NOVELTY - The integrated system comprises a device (1) for composting and fermenting livestock or poultry, a power generation device (2) for supplying electricity and heat by combustion of agricultural straws, a device for mixing a product of the composting device and a straw burned product, a device (3) for granulating the product of the mixing device, and a drying device (4) for drying the product of the granulating device. The power generation device provides a hot blast for drying the drying device.    USE - The integrated system is useful for producing organic-inorganic compound fertilizer using agricultural wastes.    ADVANTAGE - The integrated system is capable of easily, rapidly and economically producing the organic-inorganic compound fertilizer in an environmentally friendly manner with high efficiency, improved quality and reduced power consumption, and has simple structure.    DETAILED DESCRIPTION - The integrated system comprises a device (1) for composting and fermenting livestock or poultry, a power generation device (2) for supplying electricity and heat by combustion of agricultural straws, a device for mixing a product of the composting device and a straw burned product, a device (3) for granulating the product of the mixing device, and a device (4) for drying the product of the granulating device. The power generation device provides a hot blast for drying the drying device, and comprises a biomass fuel boiler and a steam turbine generator set. The biomass fuel boiler forms heat and steam, and is connected with a dust collector. The steam turbine generator set is driven to generate the electricity using the steam. The mixing device, the granulating device and the drying device are integrated. An INDEPENDENT CLAIM is included for an integrated method for producing organic-inorganic compound fertilizer using agricultural wastes.
