[0038] The method for rapidly reducing the moisture content in livestock and poultry excrement and urine used in the pretreatment process of organic fertilizer production comprises the following steps:
[0039] (1) Establish a treatment platform locally on the farm; the treatment platform is preferably a fermentation tank, its main function is fermentation, so that the water can be evaporated by fermentation and temperature rise, and it can be set lower than the ground in specific settings (digging pits on the ground), It can also be set higher than the ground (build a pool on the ground), without affecting the use effect, and to a certain extent, it can realize the immediate treatment of livestock and poultry excrement and urine, which greatly saves transportation costs;
[0040] (2) Prepare fermentation bedding, the raw materials of which include at least one of sawdust, rice husk, straw, fungus residue or dry cow dung after dry-wet separation, and lay the fermentation beddin...
