A cow dung composting system

Abstract

The invention discloses a cow dung composting system, which comprises a cow breeding area, a planting area, a composting area and a circulation pipeline; at least two composting units are arranged in the composting area, and the humus discharged from the composting unit is discharged to the planting area, and the circulation pipeline Including heat source section, heat exchange section and return section; all composting units are equipped with heat source sections, the heat source sections in two adjacent composting units are connected, and the heat source section in at least one composting unit transports the heat source medium outward, at least The heat source section in a composting unit receives the cold source medium that returns from the outside; the heat exchange section is set in the cattle breeding area and is connected to the heat source section that transports the heat source medium outward; the return section is set in the planting area, and the input end of the return section It is connected with the heat exchange section, and the output ends of the return section are openably and closably connected with the input ends of all heat source sections. The cow dung composting system can make multiple use of the ability in the cow dung, and can avoid the situation that a large number of microorganisms die due to the high temperature of the cow dung during the composting process.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a cow dung composting system. Background technique [0002] Cattle raising is a relatively promising industry. At present, the scale and intensification of cattle farms continue to increase, and the excrement produced by large cattle farms seriously pollutes the environment. With the further development of my country's cattle industry, the production of cattle dung and other breeding wastes has gradually increased, which has brought more severe environmental pollution problems. For this reason, cattle farms generally carry out secondary treatment on cow dung, such as biogas fermentation or composting, to reduce the pollution of cow dung to the environment and to facilitate the use of cow dung. [0003] Composting technology is one of the important means to realize the harmless treatment and resource utilization of livestock and poultry manure. It is in line with the developmen...
