The operation cost is low, and the environmental impact is little: solar energy is used as a heat source, a heat-preservation water tank and a circulating hot water pump are matched, and the internal temperature of the aerobic composting reactor is regulated and controlled in a hydrothermal mode, so that the energy consumption is greatly reduced; the percolate is collected, precipitated and filtered to be used as a main spraying water source, so that the pollution of the percolate to the surrounding environment is avoided.
3. The compost has no peculiar smell, and the environment of the plant area is good: each composting bin opening is provided with a plasma deodorizer 4, the concentration of ammonia gas, hydrogen sulfide and the like under the odor emission condition of the bin opening is monitored in real time, and the composting bin opening is automatically opened after the concentration is higher than a limit value, so that the good environment of a composting site is ensured.
4. The automation degree is high: the device does not need personnel to watch, regularly patrols and examines equipment and can guarantee normal operating.
