近年来,日本在沼气生产技术设施方面新研制出了一种新型的不稀释、高负荷发酵装置。这种沼气发酵装置的主要工作原理是首先把家畜的粪和尿进行分离,再把被分离出来的粪用榨汁机压榨,将榨得的汁液投放到沼气发酵池发酵产生气体。因为能够投入发酵池的少量的榨汁液(从粪便及沉淀渣中榨得的)中含有大量的容易分解的有机物质,故不需对发酵池加温以增加必要的气压,则可产得相当于发酵池同容积的三倍以上的气体(沼气)。又由于不用沼气给发酵池加温,因而在冬季所生产的 In recent years, Japan has newly developed a new type of undiluted and highly-loaded fermentation plant in the biogas production technology and facilities. The main working principle of this biogas fermentation device is to separate the livestock’s excrement and urine first and then squeeze the separated excrement with a squeezer to put the squeezed juice into the biogas fermentor for fermentation to produce gas. Because the small amount of squeezed juice (extracted from the faeces and sediments) that can be put into the fermentation tank contains a large amount of readily decomposable organic matter, it is not necessary to warm the fermentation tank to increase the necessary pressure to produce a comparable In the fermentation tank with more than three times the volume of gas (biogas). And because there is no biogas fermentation tank to warm, and thus produced in winter
