在试验条件下 ,采用单相厌氧消化系统对浸泡预处理的秸秆进行消化试验 ,研究了反应过程中 ,VFA、PH、COD及产气量的变化规律。试验结果表明当TS =4 1.8%时 ,浸泡时间不同 ,产酸峰值来临期基本相同 ,而浸泡 15天秸秆平均产气量为 71.4ml/d ,COD去除率达 6 1.3% ,具有较好的降解效果。
Abstract：Marinated straw is digested by using single-phase system in lab.During the reaction,the rules of para meters like VFA,PH,COD and biogas production are studied .When TS is 41.8%,the result shows that the peak value time is sameness, though the time of marinating pretreatment is different. The biogas production of 15 days for pretreatment is as 4.3 times as dry straw's, and the reduction of COD is 61.3%.
