有着存储期的猪粪与米糠、尿素不同比例混合厌氧发酵试验研究

The Experimental Research on Anaerobic Fermentation of Pig Manure with Storage Duration, Rice Bran and Urea

为探索贮存期粪便发酵沼气产气量与米糠和尿素添加量之间的关系,确定促进沼气厌氧发酵的最佳添加量,以猪粪为发酵原料,研究在有着一定存储期条件下的猪粪同时添加不同量的米糠和尿素对厌氧发酵产沼气的影响,分析了厌氧发酵过程中产气速率、累积产气量及甲烷含量的变化,以确定添加米糠和尿素以提高猪粪产气量的可行性和科学性。

The relationship between addictive amount of rice bran and urea and biogas output by manure with storage duration was analyzed to determine the best addictive amount to accelerate anaerobic fermentation. With pig manure with storage duration as fermenting material, the effects of rice bran and urea with different addictive amount on anaerobic fermentation were studied, and biogas production rate, biogas accumulation and change of methane content were analyzed to determine feasibility and scientificity of adding rice bran and urea to increase biogas output of pig manure.
