Rural biological waste carbon-bottom dual pit and composting treatment method

Abstract

The invention provides a rural biological waste carbon-bottom dual pit and a composting treatment method. The carbon-bottom dual pit is characterized by being a deep pit excavated below a ground surface; a carbon bottom is arranged at the bottom of the deep pit; the carbon bottom is prepared by mixing 35 to 45 percent of biomass carbon, 20 to 30 percent of lime, 20 to 25 percent of cement and 5 to 10 percent of wood tar oil to form the pit bottom, and is compacted; a partition plate is arranged in the deep pit, and perpendicularly divides the deep pit into at least two pits; one deep pit is excavated at a low-lying position, or multiple deep pits are excavated in a high-to-low flowing direction; the carbon bottom is arranged at the bottom of each deep pit; solid-liquid wastes fed into the deep pit comprise biological wastes, animal manure and the like; after being filled with the wastes, the first deep pit is covered with a wood board cover for composting, and then the second deep pit starts to be used; 1 to 2 percent of saccharomycetes and 1 to 2 percent of malt acid-producing bacteria are added into the deep pits to accelerate composting; the wastes are dug out and returned to fields, are used as a special fertilizer and can be recycled; the biological wastes are composted, so that the problem of accumulation of the rural biological wastes is solved; the countryside ecological environment is improved; the living quality and the health of countryside inhabitants are improved.

Description

technical field [0001] The invention belongs to the comprehensive treatment of rural biological waste, and relates to a systematic solution to the low-cost treatment and short-distance utilization of rural waste, in particular to a method for treating rural domestic waste with double charcoal bottom pits and decomposing. Background technique [0002] The planning and construction of basic equipment in rural areas is relatively backward, and the management is relatively lacking. In addition, rural villages are scattered, resulting in the disorderly stacking and unmanagement of rural domestic waste for a long time. Rural domestic waste is generally dumped into small ponds or ditches, Simply buried, many rural biological wastes have not been effectively treated. After waiting for a period of time to decompose, farmers will use them as natural fertilizers in rice fields, but the organic matter and harmful substances in the waste will invade the water body and seriously pollute th...

AI Technical Summary

Problems solved by technology

The size of the villages varies, the distances between the residents in the villages are short and far, the operating cost of environmental protection facilities is high, and a large amount of other domestic waste of the villagers continues to accumulate, and the modern rural domestic waste treatment equipment is relatively scarce, and the funds are insufficient. Both lack funds for environmental investment, and the main equipment for waste treatment is relatively backward. Disposing of rural domestic waste consumes more manpower and financial resources, and the benefits generated are not obvious, resulting in insufficient facilities for the rural public environment.

[0004] At present, the technologies for harmless, reduction and recycling of garbage mainly include sanitary landfill, composting, and incineration, which seriously damage the quality of life and health of village residents. How to properly dispose of biological waste and recycle it Utilization, local utilization, has become a major issue in the development of rural society
