Description

Fermentation process of farm manure

technical field

Following this, the amount of pig manure is huge, and the excrement is harmful to the environment. pollution is becoming increasingly serious. The toxic and harmful substances in livestock and poultry manure are seriously beyond the capacity of the environment. If they are not treated harmlessly, it will not only cause groundwater pollution and microbial content exceeding the standard, but also pollute the air, making ammonia, sulfur dioxide and other harmful gases in the atmosphere At the same time, livestock and poultry manure will also cause soil environmental problems such as soil acidification and heavy metal residues.

At present, there are several methods for the treatment of aquaculture manure, such as anaerobic fermentation method (digester), composting method or direct application as fertilizer, but the existing treatment methods all have large investment, large land occupation, secondary pollution and technical problems.

Not only is the process control difficult, the process steps are cumbersome, and the treatment time is very long (15~ 60 days), it is difficult for general farmers to form a scale. On the other hand, cultured manure itself is a kind of good farmyard manure, and it is a high-quality organic fertilizer resource for fertilizing and improving the soil. However, if the manure is directly applied, it will inevitably have negative effects such as crop root damage, disease, and weed damage. .
