Example Embodiment

[0013] Example 1

[0014] The preparation method of biogas ammonium phosphate compound fertilizer includes the following production steps:

[0015] 1) Add 22kg of calcium-magnesium phosphate fertilizer to the inner cubic meters of the fermentation residue inside the biogas digester and stack it with the organic waste. The stacking method is one layer of organic waste and one layer of fermentation residue. The thickness of the residue layer is 50cm, the organic waste layer is 70cm, and the stacked shape is a truncated cone;

[0016] 2) In step 1), cover the truncated cone-shaped stack with a layer of soil, and pat it firmly. After 15-20d, the biogas rot phosphate fertilizer is obtained;

[0017] 3) During the first 5-7 days of fertilizer use, punch 5-7 holes downwards at different places on the top of the stack;

[0018] 4) After diluting 13kg of concentrated ammonia water, pour it into the compost from the hole in step 3), and then plug it with soil;

[0019] 5) Before using the fertili...

Abstract

The invention discloses a preparation method of a biogas fermentation ammonium phosphate compound fertilizer and relates to the technical field of preparation of fertilizers. The preparation method comprises the following steps: stacking fermentation residues in a biogas digester and organic waste to form the shape of a round table; and adding a calcium-magnesium phosphate fertilizer and concentrated ammonia water, drying and granulating. The preparation method provided by the invention has the beneficial effects that in the preparation method provided by the invention, the fertilizer prepared from the fermentation residues of biogas can not only turn the fermentation residues into treasure; and simultaneously, the prepared fertilizer has high content of nutrients in actual application, and the method is also simple in the actual production of the fertilizer.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a preparation method of marsh ammonium phosphate compound fertilizer. Background technique [0002] Biogas, as the name suggests, is the gas in the swamp. People often see that in swamps, sewers or cesspools, there are bubbles coming out. If we strike a match, it can be ignited. This is the naturally occurring methane. Biogas is a kind of combustible gas produced by the fermentation of microorganisms in the isolation of air and at a suitable temperature and pH value. The content of non-oxygen in the biogas is very high, and biogas belongs to secondary Energy, and it is a renewable energy. In the actual fermentation of biogas, there are a lot of fermentation residues. These residues are actually more valuable fertilizers on the market. However, the current technology is simply to apply them in the field and cannot Reasonably reflect the beneficial value in the fer...
