Description

Technical Field

[0001] This invention belongs to the field of tylosin wastewater treatment technology, and particularly relates to a tylosin wastewater pollution treatment device. Background Technology

[0002] With the development of the pharmaceutical industry, the discharge of antibiotic wastewater has posed a serious threat to the environment. Tylenol, a broad-spectrum antibiotic, generates wastewater containing high concentrations of recalcitrant organic compounds during its production. These substances not only possess high chemical stability but are also difficult to remove effectively using traditional wastewater treatment methods, leading to their persistent presence and accumulation in natural water bodies, posing a potential risk to the ecological environment and human health. Therefore, developing an efficient and reliable treatment technology to address the tylenol wastewater pollution problem is particularly urgent.

[0003] Currently, methods for treating antibiotic wastewater mainly include biological methods, physicochemical methods, and advanced oxidation technologies. However, biological methods often exhibit low degradation efficiency for certain types of antibiotics, such as tylosin, due to their complex molecular structure and strong antibacterial activity. While physicochemical methods can remove pollutants to some extent, they typically require large amounts of chemical reagents and may generate secondary pollution. In contrast, advanced oxidation technologies, with their powerful oxidizing capabilities, can destroy the molecular structure of antibiotics in a short time, achieving deep purification. However, in practical applications, they still face challenges such as high cost and complex operation.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a tylosin wastewater pollution treatment equipment that can achieve efficient degradation of harmful substances in wastewater through multi-stage filtration, electrochemical oxidation and enhanced oxidation processes, and ensure that the treated wastewater meets the discharge standards, so as to overcome the shortcomings in current practical applications.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] like Figure 1-6As shown, an embodiment of the present invention provides a tylosin wastewater pollution treatment device, including a base platform 11 and a base support rod 10 fixed thereon. An electrochemical tank 13 and a reaction chamber 8 are respectively fixed to the upper end of the base support rod 10. The bottom of the electrochemical tank 13 is connected to the top of the reaction chamber 8 via a water supply assembly. A drain pipe 23 is provided at the bottom of the reaction chamber 8. A raw water treatment tank 2 is supported and fixed to the top of the electrochemical tank 13 by a lateral reinforcement beam 12. A wastewater inlet is provided at the top of the raw water treatment tank 2. The bottom of the raw water treatment tank 2 is connected to the top of the electrochemical tank 13 via a first water supply channel 4. The device also includes:

[0034] A two-stage filtration assembly is installed on the upper inner side of the raw water treatment tank 2 for filtering impurities from the wastewater.

[0035] The coagulation and sedimentation adjustment component is installed on the lower inner side of the raw water treatment tank 2. The coagulation and sedimentation adjustment component is used to adjust the pH of the wastewater and to perform flocculation and sedimentation.

[0036] An electrochemical oxidation reaction assembly is installed inside the electrochemical box 13. The electrochemical oxidation reaction assembly is used to generate hydroxyl radicals through electrolysis to decompose the molecular structure of tylosin.

[0037] An enhanced oxidation component is installed inside the reaction chamber 8. The enhanced oxidation component is used to degrade recalcitrant organic matter in wastewater.

[0038] The electrochemical oxidation reaction assembly includes partitioned isolation plates 33 arranged circumferentially on the inner side of the electrochemical box 13. The lower end of the partitioned isolation plates 33 is spaced a certain distance from the inner bottom of the electrochemical box 13. A rectifier and guide plate 34 is installed on the upper inner side of the electrochemical box 13. The area between two adjacent partitioned isolation plates 33 is the electrolysis zone. An anode 35 and a cathode 36 are supported and fixed in the electrolysis zone by a positioning rod 37.

[0039] In this embodiment of the invention, wastewater is added to the inner side of the raw water treatment tank 2 and first undergoes secondary filtration through a two-stage filtration assembly. Then, the wastewater passes through a coagulation and sedimentation assembly for pH adjustment and flocculation sedimentation. The wastewater is then introduced into the inner side of the electrochemical tank 13 via the first water conveying channel 4. The electrochemical oxidation reaction assembly generates hydroxyl radicals through electrolysis, decomposing the molecular structure of tylosin. The rectifier guide plate 34 ensures uniform distribution of the wastewater within the electrolysis zone. Within the electrolysis zone, the anode 35 and cathode 36 are supported and fixed by positioning rods 37, allowing for reliable and complete electrochemical oxidation reactions. The wastewater is then transported to the inner side of the reaction chamber 8 via a water conveying assembly. The enhanced oxidation assembly further degrades recalcitrant organic matter in the wastewater, ensuring that the wastewater treatment meets standards.

[0040] In summary, this invention achieves efficient degradation of harmful substances in wastewater through multi-stage filtration, electrochemical oxidation, and enhanced oxidation processes, ensuring that the treated wastewater meets discharge standards.

One end of the mounting positioning rod 37 is fixedly connected to the convergence point of the partition isolation plate 33, and the other end of the mounting positioning rod 37 is fixedly connected to the inner wall of the electrochemical box 13.

[0043] Preferably, the anode 35 is a titanium-based ruthenium-iridium coated electrode, and the cathode 36 is a titanium plate or stainless steel plate electrode. It can be powered by a DC power supply (constant voltage / constant current mode, with adjustable voltage), and there are no limitations. During operation, when a DC voltage of 15-20V is applied, the anode 35 generates ClO⁻ and ·OH, directly disrupting the lactone ring structure of tylosin and achieving molecular chain breakage.

[0044] The degradation mechanism is as follows:

[0048] The rectifier guide plate 34 is horizontally arranged so that the wastewater can flow evenly, so that the wastewater is evenly distributed to the electrolysis zone. The lower end of the first water conveying channel 4 is connected to the upper space of the rectifier guide plate 34.

[0049] The distance between the lower end of the partition plate 33 and the bottom of the electrochemical box 13 is greater than 1cm, which not only ensures that each electrolysis zone is interconnected and the final water level is consistent, but also allows the water to be discharged through the water conveying assembly.

One end of the second water conveying channel 5 is connected to the bottom of the inner cavity of the electrochemical tank 13. The pump 22 is also installed on the second water conveying channel 5.

The flow guide plate 25 is inclined downwards at the end near the wastewater inlet, and a drain outlet is formed between the end of the flow guide plate 25 near the wastewater inlet and the inner wall of the raw water treatment tank 2. To improve the stability of the flow guide plate 25, the end of the flow guide plate 25 near the wastewater inlet is also fixedly connected to the inner wall of the raw water treatment tank 2 by a diagonal tie rod 27. To facilitate cleaning of the coarse filter plate 24 and the fine filter plate 26, a corresponding sludge discharge port 20 is provided on the side wall of the raw water treatment tank 2.

[0052] Preferably, the coarse filter plate 24 and the fine filter plate 26 can be made of coarse screen (10-20mm) and fine screen (1-5mm) to achieve two-stage filtration of wastewater.

Multiple mixing rods 30 are evenly distributed around the outside of the drive shaft 19. The mixing rods 30 are fixedly connected to the drive shaft 19 through three mixing pipes 28. A differential mesh plate 29 is fixed between two adjacent mixing pipes 28 corresponding to one mixing rod 30. The differential mesh plates 29 corresponding to the mixing rods 30 are evenly staggered left and right to improve the differential stirring effect of the disturbance. The drive spindle 19 is sealed and rotatably connected to the main flow pipe 18 at the end away from the first motor 3. Multiple first liquid storage containers 1 are also fixed on the side wall of the raw water treatment tank 2. The bottom of the first liquid storage container 1 is connected to the main flow pipe 18 through the bypass pipe 17. An electric control valve 16 is also installed on the bypass pipe 17. The bypass pipe 17 is connected to the mixing pipe 28 through the main flow pipe 18 and the inner cavity of the drive spindle 19 in sequence. An outlet hole is also opened in the middle of the mixing pipe 28.

[0054] Preferably, the first storage container 1 includes a NaOH / H2SO4 storage container, with an online pH sensor installed as needed, and a metering pump (not shown, can be installed inside the first storage container 1, not limited) automatically adding pH for pH neutralization. The first storage container 1 also includes a polyaluminum chloride storage container and a polyacrylamide storage container, used for rapid mixing and slow flocculation, respectively. In practical applications, pH neutralization, rapid mixing, and slow flocculation can be performed sequentially depending on the water quality, or one or more of these steps can be selected, without limitation.

[0055] The regulating coagulation and sedimentation assembly also includes a cylindrical mud-water separation cylinder 14 fixed to the lower end of the raw water treatment tank 2. A long strip sedimentation tank (not shown) is provided between the raw water treatment tank 2 and the mud-water separation cylinder 14. A transmission shaft 32 is rotatably installed in the middle of the inner side of the mud-water separation cylinder 14. A third motor 15, which is connected to the transmission shaft 32, is fixed to one end of the mud-water separation cylinder 14. A screw propeller 31 is installed and fixed on the transmission shaft 32 inside the mud-water separation cylinder 14. A sediment discharge pipe 21 is also provided at one end of the mud-water separation cylinder 14. The third motor 15 is started periodically to drive the screw propeller 31 to rotate, so that the sediment can be transported and discharged through the sediment discharge pipe 21.

[0056] like Figure 1 , 2 As shown in Figure 6, in a preferred embodiment of the present invention, the reaction chamber 8 adopts a cylindrical structure. The enhanced oxidation component includes a power shaft 42 vertically rotatably mounted in the middle of the reaction chamber 8. A second motor 7, which is connected to the power shaft 42, is fixed at the top of the reaction chamber 8. Multiple sets of first porous homogenizing components 39 and second porous homogenizing components 40 are longitudinally and uniformly interspersed on the power shaft 42. Both the first porous homogenizing components 39 and the second porous homogenizing components 40 include multiple porous plates evenly distributed circumferentially. The porous plates of adjacent sets of first porous homogenizing components 39 and second porous homogenizing components 40 are evenly interspersed. Multiple elastic support members 41 are connected between the porous plates of adjacent sets of first porous homogenizing components 39 and between the porous plates of adjacent sets of second porous homogenizing components 40. The elastic support members 41 are preferably springs or the like. Through the combination of the first porous homogenizing components 39, the second porous homogenizing components 40 and the elastic support members 41, the processing efficiency of oxidation of recalcitrant organic matter is improved.

[0057] The top of the reaction chamber 8 is also provided with multiple second liquid storage containers 6 for adding treatment liquid into its inner cavity. The second liquid storage containers 6 include FeSO4 liquid storage containers and H2O2 liquid storage containers. The inner wall of the reaction chamber 8 is also provided with a heating layer 38 to form a temperature control system, so that the temperature is maintained within a suitable range (40-50℃).

[0058] In addition, the device is also equipped with an ORP sensor (to monitor redox potential and ensure a complete reaction) as needed.

[0059] The degradation mechanism is as follows: ;

[0060] ·OH free radicals further oxidize intermediate products (such as benzene ring substances) after electrochemical treatment.

[0061] When applied, adding FeSO4 (0.1-0.3 mol / L) and H2O2 (2-4 mol / L) further oxidizes intermediate products (such as benzene ring compounds), achieving a COD removal rate of over 85%. The electrochemical-enhanced oxidation coupling process enables a teratin degradation rate of ≥99%, with effluent COD ≤50 mg / L.

[0065]

[0066] The above embodiments of the present invention provide a tylosin wastewater pollution treatment device, the working principle of which is as follows:

[0067] Wastewater is first added to the inside of raw water treatment tank 2, where it undergoes preliminary impurity removal through a two-stage filtration system. The coarse filter plate 24 and the fine filter plate 26 perform primary and secondary filtration of the wastewater, respectively.

[0068] The filtered wastewater undergoes pH adjustment, coagulation and mixing, and flocculation sedimentation in a coagulation and sedimentation unit. This unit includes a drive shaft 19, a mixing rod 30, a mixing pipe 28, and other components, and works in conjunction with a first storage container 1 to store chemical agents such as NaOH / H2SO4, polyaluminum chloride, and polyacrylamide for water quality adjustment and flocculation sedimentation, separating sludge. Periodically starting a third motor 15 drives a screw propeller 31 to rotate, transporting the sediment and discharging it through the sediment discharge pipe 21.

[0069] The pre-treated wastewater is introduced into the inner side of the electrochemical tank 13 through the first water conveyance channel 4, and is evenly distributed to each electrolysis zone under the action of the rectifier guide plate 34. The anode 35 and cathode 36 are fixed by the mounting positioning rod 37. Electrolysis generates active substances such as hydroxyl radicals, which efficiently oxidize and decompose recalcitrant organic matter such as tylosin.

[0070] The wastewater is then transported to the inside of the reaction chamber 8 via the second water conveyance channel 5 and the pump 22, where it undergoes further deep treatment under the action of the enhanced oxidation component. This component includes a power shaft 42, a first porous homogenizing component 39, a second porous homogenizing component 40, and an elastic support 41, and reacts fully with reagents such as FeSO4 and H2O2 in the second liquid storage container 6. The heating layer 38 controls the reaction temperature between 40-50°C to improve oxidation efficiency.

[0071] Finally, the wastewater treated by the above steps is discharged through the drain pipe 23, which is equipped with an adsorption separation component 9 including an activated carbon adsorption module and a membrane separation module (nanofiltration membrane) to further remove residual organic matter and macromolecular substances, ensuring that the effluent meets the discharge standards.

[0072] In summary, this invention achieves efficient removal of recalcitrant organic matter from tylosin wastewater through multi-stage filtration, electrochemical oxidation, and enhanced oxidation processes, ensuring that the treated wastewater meets discharge standards.

All circuits, electronic components, and modules involved are existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this invention does not involve improvements to the software and methods.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
