High-efficient and environment-friendly treatment process of animal manure

Abstract

The invention discloses a high-efficient and environment-friendly treatment process of animal manure. The high-efficient and environment-friendly treatment process is characterized in that the treatment process comprises the following steps of: A) mixing raw juice pig manure with organic harmless filling material according to the proportion of (4-6): (6-4); B) adding substances after mixing into a treatment pot for performing fermentation treatment; C) heating to 70-90 DEG C in the treatment pot, performing oxygen-consuming fermentation for 12-24h, simultaneously adding and blending a high-temperature bacterial population, stirring to enable the temperature of contents to be uniform, enabling the bacterial population to be uniform and killing harmful bacteria and insect eggs by high temperature; D) switching off, maintaining at the temperature of 70-90 DEG C by relying on heat energy of fermenting organisms, and taking out of a tank after 12-24h; and E) accumulating after taking out of the pot, performing high-pressure air inflation, performing secondary fermentation to realize further loss of water, and fermenting for 12-24h so as to be used as an organic fertilizer for production. The process disclosed by the invention has the innovation points that: a traditional anaerobic way or an anaerobic and oxygen-consuming treatment mode is discarded, and the oxygen-consuming way is directly adopted; the treatment efficiency is high: as the high-temperature bacterial population is adopted and filled in the closed tank capable of being heated, the treatment efficiency is improved by dozens of times, and the harmless treatment can be performed at 24h; and the process is energy-saving and environment-friendly: in addition to initial heating, the high temperature required for fermentation relies on the heat energy which can be produced by the organisms, and the treatment result can be harmless completely.

Description

technical field [0001] The invention relates to a treatment method for feces, in particular to an efficient and environmentally friendly treatment process for livestock and poultry manure. Background technique [0002] With the development of large-scale breeding, the pollution and treatment of livestock and poultry manure have become increasingly prominent, and the corresponding environmental protection measures and technical means are relatively immature and unformed, and the effect is not satisfactory. [0003] At present, comprehensive treatment methods such as direct return to the field, dry-wet separation, anaerobic treatment, biogas energy utilization, aeration, and biological oxidation ponds are implemented for the treatment of livestock and poultry manure. But in practice, there are many problems in technology, equipment and operation in every link, and the operation is very unstable with the change of seasonal temperature. This method also exposes insufficient gas ...

AI Technical Summary

Problems solved by technology

Although the country has invested a lot of money in livestock and poultry manure treatment and biogas anaerobic treatment, the objective effect is hardly satisfactory, and at the same time, it brings more troubles and inconvenience to producers and objectively limits the process of agricultural industrialization
