Livestock and poultry manure fermentation treatment method

Abstract

A livestock and poultry manure fermentation treatment method is disclosed. Livestock and poultry manure fermentation treatment equipment composed of a fermentation roller, a supporting device, a drive unit, a feeding and discharging device, a heating and stirring device and a ventilation unit is adopted. Through a feed screw conveyer inside the feeding and discharging device, fresh livestock and poultry manure which needs to be treated is conveyed into the fermentation roller; through rotating of the fermentation roller, ripened materials containing high-temperature fermentation strains are mixed in proportion; the product then undergoes continuous stirring, heating and dehydration, etc., and rationed oxygen supply at fixed time cooperates; and finally, completely fermented ripened materials are sent out, and potassium, phosphor or beneficial trace elements are added so as to form an organic compound fertilizer. By the method, manure can reach the most efficient fermentation temperature and water content. In addition, with rationed oxygen supply at fixed time, fermentation speed and fermentation effect are greatly improved. By adding potassium, phosphor or beneficial trace elements into the completely ripened livestock and poultry manure, utilization value of livestock and poultry manure is raised.

Description

technical field [0001] The invention relates to a feces fermentation treatment method, in particular to a livestock and poultry manure fermentation treatment method suitable for treating livestock and poultry manure in the breeding industry. Background technique [0002] In the livestock and poultry breeding industry, most of the livestock and poultry manure are treated by traditional simple methods, such as manual stacking and fermentation, manual overturning, or cheap sales, direct return to the field, or even discharge into rivers, causing serious environmental pollution. Due to the lack of scientific and effective treatment methods, at present, the livestock and poultry manure in the farms has not been treated effectively in a timely manner, causing environmental pollution, and the air is foul and unpleasant, and it is very difficult to deal with. However, with the enhancement of people's awareness of environmental protection, the problem of dealing with livestock and po...
