沼气发酵料液中的总固体含量在20%以上者称为干发酵。与稀发酵相比,其优点是节约用水,产气周期长,不需日常的繁琐管理,池容产气率高,能积造较多的固体肥料。这项技术适宜在施用固体肥料和较干旱的地区推广。具体操作方法如下: 将秸秆或杂草等铡短为10—15公分,与粪便适当搭配后进行堆沤,然后加部分接种物拌匀,再从活动盖口入池。当加料到一定
Biogas fermentation feed liquid total solids content of more than 20% known as dry fermentation. Compared with dilute fermentation, the advantage is to save water, gas production cycle is long, without the cumbersome management of daily, high capacity gas production capacity, can build more solid fertilizer. This technology is suitable for the application of solid fertilizers and drier areas. Specific methods of operation are as follows: the stalks or weeds and other short 为 10-15 cm, with the stool with the appropriate stack after 沤, and then add some inoculum mix well, and then into the pool from the activities cover. When feeding to certain
