Description

Technical Field

[0001] The invention belongs to the technical field of tulathromycin waste liquid water treatment, and in particular relates to tulathromycin waste liquid water pollution treatment equipment. Background Art

[0002] With the development of the pharmaceutical industry, the discharge of antibiotic wastewater poses a serious threat to the environment. The production of tulathromycin, a broad-spectrum antibiotic, generates wastewater containing high concentrations of recalcitrant organic matter. These substances are not only chemically stable but also difficult to effectively remove 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, the development of an efficient and reliable treatment technology to address the problem of tulathromycin wastewater pollution is particularly urgent.

[0003] Currently, methods for treating antibiotic wastewater mainly include biological methods, physical and chemical methods, and advanced oxidation technologies. However, biological methods often show low degradation efficiency for certain types of antibiotics, such as tulathromycin, due to their complex molecular structure and strong antimicrobial activity. Although physical and chemical methods can remove pollutants to a certain extent, they usually require the consumption of large amounts of chemical agents and may cause secondary pollution. In contrast, advanced oxidation technology, with its powerful oxidizing ability, can destroy the molecular structure of antibiotics in a relatively short period of time and achieve deep purification, but in actual application, it still faces problems such as high cost and complex operation.

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

The device also includes: Two-stage filter assembly: a two-stage filter assembly for filtering impurities from wastewater is installed on the upper inner side of the raw water treatment tank 2; Adjustment coagulation and sedimentation component: the adjustment coagulation and sedimentation component is installed at the lower inner part of the raw water treatment tank 2, and the adjustment coagulation and sedimentation component is used to adjust the pH of the wastewater and perform flocculation and sedimentation; An electrochemical oxidation reaction component is installed inside the electrochemical box 13, and the electrochemical oxidation reaction component is used to generate hydroxyl radicals by electrolysis to decompose the molecular structure of tulathromycin; Enhanced oxidation component: an enhanced oxidation component is installed inside the reaction chamber 8, and the enhanced oxidation component is used to degrade the difficult-to-decompose organic matter in the wastewater; Among them, the electrochemical oxidation reaction component includes partition isolation plates 33 distributed on the inner circumference of the electrochemical box 13, the lower end of the partition isolation plate 33 is set at a certain distance from the inner bottom of the electrochemical box 13, and a rectifying guide plate 34 is installed on the inner upper part of the electrochemical box 13; the area between two adjacent partition isolation plates 33 is the electrolysis zone, and the anode 35 and the cathode 36 are supported and fixed in the electrolysis zone by installing a positioning rod 37.

[0023] In this embodiment of the present invention, wastewater is added to the interior of the raw water treatment tank 2 and first undergoes secondary filtration through a two-stage filtration assembly. The wastewater then undergoes pH adjustment and flocculation precipitation through a coagulation and sedimentation assembly. The wastewater is then introduced into the interior of the electrochemical tank 13 through a first water supply channel 4. The electrochemical oxidation reaction assembly generates hydroxyl radicals through electrolysis, decomposing the molecular structure of tulathromycin. The rectifying guide plate 34 evenly distributes the wastewater throughout the electrolysis zone, where anode 35 and cathode 36 are supported and fixed by positioning rods 37, enabling reliable and sufficient electrochemical oxidation reactions.

[0037] like Figure 1 、 2 As shown in Figure 6, as a preferred embodiment of the present invention, the reaction chamber 8 adopts a cylindrical barrel structure, the enhanced oxidation component includes a power shaft 42 vertically rotatably installed in the middle of the reaction chamber 8, and a second motor 7 connected to the power shaft 42 is fixed on the top of the reaction chamber 8. A plurality of groups of first porous homogeneous components 39 and second porous homogeneous components 40 are uniformly and staggeredly fixed on the power shaft 42 in the longitudinal direction. The first porous homogeneous components 39 and the second porous homogeneous components 40 both include a plurality of porous plates uniformly distributed in the circumferential direction, and the porous plates of two adjacent groups of the first porous homogeneous components 39 and the second porous homogeneous components 40 are uniformly staggered. A plurality of elastic support members 41 are connected between the porous plates of two adjacent groups of the first porous homogeneous components 39 and between the porous plates of two adjacent groups of the second porous homogeneous components 40.

[0039] In addition, the device is also equipped with an ORP sensor as needed (to monitor the redox potential and ensure sufficient reaction).

[0040] The degradation mechanism is: ; OH radicals further oxidize the intermediate products (such as benzene ring substances) after electrochemical treatment.

[0041] During application, the addition of FeSO₄ (0.1-0.3 mol / L) and H₂O₂ (2-4 mol / L) further oxidizes intermediates (such as benzene rings), achieving a COD removal rate exceeding 85%. The electrochemical-enhanced oxidation coupling process achieves a tulathromycin degradation rate of ≥99%, with effluent COD ≤50 mg / L.

[0044] Table 1 Changes in tulathromycin concentration and COD in each treatment step The above embodiment of the present invention provides a tulathromycin waste liquid water pollution treatment device, the working principle of which is as follows: Wastewater is first fed into the raw water treatment tank 2 and passes through a two-stage filter assembly for preliminary impurity removal.

[0046] After preliminary treatment, wastewater is introduced into the interior of electrochemical tank 13 through first water channel 4 and evenly distributed to each electrolysis zone by rectifying and guiding plates 34. Anode 35 and cathode 36 are secured by mounting rods 37. Electrolysis generates active substances such as hydroxyl radicals, which efficiently oxidize and decompose recalcitrant organic matter like tulathromycin.

[0047] The wastewater is then transported to the interior of the reaction chamber 8 via the second water delivery channel 5 and the pump 22, where it undergoes further treatment in the enhanced oxidation assembly. This assembly comprises a power shaft 42, a first porous homogenizing assembly 39, a second porous homogenizing assembly 40, and an elastic support 41. It reacts with the FeSO₄ and H₂O₂ reagents in the second liquid storage container 6 to produce a full reaction. A heating layer 38 maintains the reaction temperature between 40°C and 50°C to enhance oxidation efficiency.

[0048] Finally, the wastewater treated in the above steps passes through the drain pipe 23, where the adsorption separation component 9 includes an activated carbon adsorption module and a membrane separation module (nanofiltration membrane) to further remove residual organic matter and macromolecular substances to ensure that the effluent meets the discharge standards.

[0049] In summary, the present invention achieves efficient removal of refractory organic matter in tulathromycin wastewater through multi-stage filtration, electrochemical oxidation and enhanced oxidation processes, ensuring that the treated wastewater meets discharge standards.
