In recent years, the rapid development of the intensive pig-raising industry has resulted in a large amount of excrement not only deteriorating the air, resulting in serious eutrophication of rivers and lakes, but also endangering groundwater. Controlling the environmental pollution of feces, urine, waste water, and odor in swine production to protect the ecological environment is the need for the development of the pig farm itself and the requirement for environmental protection. There are mainly the following methods for handling feces, urine and sewage.
1, heap fermentation used as a farmyard fertilizer. Use dry excrement alone for collection, accumulation and fermentation for farmyard manure; minimize flushing water, waste water, and waste residue for biogas production for lighting, heating, and irrigation with water.
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. There are also certain benefits to the control of pig parasites.
2, made of refined organic fertilizer. For example, it is possible to ferment feces into refined organic fertilizers using Kinpo-type fermentation aids. This product is mainly composed of fungi, yeasts, actinomycetes and bacteria and other beneficial microorganisms. They are not mutually exclusive in the fermentation process. Antagonism, cooperative combat, relying on organic waste as a nutrient source, utilizing the powerful "biochemical reactions" formed during the massive and rapid propagation process to complete the "deodorization", "decay", "insect killing", and "debris" of organic waste. "Bacteria" treatment process, to achieve harmless, resource-based waste disposal purposes.
3, fermented into feed. In the pig manure, add a certain proportion of the Kinpo II type feed fermentation aid, and then feed the appropriate amount of straw, sawdust and other materials with high carbon to nitrogen ratio after fermentation. The Golden Baby II feed fermentation aid is a high-performance strain obtained through a series of high-tech methods such as separation, screening, mutagenesis, purification, and rejuvenation using the latest international microbiological engineering and technological achievements of Europe, the United States, Japan, and South Korea. A dry-powder live microbe preparation prepared by compounding with other special effects substances.
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. 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.
In addition, the Jinbao Kangsa Technology Co., Ltd. developed by Beijing Huaxia Kangyuan Technology Co., Ltd. can be used to raise pigs, no need to wash the piggery, and no sewage to be discharged, which can be used for deodorization, environmental protection, energy saving, food saving, and resistance. The long-term disease-promoting, water-saving and labor-saving functions have truly achieved the effect of pollution-free and zero-emission pig farms.T Shape Black Light Blue Lamp, T5 Black Light Blue Lamp, T8 Black Light Blue Lamp, T9 Black Light Blue Lamp, T10 Black Light Blue Lamp
