Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical wastewater treatment technology, and in particular to a tubular pharmaceutical wastewater treatment experimental device. Background Technology

[0002] Currently, the treatment methods for pharmaceutical wastewater mainly include adsorption, membrane separation, coagulation and sedimentation, advanced oxidation, and biological methods. However, in adsorption, activated carbon is costly and difficult to recycle and regenerate; membrane separation technology suffers from membrane fouling; coagulation and sedimentation requires large amounts of coagulants and is not very efficient at removing dissolved substances from wastewater; advanced oxidation methods do not completely degrade organic matter and have low mineralization rates of degradation products; and biological methods require pretreatment of wastewater to remove components harmful to organisms.

[0003] Photocatalytic oxidation technology, as a novel water treatment technology, mainly utilizes ultraviolet light to irradiate photocatalysts to generate active oxygen, which decomposes most organic matter and removes some inorganic matter. This method does not produce secondary pollution and decomposes thoroughly, making it an environmentally friendly treatment technology. How to effectively utilize the spatial structure of photocatalytic devices and enhance their treatment efficiency is a key issue that needs to be considered in the field of photocatalytic treatment of pharmaceutical wastewater. At present, it is difficult for a single process to meet the requirements of deep treatment of fermentation pharmaceutical wastewater and to achieve stable discharge standards. In order to enable pharmaceutical wastewater to meet discharge standards, in most cases, it is still necessary to seek a combination of multiple treatment processes.

[0004] Currently, experimental devices for treating pharmaceutical wastewater combining photocatalysis and adsorption have emerged, such as the technical solution disclosed in Chinese Utility Model Patent No. CN202310534203.8. This device uses photocatalytic oxidation combined with adsorption decomposition to treat pharmaceutical wastewater and reduce its COD. However, existing experimental devices combining catalysis and adsorption suffer from low versatility. Different experimental devices need to be designed for different experiments, resulting in high experimental costs. Furthermore, since many situations need to be addressed in the experiments, it is difficult to solve these problems if the designed experimental device has a closed structure, requiring the fabrication of additional devices to solve these issues. Therefore, it is necessary to improve this approach. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tubular pharmaceutical wastewater treatment experimental device that is highly versatile and occupies a small area, in order to address the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tubular pharmaceutical wastewater treatment experimental device, characterized in that: it includes a frame, a water tank is installed at one end of the frame and a water storage block is installed at the other end, the water tank is provided with at least one water storage chamber, an inlet connector is installed on one side of the water tank and is connected to the water storage chamber, an outlet connector is installed on one side of the water storage block and is connected to the interior of the water storage block, at least two test tubes are installed between the water tank and the water storage block and are respectively connected to the water tank and the water storage block, each test tube is connected to a water storage chamber, an ultraviolet generator is installed in the test tube, a titanium wire mesh is set inside the test tube and a catalyst module is loaded, and a voltage regulator electrically connected to the ultraviolet generator is installed on the side of the frame near the water tank.

[0007] Using the above technical solution, the water tank and the water storage block are set on the same vertical plane, and both are connected to one end of the test tube. During the experiment, pharmaceutical wastewater is introduced into the water storage chamber through the inlet connection and then into the test tube. The voltage regulator controls the ultraviolet generator in the test tube to turn on. The test tube is equipped with a titanium wire mesh and loaded with a catalyst module to perform photocatalytic oxidation on the pharmaceutical wastewater in the test tube. After the preset experimental time is reached, the pharmaceutical wastewater is extracted from the outlet connection of the water storage block. When more than one set of pharmaceutical wastewater needs to be tested, another set of pharmaceutical wastewater is introduced into another water storage chamber and introduced into the corresponding test tube for testing. The ultraviolet generator in the test tube is turned on, and the preset experimental time is waited for. After the test is completed, the wastewater is extracted. This solution can conduct multiple sets of pharmaceutical wastewater experiments at once, and it is small in size, highly versatile and low in cost.

[0008] The aforementioned tubular pharmaceutical wastewater treatment test equipment can be further configured such that: an installation plate module is provided in the water tank, the installation plate module includes an installation plate, the installation plate has an installation hole with an inner diameter consistent with the outer diameter of the test tube, and the two sides of the installation plate are fixedly connected to the inner wall of the water tank through connecting plates.

[0009] By adopting the above technical solution, an installation plate module is set in the water tank, and the end of the test tube located in the water storage chamber is fixed by the installation plate module to ensure the stability of the device.

[0010] The aforementioned tubular pharmaceutical wastewater treatment experimental device can be further configured such that: the mounting plate is provided with connecting ears on both sides, the connecting plate is L-shaped and one end is fixedly connected to the connecting ear and the other end is fixedly connected to the inner wall of the water tank, and the mounting plate is provided with guide strips that are perpendicular to the mounting plate at 90°.

[0011] Using the above technical solution, the width of the mounting plate after setting the guide strip is adapted to the width of the water storage cavity. By setting the guide strip, the mounting plate can be guided when placed in the water storage cavity, which can prevent scratching the inner wall of the water storage cavity and improve assembly efficiency.

[0012] The aforementioned tubular pharmaceutical wastewater treatment test equipment can be further configured as follows: the number of test tubes is five, the water tank is provided with a partition baffle that divides the inside of the water tank into five water storage chambers, each test tube is located in an independent water storage chamber, and the outside of the water tank is provided with a water inlet connection joint that is individually connected to each water storage chamber.

[0013] By adopting the above technical solution, the water tank is divided into five independent water storage chambers by a partition baffle. A test tube is installed in each water storage chamber. Then, by setting up a separate water inlet connector on the water tank that is connected to each water storage chamber, a water tank that can test 5 groups of pharmaceutical wastewater at the same time is obtained. Different components of pharmaceutical wastewater can be tested in each test tube. Each water inlet connector is connected to different components of pharmaceutical wastewater, further improving versatility.

[0014] The aforementioned tubular pharmaceutical wastewater treatment test equipment can be further configured such that: a stainless steel support tube is installed inside the test tube, the stainless steel support tube has multiple windows opened in the circumference, and the titanium wire mesh covers the outer circumference of the stainless steel support tube.

[0015] Using the above technical solution, simply placing titanium wire mesh inside the test tube results in uneven distribution of the titanium wire mesh due to the buoyancy of the water. Therefore, a stainless steel support tube is installed, and windows are opened on the stainless steel support tube to maximize the amount of pharmaceutical wastewater that can enter the test tube. By wrapping the titanium wire mesh around the surface of the stainless steel support tube, and further fixing the titanium wire mesh to the surface of the stainless steel support tube with fixing devices such as cable ties, the pharmaceutical wastewater located in all parts of the test tube can be evenly exposed to ultraviolet light and photocatalytic oxidation during photocatalytic oxidation, thereby improving the stability of the experiment.

[0016] The aforementioned tubular pharmaceutical wastewater treatment test equipment can be further configured such that: the ultraviolet generator is a waterproof ultraviolet lamp, one end of the waterproof ultraviolet lamp located in the water storage chamber is a terminal, the terminal is connected to a voltage regulator through a wire, and the number of voltage regulators is the same as the number of waterproof ultraviolet lamps.

[0017] Using the above technical solution, the ultraviolet lamp can generate ozone, and the ozone can undergo a photocatalytic oxidation reaction with the titanium wire mesh and the catalytic module supported on the titanium wire mesh. At the same time, the catalytic module can also adsorb pharmaceutical wastewater. The specific catalytic module can be set as a titanium dioxide catalyst.

[0018] The advantages of this utility model are: strong versatility, multiple sets of tests can be carried out at the same time, small footprint and simple structure. Attached Figure Description

[0027] See Figures 1 to 8 As shown:

[0028] Example 1: A tubular pharmaceutical wastewater treatment experimental device includes a frame 1, with a water tank 2 installed at one end and a water storage block 3 installed at the other end. The water tank 2 has at least one water storage cavity 21. A water inlet connector 4 is installed on one side of the water tank 2, which is connected to the water storage cavity 21. A water outlet connector 5 is installed on one side of the water storage block 3, which is connected to the interior of the water storage block 3. At least two test pipes 6 are installed between the water tank 2 and the water storage block 3, which are respectively connected to the water tank 2 and the water storage block 3. Each test pipe 6 is connected to a water storage cavity 21. An ultraviolet generator 7 is installed in the test pipe 6. A titanium wire mesh (not shown in the figure) is installed inside the test pipe 6 and a catalyst module is loaded. A voltage regulator 9, which is electrically connected to the ultraviolet generator 7, is installed on the side of the frame 1 near the water tank 2.

[0029] This design places the water tank and the water storage block on the same vertical plane, each connected to one end of the test tube. During the experiment, pharmaceutical wastewater is introduced into the water storage chamber through the inlet connector and then into the test tube. A voltage regulator controls the ultraviolet generator in the test tube to turn on. The test tube is equipped with a titanium wire mesh and a catalyst module, which performs photocatalytic oxidation on the pharmaceutical wastewater. After the preset experimental time is reached, the pharmaceutical wastewater is extracted from the outlet connector of the water storage block. When more than one set of pharmaceutical wastewater needs to be tested, another set of pharmaceutical wastewater is introduced into another water storage chamber and then introduced into the corresponding test tube for testing. The ultraviolet generator in the test tube is turned on, and the preset experimental time is waited for. After the test is completed, the wastewater is extracted. This design can conduct multiple sets of pharmaceutical wastewater experiments at once, and it is small in size, highly versatile, and low in cost.

[0030] The water tank 2 is equipped with an installation plate module, which includes an installation plate 31. The installation plate 31 has an installation hole 311 with an inner diameter that is the same as the outer diameter of the test tube 6. The two sides of the installation plate 31 are fixedly connected to the inner wall of the water tank 2 through connecting plates 32.

[0031] An installation plate module is installed in the water tank 2. The end of the test tube located in the water storage chamber 21 is fixed by the installation plate module to ensure the stability of the device.

[0032] The mounting plate 31 has connecting ears 312 on both sides. The connecting plate 311 is L-shaped and one end is fixedly connected to the connecting ear 312 while the other end is fixedly connected to the inner wall of the water tank 2. The mounting plate 31 is provided with a guide strip 33 that is perpendicular to the mounting plate 31 at 90°.

[0033] The width of the mounting plate 31 after the guide strip 33 is set is adapted to the width of the water storage cavity 21. By setting the guide strip 33, the mounting plate 31 can be guided when it is placed in the water storage cavity 21, which can prevent scratching the inner wall of the water storage cavity 21 and improve assembly efficiency.

[0034] The width of the connecting ear 312 is smaller than the width of the mounting plate 31, and it is provided with two connecting holes 3121. One end of the connecting plate 311 is provided with a second connecting hole 3111 at the corresponding position of the connecting hole 3121. The connecting hole 3121 is connected to the second connecting hole 3111 by the first fastening bolt 3122. The other end of the connecting plate 311 is provided with a third connecting hole 3112. The water tank 2 is provided with a fourth connecting hole 22 at the corresponding position of the third connecting hole 3112. The third connecting hole 3112 and the fourth connecting hole 22 are fixedly connected by the second fastening bolt 23. In order to ensure the sealing, the connection of the third connecting hole 3112, the fourth connecting hole 22, and the second fastening bolt 23 are all sealed to prevent water leakage.

[0035] The test tube 6 has a stainless steel support tube 61 inside, and multiple windows 62 are opened around the stainless steel support tube 61. Titanium wire mesh is wrapped around the outer periphery of the stainless steel support tube 61.

[0036] Simply placing titanium wire mesh inside the test tube results in uneven distribution of the mesh due to buoyancy. Therefore, a stainless steel support tube is installed with windows to maximize the amount of pharmaceutical wastewater that can enter the test tube. By wrapping the titanium wire mesh around the surface of the stainless steel support tube and further securing it with fixing devices such as cable ties, the pharmaceutical wastewater in all parts of the test tube can be uniformly exposed to ultraviolet light and photocatalytic oxidation during photocatalytic oxidation, thus improving the stability of the experiment.

[0037] To prevent the stainless steel support tube 61 from sticking to the test tube 6, which would make it difficult to install the titanium wire mesh, the outer diameter of the stainless steel support tube 61 is smaller than the inner diameter of the test tube 6, and four spaced guide support strips 611 are provided at both the upper and lower ends in the circumferential direction.

[0038] The ultraviolet generator 7 is a waterproof ultraviolet lamp. One end of the waterproof ultraviolet lamp 7 located in the water storage chamber 21 is a terminal 71. The terminal 71 is connected to the voltage regulator 9 through a wire (not shown in the figure). The number of voltage regulators 9 is the same as the number of waterproof ultraviolet lamps.

[0039] A voltage stabilizer connection plate 25 is installed outside the water tank 2. The voltage stabilizer 9 is installed on the voltage stabilizer connection plate 25 and then installed on the side of the water tank 2 through the voltage stabilizer connection plate 25.

[0040] The ultraviolet lamp tube can generate ozone. The ozone can undergo a photocatalytic oxidation reaction with the titanium wire mesh and the catalytic module supported on the titanium wire mesh. At the same time, the catalytic module can also adsorb pharmaceutical wastewater. The specific catalytic module can be set as a titanium dioxide catalyst.

[0041] In the second embodiment, there are five test tubes 6. The water tank 2 is provided with a partition baffle 24 that divides the interior of the water tank 2 into five water storage chambers 21. Each test tube 6 is located in an independent water storage chamber 21. The outside of the water tank 2 is provided with a water inlet connector 4 that is individually connected to each water storage chamber 21.

[0042] The water tank 2 is divided into five independent water storage chambers 21 by the partition baffle 24. A test tube 6 is installed in each water storage chamber 21. Then, by setting up water inlet connectors 4 on the water tank 2 to communicate with each water storage chamber 21, a water tank 2 that can test 5 groups of pharmaceutical wastewater at the same time is obtained. Different components of pharmaceutical wastewater can be tested in each test tube 6. Each water inlet connector 4 is connected to different components of pharmaceutical wastewater, further improving versatility.

[0043] The advantages of this utility model are: strong versatility, multiple sets of tests can be carried out at the same time, small footprint and simple structure.
