Abstract

The invention discloses a cow dung composting system. The system comprises a cow breeding area, a planting area, a composting area and a circulating pipeline, at least two composting units are arranged in the composting area, humus discharged by the composting units is discharged to the planting area, the circulating pipeline comprises a heat source section, a heat exchange section and a backflowsection, heat source sections are arranged in all the composting units, the heat source sections in every two adjacent composting units are communicated with each other, the heat source section in atleast one composting unit conveys a heat source medium outwards, the heat source section in at least one composting unit receives an external reflux cold source medium, the heat exchange section is arranged in the cattle breeding area and is connected with a heat source section for conveying a heat source medium outwards, the backflow section is arranged in the planting area, the input end of thebackflow section is connected with the heat exchange section, and the output end of the backflow section is connected with the input ends of all the heat source sections in an openable and closable mode. According to the cow dung composting system, the capacity of cow dung can be used for multiple times, and the situation that a large number of microorganisms die due to the too high temperature ofcow dung in the composting process can be avoided.

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...
