Pig manure treatment
Pigs are covered with treasures, there is no waste, and even pig manure is an excellent fertilizer for agriculture. Under the condition of modern pig farming, the treatment of pig manure is a key environmental protection technology, otherwise it will cause environmental pollution. So how to deal with pig manure? To introduce you to the treatment methods are as follows:
1. Generally, the dry fecal removal method is used, the sewage is relatively less, and it is easy to be treated; if the automatic fecal removal method is adopted, the amount of sewage is large, it is necessary to go through solid-liquid separation before treatment and utilization.
two。 In daily life, animal manure can basically be used as plant fertilizer. in general, animal manure from breeding farms can be sold to rural areas, or farmers can use it to make fertilizer for plants and bury it in the soil of plant roots. this kind of fertilizer can provide plants with some nutrients needed for the plant growth cycle, so that plants can grow more healthily.
3. Secondly, pig manure can also be used for biogas lighting, burning and cooking, etc., and then the waste pig manure made of biogas can be provided to plants as fertilizer again.
4. Pig manure composting fermentation has attracted much attention because of its low cost, effectively killing pathogens and deodorization, improving the bad physical properties of livestock and poultry waste, reducing the volume of livestock and poultry waste and achieving a complete and stable effect, and has become one of the important ways of harmless and resource utilization of livestock and poultry waste. Fecal starter can greatly optimize this process and produce more reassuring organic fertilizer in view of the shortcomings in the process of pig manure fermentation.
5. Establish a sedimentation tank, at least a third-stage sedimentation tank, after the three-stage precipitation, the feces will basically become clear and can be discharged. The establishment of a three-stage sedimentation tank is not a big problem for a small farm.
