[0009] A further improvement of the present invention is that the walls of the breeding farm are made of prefabricated glass light stone bricks, which can not only reduce the noise inside the pens, but also absorb the odor inside the pens.

[0010] A further improvement of the present invention is that the glass pumice prefabricated brick has an extended area of ​​10000cm per gram and a density of 0.2-1g / cm3.

[0011] A further improvement of the present invention is that the dry-wet separation tank is a separation tank with a grid structure, the grid gap of the dry-wet separation tank is 5-10mm, the grid is used to achieve solid-liquid separation of farm waste, and the intercepted solid pollutants are transported out for treatment by manual or mechanical scooping.

[0012] A further improvement of the present invention is that the sedimentation tank is an inclined tube sedimentation tank.

[0013] A further improvement of the present invention is that the length of the water trough is 100m, and glass pumice is laid on the bottom of the water trough, and aquatic plants are planted in the water trough.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0023] like Figure 1-3 As shown, an ecological treatment system for livestock breeding sewage based on glass pumice 8 comprises a breeding farm 1, the sewage outlet of the breeding farm 1 is sequentially connected to a dry-wet separation tank 2, a sedimentation tank 3, a filtration tank 4, a glass pumice filter tank 5 and a water storage tank 6, the filtration tank 4 comprises a tank body 4.1, and a ceramsite filter material layer 4.2, a quartz sand filter material layer 4.3 and a pebble support layer 4.4 are sequentially arranged in the tank body 4.1 from top to bottom, the top water outlet of the sedimentation tank 3 is connected to the upper part of the tank body 4.1 through a pipeline, and a water collecting pipe 4.5 is arranged in the tank body 4.1, and the water collecting pipe 4.5 is located inside the pebble support layer 4.4, and the water collecting pipe 4.5 is located inside the pebble support layer 4.4. The outlet water of the water pipe 4.5 is connected to the water flow trough 7 outside the filter pool 4, and the water flow trough 7 is connected to the glass pumice filter tank 5. The glass pumice filter tank 5 includes a tank body 5.1, and the tank body 5.1 is filled with glass pumice 8. As a very good purification material, the physical properties of glass pumice made of 100% inorganic matter make it non-toxic, non-polluting, non-volatile, and will not produce any chemical reaction after long-term use, and it has stable properties. The glass pumice composed of dense pores also has the characteristics of filtering, adsorption, breeding microbial growth, biodegradation, enhancing water-dissolved oxygen, absorbing odors, inhibiting odors, and inhibiting blue-green algae in water.

[0024] In this embodiment, the breeding farm 1 includes a pen 1.1 and a drainage ditch 1.2 arranged on the periphery of the pen 1.1, and the drainage ditch 1.2 is connected to the dry-wet separation pool 2; the wall of the breeding farm 1 is made of glass light stone prefabricated bricks 1.1.1, and the extended area per gram of the glass light stone prefabricated bricks 1.1.1 is 10000cm, and the density specific gravity is 0.2-1g / cm3, which can not only reduce the noise inside the pen 1.1, but also use the dense pore characteristics of the glass light stone to absorb and eliminate the odor in the pen 1.1, thereby purifying the air of animal husbandry.

[0025] In this embodiment, the dry-wet separation tank 2 is a separation tank with a grid structure. The grid gap of the dry-wet separation tank 2 is 5-10 mm. The solid-liquid separation of the waste in the farm 1 is achieved through the grid, and the intercepted solid pollutants are transported out for treatment by manual or mechanical scooping.

[0026] In this embodiment, the sedimentation tank 3 is an inclined tube sedimentation tank 3.

[0027] In this embodiment, the length of the water trough 7 is 100m, and the bottom of the water trough 7 is paved with glass pumice 8. Aquatic plants 7.1 are planted in the water trough 7. The aquatic plants 7.1 include canna, iris, lotus and pennywort. When the water from the filter pool 4 flows through the water trough 7, the glass pumice 8 is used to enhance the filtering effect of pollutants. The aquatic plants 7.1 can not only effectively absorb harmful organic matter in the water, but also enhance the appearance of the device, thereby enhancing the environmental protection and ecological effect of the device.

[0028] In this embodiment, glass pumice 8 is laid on the bottom of the water reservoir 6 .

[0029] The principle of the present invention is:

[0030] After the aquaculture wastewater generated in the pen 1.1 flows into the dry-wet separation tank 2 through the drainage ditch 1.2, the impurities in the aquaculture wastewater are separated into solid and liquid, and the separated wastewater flows into the sedimentation tank 3 and the filtration tank 4 in turn for sedimentation and filtration respectively. At this time, the appearance of the wastewater is already clean and clear. When the wastewater passes through the hundred-meter-long water flow trough 7 and the glass light stone filter tank 5, the wastewater can be fully purified by utilizing the good adsorption characteristics of the glass light stone 8. Finally, the purified water is concentrated in the water reservoir 6 for storage. At the same time, since the bottom of the water reservoir 6 is also paved with a layer of glass light stone 8, the purified water body can be purified and maintained again to ensure that the water body after sewage treatment is at a higher water quality standard. This treatment system does not require the aid of external equipment and instruments, and greatly improves the environmental protection and cleaning performance of the device while ensuring the treatment effect.
