Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
Examples
Referring to fig. 1, a livestock and poultry corpse recycling treatment system provided by an embodiment of the present invention is shown in fig. 1, and the system includes a composting room including a composting bin; a concrete ground is arranged inside the composting bin; a base material layer with the thickness not less than 30cm is fully distributed on the upper flat layer of the concrete floor; a first animal carcass layer is arranged on the upper portion of the base material layer, a first covering and filling material layer covers the upper portion of the first animal carcass layer, and the distance between the upper surface of the first covering and filling layer and the upper surface of the first animal carcass layer is not less than 30 centimeters;
wherein the first carcass layer comprises a plurality of carcasses, and the distance between two adjacent carcasses is not less than 15 centimeters and is separated from each other by the first covering and filling material layer; the distance between the animal carcass adjacent to the wall of the compost bin and the wall is not less than 30 cm.
In practical application, a plurality of animal carcass layers can be arranged in the same composting bin to achieve the purpose of simultaneously achieving larger processing capacity. Specifically, the embodiment of the present application may further provide that an upper portion of the first covering and filling material layer is disposed on a second animal carcass layer, and a second covering and filling material layer is disposed on an upper portion of the second animal carcass layer; the distance from the upper surface of the second overlying filling layer to the upper surface of the second animal carcass layer is not less than 30 centimeters;
the second carcass layer comprises a plurality of carcasses, and the distance between two adjacent carcasses is not less than 15 centimeters and is separated from each other by the second covering and filling material layer.
When the filling material is selected specifically, the carbon-nitrogen ratio of the base material layer, the first covering filling layer and the second covering filling layer is 15-35: 1. the base material layer, the first covering and filling layer and the second covering and filling layer are made of one or a combination of more of wood chips, sawdust, crushed straws, straws of various crops, animal wastes and composted finished products. Further, the base material layer is made of sawdust, the first covering and filling layer is made of one or a combination of several of crushed straws, straws of various crops, animal wastes and composted finished products, and the second covering and filling layer is made of sawdust.
Many organic materials can be used as filler materials, and different materials differ in terms of workability, cost, and physical properties. The choice of filler material should primarily take into account two aspects: carbon to nitrogen ratio (C: N ratio) and physical properties.
The carbon to nitrogen ratio directly affects the growth metabolism of the microorganisms. C in the compost: the ratio of N should be between 15: 1 and 35: 1, if the carbon is too little, the high nitrogen content is converted into ammonia, producing an off-flavor; if too much carbon is present, low nitrogen levels can limit the activity of the microorganisms, resulting in slow decomposition of the carcass, C: the N ratio is gradually reduced in the composting process. Keeping the whole C: the ratio of N is balanced, and no excessive attention is needed. Common compost filling materials include wood chips, sawdust, rice straw, and straws of various crops (after being crushed), animal wastes, and composted finished products.
C: the ratio of N can be found in Table 1:
| filling material | Carbon to nitrogen weight ratio |
| Saw dust | 200－750：1 |
| Straw | 48－150：1 |
| Corn stalk | 60－73：1 |
| Compost finished product | 30－50：1 |
The physical properties of the filler material include two main aspects, namely, the particle property, and the filler material needs to have proper particles to facilitate free air entry. Too small a particle size will inhibit air inflow, slow down the composting process and produce off-flavors; too large a particle size will reduce the composting temperature and slow down the decomposition activity of the microorganisms. Secondly, the filler material has certain adsorption function to absorb the odor generated in the compost.
The underfill material is preferably selected from the group consisting of relatively solid wood chip-like materials of slightly larger dimensions, and having a certain internal porosity. Can bear pressure in the compost and keep better air permeability. The filler material of the intermediate layer can be selected from the group consisting of C: the ratio of N and the pores and particles of the materials are selected, and a mode of mixing various materials can also be adopted, and a proper amount of finished compost containing microorganisms is recommended to be added. Sawdust-like material is preferably used as the top-covering filler material.
Some commonly used filler materials are characterized by table 2:
further, the number of the composting bins is at least three. The most basic composting room should contain at least 3 silos, which, depending on the size of the farm, may also have the function of storing both filling material and loading equipment. According to different states of the plant in the composting stage, the plant is divided into a filled corpse, a first thermal cycle and a second thermal cycle. Table 1 exemplifies management of a composting room circulating for 15 days.
TABLE 3 management of composting houses
Note: the number of days of circulation is determined by a combination of various conditions and does not represent the actual management time.
Furthermore, an air pipe is arranged at the upper part of the concrete ground surface, and a plurality of through holes are formed in the pipe wall of the air pipe; the base material layer is arranged on the upper part of the breather pipe. The compost bin also comprises a temperature sensor for acquiring the temperature in the compost bin. The temperature sensor can adopt an industrial stainless steel probe thermometer with the length of more than 90cm so as to conveniently measure the temperature in the deep compost. For bad smell and slow decomposition caused by insufficient ventilation, forced ventilation can be considered under appropriate conditions to increase oxygen supply inside the compost. For example, the bottom of the device can be paved with pipes drilled with holes, gravel channels and the like. But the problems of overlarge ventilation quantity, fly entering from the ventilation hole and the like are avoided.
When the system is in use:
a. building up a fill material base
The floor of the composting bin is typically a solid floor of concrete or the like, above which a filling material is placed with a thickness of at least 30 cm. The carcasses were placed in layers, separated by filling material and covered with a 30cm thick layer of filling material. As shown in fig. 1. The weight, amount of carcass, and type, amount of filling material were then recorded.
b. Monitoring the first thermal cycle
The compost is checked daily/every second day and when it is found that there is a sag in the compost, the filling material should be appropriately replenished to ensure that all carcass parts are completely covered. The temperature was checked and recorded every day/every two days, and should be collected at multiple locations in the compost, particularly near the last carcass added. The temperature will reach 54 to 66 c within a few days to weeks. The compost reaches above 54 c and begins to record at temperatures, typically for one week. Waiting until the temperature drops for one week, and preparing for turning over compost.
Table 4 estimates of days of the first Heat cycle based on carcass weight
| Weight of carcass (kg) | Estimation of the number of days of the first thermal cycle |
| 0－5 | 15 |
| 5－10 | 22 |
| 10－135 | 45 |
| 135－340 | 60 |
c. Turning compost
When the fertilizer is turned over, if the humidity is low, a proper amount of water needs to be added before turning over. The bottom of the second empty bin was filled with 30cm of filler material. The compost was transferred to a second bin using a loader and finally covered with 30cm thick filler material and the date of inversion and volume of filler material used were recorded.
d. Monitoring the second thermal cycle
The temperature of the compost after removal was monitored and recorded daily. The composting temperature is kept above 54 ℃ for one week, and the composting is finished after the temperature is subsided. The second thermal cycle is approximately the same number of days as the first thermal cycle. The whole process takes approximately 50 to 170 days, or even longer. The time required depends on the filling material, temperature, humidity, management technique and animal size, among other factors.
e. Checking compost finished product
After composting, if there are macroscopic soft tissue masses, it is necessary to re-run a thermal cycle. If the bone is not completely decomposed after composting, it can be composted again, preferably as a base material. Whereas for long non-disintegrating bones a separate treatment is required. The color of the finished product of the integral compost is dark brown to black, the material becomes uniform and consistent, the finished product is similar to granular materials of humus soil and potting soil, and the finished product has a slight mildewed smell.
In a word, the system provided by the application has the advantages of simple and reasonable structure and convenience in use. The system is suitable for treating various animal species including poultry, pig, sheep, cattle and the like. General carcasses can be composted through the system, except for animals that die from anthrax or toxic substances. And has the advantages of low cost, environmental protection, biological safety, economic benefit and the like.
