Ecological livestock farms' attention issues
1. Reasonable site selection
(1) The site of ecological livestock and poultry farms should be selected from livestock and poultry farms, trading markets, slaughterhouses and factories that are far away from residential areas, traffic arteries, established sites, and the distance should be more than 300 meters.
(2) Conditional can be selected on the slope above the irrigation canal in the planting area (standard farmland) so that manure irrigation canal can be used to apply manure water nearby.
2. Scientific planning and construction
(1) The scale of farms can be farmed with fertilized farmland (cultivated land, garden land, and breeding ponds) according to supporting irrigation. There are 5 pigs (0.5 cattle, 10 sheep) per area (1 mu = 667 square meters, the same below). The standard for 150 broilers, 100 hens, and 75 rabbits was planned.
(2) Livestock and Poultry Farms can arrange barnyard plots for each head of pigs (0.1 cattle, 2 sheep, 10 poultry birds, 6 poultry birds, and 5 rabbits); 2% of the construction land is determined; the land for feed processing and storage is determined according to 3% of the construction space for the pig house.
3, ecological process design
(1) Reduce the process design should consider: First, rain and sewage diversion. Large mouthwash or water joint technology is adopted to separate rainwater and sewage and reduce sewage discharge. Second, urine separation. The pig bar design should achieve the separation of solids and liquids (feces and urine), and the drinking water supply can use water-saving appliances such as automatic drinking fountains. At the same time, the flushing water consumption should be strictly controlled, and the operating procedures of first flushing and re-circulation should be adopted to reduce the solids and water consumption in the manure water.
(2) Innocuity process First, regular excrement. Every day, 9:00 am and 3:00 pm, dry manure is cleared regularly and transported to the composting site for uniform decomposed treatment. Second, by building a biogas tank that is compatible with livestock and poultry, it will be discharged to a fishing pond or supporting farmland. The general measures for sewage treatment are: sedimentation tank (removal of sediment, impurities, etc.) → collection tank (capacity is the amount of sewage generated in the livestock farm for 1 day) → acidification tank → (12 hours of acidification, the capacity is equivalent to livestock and poultry Half-day sewage volume) → Anaerobic pond (fermentation 7 to 10 days, capacity equivalent to 7-10 days of sewage in livestock and poultry farms) → Aeration tank (Aeration for 24 hours, capacity equivalent to 1 day of sewage in livestock and poultry farms Quantity) → sedimentation tank → constructed wetland (field plover, pond aquatic plants, etc.) → discharge irrigation.
(3) The resource-based process is mainly based on the return of land to the nearest site, so that dry manure will be released after maturity and used in fruits, vegetables, fish ponds, etc. Sewage (urine) water is treated by anaerobic and aeration, and then after irrigation in the pond, the matching irrigation is pasted.
