Last time, when we introduced the technology of pig manure treatment, we talked about the shortcomings of the water flushing method. Is there any way to replace the water pumping method and it is efficient and low-cost? The answer is yes. Today, Hui Nong.com will introduce another method of treating pig manure: dry manure, and talk about its advantages.
There are three advantages to using the dry-cleaning method to treat manure:
1. Less investment
Compared with the water-flushing method, it is necessary to construct an extremely large collecting tank, and the dry-cleaning method does not require such a large investment. Under normal circumstances, the construction of the sump by the dry shovel method requires only one quarter of the volume of the sump, so that the construction cost of the sump can be greatly reduced.
2. Maintenance easy
Compared with the maintenance cost of the entire process of the flushing method, the maintenance cost of the dry cleaning process is much lower. The dry cleaning method does not require a sewage pump to work day and night. Due to the separation of excreta and urine, the sewage from the pig pool can basically reach the standard of normal discharge. Basically, no precipitation treatment is required. Why do advanced pig farms promote dry and dung methods? Because there are these five advantages!
3. Less water consumption
The pig farm using the dry-cleaning method does not need to use a high-pressure water gun to repeatedly rinse the pig house, and the amount of water consumed can be greatly reduced. According to big statistics, pig farms using the dry-cleaning method at the same scale can save about two-thirds of the water on the farms using the flushing method. In this year, the cost of water saved is also very substantial.
Of course, although the dry cleaning method has many advantages, the shortcomings are obvious, that is, it is more labor-intensive, and it is more troublesome in actual operation and requires higher labor costs. However, compared with the cost of labor, the cost of water conservation, the maintenance cost of the manure cleaning system, and the initial input cost can definitely save more money. If a fertilizer plant can cooperate, the separated pig manure is undoubtedly more suitable for organic fertilizer, and the quality of the fertilizer produced will be higher. For many pig farms in developed countries, the income of organic fertilizer is enough to pay for the extra labor costs.
In the long run, dry and clean manure can save more costs, and qualified farmers may wish to examine it carefully and try again. The pig farm waste treatment technology is progressing, I believe that there will be more and better pig manure treatment methods in the future!
