Abstract Water hyacinth is a deadly weed in an aquatic environment but a potential feedstock for the generation of renewable biogas through anaerobic digestion. Biochemical methane potential (BMP) was examined for fresh water hyacinth whole plant after microbial pretreatment to determine the ideal food to microorganism (F/M) ratio. The study revealed that after microbial pretreatment of water hyacinth the F/M ratio 1.5 showed the highest methane yield of 156 ± 19 mL CH4/g VS on the 20th day. It was observed that the microbial pretreated water hyacinth illustrated enhanced biogas production within a short time period when compared to the untreated water hyacinth. The ideal F/M ratio played a significant role alongwith the microbial pretreatment process to accelerate the hydrolysis period and increasing biogas generation.

微生物预处理后水葫芦的厌氧生物降解性测试以优化理想的 F/M 比

摘要 水葫芦是一种水生环境中的致命杂草，但它是通过厌氧消化产生可再生沼气的潜在原料。在微生物预处理后检查淡水风信子整株的生化甲烷潜力 (BMP)，以确定理想的食物与微生物 (F/M) 比。研究表明，水葫芦经过微生物预处理后，F/M 比为 1.5 的第 20 天甲烷产量最高，为 156 ± 19 mL CH4/g VS。据观察，与未经处理的水葫芦相比，经过微生物预处理的水葫芦在短时间内提高了沼气产量。理想的 F/M 比与微生物预处理过程一起对加速水解期和增加沼气产生起着重要作用。
