Field compost fermentation tank and using method

Abstract

The invention discloses a field compost fermentation tank and a using method, the field compost fermentation tank comprises a first fermentation tank, a second fermentation tank, a first fermentationtank material and a using method, the first fermentation tank is 3-6m long, 2-6m wide and 1.5-2m deep, the volume of the first fermentation tank is 10m < 3 >, the length, width and height are 6m, andthe maximum volume is 216m < 3 >; the first fermentation tank is provided with two material inlets; each material inlet is square, the side length of the material inlet is 0.5 m, a rectangular discharge port is formed in the bottom of the first fermentation tank, the length of the discharge port is 1-1.5 m, and the width of the discharge port is 0.6-1m. Through the design and application of the field organic fertilizer fermentation tank, the fermentation efficiency can be improved by adjusting indexes such as oxygen supply, temperature and moisture during material fermentation under the condition that various materials such as field crop straws, vegetable residues and livestock and poultry manure are fed, and the materials are utilized after reaching a completely decomposed state.

Description

technical field [0001] The invention belongs to the technical field of composting, and in particular relates to a field composting fermentation tank and a using method. Background technique [0002] Aerobic composting is a simple and efficient method for making organic fertilizers. Its basic principles are clear and its process is relatively mature. However, there are four problems in the traditional composting process and equipment: first, the phenomenon of anaerobic fermentation of the compost often occurs in traditional composting, resulting in the generation of a large amount of odor; This leads to incomplete fermentation of compost, and there is a risk of burning roots; third, the fermentation cycle of traditional compost generally takes several months, which is long, and the efficiency of organic fertilizer production is relatively low; fourth, traditional composting equipment is aimed at commercial organic fertilizers. Fertilizer production and use, lack of small pra...
