How Is Pig Manure Treated? Common Treatment Methods and Techniques Explained

A pig is a treasure from head to tail, with nothing wasted; even pig manure is an excellent fertilizer for agriculture. Under modern pig-farming conditions, pig manure treatment is a key environmental protection technology, otherwise it will cause environmental pollution. So how should pig manure be treated properly? The treatment methods are introduced below:

1. Generally, where the dry manure-cleaning method is used, there is relatively little wastewater and it is easy to treat; where the automatic manure-cleaning method is used, the volume of wastewater is large, so it must first go through solid-liquid separation before being treated and utilized.

2. In daily life, animal manure can basically be used as plant fertilizer. Generally, animal manure from farms can be sold to rural areas, or the farm workers themselves can use it to fertilize plants by burying the manure in the soil around the plant roots. This kind of fertilizer can provide plants with some of the nutrient elements needed during their growth cycle, allowing the plants to grow more robustly.

3. Secondly, pig manure can also be used to produce biogas for lighting, cooking, and so on, and then the waste pig manure left after biogas production can once again be provided to plants as fertilizer.

4. Pig manure composting and fermentation has attracted much attention for its advantages of low cost, effective killing of pathogenic bacteria and deodorization, improvement of the poor physical properties of livestock and poultry waste, and reduction of livestock and poultry waste volume and achievement of a thoroughly stable effect, and it has become one of the important ways to render livestock and poultry waste harmless and turn it into a resource. Manure fermentation agents can address the shortcomings in the pig manure fermentation process, greatly optimizing this process and producing organic fertilizer that people can trust more.

5. Build a sedimentation tank, at least a three-stage sedimentation tank. After the manure water passes through three stages of sedimentation, it basically becomes clear and can be discharged. Building a three-stage sedimentation tank is not a big problem for a small farm.
