白腐菌对玉米秸秆产沼气的试验研究

目的]研究白腐菌对玉米秸秆产沼气效果的影响。方法]采用4株不同的白腐菌在相同的条件下对玉米秸秆进行预处理,预处理后的原料再进行干发酵制取沼气的试验研究。结果]结果表明:原料以Cv处理后沼气产量最高,纤维素的降解效果最好,其总产气量是42 187 ml(按60 d计),产气率为703.1 ml/d,纤维素降解率为54.2%。结论]木质纤维素降解率越高,沼气产量也越多。

Experimental Study on the Effects of White-rot Fungus on the Production Ability of Methane with Corn Straw Stalk

Objective] The aim of the research was to study the effects of white-rot fungus on the production ability of methane with corn straw stalk.Method] Four different white-rot fungi was used to carry on the pretreatment under the same condition,after pretreatment raw material in the fermentation system was used to take methane.Result] The results indicated that,raw material after Cv processing had highest methane output,the cellulose degeneration effect was best,total output spirit was 42 187 ml(according to 60 days ideas),gas production rate was 703.1 ml/d,the cellulose degeneration rate was 54.2%.Conclusion] The higher the lignocellulose degeneration ratio was,the more the methane output.
