Method for producing organic fertilizer by fermentation method

Abstract

The invention discloses a method for producing an organic fertilizer by a fermentation method. The organic fertilizer is produced through the following steps: adding an organic material ageing reagent in the prior art into livestock manure serving as a raw material and mushroom slag, unite bran and humic acid serving as auxiliaries, evenly stirring, ventilating through artificial air blast for pilling fermentation and post-ripening, and packaging a finished product. The method is characterized in that the fermentation is slope type fermentation which is as follows: a fermentation groove is built on a slope, the fermentation groove with multiple slope staggered layers is built by utilizing hillside terrain, a 'cliff' formed by slope staggered layers which are adjacent is used as a ventilation channel, and an air blower is installed outside for air blowing oxygen, so as to form a static aeration system. According to the invention, the livestock manure is used as the raw material, and the organic fertilizer is produced by using the fermentation method, thus the method disclosed by the invention has the advantages that the investment is saved, the fermentation operation is convenient,sterilization and deodorization are complete, no secondary pollution is generated, humification and harmless degrees are high, the product quality is good, the production efficiency is high, and the popularization is easy.

Description

1. Technical field [0001] The invention relates to a method for producing organic fertilizer, in particular to a method for producing organic fertilizer by using livestock and poultry manure as raw material and adopting compost fermentation. 2. Background technology [0002] In recent years, my country's aquaculture industry has developed rapidly, and is developing in the direction of specialization, scale and intensification. At the same time, more and more wastes are discharged from the breeding industry. Livestock manure contains a large amount of organic pollutants, and COD alone reaches 71.18 million tons, far exceeding the sum of COD of industrial and domestic sewage pollutants. At present, due to financial and technical reasons, the rate of harmless, resourceful and commercial treatment of feces is less than 5%. Large-scale livestock and poultry farming has become the main source of environmental pollution in rural areas of our country, causing huge pressure on the ec...

AI Technical Summary

Problems solved by technology

However, this method has the following defects: first, it needs to invest in the construction of ventilation pipes to ventilate the stockpile; second, when loading and unloading materials, mechanical equipment such as forklifts often block or even damage the ventilation pipes, resulting in poor ventilation, which not only prolongs The fermentation time also affects the quality of organic fertilizer products, and it takes a lot of manpower to clean and repair the ventilation pipes

The defect of this method is that the investment is large, the production cost is high, and it is really difficult to popularize
