Abstract

The invention relates to a bio-fertilizer produced by fermenting steel slag, vinegar residue and weathered coal through microbes and a preparation method thereof. The bio-fertilizer comprises the following components in percentage by weight: 15 to 20 percent of steel slag, 5 to 73 percent of vinegar residue, 10 to 15 percent of weathered coal and 0.05 to 0.1 percent of microbes. The preparation method comprises the following steps: selecting the microbes; activating the microbes; performing first-stage and second-stage rocker expansion; mixing; fermenting; turning a pile; obtaining finished products; drying at low temperature; detecting; and metering and packaging. The steel slag, the vinegar residue and the weathered coal are subjected to high temperature fermentation by utilizing the microbes; metallic oxides in the steel slag and organic acid in the vinegar residual undergo neutralization reaction to generate an organic complex under the action of the weathered coal and the synergy of the microbes so as to improve the effectiveness of the fertilizer; and the method can be promoted and applied to innocent treatment for various industrial and agricultural wastes such as flyash in a power plant, vinasse in a winery, decoction dreg in a pharmaceutical factory, urban garbage and the like, can change the wastes into treasure, and protects the environment simultaneously.

Description

technical field [0001] The invention belongs to a biological fertilizer, in particular to a biological fertilizer produced by using microorganisms to ferment steel slag, vinegar grains and weathered coal and a preparation method thereof. Background technique [0002] Steel slag is waste that has been treated at 1500-1700°C in iron and steel production. The quantity is huge. In terms of recycling, there are many building materials and road construction, which have relatively large limitations. After in-depth research by the company's scientific and technical personnel, it is found that steel slag is mainly composed of calcium, iron, silicon, magnesium and a small amount of oxides such as aluminum, manganese, and phosphorus. The main minerals are solid solutions formed by tricalcium silicate, dicalcium silicate, calcium magnesium olivine, calcium magnesium rhodite, calcium aluminate ferrite and oxides of silicon, magnesium, iron, manganese and phosphorus. free calcium oxide a...
