Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency biological contact oxidation device for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the removal or transformation of harmful substances in wastewater through various means such as physical, chemical, and biological methods, in order to achieve the purpose of water reuse or safe discharge. Depending on the treatment objectives and the degree of pollution, wastewater treatment can generally be divided into the following steps: physical treatment, biological treatment, advanced treatment, sludge treatment and disposal, and wastewater reuse.

[0003] One key aspect of biological contact oxidation treatment technology is filling the tank with packing material. Oxygenated wastewater completely submerges the packing material and flows through it at a controlled rate. A biofilm forms on the packing material, allowing for extensive contact between the wastewater and the biofilm. Through the metabolic activity of the microorganisms on the biofilm, organic pollutants are removed, and the wastewater is purified. Therefore, biological contact oxidation treatment technology is also known as a "submerged biological filter." Another key aspect of biological contact oxidation treatment technology is the use of the same aeration method as in aeration tanks. This provides the microorganisms with the necessary oxygen and also acts as a mixer and mixer. Thus, this technology is equivalent to filling the aeration tank with packing material for the microorganisms to inhabit; therefore, it is also called the "contact aeration method."

[0004] As mentioned above, biological contact oxidation is a biological treatment technology that falls between activated sludge and biological filters. It can also be described as a biofilm method with characteristics of activated sludge, combining the advantages of both. Therefore, it has received considerable attention in the field of wastewater treatment engineering.

[0005] Existing combined packing materials are all fixed inside the biological filter using a fixed structure, making them impossible to disassemble. After prolonged use, the combined packing materials become damaged, and the disassembly process is complex, increasing usage costs. Furthermore, individual disassembly is not possible, resulting in low practicality. No solutions have yet been proposed to address these technical problems. Utility Model Content

[0006] In view of the problems in related technologies, this utility model proposes a high-efficiency biological contact oxidation device for sewage treatment to overcome the above-mentioned technical problems existing in the existing related technologies. The purpose of this utility model is to facilitate the installation and disassembly of the combined packing material, which is beneficial to the later maintenance and replacement, improves the overall practicality, and reduces the cost of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency biological contact oxidation device for wastewater treatment, comprising a biological filter, with support plates on both sides of the biological filter, and several pillars between the two support plates. The bottom of each pillar is connected to several vertical columns via a connecting mechanism. Several combined packing materials are mounted on the vertical columns. The connecting mechanism includes a spring, a movable block, and a locking block. Several openings are formed on the outer surface of one top end of each vertical column. The two ends of the spring are fixedly connected to the openings and the movable block, respectively. The locking block is fixedly installed on the top end of the movable block. A locking groove matching the locking block is formed at the bottom of the pillar. The combined packing materials are mounted on the vertical columns via an installation mechanism, which includes a spring and a limiting block. Grooves are formed on both sides of each vertical column. The two ends of the spring are connected to the grooves and the limiting block, respectively. A limiting groove matching the limiting block is formed on the combined packing materials.

[0008] Preferably, fixing blocks are installed on both sides of the bottom of the support column, and the top of the support plate has several fixing grooves that match the fixing blocks.

[0009] Preferably, the bottom of the column is fixedly connected to an installation block, and the bottom of the biofilter has several installation slots that match the installation block.

[0010] Preferably, the top end of the card block is inclined at an angle of 15° to 45°.

[0011] Preferably, the end of the limiting block away from the second spring is inclined, with an inclination angle of 15° to 45°.

[0012] Preferably, the bottom of the movable block is connected to a slider, and one end of the bottom of the opening is provided with a groove that matches the slider. The movable block and the locking block are an integrated structure.

[0013] Preferably, the spacing between two adjacent support pillars is 20cm.

[0014] Preferably, the spacing between two adjacent composite packing materials is 8 cm.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) This utility model is a high-efficiency biological contact oxidation device for sewage treatment. By setting a connection mechanism, when installing the column, the card block at one end of the top of the column is inserted into the card slot of the column. After insertion, under the action of spring one, the card block on the movable block is engaged in the card slot, thereby achieving fixation. When disassembling, the movable blocks on both sides are pressed manually, and spring one is compressed, so the card block on the column can be pulled out. This makes it convenient to install and disassemble multiple combined packings on the column as a whole. It is highly convenient and practical.

[0017] (2) This utility model is a high-efficiency biological contact oxidation device for sewage treatment. By setting an installation mechanism, when installing the combined packing, the combined packing is sleeved on the column. When the limiting block and the limiting groove are on the same horizontal line, the spring two will abut the limiting block in the limiting groove, which can fix the combined packing. It is convenient to install and disassemble individual combined packings. The disassembly operation steps are simple and reduce the cost of use. Attached Figure Description

Support plates 2 are provided on both sides of the biological filter 1, specifically, the support plates 2 serve as support pillars 3. Several pillars 3 are arranged between two support plates 2, specifically, the several pillars 3 are arranged horizontally and parallelly. Several columns 4 are connected to the bottom of each pillar 3 via a connecting mechanism, specifically, five columns 4 are provided at the bottom of each pillar 3. Several combined packing materials 8 are provided on each column 4, specifically, twelve combined packing materials 8 are provided on each column 4. The combined packing materials 8 adopt existing technology, and their function is to provide a surface for biofilm attachment and promote biofilm growth and development. The surface of the combined packing materials typically has special physical and chemical properties to help microorganisms attach to their surface. The diameter of the combined packing materials 8 is 15 cm. The connecting mechanism includes a spring 5, a movable block 6, and a locking block 7. Several openings are opened on the outer surface of one end of the top of each column 4. Both ends are fixedly connected to the opening and the movable block 6 respectively. The locking block 7 is fixedly installed at the top end of the movable block 6. The bottom of the support column 3 has a locking groove that matches the locking block 7. Specifically, when installing the column 4, the locking block 7 at the top end of the column 4 is inserted into the locking groove of the support column 3. After insertion, under the action of the spring-5, the locking block 7 on the movable block 6 is locked in the locking groove, thereby achieving fixation. When disassembling, manually press the movable blocks 6 on both sides, the spring-5 is compressed, and the locking block 7 on the column 4 can be pulled out; combined packing The 8 is installed on the column 4 by an installation mechanism, which includes a second spring 9 and a limiting block 10. Grooves 11 are provided on both sides of the column 4. The two ends of the second spring 9 are connected to the grooves 11 and the limiting block 10 respectively. The combined packing 8 is provided with a limiting groove that matches the limiting block 10. Specifically, when installing the combined packing 8, the combined packing 8 is fitted onto the column 4. When the limiting block 10 and the limiting groove are on the same horizontal line, the second spring 9 abuts the limiting block 10 in the limiting groove, thereby fixing the combined packing 8.

[0025] Please see Figure 1 As shown, furthermore, fixing blocks 12 are installed on both sides of the bottom of the support column 3, and several fixing grooves matching the fixing blocks 12 are opened on the top of the support plate 2.

[0026] In this embodiment, the fixing block 12 serves to position the support column 3 and prevent the support column 3 from sliding.

[0027] Please see Figure 1 As shown, furthermore, the bottom of the column 4 is fixedly connected to the mounting block 13, and the bottom of the biological filter 1 is provided with several mounting grooves that match the mounting block 13.

[0028] In this embodiment, the mounting block 13 and the mounting groove are used to position the column 4.

[0029] Please see Figure 2 As shown, the top end of the card block 7 is tilted at an angle of 15° to 45°.

[0030] In this embodiment, the tilt angle is 45° to improve the efficiency of the insertion.

[0031] Please see Figure 3 As shown, furthermore, the end of the limiting block 10 away from the spring 9 is inclined, with an inclination angle of 15° to 45°.

[0032] In this embodiment, the tilt angle is 15°, which facilitates the installation and disassembly of the combined packing 8.

[0033] Please see Figure 2 As shown, the bottom of the movable block 6 is connected to a slider, and a groove matching the slider is provided at one end of the bottom of the opening. The movable block 6 and the locking block 7 are an integrated structure.

[0034] In this embodiment, the movable block 6 moves the slider within the groove, effectively improving the stability of the movable block 6's movement.

[0035] Furthermore, the distance between two adjacent support pillars 3 is 20cm.

[0036] Furthermore, the spacing between two adjacent combined packing materials 8 is 8 cm.

[0037] The working principle of this utility model:

[0038] First, several combined packing blocks 8 are installed onto the column 4 using the installation mechanism. Then, the combined packing blocks 8 are sequentially fitted onto the column 4. When the limiting block 10 and the limiting groove are on the same horizontal line, the spring 9 holds the limiting block 10 against the limiting groove, thus fixing the combined packing blocks 8. Next, the column 4 is installed onto the support column 3 using the connecting mechanism. The locking block 7 at the top end of the column 4 is inserted into the locking groove of the support column 3. After insertion, the locking block 7 on the movable block 6 is engaged in the locking groove under the action of the spring 5, thus achieving fixation. Finally, the fixing blocks 12 at both ends of the bottom of the support column 3 are inserted into the fixing grooves of the support plate 2 to complete the installation.

[0039] This invention facilitates the installation and disassembly of the combined packing 8, which is beneficial for later maintenance and replacement, improves overall practicality, and reduces the cost of use.
