Discussion on Integrated Utilization Technology of Rural Breeding Waste

摘要

Breeding contaminant is one of the important pollution sources of the rural ecological environment. It is an effective way to control environmental pollution that the solid waste and wastewater generated in captive breeding is used as resource. Propose a circulation agriculture model with "planting-breeding-biogas-fertilizer" combined organically. This model was applied in a farm in Jinniu town, Daye city, Hubei province. Through the follow-up survey and data analysis of the production on the farm, the results showed that the economic benefits not only was significant but also solved the pollution of the breeding contaminant completely. It actually accomplished "zero emissions". It proved that this model was suitable for small and medium-scale farms. It could provide reference for development pattern of ecological agriculture development in China.
