[0002] Macrocyclic lactones are mainly molecules with more than twelve carbon atoms and at least one ester bond in the macrocyclic skeleton. Cyclodecadelactone, also known as safflower oleoresin, is a very important macrocyclic musk. It not only has the aroma of musk but also the fragrance of ambergris. It is widely used in the formulation of perfumes, cosmetics and food flavorings.

[0003] Currently, cyclopentadecanol sold on the market is mainly obtained through chemical synthesis. The production of cyclopentadecanol fragrances is a typical example of fine chemical production. Its production wastewater contains pollutants such as toluene, cyclic ketones, ethers, and acetic acid. The current treatment methods mainly involve micro-electrolysis and the Fenton process to treat this type of wastewater. However, most of the current treatment equipment is relatively large, with high construction and operating costs. It is difficult to match the treatment capacity of small-scale cyclopentadecanol production, resulting in resource waste and failing to guarantee good treatment results. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that most equipment is designed for large-scale wastewater treatment and has high construction and operating costs, and to propose an electrolysis device for treating high-concentration fragrance wastewater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electrolysis device for treating high-concentration fragrance wastewater includes a box body with an inlet and an outlet on both sides of the box body. Two partitions are vertically arranged in the inner cavity of the box body, which divide the inner cavity of the box body into an electrolysis chamber, a reaction chamber and a sedimentation chamber, and are respectively equipped with an electrolysis mechanism, a reaction mechanism and a sedimentation mechanism.

[0007] The upper part of the partition is provided with a water outlet, and the electrolysis mechanism includes electrolysis packing and multiple aeration pipes arranged below it.

[0008] The reaction mechanism includes a first baffle parallel to the partition plate at the top of the reaction chamber, a first dosing pipe disposed on the side of the first baffle near the electrolysis chamber, and multiple baffles disposed between the first baffle and the partition plate on one side of the electrolysis chamber.

[0009] The sedimentation mechanism includes a second baffle parallel to the partition plate arranged on the upper part of the sedimentation chamber near the outlet, an inclined plate assembly arranged on the side of the second baffle near the reaction chamber, and a second dosing pipe arranged above the inclined plate assembly.

[0010] Preferably, the electrolytic filler is an iron-carbon micro-electrolytic filler.

[0011] Preferably, a stirring assembly is provided in the reaction chamber on the side of the first baffle near the sedimentation chamber.

[0012] More preferably, the stirring assembly includes a vertically rotating main shaft, a plurality of stirring fans fixedly mounted on the main shaft, and a motor extending from the upper end of the main shaft and connected to the housing.

[0013] Preferably, the inclined plate assembly includes a plurality of inclined plates stacked and staggered.

[0014] Preferably, an overflow trough is connected to the outside of the water outlet, and a drain outlet is provided at one end of the overflow trough.

[0015] Preferably, the inlet end of the water inlet is connected to a filter box, the other end of the filter box is provided with an inlet pipe, and the filter box is provided with multiple filter screens.

[0016] Preferably, both the reaction chamber and the sedimentation chamber are equipped with a sewage discharge mechanism at the bottom.

[0017] More preferably, the sewage discharge mechanism includes a collection hopper, a sewage discharge port extending through the lower end of the collection hopper into the box body, and a sewage discharge valve disposed in the sewage discharge port.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this utility model, the high-concentration fragrance wastewater is treated in stages, and the macromolecular organic matter in the wastewater is fully degraded by electrolytic catalytic oxidation and Fenton method. The wastewater and the reagent are fully mixed by the turbulence of the water body, which ensures the full treatment effect of the wastewater.

[0020] 2. In this utility model, the wastewater and the reagent are further mixed by the design of the stirring component to ensure the full degradation of the wastewater. The wastewater is also flocculated with flocculants and other reagents to flocculate iron ions and other substances in the wastewater. The inclined plate component ensures the sedimentation effect, so as to ensure the full purification of the delivered water.

[0021] 3. In this utility model, different chambers are formed by dividing the box body, and the reaction is carried out in stages with the flow of water. This ensures a full reaction while avoiding the reverse flow of water. The functions of each chamber will not interfere with each other. The degradation treatment of high-agricultural fragrance wastewater is realized in a relatively small device. At the same time, it is easy to maintain each chamber separately and has good performance.

[0022] This utility model features a novel design and simple structure. By treating wastewater in stages, it avoids mutual interference between the functions of each chamber. While miniaturizing the equipment, it also ensures the full degradation of organic matter in the wastewater and the thorough purification of high-concentration fragrance wastewater.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4 An electrolysis device for treating high-concentration fragrance wastewater includes a housing 1 with an inlet 11 and an outlet 12 on both sides. Two vertical partitions 3 are installed inside the housing 1, dividing it into an electrolysis chamber 31, a reaction chamber 32, and a sedimentation chamber 33, each equipped with an electrolysis mechanism 4, a reaction mechanism 5, and a sedimentation mechanism 6. The partitions 3 separate the housing 1, allowing for graded treatment of the high-concentration fragrance wastewater to ensure effective treatment.

[0030] Each partition 3 has a water inlet 30 on its upper part. The electrolysis mechanism 4 includes an electrolysis packing 41 and multiple aeration pipes 42 below it. The electrolysis packing 41 is made of iron-carbon micro-electrolysis packing. The wastewater is electrolyzed using this packing, causing recalcitrant organic matter to break down and open its rings, thus achieving the purpose of degrading organic pollutants. Simultaneously, carbon is used as a catalyst and air as an oxidant to further oxidize and remove pollutants from the water. The aeration pipes 42 increase the contact area between the wastewater and the electrolysis packing 41, ensuring good wastewater treatment results. The aeration pipes 42 also help prevent internal caking of the electrolysis packing 41, extending its service life.

[0031] The reaction mechanism 5 includes a first baffle 51 parallel to the partition 3 on the upper part of the reaction chamber 32, a first dosing pipe 52 on the side of the first baffle 51 near the electrolysis chamber 31, and multiple baffles 53 between the first baffle 51 and the partition 3 on one side of the electrolysis chamber 31. The first baffle 51 prevents water from flowing directly into the sedimentation chamber 33, ensuring that the water flows uniformly through the first dosing pipe 52 to mix with the reagent. The inlet end of the first dosing pipe 52 is connected to a dosing device, through which Fenton reagent is introduced into the reaction chamber 32 to oxidize large molecular recalcitrant substances, ensuring the purification effect of high-concentration fragrance wastewater. The design of the baffles 53 changes the flow direction of the water multiple times after it flows through the reagent, allowing the water and reagent to mix thoroughly, thus ensuring the complete oxidation and decomposition of organic matter in the water.

[0032] The sedimentation mechanism 6 includes a second baffle 61 parallel to the partition 3, arranged on the upper part of the sedimentation chamber 33 near the outlet 12; an inclined plate assembly 63 on the side of the second baffle 61 near the reaction chamber 32; and a second dosing pipe 62 above the inclined plate assembly 63. The second baffle 61 prevents water from flowing directly to the outlet 12, ensuring effective sedimentation and purification of the water. Flocculants and other agents are introduced into the sedimentation chamber 33 through the second dosing pipe 62 to adjust the pH and flocculate and precipitate pollutants such as iron ions in the wastewater. The inclined plate assembly 63 shortens the settling distance and increases the sedimentation area, ensuring effective sedimentation of remaining pollutants in the wastewater.

[0033] Based on the above technical solution, when treating high-concentration fragrance wastewater, the wastewater is sent into the electrolysis chamber 31 through the inlet 11. Micro-electrolysis is performed through the electrolysis packing 41 to catalytically oxidize and degrade the recalcitrant organic matter in the wastewater. After preliminary treatment, the wastewater continues to flow into the reaction chamber 32, where Fenton reagent is added through the first dosing pipe 52 to further degrade the large-molecule recalcitrant substances. The design of the baffle 53 ensures that the reagent and wastewater are fully mixed. The wastewater continues to flow into the sedimentation chamber 33, where flocculants are used to flocculate iron ions and other substances in the wastewater. Sedimentation is carried out in conjunction with the inclined plate assembly 63. The purified water is then sent out through the outlet 12, thus achieving the purification treatment of high-concentration fragrance wastewater.

[0034] In this technical solution, such as Figure 1-4 As shown, a stirring assembly 54 is installed in the reaction chamber 32 on the side corresponding to the first baffle 51 near the sedimentation chamber 33. The stirring assembly 54 includes a vertically rotating main shaft 542, multiple stirring fans 541 fixedly mounted on the main shaft 542, and a motor 543 connected to the upper end of the main shaft 542 extending out of the housing 1. The motor 543 drives the stirring fans 541 to stir the water, further mixing the water and the reagent, ensuring the full treatment of large molecular recalcitrant substances in the wastewater, and ensuring the degradation effect of the wastewater.

[0035] In this technical solution, such as Figure 1-4 As shown, the inclined plate assembly 63 includes multiple stacked and staggered inclined plates. The inclined plates shorten the settling distance, increase the sedimentation area, ensure sufficient sedimentation of residual substances, and guarantee the purification effect of the delivered water.

[0036] In this technical solution, such as Figure 1-4 As shown, an overflow trough 64 is connected to the outside of the outlet 12, and a drain outlet 641 is provided at one end of the overflow trough 64. The water delivered from the outlet 12 is collected through the overflow trough 64 and discharged through the drain outlet 641, which facilitates the collection and subsequent treatment of the water.

[0037] In this technical solution, such as Figure 1-4 As shown, the inlet end of the water inlet 11 is connected to a filter box 2, and the other end of the filter box 2 is provided with an inlet pipe 21. The filter box 2 is provided with multiple filter screens 22. The wastewater is pre-filtered through the filter box 2 to avoid other solid pollutants in the wastewater from affecting the electrolysis effect, and also to prevent solid pollutants from depositing in the electrolysis packing 41, thus extending the service life of the electrolysis packing 41.

[0038] In this technical solution, such as Figure 1-4As shown, both the reaction chamber 32 and the sedimentation chamber 33 are equipped with a sludge discharge mechanism 7 at their bottom. The sludge discharge mechanism 7 includes a collection hopper 71, a sludge discharge port 72 extending through the lower end of the collection hopper 71 into the casing 1, and a sludge discharge valve 73 installed in the sludge discharge port 72. The sediment is collected through the collection hopper 71 and discharged through the sludge discharge port 72, facilitating subsequent sludge treatment.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
