Description

Technical Field

[0001] The utility model relates to the technical field of fixed bacterial strain equipment, in particular to a movable fixed bacterial strain equipment. Background Art

[0002] Water pollution is a phenomenon caused by harmful substances in water bodies exceeding the environmental capacity due to human activities and natural factors. Water pollution has a serious impact on human health and the ecological environment, so effective treatment measures are needed to solve the water pollution problem. Bioaugmentation technology, as a bioremediation method, has been widely used in water pollution control due to its high efficiency, economy and environmental protection.

[0003] Biological treatment technology utilizes the ecological functions and metabolic characteristics of microbial strains to efficiently degrade various pollutants. Microbial strains have strong degradation capabilities and can decompose pollutants into harmless or low-toxic substances, thereby effectively reducing the degree of harm of pollutants to the environment. Moreover, biological treatment technology has a broad-spectrum degradation effect on a variety of pollutants, and the operation is relatively simple. It only requires the introduction of suitable microbial strains and the provision of suitable habitat conditions to achieve the degradation of pollutants through microbial strains.

[0004] The conventional utilization mode of biological treatment is to directly introduce specific biological populations to degrade pollutants, such as activated sludge method or biofilm method. However, the method of directly adding bacteria or sludge requires a certain amount of culture or biofilm growth time, which is usually relatively long.

[0005] The immobilization application mode refers to fixing the biological population on a specific carrier to form an immobilized biological community to degrade pollutants. In the immobilization application mode, the biological population is fixed on a porous carrier, fiber material, etc. to form a biofilm or biological particles. This form of immobilization can increase the area and time of contact between the biological population and the pollutants and improve the degradation efficiency. At the same time, the immobilized biological community also has good stability and can better adapt to complex water environments. The advantage of the immobilized biological community is that it can continuously degrade pollutants in the water body and is not easily affected by the external environment.

[0006] There are many types of carrier materials for immobilized microbial technology. Currently, the commonly used immobilized carrier materials at home and abroad mainly include three categories: inorganic carrier materials (such as activated carbon, silica, etc.), organic polymer materials (such as sodium alginate, agar, polyvinyl alcohol, etc.), and hybrid materials. The immobilized carriers prepared by these three types of materials are granular and are usually directly used in biochemical pools or box equipment. The immobilized carriers prepared by the above three materials are used to load the bacteria to form immobilized bacteria. Although such immobilized bacteria increase the number of bacteria to a certain extent and reduce the culture or biofilm time compared to directly adding sludge or bacteria, the immobilized bacteria are difficult to fully contact with the pollutants in the sewage during application. There are also problems such as the immobilized bacteria are easy to lose or block the equipment. Utility Model Content

[0023] Specifically, the net bag 400 is arranged in the shell 100, and the surface of the net bag 400 has a plurality of meshes 420, and the shape of the net bag 400 is cylindrical; by using the net bag 400 to place the granular immobilized bacteria, the cylindrical net bag 400 can increase the contact area between the sewage and the immobilized bacteria, and at the same time, the loss of the immobilized bacteria can be reduced through the net bag 400. The suction pump 500 is arranged on the outside of the cover plate 200, and the suction pump 500 is connected with the cavity 110 in the shell 100 through the pipe 510. The suction pump 500 can pump water and absorb water from the cavity 110 in the shell 100, that is, the suction pump 500 has the ability of two-way water flow, and when the immobilized bacteria block the pipeline of the equipment, the pipeline of the equipment can be dredged by repeatedly pumping water or absorbing water from the cavity 110 in the shell 100, thereby solving the problem of the immobilized bacteria blocking the pipeline. The present invention provides a movable immobilized bacteria device 10, which allows the immobilized bacteria to fully contact with sewage, so that the pollutants in the sewage can be better and faster degraded, and the loss of the immobilized bacteria can be effectively reduced by setting the net bag 400; at the same time, the suction pump 500 is also provided, and the cavity 110 in the shell 100 is repeatedly pumped or absorbed to solve the problem of the immobilized bacteria blocking the equipment pipeline.

[0024] In this embodiment, the movable immobilized bacteria device 10 is directly placed on the bottom of the sewage pool. The movable immobilized bacteria device 10 is immersed in sewage. The sewage enters the cavity 110 through the hollow membrane 300 and flows into the net bag 400.

[0025] In this embodiment, the net bag 400 is detachably arranged on the cover plate 200. By removing the hollow film 300 from the housing 100 and then removing the net bag 400 from the cover plate 200, the immobilized bacteria in the net bag 400 can be added or replaced.

[0026] In this embodiment, the hollow membrane 300 is arranged in the water inlet 120 at the first end of the shell 100. The hollow membrane 300 has a through hole (not shown in the figure). The through hole is used for sewage to pass through, and the hollow membrane 300 is used to filter the sewage to prevent large pieces of sediment in the sewage from entering the movable immobilized bacterial strain device 10, thereby avoiding large pieces of sediment from clogging the movable immobilized bacterial strain device 10.

When the connecting portion 410 is connected to the protrusion 220, each of the buckles is engaged in one of the slots. Specifically, through the above arrangement, when the net bag 400 needs to be installed on the cover plate 200, it is only necessary to align the buckles of the connecting portion 410 with the slots on the protrusion 220 one by one, so that the net bag 400 can be quickly installed on the cover plate 200. When removing, it is only necessary to remove the buckles of the connecting portion 410 from the slots on the protrusion 220 to complete the removal of the net bag 400 from the cover plate 200.

By using the above-mentioned threaded screw connection method, the net bag 400 can be easily removed or installed on the cover plate 200.

[0030] In order to reduce the loss of the immobilized bacteria from the net bag 400, in one embodiment, Figure 1 As shown, a filter screen 211 is disposed in the drainage hole 210. Specifically, the filter screen 211 can prevent the immobilized bacteria particles that are not completely dissolved from being lost from the drainage hole 210, thereby effectively reducing the loss of the immobilized bacteria from the net bag 400.

[0031] In one embodiment, the filter 211 has a plurality of meshes (not shown), and the aperture of the mesh 420 is equal to the aperture of the mesh. Specifically, the aperture of the mesh on the filter 211 is equal to the aperture of the mesh 420 on the net bag 400, so that the immobilized bacteria that are not completely dissolved can be kept in the net bag 400, reducing the loss of the immobilized bacteria.

[0032] In order to stably place the movable immobilized bacterial strain device 10 on the bottom of the pollution pool, in one embodiment, Figure 1 As shown, a support leg 600 is disposed outside the housing 100, and the support leg 600 is used to support the housing 100 and the suction pump 500. Specifically, the support leg 600 is disposed on the side of the housing 100, so that the movable immobilized bacterial strain device 10 can be placed flat on the bottom of the sewage pool through the support of the support leg 600.

[0033] In order to facilitate observation of the immobilized bacteria in the housing 100, in one embodiment, the housing 100 is made of transparent plastic. Specifically, the housing 100 is made of transparent plastic, which facilitates direct observation of the immobilized bacteria in the housing 100, thereby quickly determining whether the immobilized bacteria need to be added or replaced.

[0034] In this embodiment, the transparent plastic is corrosion-resistant and acid- and alkali-resistant, thereby ensuring that the shell of the movable immobilized bacterial strain device 10 can be placed in a sewage pool for a long time, is not easily corroded by various pollutants, and has a long practical life.
