A kind of processing method of cow dung

Abstract

The invention provides a cow dung handling method. The cow dung handling method comprises the steps of cow bed building, bedding spreading, cow dung collecting and cow dung burning. Cow dung ash obtained after cow dung burning can return back to the farmland or serve as dry ash for gasket bedding, and cow dung harmless recycling utilization can be achieved. The gasket bedding is made of corncob powder and the dry ash, corncobs are cob cores obtained after corn threshing, after the corncobs are pulverized, the corncob powder has high adsorbability, can absorb liquid of which the weight is fourtime the weight of the corncob powder, and can serve as bedding of a cow bed, cow bed drying is facilitated, and cow dung can be conveniently removed. The cow dung contains a lot of indigested main cellulose, lignin and the like, is loose in structure and is similar to plant ash after being burned into ash. The plant ash and the cow dung have the quite high pathogenic bacteria and virus killing effect, are similar to common strong disinfectant caustic soda in effect, have the characteristics of being high in disinfecting action, free of side effect and irritation and the like, and are used forpreparing the cow bed gasket bedding, and drying and bacterium inhibition of the cow bed are facilitated.

Description

technical field [0001] The invention relates to the technical field of cow dung treatment, in particular to a method for treating cow dung. Background technique [0002] With the strong market demand for beef and the need to speed up the economic development of poor areas, in recent years, the national policy has been tilted towards the "three rural areas" and increased support for the breeding industry. Driven by policy support from 2015 to 2016, all regions Rural households in mountainous areas with resource advantages have high enthusiasm for beef cattle breeding, and the development momentum is strong. It has become one of the most promising rural agricultural pillar industries. In most rural areas, beef cattle breeding is an important source of family income. However, with the increasing scale of breeding, the accompanying problem of cow dung disposal has plagued farmers. A 450kg cow can excrete about 25kg of feces per day on average, and can excrete as much as 9000kg ...

AI Technical Summary

Problems solved by technology

Anaerobic fermentation of cow dung to produce biogas requires high technical requirements and high equipment operating costs. In some mountainous villages where cattle are concentrated, the mode of raising cattle is mainly family-based. Due to financial constraints, there are basically no cow dung treatment facilities.

Composting to produce organic fertilizer and returning it to the field through fermentation is the best way to deal with cow dung in rural areas. However, due to too much cow dung, the carrying capacity of the field is limited, and too much cow dung is piled up everywhere, especially in summer. The air is soaring, and mosquitoes and flies breed, which has become an important source of pollution in the rural environment

Because cow dung contains parasite eggs and pathogenic microorganisms, after the rain washes away, it also causes serious pollution to the surrounding surface water and groundwater. In addition, raw cow dung goes directly to the ground, causing root and seedling burn
