Description

Method for removing feces

The present invention relates to a method for processing organic building materials, in particular to a method for removing poultry manure from poultry farms. Background technique

With the development of society, the breeding of poultry has already evolved from small-scale one-house free-range breeding to large-scale intensive breeding. The problem caused by this is that in farms of various sizes, poultry are raised at high density, and a large amount of manure is produced every day, which is usually not cleaned in time and the odor is pervasive. Poultry houses have poor ventilation and often cause blasts, which can cause large numbers of poultry deaths. Therefore, for the poultry industry, how to properly handle poultry excreta is the key to determining the sustainable development of the industry.

There are various methods for treating poultry excrement. Common methods include removal and reprocessing, that is, removing poultry excrement and thoroughly disinfecting the poultry house with a germicidal agent. The removed poultry excrement needs further manual processing, including various processes such as drying, fermentation, and pulverization. Make it an organic feed. Chinese invention patent applications 99124603.9; 01144475.4, Japanese patent applications JP 57-78997 and JP 11-206321 all disclose similar treatment methods. These processing methods require special equipment and complicated processes, which greatly increase the cost of processing poultry excreta.

Another method is an ecological waste treatment method, which uses natural biological chains to solve the problem, that is, raising earthworms with poultry manure; earthworms absorb organic components in poultry manure and emit odorless earthworm manure; and grown earthworms It can also be consumed by poultry, thus forming a good ecological cycle. This method is common in current rural areas. In this method, the feces of poultry are usually mixed with biodegradable, high-humus materials such as fertilizers to form an environment suitable for the growth of earthworms. However, the introduction of fat mud brings another problem, that is, it also forms another pollution source, which makes the air in the chicken house more turbid. For this reason, some large-scale farms usually remove poultry waste by mechanical or manual means, and transport it to another place separated from the poultry breeding space to raise earthworms for further processing of waste. A similar method is described in U.S. Patent No. 4,262,633. Because raising poultry and disposing of waste in different locations requires a lot of extra manpower, Material resources, increasing costs; and the timely and synchronous treatment of poultry excrement.

These problems in the prior art have led people to work to find an ecological, environmentally friendly, and low-cost method for processing poultry excreta in real time and synchronously, so as to achieve sustainable development of the poultry breeding industry. Summary of the invention

The invention aims at the problems existing in the prior art, and provides a method for synchronously removing poultry excrement in a poultry house. The method includes the following steps: 1. Laying clean manure in a poultry excrement collection device in a poultry house; 2. Gradually mixing the excreta produced during poultry breeding with clean manure, and poultry 'excreta and clean manure When the proportion of feed reaches 30%: 70%, put in earthworms; 3. Wormworms continuously swallow the mixture of poultry excrement and clean manure, discharge odorless and tasteless manure, and multiply the earthworms, and the earthworm manure further interacts with poultry The feces and cleansing materials are mixed together; 4. Control the ratio of poultry wastes to the mixture in the collection device. When the proportion of poultry wastes in the mixture is higher than 60%, add cleansing materials and add The amount is such that the proportion of poultry excreta in the mixture is not less than 35%; 5. The poultry is fed with excess hoe, wherein the clear manure includes peat and clay ore.

The preferred ratio of the above-mentioned manure is that peat accounts for 70% and clay ore accounts for 30%. The manure removal material is preferably processed into round bars of varying lengths, and the diameters can be 6 mm, 8 mm, and 10 mm, respectively.

The thickness of the laying manure is 0.5 m or 0.75 m.

By adopting the method for removing manure of the present invention, the environment of the poultry farm can be improved, the disease resistance of the poultry can be enhanced, the excreta of the poultry can be treated in an environmentally friendly and non-polluting manner, and the operating cost of the farm can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be described below with reference to the accompanying drawings, in which:

FIG. 1 is a schematic view of setting up manure in a collection pit on the ground;

Fig. 2 is a schematic diagram of an ecological chicken breeding system using the method for removing manure of the present invention. detailed description

The specific embodiments of the present invention will be described below by taking a chicken farm as an example.

As shown in Figure 1, in an intensive chicken farm, a concave collection pit 2 is usually dug out on the ground part 1 of the corresponding layered chicken cage to collect chicken manure, scattered feed and water droplets, which are emitted when the chicken is indigested The hydrogen sulfide also accumulates on the ground because it is heavier than air, so the floor of the chicken house is the place with the highest concentration of polluted gas.

The fecal cleansing material 3 of the present invention is composed of peat and clay ore. Both peat and clay ore have a naturally porous structure with a large surface adsorption force, and are often used as adsorbents for waste gas and waste water in industry. In a preferred embodiment, the ratio of peat to clay ore is 70%: 30%. Peat and clay ore can be used directly, or they can be mixed and processed into round bars with different lengths of 6mm, 8mm, and 10mm, and used after drying. The latter works better.

The clean manure material 3 of the present invention is laid in the above-mentioned chicken manure collection pit 2, and the thickness can be 0.5 meters or 0.75 meters. The bottom and walls of the collection pit 1 are made of pebbles and soil so that water and air can be generated. If the cleansing material is processed into various strips, it is best to lay down the cleansing material in order, so that the largest diameter is at the bottom and the smallest diameter is at the top. After one or two days, the droppings such as chicken manure are gradually mixed with the clean manure in the collection pit. When the proportion of chicken manure reaches 30%, earthworms can be placed. The earthworms swallowed the mixture of chicken manure and clear manure in large quantities, and produced odorless and tasteless mound dung. Earthworms grow continuously and reproduce rapidly.

During the above process, keep the humidity of chicken manure and clean manure at about 20%. Under the same humidity conditions, it is beneficial to the chicken manure. After fermentation, chicken manure can effectively remove harmful substances and odors, and further increase its protein content.

Through the adsorption of clean manure, the digestion of earthworms and the fermentation of chicken manure itself, the concentration of harmful gases in the birdhouse is greatly reduced.

The earthworm excrement discharged by the earthworm after swallowing the mixture of chicken manure and the clear manure of the present invention is odorless and tasteless, and it is also an efficient adsorption material. Manure is further mixed with clear manure and bird droppings in the collection pit to become a feed for earthworms. In essence, earthworm dung at this time has the same effect as cleansing.

In the above process, care should be taken to control the mixture in the collection pit. When the proportion of chicken manure in the mixed mash is higher than 60%, clear manure is added in an amount such that the proportion of chicken manure in the mixture is not less than 35%.

The excess wormhill maggots can be used as high-protein feed for chickens, and the broilers raised have strong disease resistance, delicious taste, and can shorten the slaughter period.

The above process is shown in FIG. 2, thus forming a pollution-free benign ecological breeding system. In the description of the invention, all percentages are by weight. As a result of adopting the manure removal method of the present invention, the environment in the chicken house is greatly improved, and the possibility of poultry disease is reduced.

The chicken farm using this method has a much higher operating cost than various existing methods.

Although the present invention has been described by way of specific examples, those skilled in the art should understand that various improvements and modifications can be made to the present invention without departing from the scope and spirit of the present invention.
