The influence of ultrasonic pretreatment with specific energy input ranging from 25 to 550 kJ/kg volatile solids on the mixture of Sida hermaphrodita (L.) Rusby mixed with cattle manure disintegration and subsequent anaerobic digestion was assessed. The pretreatment process led to significant increase in the biomass solubility by 21.9% as chemical oxygen demand and enhanced biogas yield by 157% (567.1 L biogas/kg volatile solids) when the specific energy input was from 200 to 550 kJ/kg. However, only pretreatments where ultrasound was applied at 25–50 kJ/kg led to positive net energy gain, indicating that the biomass processing with this method does not always compensate the energy consumption for irradiation.

超声预处理增强两性map厌氧消化的评价

评估了超声能量输入比能量输入范围为25至550 kJ / kg挥发性固体的超声波预处理对Sida hermaphrodita（L.）Rusby与牛粪便分解和随后的厌氧消化混合的混合物的影响。当比能量输入为200至550 kJ / kg时，预处理过程导致化学需氧量使生物量溶解度显着提高21.9％，沼气产量提高157％（567.1 L沼气/ kg挥发性固体）。但是，只有以25-50 kJ / kg的超声波进行预处理才能获得正的净能量增加，这表明采用这种方法进行生物量处理并不能总是补偿辐照的能量消耗。
