Method of producing organic fertilizer by fermentation of poultry and animal faeces

Abstract

A process for preparing organic fertilizer from the dung of domestic animals and the droppings of fowls through proportioning mixing them with organic waste and assistant to obtain culture medium inoculating composite microbial seeds composed of aerobic, facultative and anaerobic bacteria, stacking, fermenting at 15-70 deg.C, granulating, and fermenting again. Its advantages are low cost and high bioactivity.

Description

technical field [0001] The invention belongs to a method for producing organic fertilizer by biological fermentation, in particular to a method for producing organic fertilizer by fermenting livestock and poultry manure. Background technique [0002] With the development of pollution-free, green and organic agriculture, the use of microorganisms to ferment organic materials and factory production of organic fertilizers have become a new trend. The market usage of granular organic fertilizers is increasing, but it is affected by the production process of organic fertilizer granulation. The production and quality of its products are difficult to guarantee. At present, the following two methods are generally used for organic fertilizer granulation: one is to ferment first and then granulate. If drying will increase the cost and cause damage to microbial strains, if not drying If it is dry, the drying of the product will become a problem; the second is t...

[0002] With the development of pollution-free, green and organic agriculture, the use of microorganisms to ferment organic materials and factory production of organic fertilizers have become a new trend. The market usage of granular organic fertilizers is increasing, but it is affected by the production process of organic fertilizer granulation. The production and quality of its products are difficult to guarantee. At present, the following two methods are generally used for organic fertilizer granulation: one is to ferment first and then granulate. If drying will increase the cost and cause damage to microbial strains, if not drying If it is dry, the drying of the product will become a problem; the second is to granulate first and then ferment. This process uses unfermented materials to granulate directly. Because the materials are generally viscous and have a strong odor, the operating environment is extremely poor.
