preparation example Construction

[0073] In an optional embodiment, the preparation method of the bio-organic fertilizer comprises the following steps:

[0074] Pretreating the solid manure, mixing the pretreated solid manure, biogas residue, plant powder, plant ash and sludge according to the proportion, and stirring evenly to obtain a mixture;

[0075] The mixture is added to a fermenter, and fermented after adding a starter;

[0076] After the fermentation is finished, the fermented product is dried until the water content is 8% to 12%;

[0077] Add urea, chitin, chitosan and superphosphate to the dried fermented product according to the ratio, stir and mix evenly, and then send it into a granulator for granulation to obtain the bio-organic fertilizer;

[0078] Preferably, the fermentation temperature is 25-50° C.; the fermentation time is 20-30 days.

[0079] Optionally, drying the ferment to a moisture content of 8%, 9%, 10%, 11% or 12%

[0080] Optionally, the fermentation temperature is 25°C, 30°C, 3...

Embodiment 1

[0096] A method for treating manure from a farm, said method comprising the following steps:

[0097] Carry out solid-liquid separation treatment on feces to obtain solid feces and liquid feces;

[0098] The liquid manure enters the liquid manure adjustment tank for uniform mixing, removes impurities and adjusts evenly, then enters the anaerobic reactor for anaerobic fermentation, and obtains biogas, biogas slurry and biogas residue through the three-phase separator of the anaerobic reactor; The oxygen fermentation conditions are as follows: the temperature is 40° C., the time is 5 hours, and the pH value is 6.

[0099]The biogas slurry enters the sedimentation tank for sedimentation and separation, and then is transported by a power pump for planting vegetables;

[0100] The biogas enters the biogas purification device for purification, and the purified biogas generates electricity through the biogas power generation device;

[0101] The solid manure is pretreated by drying...

Abstract

The invention relates to the technical field of fecal treatment and in particular to a fecal treatment method and system used in a farm. The fecal treatment method comprises the following steps: performing solid-liquid separating treatment on feces to obtain solid feces and liquid feces; feeding the liquid feces into a liquid feces adjusting pond, mixing uniformly, and then feeding the feces into an anaerobic reactor for anaerobic fermentation to obtain biogas, biogas slurry and biogas residues; feeding the biogas slurry into a settling pond for precipitation separation, feeding the biogas into a biogas purifying device for purification, and generating electricity by the purified biogas through a biogas generating device; and pre-treating the solid feces, feeding the pre-treated solid feces and biogas residues jointly into a fermenting pond, adding a fermenting agent for fermentation, and after fermentation, drying and granulating the mixture to obtain a biological organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of excrement treatment, in particular to a method and system for treating excrement in a farm. Background technique [0002] In recent years, with the rapid development of pig, cattle and cattle breeding industries and the continuous expansion of production scale, the treatment of a large amount of feces produced every day has brought new problems to people. Although manure is a good fertilizer, it is helpful for the good growth of crops, but if the manure is directly applied to the soil without treatment, a large amount of heavy metals and antibiotics in the manure will change the composition balance of the soil, and even pollute the soil. If it is applied to the soil for a long time, it will inevitably cause potential pollution risks to the soil environment and agricultural products, and cause new pressure on the ecological environment. In addition, improper treatment of feces will not only seriously poll...
