沼气池建好后,接着要做的事情就是向池内投产气所需的原料。 沼气原料有两大类,即秸秆杂草和人畜粪便。秸秆杂草主要成份是纤维素,分子链较长,分解速度慢;粪便原料属颗粒性物质,残存一定量易分解的糖、脂、蛋白质等物质,分解速度快,产气周期短。过去农村多数采用秸秆杂草发酵,由于粪便不足,产气发酵情况差,根据近年实践看,秸秆作原料投料换料较难,在无机械情况下换料时 After the biogas digester is built, the next thing to do is to feed the raw materials needed for gas production to the pool. Biogas feedstock has two broad categories, namely, straw weeds and livestock and poultry manure. Straw weed is the main component of cellulose, the molecular chain is longer, the decomposition rate is slow; fecal material is a particulate material, a certain amount of residual sugar, fat, protein and other substances remain, decomposition speed, gas production cycle is short. In the past most of the rural straw weeds fermentation, due to inadequate manure, gas production is poor, according to recent practice, straw as a raw material feeding refueling more difficult in the absence of mechanical refueling
