Method for integrated utilization of agricultural waste resources

Abstract

The invention discloses a method for integrated utilization of agricultural waste resources. The method comprises the first step of performing vacuum high-temperature aerobic fermentation on agricultural waste; the second step of breeding earthworms by utilizing a product obtained after the high-temperature aerobic fermentation; and the third step of performing fermentation to generate biogas. The development and utilization of livestock and poultry excrement and crop straw are achieved, the treated agricultural waste is all converted into high protein feed (or food and medicines), pollution-free organic fertilizer and biogas energy, pollutants are free of emission, the varieties of agricultural products are increased, nuisanceless agricultural production materials and clean bio-energy are produced, the rural environment is protected, and the social benefit, economic benefit and ecological benefit are very remarkable. An annular kiln type biogas dry type fermentation device and an aerobic fermentation device which are researched and developed by the inventor are utilized, and the effects of the method are increased.

Benefits of technology

This technology allows for better use of animal waste by converting it into higher quality nutrients that can be used without causing environmental concerns or harming crops grown on them.

Problems solved by technology

This technical issue addressed in this patents relates to the lack of efficient methods for disposal of pesky waste generated from domesticated crops such as corn fields during landfill operations without leaving behind harmful substances like ammonium salts (BAS) and heavy metals on soil surfaces. Existing techniques involve either airborne decomposition or wet digestion followed by ground settling processes requiring long periods before effective remotely controlled combustion systems could operate effectively overnight. Additionally, current practices require excessive human resources and result in negative impacts upon public health and safety concerns.
