摘　　要：取自云南红酒厂的酒精废醪液经固液分离后,在恒温30℃下,滤液分别采用批量发酵工艺和半连续工艺进行了厌氧发酵产沼气的实验。实验结果表明,发酵滞留时间为15d,原料产气率为0.23m3/kgCOD;24d后,批量发酵的产气量与COD降解间的关系为:245L/kgCODrem oved,COD降解率为85.24%;半连续发酵的产气量与COD降解间的关系为:285L/kgCODrem oved,COD降解率为69.79%.The experiment was carried in two identical fermentation systems at 30℃mesophilic temperature for treating wastewater that discharged from Yunnan red winery.The fermentation systems are batch fermentation and semi-continuous fermentation.The results showed that the rate of gas generation is 0.23m^3/kgCOD when hydraulic retention time（HRT） is 15 days.After 24 days,COD degradation rate is 85.24%,gas yield is 245L/kgCODremoved in batch fermentation system.Meanwhile COD degradation rate is 69.79%;gas yield is 285L/kgCODremoved in semi-continuous fermentation system.
