Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically an experimental device for a denitrifying filter bed enhanced by denitrifying bacteria packing biofilm. Background Technology

[0002] The denitrifying filter apparatus enhanced with denitrifying bacteria biofilm mainly achieves denitrification by constructing a biofilm within the filter and utilizing denitrifying bacteria to reduce nitrogen sources (such as nitrates) in the water. Compared to traditional physical or chemical denitrification methods, denitrifying bacteria biofilm technology is a low-energy biological treatment method. Denitrification utilizes microbial metabolic processes, reducing dependence on external energy sources.

[0003] The current experimental device for denitrifying filter bed enhanced with denitrifying bacteria packing biofilm still has the following problems when in use: each part of the equipment is independent during the experiment, and multiple devices need to be connected during use, resulting in low portability. When testing various packing materials, it is not convenient to quickly replace the subsequent packing materials. Furthermore, when testing the biofilm strength, it is not possible to adjust the temperature according to the internal temperature or quickly change and adjust the material of the packing frame, which leads to a decrease in biofilm strength and easy detachment. Utility Model Content

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please refer to Figure 1-6An experimental device for denitrifying filter bed enhanced by denitrifying bacteria packing biofilm includes a base 1, a support frame 2 fixedly connected to the top of the base 1, a temperature control component 3 set on the support frame 2, two reaction columns 4 installed inside the temperature control component 3, a sealing cover 5 on the top of each of the two reaction columns 4, a raw water pump 6 fixedly connected to the rear end of the top of the base 1, and backwash pumps 7 fixedly connected to both sides of the top of the base 1.

[0026] Both reaction columns 4 are equipped with packing assemblies 8. Two wastewater collection tanks 9 corresponding to the reaction columns 4 are installed at the top front end of the base 1. The raw water pump 6 is fixedly connected to the two reaction columns 4, and the two reaction columns 4 are fixedly connected to the two corresponding backwash pumps 7. The top of both reaction columns 4 is fixedly connected to the backwash drain pipe 11, and the bottom of both reaction columns 4 is fixedly connected to the wastewater drain pipe 12. Solenoid valves 13 are installed on the two wastewater drain pipes 12, the backwash drain pipe 11, and the multiple connecting pipes 10.

[0027] The temperature control assembly 3 includes a heating frame 31 fixedly connected to the top of the support frame 2. A power supply 32 corresponding to the heating frame 31 is fixedly connected to the top center of the base 1. A controller 33 is installed on the top of the heating frame 31. Temperature sensors 34 penetrating the corresponding reaction column 4 are installed on both sides of the controller 33. Two temperature displays 35 are provided on the top of the controller 33. When backwashing to test the biofilm strength, the temperature sensors 34 monitor the internal temperature of the reaction column 4 in real time and display it through the temperature displays 35. The heating frame 31 can be activated by the power supply 32, thereby changing the internal temperature of the reaction column 4 and changing the strength of the biofilm by changing the temperature.

[0028] The heating frame 31 is provided with two heating rings, and the two reaction columns 4 are fixedly connected to the inner wall of the corresponding heating rings; so that the two heating rings can heat the two reaction columns 4, thereby changing their internal environment and giving the reaction columns 4 high installation stability.

[0029] Multiple sealing strips are installed on the inner walls of the two sealing caps 5, and all the sealing strips are tightly fitted to the outer wall of the corresponding reaction column 4; this ensures a high degree of sealing between the sealing caps 5 and the reaction column 4, thereby ensuring that the raw water and backwash water cannot leak during the experiment, thus guaranteeing the experimental results.

[0030] The packing assembly 8 includes mounting grooves 81 formed on both sides of the inner wall of the reaction column 4. A circular moving groove 82 is formed at the bottom of both mounting grooves 81. A locking groove 83 is formed on both sides of the top of the moving groove 82. Mounting plates 84 are slidably connected inside both moving grooves 82. A packing frame 85 is mounted at the bottom of both mounting plates 84. Two springs 86 are fixedly connected to the top of both mounting plates 84. Locking plates 87 are slidably connected inside both mounting grooves 81. Each locking plate 87 is connected to the other end of a corresponding spring 86. To replace the packing or packing frame 85, remove the sealing cap 5, then press the locking plate 87. The springs 86 are compressed until the locking plate 87 is pressed down into the moving groove 82. Then, rotate the mounting plate 84 until it is inside the mounting groove 81. Finally, remove the packing frame 85 upwards to replace the packing and the packing frame 85 itself. This assembly offers high portability and installation stability.

[0031] The bottom of the packing frame 85 has a porous structure, and the packing frame 85 is rotatably connected to the inner wall of the reaction column 4; this allows the packing frame 85 to serve as a packing carrier and a subsequent propagation carrier for microorganisms. The rotation between the packing frame 85 and the inner wall of the reaction column 4 facilitates quick disassembly.

[0032] The working principle of this utility model is as follows: First, remove the sealing cap 5, add the filler to be tested into the inside of the filler frame 85, then insert the two mounting plates 84 into the corresponding mounting slots 81, so that they fall into the moving slots 82, then press the clamping plate 87, at which time the spring 86 is compressed until the clamping plate 87 is pressed into the moving slots 82, then rotate the mounting plate 84 and the clamping plate 87 so that they are located inside the slots 83, and then release the clamping plate 87 to achieve fixation.

[0033] Next, culture medium is added to the inside of reaction column 4 for incubation. Then, the sealing cap 5 is covered. During the experiment, raw water is added to the inside of the two reaction columns 4 through the raw water pump 6. The denitrification reaction takes place inside the reaction column 4. After the reaction is completed, the wastewater is discharged into the wastewater collection tank 9 through the wastewater drain pipe 12 and controlled by the solenoid valve 13.

[0034] Subsequently, the reaction column 4 needs to be backwashed, and the strength of the biofilm can be tested at the same time. Two backwash pumps 7 are started, and water flows from bottom to top to backwash and test whether the biofilm is detached. When the strength of the biofilm is low, the internal environment of the reaction column 4 can be adjusted by the temperature control component 3, and the heating temperature of the heating rack 31 can be changed. The temperature is monitored by the temperature sensor 34 and displayed by the temperature display 35. When changing the environment still cannot improve the strength of the biofilm, the material of the packing rack 85 needs to be changed to change the strength of the biofilm. This process can also replace the packing and test the denitrification effect of other packings.

[0035] Remove the sealing cap 5, and similarly, remove the packing rack 85. Then, replace the material of the packing rack 85 and the packing to be tested, and then install it into the inside of the reaction column 4. Repeat the above operations for subsequent tests.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
