A method of raising ecological pigs by using slag, liquid and gas separate circulation fermentation tank

Abstract

The invention discloses a method for utilizing dregs, liquid and gas to separate a circulating and fermenting tank separately to raise ecological pigs. The method comprises the following steps of hardware construction, wherein according to requirements of the circulating and fermenting tank, a pig farm waste treating pool is constructed; system erecting, wherein waste dregs and waste liquid of a pig pen are communicated with a feeding system of the circulating and fermenting tank through a pipeline, and a biogas slurry tank of the circulating and fermenting tank is connected to the pig pen through a wash-back water pipe; washing the pig pen, wherein a booster pump on the wash-back water pipe is started, biogas slurry after fermentation is driven to wash the pig pen, and the pig pen is washed according to the frequency needed in four seasons in a year; fermenting waste dreg liquid, wherein the waste dregs and the waste liquid of the washed pig pen enter a biogas tank for anaerobic digestion, and after the fermentation is completed, the generated biogas slurry is automatically collected to the biogas slurry tank. The invention aims at providing the method for utilizing the dregs, theliquid and the gas to separate a circulating and fermenting tank separately to raise the ecological pigs and providing an ecological circulating, fermenting and breeding method for facilitating energy saving, environment protection, disease resistance and feed saving of pig farm breeding.

Description

technical field [0001] The invention belongs to the field of livestock breeding, and relates to equipment for harmless treatment and recycling of waste excreted from farms, in particular to a method for raising ecological pigs by using slag, liquid and gas to separately separate and circulate fermentation tanks. Background technique [0002] According to comprehensive statistics, in China, pork is the most consumed meat. To a certain extent, the price fluctuation of pork can even reflect some indicators of the state of the economy; pork is probably the most sensitive dish on the table. up. [0003] At the same time, my country, as the world's largest pig breeding country, plays a pivotal role in modern economic development, but it also brings challenging environmental pollution problems. The pollution hazards of aquaculture wastewater mainly exist in the following aspects: [0004] 1. The discharge of feces and urine is large and the treatment is difficult. [0005] 2. Th...

AI Technical Summary

Problems solved by technology

[0004] 1. Large amount of excrement and urine sewage discharge, high difficulty in treatment

[0005] 2. The cost of sewage treatment is high, and the treatment effect is difficult to guarantee, resulting in an increasing cost of breeding

[0007] 4. Aquaculture wastewater directly affects people's health

[0009] 2. Feeding fine feed and abuse of antibiotics lead to poor flavor of pork and enrichment of harmful elements, causing food safety problems

[0010] 3. Concentrated captive breeding and abuse of antibiotics lead to extremely poor resistance of pigs, common sick and dead pigs, and small profit margins or losses for farmers

[0011] 4. End treatment is the main method, ignoring the resource value of livestock and poultry manure

[0012] 5. Excessive application of untreated pig manure will easily cause crop yield reduction
