Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a bacteria culture device for sewage treatment. Background Art

[0002] Among the many sewage treatment methods, biological treatment is the most important sewage treatment process in the world because of its simple process, significant results, low cost, pure natural environmental protection, and no secondary pollution. Among them, the use of bacteria to purify sewage is a common operation. The main principle of sewage purification is based on the ability of bacteria to decompose organic matter in sewage. In an anaerobic environment, some bacteria (such as methanogens) can decompose organic matter through the fermentation process to produce methane gas, which can be used as a clean energy source. In an aerobic environment, bacteria can decompose organic matter into carbon dioxide and water. This process effectively purifies sewage. In addition, some bacteria can also decompose some organic matter in sewage and convert it into inorganic matter, further purifying the water.

[0003] However, the structures of the devices currently using bacteria and other microorganisms for sewage treatment are relatively complex. In the actual cultivation process, the number of bacterial culture devices is generally fixed, and the number of bacterial culture devices and the distance between two adjacent bacterial culture devices cannot be adjusted. When facing sewage treatment of different purities, due to the limited contact range between the bacterial culture devices and the sewage, it is very easy to have problems such as excessive bacterial flora or too few flora.

[0004] Since bacteria will multiply in large numbers during the sewage treatment process, the cultured bacteria need to be replaced in order to achieve a suitable sewage treatment effect and avoid large-scale bacterial reproduction affecting the water quality after decontamination. However, the actual operation of replacing the bacterial culture device is not very convenient and cannot be performed independently, resulting in a waste of culture resources. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a bacterial culture device for sewage treatment, which can adjust the number and spacing of bacterial culture devices according to the purity of sewage to solve the problem of mismatch between the number of bacterial cultures and the purity of sewage.

[0008] In the above-mentioned bacterial culture device for sewage treatment, a groove is arranged at the center of the biological disk, a turntable frame for driving the biological disk to rotate is installed inside the groove, and a flocculent biofilm is laid on the surface of the turntable frame.

[0009] In the above-mentioned bacterial culture device for sewage treatment, an adjustable bracket for installing biological disks is slidably provided on the sling, and the number of biological disks can be equipped by adjusting the gaps between the biological disks.

[0010] In the above-mentioned bacterial culture device for sewage treatment, a counterweight block is installed at the bottom of the sling to ensure that the biological tray will not tip over.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] A bacterial culture device for sewage treatment, such as Figures 1 to 3 As shown, it comprises an incubator 1 , the top of which is equipped with a box cover 2 , a plurality of cross beams 10 are arranged between the side walls at the top of the incubator, and a plurality of bacterial culture components are installed on the cross beams 10 .

[0020] The incubator 1 comprises a square frame 11 surrounded by a steel frame. Figure 2 As shown, removable transparent side panels 12 are installed between adjacent vertical steel frames constituting the frame 11 to facilitate observation of the degree of bacterial culture, a sealed bottom plate is installed between the bottom steel frames, the top steel frames are open, and the crossbeam 10 is installed between the steel frames on both sides of the top.

[0021] The bacterial culture assembly comprises a sling 3 mounted on a crossbeam 10 via a ring buckle 8, a plurality of circular biodisks 5 with adjustable gaps are mounted on the sling 3, and a flocculent biofilm is arranged on the biodisk 5, which can be used for breeding and culturing bacteria.

[0022] A groove is provided in the center of the bio-disc 5, and a turntable frame 9 is installed inside the groove to drive the bio-disc 5 to rotate. The flocculent biofilm is laid on the surface of the turntable frame 9, which can control the bio-disc 5 to react with microorganisms in the sewage to reproduce and cultivate bacteria.

[0023] A counterweight block 7 is installed at the bottom of the sling 3. The counterweight block 7 can compensate for the unbalanced force generated when the biological disk 5 rotates, thereby ensuring that the biological disk 5 will not tip over.

[0024] An adjustable bracket 4 for mounting a biological tray 5 is slidably provided on the sling 3. The number of biological trays can be selected according to the purity of the sewage by adjusting the position of the adjustable bracket 4.

[0025] A partition plate 6 is detachably mounted between the bacterial culture components on adjacent cross beams 10 inside the incubator 1. Figure 1 As shown, the partition plate 6 can separate the incubator 1 into two spaces that do not interfere with each other, making it easy to replace the bacterial culture components.

[0026] When in use, first determine the number of bio-disks 5 according to the purity of sewage, adjust the gap between adjacent adjustable brackets 4, and install the bio-disks, then install the counterweight 7 at the bottom of the sling 3, and then install the bacterial culture assembly on the beam 10 through the buckle 8, and finally rotate the turntable frame 9 to realize the rotation of the bio-disk 5, so that the sewage reacts with the flocculent biofilm on the surface of the bio-disk to culture bacteria.

[0027] During the rotation of the bio-disk, the flocculent biofilm will adsorb organic pollutants in the sewage and absorb dissolved oxygen in the water film outside the biofilm to decompose the organic matter. The microorganisms can reproduce themselves in this process and the sewage is continuously purified.

[0028] The cultivation situation inside the incubator can be observed through the transparent side panel. If the bacterial culture components need to be removed, the partition plate 6 is installed at a suitable position to isolate a group of bacterial culture components to be removed from other groups to form two spaces that do not interfere with each other. After draining the sewage, the biological disks are removed and collected separately, and then the above operation is repeated for installation.

[0029] The utility model provides a bacterial culture device for sewage treatment, which has a simple structure and is easy to operate. The number and spacing of biological discs can be adjusted by cooperating with slings and adjustable brackets, so the device can be suitable for sewage treatment with different purities, and the problem of excessive and scarce bacterial culture caused by the mismatch between the number of biological discs and the purity of sewage is reduced. The reproduction and cultivation of bacteria are well completed, and the bacterial culture components are separately isolated by arranging a partition plate, which makes it convenient to replace the bacterial culture components and improves the operating efficiency.
