Cutting-type aeration compost method

Abstract

The invention discloses a cutting-type aeration compost method. After a compost material is stacked to a certain height in an inner chamber, an aeration stirring device is turned on, a power mechanism drives an aeration pipe to perform transverse or vertical movement in the inner chamber, a whole compost cross section is cut along the transverse or vertical directions, at the same time, the aeration pipe enables autoroatation with 360 DEG, a blower is turned on, and air is dispersed from the aeration aperture for performing aeration on the compost. With the motion of the aeration pipe, the compost is continuously stirred by the aeration stirring device, the compost material is more uniform, good granular shape is formed, good porosity is effectively kept, air is directly introduced into the compost, oxygen utilization rate is greatly increased, compost heat is more uniform and penetrative, turning is not required during a composting process, aeration energy consumption, composting time, operation difficulty and operation cost are reduced, and the quality of an organic fertilizer is effectively provided. In addition, an aeration apparatus is not required for being arranged at the bottom of the equipment, and the phenomena of draining, obstruction and crushing damage of the aeration pipe at bottom cannot be generated.

Description

technical field [0001] The invention is used in the field of biological composting, and in particular relates to a cutting type aeration composting method. Background technique [0002] my country has become the world's largest producer of meat and eggs. In recent years, a large number of intensive livestock and poultry farms have sprung up in my country. According to incomplete statistics, the livestock and poultry breeding industry emits a large amount of pollutants. The annual production of livestock and poultry manure in the country is about 4.5 billion tons (about 50% comes from intensive livestock and poultry farms), which is 2.7 times that of industrial solid waste. The environmental pollution caused by the rapid development of livestock and poultry breeding industry has reached a very serious level. Livestock and poultry farms have become one of the main causes of rural non-point source pollution, which has brought great harm to the natural environment and residents...
