Livestock excrement treatment device and method

Abstract

The invention relates to technical field of livestock excrement treatment and discloses a livestock excrement treatment device. The invention further discloses a method for treating livestock excrements by adopting the livestock excrement treatment device. According to the device and method disclosed by the invention, high-moisture-content livestock excrements are continuously filtered and treatedin the turning process in a short time, one part of the moisture is removed, the moisture content of the livestock excrements is reduced, the livestock excrements are prevented from being agglomerated, and the moisture content favorable for rapid growth of fermentation organisms is provided for subsequent fermentation of the livestock excrements. According to heating in a certain time, pathogenicmicroorganisms in the livestock excrements are killed, the odor is reduced by 90% or higher, any pollution or other hazards to the environment is avoided after the excrements are discharged, and theharmless standard is reached.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry manure treatment. More specifically, the present invention relates to a livestock and poultry manure treatment device and method. Background technique [0002] In China, the rapid development of the livestock and poultry breeding industry has played an important role in the development of the rural economy and the increase of farmers' income. A large amount of excrement will be produced in the livestock and poultry breeding process, especially in large-scale or large-scale farming. It is necessary to carry out harmless treatment or resource utilization of these feces, otherwise it will pollute the environment. However, at present, less than 5% of my country's livestock and poultry breeding enterprises carry out harmless treatment or resource utilization of livestock and poultry manure, and it is imminent to control the pollution of livestock and poultry manure. [0003] For the tr...

Problems solved by technology

However, at present, less than 5% of my country's livestock and poultry breeding enterprises carry out harmless treatment or resource utilization of livestock and poultry manure, and the pollution of livestock and poultry manure has reached an imminent level

However, this compression dehydration method has the following problems, that is, compaction occurs after the surface layer is dehydrated, and the interior cannot be effectively dehydrated, and the moisture content of 50-55% required by microbial fermentation cannot be reached.
