禽畜干清粪工艺产生鲜粪的厌氧消化处理技术探讨

摘要

Through the analysis of the characteristics of different kinds of livestock fresh feces and combined with the characteristics of horizontal and vertical dry anaerobic digestion process,the suitable digestion process was put forward that horizontal dry anaerobic digestion was appropriate for cattle,sheep,horse,and rabbit fresh feces,vertical dry anaerobic digestion was suitable for pig,chicken,and rabbit fresh feces.Additionally,the biogas production decided the higher rank in this order:pig fresh feces ＞ chicken fresh feces ＞ rabbit fresh feces ＞ horse and cattle fresh feces ＞ sheep fresh feces.%通过分析各类禽畜鲜粪特征,结合卧式和立式干法厌氧消化技术特点,提出了牛、羊、马鲜粪适宜采用卧式干法厌氧消化技术,鸡、猪鲜粪适宜采用立式干法厌氧消化技术,兔鲜粪既可采用卧式干法厌氧消化技术,也可采用立式于法厌氧消化技术,明确了各类禽畜鲜粪沼气产量大小:猪粪＞鸡粪＞兔粪＞马粪和牛粪＞羊粪.
