Embodiment 1

[0022] Example 1: Combining figure 1 , figure 2 , a method for comprehensive treatment and resource utilization of livestock and poultry waste in the present invention is realized by a sewage treatment and resource utilization process and a solid waste treatment process.

[0023] The process of the sewage treatment and resource utilization process is as follows:

[0024] The first process flow: manure enters the regulating sump composed of water pumps and screens, the sieved slag enters the cesspool, and the dry manure also enters the cesspool. After the cesspool is treated, biocompost is obtained. Biocompost processed into granular fertilizers;

[0025] The second process flow: after adjusting the liquid part of the dung in the sump, it enters the hydrolysis and acidification tank, and then enters the anaerobic digestion tank. After that, it is divided into two routes, one is biogas, the other is biogas slurry, and the biogas slurry enters the sedimentation tank. Part of ...

Embodiment 2

[0030] Example 2: Combining figure 1 , figure 2 , the technical process of the present invention is described as follows:

[0031] 1. Process flow description of wastewater treatment and resource recovery:

[0032] 1. Pretreatment of wastewater:

[0033] The sewage enters the sewage treatment station by gravity from the field area through the trench pipe. The waste water first passes through the grid to remove the straw and large suspended objects in the waste water, and the waste water flows into the regulating tank by itself.

[0034] 2. Hydraulic screen:

[0035] The wastewater entering the sump is pumped into the hydraulic screen by the pump to further remove suspended solids and hair and other debris in the sewage, which is more conducive to anaerobic fermentation and avoids blockage of the pipe network. The scum screened out by the hydraulic screen is concentrated into the septic tank for solid composting.

[0036] 3. Hydrolysis and acidification of wastewater:

Abstract

The invention provides a method for comprehensively treating livestock waste and utilizing resource, which is beneficial for reducing local water quality pollution, improving soil environment, improving ecological environment and promoting the sustainable development of agricultural production. The method is realized by a sewage treating and resource utilizing process and a solid waste treating process. The method for comprehensively treating the livestock waste and utilizing the resource, for a large-scale culturing farm, has the advantages of small sludge quantity, low operating cost and the like by adopting biogas fermentation and ecological combinative technology to treat sewage, has the advantages of economy, high efficiency and resource utilization by adopting composting technology to treat dejection garbage, solves partial production and living energies and living energy by adopting produced marsh gas to generate electricity so as to produce direct economic benefit, develops nuisanceless agricultural product bases and realizes agricultural efficiency by taking produced biogas residues and biogas liquid as nuisanceless organic fertilizers.

Description

(1) Technical field [0001] The invention relates to sewage treatment technology, in particular to a method for comprehensive treatment of livestock and poultry waste and resource utilization. (2) Background technology [0002] With the rapid development of animal husbandry, the concentrated production of livestock and poultry manure continues to increase. According to the survey, intensive farms account for a relatively large proportion of the total sewage discharge from livestock and poultry breeding in various places. The development of animal husbandry and the transformation of production methods have promoted agricultural efficiency and farmers' income, but at the same time, it has also brought about a large increase in livestock and poultry manure and sewage and concentrated discharge. [0003] Some harmful substances in feces, such as protein and fatty acid corruption products (also the constituent substances of feces stench), can dissolve in water, making the water s...
