NOVELTY - Pig farm dung dirt zero pollution discharge of resource utilization treatment method comprises carrying out feed microorganism process, solid-liquid separation, fermentation bed degradation, methane pool degradation, four level anaerobic fermentation tank degradation, multi-level complex of wetland microbial degradation, and aquatic animal and aquatic plant absorbing.    USE - Pig farm dung dirt zero pollution discharge of resource utilization treatment method.    ADVANTAGE - The method is environment-friendly.    DETAILED DESCRIPTION - Pig farm dung dirt zero pollution discharge of resource utilization treatment method comprises carrying out feed microorganism process, solid-liquid separation, fermentation bed degradation, methane pool degradation, four level anaerobic fermentation tank degradation, a multi-level composite constructed wetland microorganism, and aquatic animal and aquatic plant absorbing. The step of feed microbial treatment includes adding lactobacillus and other beneficial microorganisms in feed of pigs, improving feed digestibility, regulating pig immunity to reduce the use of antibiotics from the source to produce high-quality pig products, reduce emissions stool and fecal nitrogen and phosphorus, heavy metals content, and reduce fecal odor. The step of solid-liquid separation includes collecting pig manure (9) into the collection pits (13), and allowing pig urine water to enter the closed sewage pipeline. Transported directly in the collection pits pig manure and adding microbial filler into the outdoor fermentation bed fermentation, the fecal production into organic fertilizer (10) to a fruit and vegetable garden after fermentation bed degradation or farmland as the basal and top dressing. The step of digesters degradation includes allowing the urinary water to flow to digesters via a closed pipe, biogas degrading treatment by purification, solid purifying and transporting to the fruit and vegetable garden or farm as the basal and top dressing or transporting to outdoor fermentation bed. The step of four level anaerobic fermentation tank degradation includes biogas digesters degrading treatment by purification of sewage (14) to a four anaerobic degradation pool (6) again anaerobic fermentation degradation. The step of multi-level complex of wetland microbial degradation includes after degradation of wastewater, flowing to the wetland complex microbial degradation. The step of aquatic animals and aquatic plants absorbing includes using underwater farming of aquatic animals, and aquatic cultivation of aquatic plants to absorb water, ammonia and other organic compound.
