摘　　要：秸秆生物气化工程生产沼气是处理和利用秸秆的行之有效的方法,既防止了废弃秸秆污染和影响周边环境的问题,又解决了农村清洁能源短缺的难题。为此,研究了秸秆沼气工程的工艺方法及湿法发酵工艺参数的优化,为沼气规模化生产提供技术支撑和参考。研究表明:干物质(TS)浓度为8%、发酵温度为35℃、厌氧发酵周期35天,容积产气率最高可达76m3/(m3·d)。Straw gasification project production for biogas is the most effective methods to the processing and utilization of straw.This prevents the pollution of waste straw and affects the surrounding environment,and solves the problem of shortage of clean energy in rural areas.This paper studies the straw biogas engineering process method and wet fermentation process parameters optimization.Provide technical support and reference for large-scale biogas production.Research showed that dry matter TS concentration was 8%,fermentation temperature of 35 ℃,anaerobic fermentation cycle is 35 days,produce gas volume rate of up to 76m^3/（m^3· d）.
