    摘要:

    在（35±1）℃條件下，采用序批式厭氧消化工藝進行了L9（33）正交試驗，以生物炭添加量、生物炭粒徑和接種量為因素探索生物炭添加對雞糞厭氧消化產(chǎn)氣特性影響，得出了雞糞添加生物炭厭氧消化產(chǎn)氣的最佳工藝組合。結(jié)果表明，各因素對雞糞厭氧消化產(chǎn)沼氣特性的影響從大到小依次為：生物炭添加量（極顯著）、生物炭粒徑（不顯著）、接種量（不顯著）。最佳處理組合總固體產(chǎn)氣率為345.96mL/g，揮發(fā)性固體產(chǎn)氣率為420.62mL/g，比對照組提高了45.24%。生物炭粒徑對甲烷體積分?jǐn)?shù)有極顯著影響。

    Abstract:

    An L9（33） of orthogonal experiment on batch anaerobic digestions was conducted in order to investigate the effects to biogas production characteristics by adding biochar in anaerobic digestion of chicken manure under the mesospheric condition (35±1)℃. The effects of the three factors including biochar concentration, inoculums concentration and biochar thickness on biogas production characteristics were determined. The optimal combination of these three factors was achieved. The results showed that the factors affect biogas production from highest to lowest were biochar concentration (very significant), biochar thickness (not significant), and inoculums concentration (not significant). The effect of thickness of biochar to methane contents achieved a very significant level.
