Based on the livestock manure drying system, the embodiment of the application provides a livestock manure drying method, which comprises the following steps:
an initial effect dehydration step, wherein a ventilation system is adopted to supplement oxygen for aerobic bacteria in solid manure in the storage room 10;
and (3) a post-effect dehydration step, namely heating the solid manure by adopting a heating system when the water content of the solid manure is reduced to a first threshold value.

Wherein, NC in the storage room 10 in the primary dehydration step is relatively stable, and the heat generated by the reproduction of aerobic bacteria can heat the solid manure to 70 ℃. Of course, appropriate microorganisms may be added to address the ammonia nitrogen problem.
As shown in fig. 5, the air supply device used in the preliminary dehydration step is a centrifugal blower, which can supplement oxygen for aerobic bacteria and quickly reduce the water content of solid manure to 35%. This is when the first threshold is reached, at which time the aerobic bacteria have lost activity and are not capable of generating heat. And then, through a post-effect dehydration step, the water content of the solid manure is further reduced to 18% (namely, the water content reaches a second threshold value), so that the water content of the solid manure is very low, and the solid manure can be directly sent to a granulation device for manufacturing the biomass fuel without adding other substances such as straws and the like.
The oxygen supplementation is implemented when solid manure is fed into the storage room 10, the size design of the storage room 10 is designed based on the practical culture scale, the solid manure produced by culture can be guaranteed to be about 5-7 days, the storage room 10 can be filled with the solid manure, and the heating system can generally select to start to work after the storage room 10 is full, so that the energy consumption is reduced. Therefore, it can be understood that the size and number of the warehouse 10 can be selected by the breeding enterprises according to the breeding scale, so as to facilitate the treatment of the excrement.

In addition, the finished product made by the granulating equipment can be supplied to a hot blast stove, so that the cost of the post-effect dehydration step can be reduced.
In detail, the method further comprises a feeding step: solid manure is added to the storage house 10.
In addition, in the feeding step, a mixture of solid manure and filtering chaff can also be added, and the filtering chaff is the chaff after liquid manure is filtered. Among them, chaff in a sewage treatment system of a farm (such as a sewage treatment system of a farm disclosed in patent application publication No. CN 209039292U) can be used as the filtering chaff. It should be noted that, the filtering chaff is not added for reducing the water content of the excrement like adding straw in the prior art, but the filtering chaff is a material required for treating the sewage in the liquid excrement, and the filtering chaff is impregnated by the sewage and has high humidity. The method can utilize the filtering chaff, dehydrate the chaff together and use the chaff as a raw material for preparing the biomass fuel, and is more beneficial to the back-end treatment of breeding enterprises.
Therefore, the method can be used for treating the solid manure independently, can also be used for treating the solid manure and the filtered chaff into raw materials suitable for granulation, better treats pollutants at the rear end of a breeding enterprise, and can generate new economic benefits by using the dehydrated substances as the raw materials for biomass fuel production, thereby being more economic and environment-friendly.
