1.秸秆粉碎 即将秸秆切短切碎(或粉碎)。有机物质是沼气发酵的主要营养物质,秸秆之类的有机物除矿物油和木质素外都能被微生物分解发酵产生沼气,但秸秆类是较难分解产气的,为使这类有机物易于分解,必须和沼气微生物有较大的接触面。如将秸秆粉碎入池是最理想的,如秸秆粉碎难以做到,也可将秸秆尽量切短切碎,至少切成10厘米左右的小段,以增加原料和微生物的接触面,同时发酵后施于农田也容易撒开。 2.堆沤处理 将切碎的秸秆散铺地面,泼洒沼气池中的沼液或阴沟中的污泥污水,进行翻拌,使秸秆全部
1. straw crush short straw chopped (or crushed). Organic matter is the main nutrient of biogas fermentation. Organics such as stalks can be biogas decomposed and fermented by microorganisms except for mineral oil and lignin. However, straw is more difficult to decompose gas, in order to make these organic compounds easy to decompose, Biogas must have a larger contact surface. If the straw crushed into the pool is the best, such as straw crushing difficult to do, but also the straw chopped as short as possible, at least cut into small pieces of about 10 cm in order to increase the contact surface of raw materials and microorganisms, while Shi Shi Shi In the farmland is also easy to spread. 2. Heap 沤 treatment The shredded straw scattered on the ground, spilled digester biogas slurry or sewer sewage sludge, for mixing, the straw all
