Human and animal manure organic fertilizer and preparation method thereof

Abstract

The invention discloses a human and animal manure organic fertilizer which comprises the following raw materials in parts by weight: 70-80 parts of human and animal manure powder and 2-3 parts of a biological fermentation agent, and the biological fermentation agent is prepared from the following raw materials in parts by weight: 18-22 parts of photosynthetic bacteria, 8-10 parts of actinomycetes,8-10 parts of bacillus subtilis, 8-10 parts of saccharomycetes and 8-10 parts of lactobacillus plantarum. The method includes controlling a hydraulic cylinder to work, resetting a sterilizing lamp, turning off the sterilizing lamp and a rotating motor, then adding a biological starter solution into the sterilized human and animal excrement powder for fermentation, and then under the work of a homogenizing mechanism and a driving mechanism, controlling the fermentation temperature to be 18 DEG C to 22 DEG C and the fermentation time to be 6-8 days, so as to obtain the human and animal manure organic fertilizer. The preparation process has the advantages that the process flow is simple, and infectious microbes and antibiotics in the excrement are treated, so that the effect of the human andanimal excrement organic fertilizer is improved.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, in particular to an organic fertilizer of human and livestock manure and a preparation method thereof. Background technique [0002] With the rapid development of the livestock and poultry industry, the problem of breeding pollution has also followed. [0003] In the existing technology, farms generally use machinery or water to wash manure, which produces a large amount of manure and sewage, which is difficult to handle and transport. A large amount of untreated manure seeps into surface water, making manure gradually become the largest source of pollution to local water bodies , feces contain a large amount of volatile substances such as low-molecular ammonia nitrogen and hydrogen sulfide. This kind of feces seeps into surface water in large quantities, making the water source have a foul smell, and human and animal feces have the effect of fertilizer. Therefore, it is necessary to ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, farms generally use machinery or water to wash manure, which produces a large amount of manure and sewage, which is difficult to handle and transport. It has gradually become the largest pollution source of local water bodies. Feces contain a large amount of volatile substances such as low-molecular ammonia nitrogen and hydrogen sulfide. This kind of feces seeps into the surface water in large quantities, making the water source have a foul smell, while human and animal feces have Therefore, it is necessary to face the problem of how to efficiently prepare organic fertilizers from human and animal manure, and propose a human and animal manure organic fertilizer and its preparation method
