Integrated sewage treatment device for livestock and poultry excrement

Abstract

The invention relates to the technical field of livestock and poultry excrement treatment, and discloses an integrated sewage treatment device for livestock and poultry excrement. A water accumulationcavity is arranged under a partition net, and an extrusion and water removal mechanism is arranged above the partition net, wherein the extrusion and water removal mechanism can be used to extrude excrement on the partition net for removing water, so that water in the excrement is collected in the water accumulation cavity. The excrement can be extruded and then discharged in sequence, and separation of water in the excrement is realized, so that subsequent fermentation treatment of the excrement is facilitated, and adverse influence on the environment caused by discharge of liquid excrementis prevented. After liquid excrement is filtered for a certain time, a porous filtering carbon layer contains filtered substances such as excrement residues and the like, and then the porous filteringcarbon layer can be heated and sintered by utilizing a high-temperature sintering treatment column, so that attachments on the porous filtering carbon layer are removed, subsequent filtering capability is improved, and the effect that the filtering effect is weakened due to the fact that pores in the porous filtering carbon layer are enlarged by long-term flushing of liquid excrement is effectively compensated.

Description

technical field [0001] The invention relates to the technical field of poultry manure treatment, in particular to an integrated sewage treatment device for poultry manure. Background technique [0002] Livestock manure is one of the most important pollution sources that pollute the environment. If the harmful gas in the poultry manure is not removed in time, the odor will multiply, resulting in dirty air and the breeding of mosquitoes and flies. The sewage in the poultry manure is easy to accumulate. As a result, the number of harmful bacteria in the environment increases, the sewage seeps into the ground, damages the roots of nearby plants, and the groundwater content exceeds the standard. Therefore, the sewage treatment device is an indispensable purification equipment for breeding poultry and livestock. [0003] However, the sewage treatment devices currently on the market generally have a relatively simple structure, and the ability to recover feces is insufficient, and ...

AI Technical Summary

Problems solved by technology

[0003] However, the sewage treatment devices currently on the market generally have a relatively simple structure, and the ability to recover feces is insufficient, and cannot effectively separate the moisture in the feces from the feces, which leads to excessive moisture in the feces during subsequent fermentation and other operations. Fecal water accumulates and produces a foul smell, and in the last step of final filtration of fecal water, activated carbon adsorption or membrane filtration is generally used. After long-term use of this filtration method, tiny feces will accumulate, affecting subsequent Filtration effect and filtration capacity
