[0002] The coal chemical desalination process is mainly used to treat coal chemical wastewater, achieving zero wastewater discharge and resource utilization of crystalline salts. In its treatment process, sulfur autotrophic microorganisms use sulfur compounds as electron donors to fix carbon dioxide and remove nutrients such as nitrogen and phosphorus from the wastewater. It has advantages such as no need to add additional organic carbon sources, low sludge production, and strong tolerance to toxic and harmful substances, making it more suitable for wastewater treatment in the coal chemical industry.

[0003] Existing sulfur autotrophic equipment, such as the sulfur autotrophic denitrification reactor disclosed in invention patent CN112573652A, includes a main reactor, inlet equipment, deoxygenation device, reflux device, and acid / alkali dosing device. Wastewater enters the sulfur autotrophic denitrification zone within the main reactor for purification. Before use, the prepared sulfur autotrophic carrier needs to be filled into the main reactor. However, existing main reactors lack a mechanism for layered carrier filling. This not only leads to areas with large local voids within the filled carrier, reducing the contact area between the water and the carrier, but also results in uneven microbial distribution within the main reactor, affecting wastewater treatment efficiency.

[0049] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0050] like Figure 1As shown, the present invention discloses a sulfur autotrophic device for a coal chemical salt separation process, comprising a reactor body 1, three baffles 2, a feeder 3, an aeration pipe 4, and a drain trough 5. The reactor body 1 has a barrel-shaped structure and is preferably made of high-strength, corrosion-resistant materials such as fiberglass or stainless steel. An inlet 101 and an outlet 102 are provided on the side wall of the reactor body 1, and both the inlet 101 and the outlet 102 are connected to the interior of the reactor body 1. The baffles 2 are fixedly installed inside the reactor body 1, and the three baffles 2 are spaced apart. A sliding hole 201 is provided in the middle of each of the three baffles 2, and the three sliding holes 201 are coaxially arranged. A water passage hole 202 is provided in the middle baffle 2, and the water passage hole 202 is located at the outer edge of the baffle 2. The inlet 101 is located below the three baffles 2, and the outlet 102 is located above the three baffles 2. When the sulfur autotrophic carrier is filled above each baffle 2 and the sliding hole 201 in the middle baffle 2 is blocked, the water entering the reactor body 1 through the inlet 101 first flows upward along the sliding hole 201 in the lower baffle 2, then passes through the water passage 202, and then flows upward along the sliding hole 201 in the upper baffle 2, and finally is discharged through the outlet 102. The baffles 2 guide the water, making the wastewater form a complex flow pattern in the reactor body 1, increasing the contact time and contact area between the wastewater and the microorganisms in the sulfur autotrophic carrier, thereby improving the wastewater treatment effect.

[0051] Inlet 101 is connected to the influent system, which is equipped with a water quality monitoring and regulation device. This device can monitor the wastewater's water quality parameters in real time and automatically adjust the wastewater flow rate, pH value, and nutrient concentration based on the monitoring results to meet the requirements of the sulfur autotrophic reaction. Simultaneously, the influent system also includes a pretreatment unit, comprising processes such as filtration, sedimentation, and adsorption, which can remove large particulate impurities, suspended solids, and some toxic and harmful substances from the wastewater, reducing the burden on subsequent treatment units.

[0052] The outlet 102 is connected to the drainage system, which combines level control and water quality monitoring. This system automatically controls the opening and closing of the drainage valve based on the liquid level inside the reactor body 1 and the quality of the effluent. When the liquid level inside the reactor body 1 reaches the set height, the drainage system automatically opens, discharging the treated wastewater from the reactor body 1. Simultaneously, the drainage system monitors the discharged wastewater in real time. If the effluent quality fails to meet discharge standards, the wastewater is automatically returned to the reactor body 1 for secondary treatment.

[0053] Aeration pipe 4 is fixedly installed on the bottom side inside the reactor body 1. It adopts a combination of microporous aeration and jet aeration, which can automatically adjust the aeration intensity and aeration time according to the dissolved oxygen concentration and metabolic needs of microorganisms within the reactor body 1. The microporous aeration device provides fine bubbles, increasing oxygen dissolution efficiency and providing sufficient dissolved oxygen for sulfur autotrophic bacteria. The jet aeration device promotes wastewater mixing and mass transfer, improving the uniformity of dissolved oxygen distribution within the reactor body 1.

[0054] The drain trough 5 is fixedly installed above the reactor body 1, such as... Figure 1 and Figure 12 As shown, multiple V-shaped grooves 501 are provided on the top side of the sidewall of the drain tank 5. The multiple V-shaped grooves 501 are arranged in a circumferential array around the center line of the reactor body 1, and the outlet 102 is connected to the interior of the drain tank 5. The V-shaped grooves 501 can block impurities floating on the liquid surface and prevent impurities from flowing into the outlet 102, thereby achieving a certain filtration effect.

[0055] To monitor the water treatment effect within reactor body 1 in real time, a detection system is installed within it. This system is equipped with various sensors that monitor different parameters within reactor body 1 in real time and transmit the data to the control system. The control system employs PLC control technology and intelligent algorithms, automatically adjusting the equipment's operating parameters based on the monitoring data to achieve automated operation and optimized control. Furthermore, the control system features remote monitoring and fault alarm functions. Operators can monitor the equipment's operating status in real time via mobile phones, computers, and other terminal devices, and receive timely alarm information when equipment malfunctions, facilitating maintenance and troubleshooting.

[0056] like Figures 2-4 As shown, the feeder 3 includes a mesh cylinder 31, a base plate 32, and a drive device 33. The mesh cylinder 31 is slidably disposed between three sliding holes 201, and feeding ports 301 are provided on the periphery of the mesh cylinder 31. Multiple feeding ports 301 are arranged in a circumferential array around the center line of the mesh cylinder 31. The base plate 32 is fixedly disposed inside the mesh cylinder 31 and is located below the feeding ports 301. The drive device 33 is used to drive the mesh cylinder 31 to move in a direction perpendicular to the partition plate 2, thereby causing the feeder 3 to move as shown in the diagram. Figures 2-4 Switch between the three states shown.

[0057] Sulfur autotrophic carriers are added to the mesh cylinder 31 in batches. The drive device 33 moves the mesh cylinder 31, ensuring that the carriers of the same batch are evenly filled onto each partition 2, thus making the amount of microorganisms on each partition 2 more uniform. After the sulfur autotrophic carriers are filled, the bottom plate 32 is moved into the sliding hole 201 located in the middle position and the bottom plate 32 seals the sliding hole 201, allowing the water to flow along a preset path.

[0058] Assuming the distance between the upper partition 2 and the lower partition 2 is the arrangement span, it is preferable that the distance from the bottom plate 32 to both ends of the mesh cylinder 31 is greater than the arrangement span. When the bottom plate 32 moves into the sliding hole 201 in the upper position, the lower end of the mesh cylinder 31 is located in the lower sliding hole 201, thereby preventing the carriers on the lower partition 2 and the middle partition 2 from falling into the bottom of the reactor body 1 through the sliding hole 201; when the bottom plate 32 moves into the sliding hole 201 in the middle position... When the bottom plate 32 moves into the upper sliding hole 201, the upper and lower ends of the mesh cylinder 31 are located in the upper sliding hole 201 and the lower sliding hole 201, respectively, thereby preventing the carriers on the upper partition 2 and the lower partition 2 from passing through the sliding hole 201. Similarly, when the bottom plate 32 moves into the upper sliding hole 201, the lower end of the mesh cylinder 31 is located in the lower sliding hole 201, thereby preventing the carriers on the upper partition 2 and the middle partition 2 from passing through the sliding hole 201.

[0059] like Figure 9 As shown, the partition 2 includes an annular disk 21 and a connecting pipe 22. The annular disk 21 is fixedly installed inside the reactor body 1, and the sliding hole 201 is located in the middle of the annular disk 21. Figure 10 As shown, multiple water passage holes 202 are provided on the outer edge of the annular disc 21 located in the middle position. The connecting pipe 22 is fixedly installed on the top side of the annular disc 21, and the mesh cylinder 31 is slidably installed inside the connecting pipe 22. The cooperation between the mesh cylinder 31 and the connecting pipe 22 improves the sliding stability of the mesh cylinder 31 and the partition plate 2. At the same time, the bottom plate 32 can be moved into the connecting pipe 22 to block its sliding holes 201, thereby reducing the difficulty of controlling the lifting position of the bottom plate 32.

[0060] The drive device 33 includes a lead screw 331, a screw sleeve 332, a sliding shaft 333, a slip ring 334, a stirring rod 335, and a flexible plate 336, such as Figure 5As shown, the lead screw 331 is rotatably installed inside the reactor body 1 and passes through the bottom plate 32. The screw sleeve 332 is connected to the lead screw 331 by a threaded engagement and is fixedly connected to the bottom plate 32. The sliding shaft 333 is fixedly installed inside the reactor body 1 and is slidably connected to the bottom plate 32. When the reducer drives the lead screw 331 to rotate, the threaded engagement between the lead screw 331 and the screw sleeve 332 and the sliding engagement between the sliding shaft 333 and the bottom plate 32 can drive the screw sleeve 332 and the bottom plate 32 to move up and down, thereby realizing the drive device 33 to drive the mesh cylinder 31.

[0061] like Figure 6 and Figure 7 As shown, a groove 303 is provided on the periphery of the lead screw 331. The length direction of the groove 303 is parallel to the axial direction of the lead screw 331. A slip ring 334 is sleeved on the lead screw 331 and is slidably connected to the groove 303. The slip ring 334 is rotatably mounted on the top side of the base plate 32. When the lead screw 331 rotates, it can drive the base plate 32 to move up and down, thereby driving the slip ring 334 to move up and down. At the same time, since the slip ring 334 is slidably connected to the groove 303, the slip ring 334 also rotates.

[0062] One end of the stirring rod 335 is fixedly mounted on the slip ring 334. When the bottom plate 32 and the mesh cylinder 31 move up and down, the stirring rod 335 can be driven to rotate synchronously. The stirring rod 335 stirs the carrier, causing the carrier on the bottom plate 32 to be thrown onto the partition plate 2, thereby filling the gap between two adjacent partition plates 2 to ensure the processing performance of the sulfur autogenous equipment.

[0063] The flexible plate 336 is made of flexible materials such as rubber. It is fixedly installed on the bottom side of the stirring rod 335 and spaced apart from the top side of the bottom plate 32, thereby avoiding grinding of the carrier and ensuring the particle size of the sulfur autotrophic carrier.

[0064] like Figure 6 As shown, the upper side of the base plate 32 is provided with multiple grooves 302. The grooves 302 are shallow. When there is a lot of sulfur autotrophic carrier in the mesh cylinder 31, the bottom of the sulfur autotrophic carrier will be stuck in the groove 302, so that the sulfur autotrophic carrier at the bottom will not be discharged through the feed port 301. Only the sulfur autotrophic carrier at the upper position in the feed port 301 can be discharged through the feed port 301, thus reducing the filling speed of the sulfur autotrophic carrier. When there is a little sulfur autotrophic carrier in the mesh cylinder 31, the bottom of the sulfur autotrophic carrier will not be stuck in the groove 302, so it is easy to be discharged through the feed port 301. That is, the filling speed of the sulfur autotrophic carrier is balanced, making the filling of the sulfur autotrophic carrier more uniform.

[0065] like Figure 11As shown, the partition 2 located in the middle includes a lower plate 23 and an upper plate 24. The lower plate 23 is fixedly installed inside the reactor body 1 and is fitted onto the mesh cylinder 31. A first through hole 203 is opened inside the lower plate 23. The upper plate 24 is abutted against the top side of the lower plate 23 and is fitted onto the mesh cylinder 31. A second through hole 204 is opened inside the upper plate 24. The first through hole 203 and the second through hole 204 are connected and combined to form a water passage hole 202. By rotating the upper plate 24, the overlapping area of ​​the first through hole 203 and the second through hole 204 can be adjusted, thereby adjusting the cross-sectional area of ​​the water passage hole 202, so that the water passage hole 202 can be adapted to different specifications of sulfur autotrophic carriers, thereby improving the adaptability of this sulfur autotrophic equipment.

[0066] The first through hole 203 is a stepped hole, and the inner diameter of the upper end of the first through hole 203 is larger than the inner diameter of the lower end. The second through hole 204 is a stepped hole, and the inner diameter of the upper end of the second through hole 204 is smaller than the inner diameter of the lower end. The inner diameter of the lower end of the second through hole 204 is equal to the inner diameter of the upper end of the first through hole 203, and the inner diameter of the upper end of the second through hole 204 is equal to the inner diameter of the lower end of the first through hole 203. The combination of the first through hole 203 and the second through hole 204 forms a through hole that is thick in the middle and thin at both ends, which can play a certain role in preventing clogging and ensuring the smooth flow of water.

[0067] Multiple first through holes 203 and multiple second through holes 204 are provided, and the multiple first through holes 203 and multiple second through holes 204 are arranged in a circumferential array around the center line of the mesh cylinder 31.

[0068] When the number of first through holes 203 is the same as the number of second through holes 204, and the distance between the axes of two adjacent first through holes 203 is less than twice the inner diameter of the upper end of the first through hole 203, rotating the upper plate 24 at any angle will make the first through holes 203 and the second through holes 204 coincide, and the inner diameter of the water passage 202 formed by their combination will be the same.

[0069] The inner diameters of the first through hole 203 and the second through hole 204 are relatively small. In order to facilitate the opening of the partition plate 2, the distance between two adjacent first through holes 203 can be increased so that the distance between the axes of two adjacent first through holes 203 is equal to twice the inner diameter of the upper end of the first through hole 203. At this time, the number of first through holes 203 and the number of second through holes 204 are coprime numbers. The upper plate 24 can be rotated at any angle so that the first through holes 203 and the second through holes 204 coincide, so as to ensure the passage of water.

[0070] The method of using a sulfur autotrophic device for a coal chemical salt separation process according to the present invention is as follows:

[0071] S1, using the feeder 3, the prepared sulfur autotrophic carrier is evenly filled into the reactor body 1 to fill 70%-80% of the reactor body 1 volume.

[0072] S2. Inoculate the reactor body 1 with sulfur autotrophic bacteria, the inoculation amount being 10%-15% of the reactor body 1 volume. Before inoculation, the bacteria are appropriately diluted and activated to improve their activity and adaptability. After inoculation, close the inlet 101 and outlet 102 of the reactor body 1 and perform internal circulation culture for 24-48 hours to allow the sulfur autotrophic bacteria to attach and grow on the carrier surface.

[0073] S3. Pretreated coal chemical wastewater is introduced into reactor body 1 through inlet 101. The flow rate and water quality of the wastewater are controlled, ensuring a residence time of 1-6 hours within reactor body 1. During the treatment process, an appropriate amount of air is introduced into reactor body 1 through aeration pipe 4 to control the dissolved oxygen concentration at 2-4 mg / L. Simultaneously, parameters such as temperature and pH value within reactor body 1 are monitored in real time and adjusted through the control system to maintain the temperature at 25-35℃ and the pH value at 7.0-8.5.

[0074] S4. The treated wastewater is discharged from the reactor body 1 through the outlet 102. During the drainage process, the quality of the effluent is monitored in real time. When the effluent quality meets the relevant national emission standards, the wastewater is discharged into the environment; if the effluent quality does not meet the emission standards, the wastewater is returned to the reactor body 1 for secondary treatment.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
