Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a novel graphene oxide electrode electrochemical sewage treatment device. Background Art

[0002] Large-scale exploitation of oil and natural gas will lead to the generation of a large amount of oil and gas wastewater. The composition of the wastewater is complex. Due to the large number of petrochemical products, the reaction process and unit operations are complex, resulting in complex and changeable properties of the wastewater. The wastewater contains high levels of organic matter, especially hydrocarbons and their derivatives, and contains a variety of heavy metals, which will cause extremely serious pollution and harm to the environment. Achieving zero discharge of oil and gas wastewater has become a development consensus among enterprises.

[0003] The main harmful substances in oil and gas wastewater are organic matter. The existing electrochemical wastewater treatment method decomposes organic matter into carbon dioxide and water into harmless substances through electrochemical anodic oxidation. The electrocatalytic oxidation system can treat oil and gas field wastewater efficiently and economically. However, in the actual process of wastewater treatment, there are still problems such as low electrode performance and low degradation efficiency.

[0020] In this embodiment, the oil absorption component 400 is a structure for absorbing organic matter and a small amount of metal ions.

[0021] like Figure 1 and Figure 2As shown, the oil suction assembly 400 includes a water inlet pipe 401 fixedly connected to the left side of the main box body 1, the inner bottom wall of the main box body 1 is fixedly connected with a uniformly distributed support pipe 402, the support pipe 402 is a polytetrafluoroethylene tube, the top of the support pipe 402 is fixedly connected with a first oil suction port 403, and the left side of the support pipe 402 is fixedly installed with uniformly distributed impurity removal blades 404, which are composed of hydrophilic modified graphene, graphene sponge and polytetrafluoroethylene sheets, and can remove small particles. The support tube 402 is fixedly connected to the right side with a uniformly distributed connecting tube 405, and the right end of the connecting tube 405 is fixedly connected with a second oil suction port 406. The first oil suction port 403 and the second oil suction port 406 are both composed of oleophilic modified graphene sponge and polytetrafluoroethylene sheet. The bottom end of the first oil suction port 403 and the left end of the second oil suction port 406 are fixedly installed with filter paper 407, and the filter paper 407 is a kind of fast organic filter paper or mixed filter paper.

[0022] It should be noted that the right side of the main box body 1 and the right side of the electrolytic cell 3 are fixedly connected with a drain pipe 8, and the outer side of the drain pipe 8 is fixedly connected with an electric valve, which can control the switch of the drain pipe 8. The bottom end of the support pipe 402 passes through the bottom of the main box body 1 and is connected to the interior of the transition tank 201, so that the wastewater containing organic matter can be transported to the interior of the transition tank 201 through the support pipe 402.

[0023] In addition, the number of support tubes 402 can be appropriately increased or decreased according to the actual size of the main box body 1, and the number of impurity removal blades 404 and second oil suction ports 406 can be appropriately increased or decreased according to the depth of the main box body 1, wherein the first oil suction port 403 and the second oil suction port 406 are both trumpet-shaped and can allow liquid to pass through, allowing waste water to pass through the first oil suction port 403 and the second oil suction port 406 and be filtered by the filter paper 407 before entering the interior of the support tube 402.

[0024] In this embodiment, the sampling mechanism 500 is a structure for testing wastewater.

[0025] like Figure 1 As shown, the sampling inspection mechanism 500 includes a sampling inspection device 501 fixedly installed on the inner side of the main box body 1 , and a quick inspection device 502 is fixedly installed on the inner side of the transition groove 201 .

[0026] It should be noted that the sampling device 501 is composed of a sampling pipe and a small water pump fixedly connected to the outside of the sampling pipe. The sampling pipe is made of polytetrafluoroethylene. The outside of the sampling pipe is provided with evenly distributed through holes, so that wastewater of different depths can be sampled. The rapid testing device 502 includes two support plates fixedly connected between the front and rear inner walls of the transition tank 201. The top supports of the two support plates are fixedly connected with a support box. A sewage detection device is fixedly installed inside the support box. The bottom of the sewage detection equipment is fixedly connected with a through pipe that passes through the bottom of the support box. The bottom end of the sampling pipe passes through the main box body 1 and the support box and is fixedly connected to the top of the sewage detection equipment, so that the wastewater sampled by the sampling device 501 can be transported to the inside of the rapid testing device 502 for testing, and the wastewater that has been tested can be transported out normally.

[0027] In this embodiment, the electrical treatment mechanism 600 is a structure for electrically treating wastewater.

[0028] like Figure 1 As shown, the electrical treatment mechanism 600 includes a transition pipe 601 fixedly connected to the bottom of the transition block 2, a metering and detection device 602 is fixedly installed on the outer side of the transition pipe 601, an anode 603 is fixedly installed on the inner bottom wall of the electrolytic cell 3, the anode 603 is made of boron-modified graphene mineral wool, a cathode 604 is fixedly installed on the inner bottom wall of the electrolytic cell 3, and an oxygen production device 605 is fixedly installed on the right side of the transition block 2.

[0029] It should be noted that the top of the transition pipe 601 passes through the bottom of the transition block 2 and is connected to the interior of the transition tank 201. The inner side of the transition tank 201 is inclined toward the side close to the transition pipe 601, so that the wastewater inside the transition tank 201 can enter the interior of the transition pipe 601 normally.

[0030] In addition, the bottom end of the transition pipe 601 passes through the top of the electrolytic cell 3, so that the wastewater can be transported to the inside of the electrolytic cell 3. The bottom of the oxygen production device 605 is fixedly connected to an oxygen supply pipe, and the left end of the oxygen supply pipe passes through the right side of the electrolytic cell 3, so that the oxygen produced by the oxygen production device 605 can be transported to the space inside the electrolytic cell 3 where the cathode 604 is located.

[0031] At the same time, a support frame 701 is fixedly connected between the bottom of the main box body 1 and the left side of the electrolytic cell 3, a vacuum pump 702 is fixedly installed on the inner bottom wall of the support frame 701, an exhaust pipe 703 is fixedly connected to the top of the vacuum pump 702, and an exhaust pipe 704 is fixedly connected to the top of the vacuum pump 702. The support frame 701 is a box body connected to the outside world on both sides, and the right end of the exhaust pipe 704 passes through the left side of the electrolytic cell 3. The gas inside the electrolytic cell 3 can be extracted by the vacuum pump 702, so that the closing frequency of the first oil suction port 403 and the second oil suction port 406 is controlled by the transition pipe 601, the transition groove 201 and the support pipe 402, thereby playing the function of controlling the wastewater transportation.

[0032] like Figure 3 , Figure 4 As shown, the fiber modification process: under the action of the first fixed wheel 10, the fiber rolled out of the raw material 9 can be tensioned, and the fiber passes through the second fixed wheel 12, the first fiber splitting wheel 11 and the second fiber splitting wheel 13, and then is split by the fiber splitting device 17, the fiber head is fixed on the multi-wheel clamp 16, the winding traction wheel 14 is combined with the third fixed wheel 15 to embed the fiber into the winding traction wheel 14, the multi-wheel clamp 16 is released, and the winding traction wheel 14 is used to sequentially pass the fiber through the tension reduction and static electricity removal preheating zone, the slurry coating zone 1, the slurry coating zone 2, the surface flash drying zone, the low-temperature hydrothermal reaction, the slurry removal zone, the high-temperature hydrothermal reaction, the tension reduction and static electricity removal preheating zone, and then is wound 24; Pretreatment after fiber separation: The fibers after fiber separation 17 are coated with graphene oxide slurry (slurry coating 18), and then a layer of PVA film is coated on the surface (slurry coating 2 19). Multiple fibers can be separated and treated to achieve a better reaction effect. Hydrothermal treatment (hydrothermal treatment 20) is performed to graft graphene oxide on the fiber surface, and the PVA film and unreacted graphene oxide are removed (de-slurrying 21). Further hydrothermal reaction (hydrothermal treatment 22) is performed to obtain the desired product of boron-modified graphene oxide. The product is treated to remove static electricity to prevent subsequent adsorption and entanglement (static electricity removal 23), and finally rolled up 24 for storage.

[0033] It should be noted that in the fiber modification process, the first fiber separation wheel 11 and the second fiber separation wheel 13 are ultrasonic vibration wheels with fine corrugated surfaces. The surface of the winding and traction wheel 14 is a thermoplastic elastomer. The middle of the winding and traction wheel 14 is made of stainless steel and is equipped with a heating device inside. Before use, the temperature needs to be raised to the temperature range of the thermoplastic elastomer from the high elastic state to the viscous flow state, so that the fiber can be embedded in the wheel surface and then cooled to fix the fiber head.

[0034] In addition, the alcoholysis degree of PVA is ≥99%, the tension reduction and static electricity removal preheating zone is an ethanol aqueous solution spray drying, and is equipped with a condensation circulation device for recycling. The slurry coating zone one and the slurry coating zone two are low temperature zones with a temperature of 0~20℃. The slurry coating zone one is a graphene oxide slurry paste, and the slurry coating zone two is a PVA resin. Both the slurry coating zone one and the slurry coating zone two are provided with holes of fixed size, and the coating thickness is set according to the slurry concentration and the fiber size. The surface flash drying zone is a microwave heating surface that flashes quickly to form a PVA film. The low-temperature hydrothermal reaction temperature is <95℃, the deslurry zone temperature is >95℃, the high-temperature hydrothermal reaction temperature is >95℃, and the high-temperature hydrothermal reaction contains a borate aqueous solution.

[0035] The working principle of the above embodiment is: When treating wastewater, the wastewater is introduced into the interior of the main box 1 through the water inlet pipe 401, and the organic matter in the wastewater is adsorbed under the action of the first oil suction port 403 and the second oil suction port 406. At the same time, the impurity removal blades 404 can adsorb small particles and a small number of metal ions in the wastewater, and the vacuum pump 702 is started. The air in the electrolytic cell 3 is extracted through the exhaust pipe 704 and discharged to the outside through the exhaust pipe 703. At the same time, the air pressure inside the electrolytic cell 3 drops, which will cause the first oil suction port 403 and the second oil suction port 406 to shrink and squeeze, and the organic matter enters the interior of the support tube 402 through the filter paper 407. It is then transported to the interior of the transition tank 201, and finally transported to the interior of the electrolytic cell 3 through the transition pipe 601 after real-time detection by the metering and detection device 602. The oxygen production device 605 is started, and oxygen is introduced around the cathode 604, and electrochemical treatment can be started in conjunction with the anode 603. The carbon dioxide generated by the treatment can be extracted by the vacuum pump 702 and discharged to the outside through the exhaust pipe 703, and the treated wastewater can be discharged through the bottom drain pipe 8. The sampling device 501 is started, and the wastewater inside the main box 1 is transported to the quick detection device 502. If it meets the qualified standards, it can be discharged through the top drain pipe 8.

[0036] Compared with the prior art, the novel graphene oxide electrode electrochemical sewage treatment device can effectively increase the performance and efficiency of electrochemical treatment through the coordinated use of the oil absorption component 400 inside the main box 1 and the electrical treatment mechanism 600 at the bottom. Different functional areas are set according to the different functions of graphene, which can fully utilize the characteristics of graphene and reduce some unnecessary devices and facilities, thereby reducing the treatment cost. As a new material, graphene has the advanced properties of nanomaterials, and its conductivity, adsorption and mechanical properties are stronger than most materials. Its addition as a functional material can fully improve the various properties of the modified material. The surface of graphene oxide has many functional functional groups. As a carrier of modified graphene, the graphene can have different properties, such as hydrophilicity, lipophilicity, etc., by modifying and replacing the functional groups. Boron-doped graphene can change the original electronic configuration and improve the stability of its electrochemical efficiency. At the same time, boron-doped graphene can be used as a non-metallic oxidation catalyst to greatly improve the oxidation and decomposition efficiency of organic matter and reduce the oxidation time.

[0037] The novel graphene oxide electrode electrochemical wastewater treatment device can produce novel fiber modified materials by designing related fiber modification processes with graphene as the core. The application of novel fiber modified materials can increase the efficiency of electrochemical treatment, while greatly improving the uniformity of the physical and chemical properties of the fibers. It also saves production and use costs to a certain extent, and solves the problems of low electrode performance and low degradation efficiency in the existing electrochemical wastewater treatment process.
