为了使新建成的沼气池产气快、产气好,初次装料时应注意如下事项:1、第一次投料时,要把占发酵料液10~30%的优良沼气菌种接种物(如沼气池发酵液、粪坑底污泥)和发酵原料均匀混合,一同加入池内。2、第一次投料时,要按照适宜的碳氮比(25:1)和料液浓度(6~10%),合理掺配原料入池。首次投料以人、畜禽粪便为主,选择有机营养适合的牛粪、猪粪、羊粪掺配做启动的发酵原料
In order to make the newly built biogas digester gas fast, good gas production, the first charge should pay attention to the following matters: 1, the first feed, it is necessary to account for 10 to 30% of the fermentation feed liquid excellent biogas inoculum Such as digester fermentation broth, scum pit bottom sludge) and the fermentation raw materials are uniformly mixed, together with the pool. 2, The first feeding, according to the appropriate carbon and nitrogen ratio (25: 1) and feed concentration (6 ~ 10%), a reasonable mix of raw materials into the pool. For the first time to feed the man, livestock and poultry manure, choose organic nutrition suitable cow dung, pig manure, sheep dung mixed start to do with the fermentation of raw materials
