Method and device for recycling edible mushroom residues

Abstract

The invention relates to a method and device for recycling edible mushroom residues. The method mainly comprises the steps of placing waste mushroom residues and maize straws or excrements from a cattle farm into an anaerobic reactor for united fermentation to produce biogas, and covering a red-mud plastic head cover on the anaerobic reactor, wherein an inclined stirrer is arranged and is beneficial to feeding / discharging of mushroom residue raw materials and avoidance of crusting. The produced biogas is used for power generation and agriculture, biogas residues are used for manufacturing organic fertilizers, biogas slurry is prepared into foliar fertilizer for fruits or vegetables, and thus, new energy sources, namely the biogas and the organic fertilizers, are obtained while the mushroom residues are treated. The method and the device in the invention are mainly used in major edible mushroom producing areas, a solar-panel greenhouse and a solar heat supply device are assorted for the device, a composite microbial inoculum is assorted for the method, and the anaerobic reactor can be normally used all the year round.

Description

technical field [0001] The invention relates to a treatment method and device for resource utilization of edible fungus residues, which can simultaneously solve the problems of resource waste and environmental pollution of discarded mushroom residues, and belongs to the field of agricultural technology. Background technique [0002] At present, my country has become the world's largest producer of edible fungi. In 2009, the total output of edible fungi in the country reached 2.02×10 7 t, accounting for more than 70% of the world's total output, the total output of edible fungi in Shandong Province reached 2.06 million tons, accounting for 10.2% of the national total output of edible fungi. With the vigorous development of the edible fungi industry, a large number of edible fungus residues are produced every year. According to the average biological efficiency of edible fungi of 40%, the total output of edible fungi residues in China in 2009 is about 5.05×10 7 t, the total a...

AI Technical Summary

Problems solved by technology

[0007] Due to the characteristics of the edible fungus residue material, if the commonly used anaerobic reactor (such as an ordinary fully mixed anaerobic reactor) or a hydraulic household biogas digester (10-30m 3 ) and other anaerobic digestion devices for anaerobic fermentation, there are problems such as difficulty in feeding, easy crusting during anaerobic fermentation, and difficulty in discharging after anaerobic fermentation

There is no report on a new anaerobic reactor device suitable for the anaerobic fermentation of edible fungus residues to produce biogas, which can facilitate the feeding and discharging of materials, prevent crusting, and ensure normal operation in winter.
