Problems solved by technology

[0002] Using biogas to anaerobically treat animal manure can produce clean energy biogas, but there are the following problems in the process of use. It is very troublesome to remove slag in the biogas tank, especially when the biogas slurry in the biogas tank is discharged, it is difficult to meet the discharge standards. It has a great impact on the environment. If it is a small farm household, the discharge of biogas slurry is small, and the impact on the environment can be tolerated. For large-scale industrial farming of centralized livestock breeding, simple biogas treatment of animal manure is obviously unable to meet environmental protection. requirements

Embodiment Construction

[0035] like figure 1 Among them, a method for harmless treatment of animal manure includes pretreatment - biogas digester treatment - biological filter material filtration - artificial wetland purification:

[0036] 1) Pretreatment, the pretreatment includes a crushing step and a flotation step. The crushing step is to crush the collected animal feces into blocks smaller than 1CM×1CM; the flotation step is to put the blocks in the crushing step into a pool. , There is an air intake pipe at the bottom of the pool. First, the air is inflated into the pool through the air intake pipe, so that the manure water in the pool is repeatedly circulated from bottom to top. The manure water is fully mixed and then put into the biogas tank. During the flotation process, the The body can fully absorb water, so that the comprehensive water content of the manure water is not less than 85%.

[0037] 2) Biogas tank treatment, put the pretreated manure water (raw material) into the anaerobic st...

Abstract

The invention discloses a method and device for animal feces innocent treatment. Through pre-treatment, methane tank-based treatment, biological filter filtration and constructed wetland-based purification, biogas slurry produced from manure water in a methane tank by biogas production flows through a constructed wetland mixed with microbes and is used for animal manure water purification treatment so that animal culturing farm manure water pollutant discharge is improved and environmental pollution is reduced. The biogas subjected to anaerobic treatment is used as a biofuel, sediment at the bottom of the methane tank can be processed to form fertilizer, and the biogas slurry is subjected to constructed wetland filtration, plant root absorption and microbe digestion so that requirements of the livestock and poultry industry pollutant discharge standard (GB18596-2001) are satisfied. Through effective combination of the methane tank and the constructed wetland prepared from a high-performance biofilter, the device and the method have the advantages of simple construction, low operation cost, good effects, no secondary pollution and environment improvement and really realizes animal culturing farm manure water effective-treatment and no pollution of positions surrounding a field.

Description

technical field [0001] The invention relates to a method for purifying and treating animal manure (pig, cow, chicken, duck, goose) and manure water, and can achieve harmless treatment of animal manure. Background technique [0002] Anaerobic treatment of animal manure with biogas can generate clean energy biogas, but there are the following problems in the process of use. It is very troublesome to clean the slag in the biogas digester. It has a great impact on the environment. If it is a small farm household, the discharge of biogas slurry is small, and the impact on the environment can be tolerated. For large-scale industrialized breeding of centralized animal husbandry, the simple biogas treatment of animal manure is obviously unable to meet the environmental protection requirements. requirements. SUMMARY OF THE INVENTION [0003] The present invention provides a method for harmless treatment of animal excrement combined with a biogas tank, and equipment used for the ha...
