How to deal with pig farm excreta?

Controlling the environmental pollution caused by feces, urine, waste water and odor in pig production, and protecting the ecological environment are the requirements for the development of the pig farm itself and the requirements for environmental protection. There are mainly the following methods for handling feces, urine and sewage.

1, heap fermentation used as a farmyard fertilizer. The pig manure is used for dry manure collection and accumulation as a manure or self-made organic manure; the use of flushing water, waste water, and waste residue is used to produce biogas for lighting, heating, and irrigation of crops. Collect dried pig manure and stack it in a fermentation pond. Sprinkle a layer of quicklime on top of it. Cover it with plastic film or paste it with a layer of mud. Let it ferment for about 1 month and use it as a farmyard fertilizer for planting fruit trees and vegetables. It is also very good for preventing pig parasites.

2, the production of organic fertilizer.

3, wastewater treatment. The treatment process is solid-liquid separation-anaerobic tank-fermentation-aerobic tank fermentation-coagulation-precipitation discharge.

The content of suspended solids in the wastewater discharged from pig farms is very high. The solid-liquid separation can greatly reduce the pollutant load of the liquid part and prevent the subsequent processing equipment from being clogged and damaged.

The wastewater discharged from pig farms is a “three-high” wastewater with high nitrogen, phosphorus, and high harmful microorganisms. Therefore, anaerobic fermentation has become an indispensable key technology in the pollution treatment of the pig industry, which can effectively remove a large amount of soluble organic matter and kill pathogenic microorganisms. Biogas fermentation technology is the best anaerobic fermentation and has been widely used. Also commonly used are upflow anaerobic sludge blankets.

Natural aerobic fermentation uses natural water and microorganisms in the soil to purify wastewater. Commonly used water aerobic fermentation, through the aerobic pond, facultative pond, anaerobic pond culture ponds to treat wastewater, can reach the secondary treatment standards.
