Abstract

The invention discloses an excrement residue sterilization and deodorization method. The method comprises the following steps: collection, preliminary deodorization, an anaerobic reaction stage, an aerobic reaction stage, microwave treatment and filter pressing treatment. The method has the beneficial effects that (1) a deodorant, a microbial decomposition agent, microwave sterilization and plate-and-frame filter pressing are combined for treatment, synergistic interaction is achieved, and the excrement residues are effectively deodorized; (2) the microbial decomposition agent is used, so thatthe fermentation time is shortened compared with the existing composting treatment means; (3) through microwave treatment, the purpose of killing cells is achieved, and then sterilization and deodorization are performed; and (4) the filter pressing pressure is large, and the filter pressing period is short.

Description

technical field [0001] The invention relates to the technical field of excrement treatment, in particular to a method for sterilizing and deodorizing excreta. Background technique [0002] In recent years, with the adjustment of agricultural structure and the promotion of agricultural industrialization, the livestock and poultry breeding industry has developed rapidly towards large-scale and intensive development. However, due to unreasonable manure treatment technology, a large amount of manure is discharged without treatment, which destroys the circulation function of the original agricultural ecosystem and causes serious pollution problems. [0003] At present, the commonly used farming manure treatment methods include: drying method, incineration method, mechanical dehydration method, composting fermentation method, etc., but there are the following defects: the treatment time is long, the treatment process is simple, and various germs and stench in the manure residue ca...
