玉米秸秆直接经过预处理A(对照),玉米秸秆用复合菌剂绿秸灵预处理B,玉米秸秆用纤维素酶A和纤维素酶B混合预处理C,玉米秸秆和牛粪尿混合预处理D,4种不同预处理方式的玉米秸秆产沼气对比试验。结果表明:用复合菌剂处理过的玉米秸秆试验B,用纤维素酶处理过的玉米秸秆试验C和玉米秸秆与牛粪尿混合试验D,平均产气量均高于直接经过预处理的玉米秸秆对照试验A,分别提高了33.47﹪,35.76﹪,36.65﹪;处理D的秸秆产沼气比处理B和处理C的秸秆产沼气早2天,比处理A(对照)的纯秸秆产沼气早5天。
Corn stalks directly through the pretreatment A (control), corn stalks with compound straws Green straw spirit pretreatment B, corn stalks with cellulose A and C mixed pretreatment C, corn stalks and cattle manure mixed pretreatment D , Four different pretreatment corn stalk biogas production contrast test. The results showed that the corn stover B treated with the compound fungicide, the corn stalk C tested with cellulase and the corn mixed with cow dung urine D, the average gas production was higher than the corn stalk directly pretreated Control experiment A increased 33.47%, 35.76% and 36.65% respectively. The biogas production of straw for treatment D was two days earlier than the treatment for biogas production from straw for treatment B and treatment C, five days earlier than the treatment for biogas production from pure straw for treatment A (control) .
