas production efficiencies from sole aquatic vegetables waste and plus with straw were investigated in this research. The results as flowns:The biogas production of 3375 ml with 62% CH₄ content was achieved when the ratio of the aquatic vegetables waste to the straw was 15:35 (g/g), which is much higher than the control using aquatic vegetables waste or straw as sole raw fermentation material to the extent of 15.85%-37.72%. And the volatile solids (VS) and total solids (TS) drastically change also be coincided with the biogas production. Which pyruvic acid, the acetic acid and citric acid content lower than that of control (the aquatic vegetables waste, the aquatic vegetables waste and the straw at ratio of 25:25 (g/g), the straw) 27.32%-44.35%, 37.77%-57.52%, 30.78%-46.52% respectely. The results implied that with certain proportions, aquatic vegetables waste can promote the biogas generated form straw fermentation.
