Description

Technical Field

[0001] The invention relates to the technical field of livestock breeding wastewater treatment, in particular to an automatic treatment system for livestock breeding wastewater. Background Art

[0002] Animal husbandry refers to the large-scale breeding of livestock, such as cattle, sheep and pigs. During the breeding process, the problem that breeders often encounter is the prevention of livestock diseases. Ensuring the healthy growth of livestock is the breeder's greatest expectation, and the most effective way is to ensure the cleanliness and hygiene of the livestock growth environment to avoid the massive growth of bacteria and cause livestock to become sick. At the same time, as the requirements for environmental governance become more and more stringent, the sewage generated to ensure a clean livestock growth environment has become another headache for breeders.

[0003] The most effective way to ensure a clean livestock production environment is to clean the breeding house in time, ventilate it, and remove the livestock excrement in time to avoid fermentation of excrement in the breeding house, which will cause the air in the breeding house to be polluted and affect the healthy growth of livestock. In this process, a large amount of sewage will be generated. The treatment of sewage has brought great troubles to the breeders.

[0004] Under this circumstance, people invented a double-layer breeding house and a matching sewage treatment device. The lower layer is located under the breeding house and is used to clean the livestock's excrement. The upper layer is located inside the breeding house and is used to feed livestock. The lower and upper layers are supported by mesh plates to facilitate the livestock to live on the upper layer and to facilitate the excrement to leak down to the lower layer. The sewage treatment device is set next to the breeding house so that the livestock's feces can be discharged to the designated location in time. For example, the authorized utility model patent with patent number CN201721106055.6 is a typical representative of this type of breeding house. Compared with traditional breeding methods, this structure has achieved great advantages in livestock management. The sewage generated by cleaning the breeding house is also discharged in the designated direction, and has been widely popularized. However, this structure still has shortcomings.

[0005] The livestock excrement discharged from the lower layer is mixed together and flows into the sewage treatment device, where dry and wet separation is carried out and filtration is carried out through a conveyor belt with holes. During long-term use, feces can easily adhere to the conveyor belt and block the filter holes, seriously affecting the filtering effect of feces. At the same time, the interior of the sewage treatment device is directly connected to the breeding house. Harmful gases such as methane generated by feces fermentation in the sewage treatment device will directly enter the breeding house, seriously affecting the health of livestock.

[0040] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0041] like Figure 1-10 As shown, a three-dimensional parking garage includes a livestock house 1 and a sewage collection channel 2 arranged below the livestock house 1. The floor of the livestock house 1 is a support plate 4 connected to the sewage collection channel 2 and provided with a sewage hole 3. The bottom of the support plate 4 is movably connected with a baffle 5 for opening and closing the sewage hole 3. The thickness of the support plate 4 is greater than 15 cm. The sewage hole 3 can serve as a preliminary storage for waste liquid, and the sewage collection channel 2 can perform dry and wet separation operations on the sewage.

[0042] Livestock excrement leaks down through the drainage hole 3 into the sewage collection pipe and is discharged outward through the sewage collection pipe. Under the normal living conditions of the livestock, the baffle 5 closes the drainage hole 3. Its main function is to prevent harmful gases such as ammonia and methane generated by the fermentation of sewage accumulated for a long time in the sewage collection pipe from drifting back into the livestock house 1, affecting the health of the livestock, and further improving the air quality in the livestock house 1. When it is necessary to clean the excrement, sludge and other wastes generated by the livestock, the baffle 5 is first opened to connect the drainage hole 3 with the sewage collection pipe, and then the livestock house 1 is cleaned to improve the living environment of the livestock and ensure their healthy growth.

[0043] Moreover, since the thickness of the support plate 4 is more than 15 cm, the depth of the sewage hole 3 is large, which can temporarily store urine, wastewater, etc. under the normal living conditions of livestock, avoiding sewage accumulation on the surface of the support plate 4 and direct contact with livestock, thereby reducing bacterial damage to livestock, and further improving the physical health of livestock while ensuring the living environment of livestock.

[0044] See also Figure 8 and Figure 9 The support plate 4 is also provided with a flushing system 6, which flushes water toward the surface of the support plate 4 close to the ground. When cleaning the livestock house 1, the feces, sludge and other dirt on the ground of the livestock house 1 are flushed into the dirt collection channel 2, so that the dirt collection channel 2 can separate the feces, sludge and other impurities into dry and wet state, so as to facilitate the separate storage of feces and sewage.

[0046] Compared with the existing method that requires the livestock to be driven out of the livestock house 1 before cleaning the livestock house 1, the flushing system 6 of the present invention can complete the cleaning of the livestock house 1 while the livestock are still in the livestock house 1, and will not cause a stress reaction in the livestock. The operation is simple, convenient and fast.

[0047] Preferably, a plurality of support plates 64 are arranged at intervals in the water trough 61, the water pressure plate 62 is T-shaped and is arranged on the support plate 64, and a plurality of support bars 65 are arranged at intervals at the water outlet 63 of the water pressure plate 62; the support plate 64 is used to support the water pressure plate 62 and ensure the smoothness of water flow in the water trough 61, and the support bars 65 are used to support the water pressure plate 62, ensure the strength of the water pressure plate 62, and prevent the water pressure plate 62 from being trampled by livestock and collapsed, affecting the normal water outlet of the water flushing system 6, wherein the water outlet thickness of the water outlet 63 of the flushing system 6 is 0.3-0.6mm, and the water pressure is 1.5-2 water pressures, so that the flushing system 6 has a good flushing effect.
