Description

Technical Field

[0001] The utility model relates to the field of water purification, in particular to a microorganism slow-release device. Background Art

[0002] Large-scale equipment for treating high-concentration sewage is no longer suitable for the current water treatment needs, but there are still some "leakage" problems in the current pipeline network. The stability of the water ecosystem requires certain water treatment equipment for auxiliary purification, so small-scale integrated water treatment equipment floating on the water surface came into being.

[0003] There are currently a variety of small-scale purification devices, such as patent CN 202021371784.6, which discloses an integrated in-situ remediation device, which describes the use of microbial agents combined with fountains to release microorganisms into the water body, but since the microorganisms have no carriers to attach to, they are easily lost with the flow of the water body. Other equipment that mainly uses purification fillers has a long period of filler biofilm formation due to the lack of microorganisms, making it difficult to achieve the expected water purification effect. For example, patent CN 202220790788.0 discloses a biochemical reactor for water treatment, which describes the installation of a microbial agent package in a device with purification fillers as the main body, and combines aeration to form a purification device, but the microbial agent package is located in the middle of the equipment, which is difficult to replace, and there is no carbon source required for the growth and reproduction of microorganisms. There are two layers of support plates in the middle of the filler to separate the filler, which is not conducive to the upward diffusion of aeration, and the upper filler is difficult to rinse. At present, this type of integrated equipment also lacks integration with the landscape, and it is difficult to meet the requirements of purification and landscape integration.

[0004] In summary, there is an urgent need for a device that can purify water and can form a stable biofilm to purify water. Utility Model Content

[0044] Embodiment 1

[0045] This embodiment provides a microorganism slow-release device, see Figure 1 and Figure 2, the microbial sustained-release device includes a first filling bin 1, a second filling bin 2 and a float 3. The first filling bin 1 includes a first filling bin body 11 and a first filling cavity 12 which is arranged in the first filling bin body 11 and is open upward. The first filling cavity 12 is configured to place immobilized microorganisms and carbon sources, and the provision of the carbon source is conducive to maintaining the activity of the microorganisms. Specifically, the volume ratio of the immobilized microorganisms and the carbon source in the first filling cavity 12 is 1 to 3:0.5 to 1, and the preferred ratio is 2:1. In addition, a plurality of first hollows 13 are provided on the side wall of the first filling bin body 11. Specifically, the shape of the first hollow 13 is a herringbone hollow or a plum blossom hollow. Preferably, the shape of the first hollow 13 is a herringbone hollow. The float 3 is arranged outside the second filling bin 2.

[0046] It is worth mentioning that, continue to refer to Figure 1 and Figure 2 , the side wall of the first filling warehouse body 11 is relatively thin, therefore, the side wall of the first filling warehouse body 11 is a general term, and its meaning includes the inner wall of the first filling warehouse body 11 and the outer wall of the first filling warehouse body 11. Specifically, the radius of the first filling warehouse body 11 is 200 to 400 mm, preferably 300 mm. It should be noted here that the cross-sectional shape of the first filling warehouse body is generally circular. In addition, the first hollow 13 should penetrate the side wall of the first filling warehouse body 11, so that the microorganisms and carbon sources in the first filling chamber 12 can pass through the side wall of the first filling warehouse body 11, and then flow out of the first filling warehouse body 11.

[0047] Continue reading Figure 1 and Figure 2 , the second filling bin 2 includes a second filling bin body 21 and a second filling cavity 22 which is arranged in the second filling bin body 21 and is open upward, and the first filling bin 1 is arranged in the second filling cavity 22. The side wall of the second filling bin body 21 is provided for placing fillers. Specifically, the filler in the side wall of the second filling bin body 21 is selected from any one of glass pumice, light ceramic particles or zeolite. More specifically, the ratio of glass pumice, light ceramic particles and zeolite in the side wall of the second filling bin body 21 is 1-3:1-2:0.5-1, and the preferred ratio is 3:2:1. In addition, a plurality of second hollows 23 are provided on the inner wall of the second filling bin body 21. Specifically, the shape of the second hollow 23 is a herringbone hollow or a plum blossom hollow. Preferably, the shape of the second hollow 23 is a herringbone hollow. It is worth noting that the side wall of the second filling bin body 21 is thicker, so the inner diameter and outer diameter of the second filling bin body 21 are distinguished separately. The inner diameter of the second filling silo 21 is 200-400 mm, preferably 300 mm. The radius of the second filling silo 21, that is, the outer diameter, is 900-1100 mm, preferably 1000 mm. In addition, the outer wall of the second filling silo 21 is made of glass fiber reinforced plastic.

[0048] In a preferred embodiment, the first filling bin 1 is configured to be a pull-up type, and a handle is provided on the top of the first filling bin 1, so that the operator can take out the first filling bin 1 and replace the immobilized microorganisms and carbon sources in the first filling cavity 12, which provides convenience for the replacement of slow-release microorganisms and fillers. In addition, the first filling cavity 12 is provided with a cover 14 for closing the first filling cavity 12, and the cover 14 can prevent fallen leaves, dust and other debris from entering the first filling cavity 12, thereby ensuring the stable operation of the immobilized microorganisms and carbon sources in the first filling cavity 12. At the same time, generally speaking, landscape lamps are provided on the cover 14, so that the device also has the function of landscape display. Alternatively, a solar panel can be provided on the cover 14 to convert solar energy into electrical energy and supply it to the power system of the device.

[0049] See also Figure 1 and Figure 2 , and also includes an aeration device 4, the aeration device 4 includes an aeration main pipe 41 and a plurality of aeration short pipes 42, the aeration main pipe 41 is arranged below the side wall of the second filling silo 21, and the aeration main pipe 41 is externally connected to an aeration pump. Figure 1 and Figure 2 Each aeration short tube 42 includes a short tube air inlet end 421 and a short tube aeration end 422. The short tube air inlet end 421 is connected to the aeration main pipe 41, and the short tube aeration end 422 is arranged in the side wall of the second filling silo 21. It is worth noting that the aeration short tube 42 introduces oxygen into the side wall of the second filling silo 21, so that a dissolved oxygen environment is formed in the side wall of the second filling silo 21, so that microorganisms can better purify the water body. In addition, the aeration short tube 42 can be used as a backwash for the filler in the side wall of the second filling silo 21 to prevent the filler from being blocked.

[0050] In one specific embodiment, see Figure 1 and Figure 2 The aeration device 4 also includes a plurality of long aeration tubes 43, each of which includes a long tube air inlet end 431 and a long tube aeration end 432. The long tube air inlet end 431 is connected to the aeration main pipe 41, and the long tube aeration end 432 passes through the side wall of the second filling silo 21 from bottom to top and is exposed above the second filling silo 22. Specifically, a plurality of fine holes are provided on the aeration long tube 43, and a part of the water in the aeration long tube 43 flows into the side wall of the second filling silo 21 through the fine holes, and the other part is sprayed out of the water surface through the long tube aeration end 432 to form a fountain. The arrangement of the fine holes on the above-mentioned aeration long tube 43 enables the aeration long tube 43 to pass the water into the side wall of the second filling silo 21 while the fountain is formed, so that the oxygen content in the side wall of the second filling silo 21 increases, thereby improving the purification capacity of the device.

[0051] In addition, it is worth noting that nozzles may be provided on the short tube aeration end 422 and the long tube aeration end 432. The nozzles can make the water flow out evenly. For the short tube aeration end 422, the nozzles can make the water entering the side wall of the second filling bin 21 more evenly. For the long tube aeration end 432, the nozzles can further enhance the fountain effect.

[0052] In a preferred embodiment, see Figure 1 The aeration main pipe 41 is annularly arranged below the side wall of the second filling silo 21, and the aeration short pipes 42 and the aeration long pipes 43 are arranged at intervals. In a supplementary embodiment, the number of the aeration short pipes 42 and the aeration long pipes 43 are both 6 to 10. Preferably, the number of the aeration short pipes 42 and the aeration long pipes 43 are both 8.

[0053] Here, it is explained in detail how the device performs slow release of water. First, the immobilized microorganisms and carbon sources in the first filling chamber 12 will pass through the first hollow 13 on the first filling silo wall 12 and the second hollow 23 on the inner wall of the second filling silo wall 22 to enter the second filling silo wall 22, and form a multi-layer biofilm in the second filling silo wall 22. Secondly, the water enters the second filling silo wall 22 from the bottom of the second filling silo wall 22 through the aeration short tube 42. At this time, the filler in the second filling silo wall 22 hinders the flow of the water, slows down the flow rate of the water, and increases the time the water stays in the second filling silo wall 22, so that the biofilm in the second filling silo wall 22 can fully purify the water. Subsequently, the purified water flows out from the top of the second filling silo wall 22.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
