Bio-organic fertilizer and production method thereof

Abstract

The invention discloses bio-organic fertilizer. Through fermentation, the bio-organic fertilizer is prepared from 6-26wt% of filter mud produced by a sugar refinery, 55-75wt% of bagasse ash and 10-30wt% of ethanol concentrate. The production method comprises the following steps of 1, carrying out mixing stacking on filter mud produced by a sugar refinery, bagasse ash and ethanol concentrate, 2, removing moisture by filtration, 3, stacking the raw material mixture in a strip-shaped stack way, adding bifidobacterium, lactic acid bacteria, bacillus, saccharomycetes, actinomycetes and acetic bacteria into the stacked mixture, and carrying out fermentation, 4, keeping the primary fermented stack temperature above 60 DEG C and keeping material moisture content in a range of 40-45%, 5, increasing the height of the primary fermented stack, and carrying out secondary fermentation for aging until material moisture content is in a range of 30-35%, 6, adding the aged material into organic raw materials of N, P and K and carrying out mixing and 7, packaging the mixture to obtain the product. The bio-organic fertilizer has good fertilizer efficiency and is conducive to absorption by crops. The production method utilizes simple production equipment, has simple production processes and can be operated easily. The production method reduces a cost and has high income.

Description

technical field

[0001] The invention relates to a crop bio-fertilizer and a production method thereof, in particular to a method for producing a bio-organic fertilizer by using sugar factory filter mud, bagasse ash and alcohol concentrate. Background technique

[0002] In the production process of my country's sugar industry, it is inevitable to produce a huge amount of waste gas pollutants such as alcohol waste liquid, sugar factory filter mud, alcohol waste liquid, boiler ash water and cane pith every year. Among them, except for a small amount of sugarcane pith used as raw materials for papermaking and other used as boiler fuel, the remaining wastes have not been effectively utilized, and only some incomplete environmental protection treatments have been done, and they are directly discharged. Sugar companies have spent a huge amount of environmental protection costs. Produce any economic benefits, and can only treat about 1 / 3 of the existing exhaust pollutants. Almost e...
