Abstract

The invention discloses an ecological cow pasturage waste disposing system and disposing method, which is characterized by the following: adopting waste disposing and artificial cattle manure ruminant disposing method of multi-AO method [(AOA)n] to dispose pasturage waste synthetically; removing most of pollutant for waste water in the disposal system; disposing nitrogen and phosphor material with cattle manure; adopting fresh cattle manure as raw material to cultivate bacterium agent; reducing moisture percentage to 20 percent more or less through aerobic fermentation; transmitting cattle manure into organic fertilizer of national standard.

Description

Technical field [0001] The invention relates to a processing system and a processing method for ranch waste treatment, in particular to a dairy cattle ranch waste processing system and a processing method. Background technique [0002] With the rapid economic development and the continuous improvement of residents’ living standards, people’s dietary structure is also gradually changing, especially the demand for milk products and other livestock and poultry products is also increasing. High-quality livestock and poultry products have become the current Shanghai An important part of the diet of city residents. With the continuous expansion and extension of the scale of cities, livestock farms are also transforming into urban aquaculture. Its impact on the surrounding environmental protection is increasingly being valued by all aspects of society. The improvement of the ranch environment, especially the proper disposal of ranch waste, has become a city. The problem faced by the typ...
