Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sulfur disproportionation reactor and reaction system. Background Technology

[0002] Sulfur autotrophic denitrification (SADN) is an autotrophic biological nitrogen removal process that uses elemental sulfur as an electron donor to gradually reduce nitrate to nitrogen. Compared to traditional heterotrophic denitrification, SADN offers advantages such as high nitrogen removal efficiency, low sludge production, no need for carbon source addition, and no carbon dioxide emissions, truly achieving "carbon saving and nitrogen reduction." However, the low solubility and poor bioavailability of elemental sulfur as an electron donor significantly limit the rate of SADN. Sulfur autotrophic disproportionation (SADP) is widely considered an important step in the natural sulfur cycle, a process that converts elemental sulfur into sulfides and sulfates. The reaction of sulfides and elemental sulfur can generate polysulfides, thereby improving the bioavailability of elemental sulfur and significantly increasing the denitrification rate.

[0003] Common sulfur autotrophic and sulfur disproportionation reactors often employ packed bed structures. These reactors typically fill the reactor interior with elemental sulfur as packing material. While structurally simple, they suffer from problems such as reactor clogging and low mass transfer efficiency. Furthermore, sulfur autotrophic denitrification is an anaerobic process, and conventional influent methods introduce oxygen into the feed water, disrupting the anaerobic environment of the reactor and affecting the reaction rate.

[0004] In summary, existing sulfur disproportionation reactors suffer from technical problems such as easy clogging and decreased reaction rate. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a sulfur disproportionation reactor and reaction system to solve the technical problems of easy clogging and decreased reaction rate in the prior art.

[0006] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0007] In one aspect, this application provides a sulfur disproportionation reactor, including a reactor body, a stirring device, an alkali adjustment device, an inlet aeration device, and a pressure buffer device.

[0013] In some embodiments of this application, the stirring device includes a stirrer, a motor, and a speed controller. The motor is mounted on the top cover and is drivenly connected to one end of the stirrer. The other end of the stirrer extends to the bottom of the inner cavity. The speed controller is electrically connected to the motor.

[0014] In some embodiments of this application, the top cover is provided with a feed inlet with a valve, and the side wall of the reactor body is provided with a first water inlet, an air inlet, a first water outlet, an air outlet, an alkali addition port, and a sampling port, each with a valve.

[0037] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a sulfur disproportionation reactor 1 and reaction system to solve the technical problems of easy clogging and decreased reaction rate in the prior art.

[0038] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0039] like Figures 1-2 As shown. In a first aspect, this application provides a sulfur disproportionation reactor 1, including a reactor body 11, a stirring device 12, an alkali adjustment device 13, an inlet water aeration device 14, and a pressure buffer device 15.

[0040] The reactor body 11 has a hollow inner cavity, and a top cover 111 covers the upper part of the inner cavity; the cover is sealed to maintain an anaerobic environment.

[0041] The stirring device 12 is installed on the top cover 111 and extends to the bottom of the inner cavity; it stirs the sludge and sulfur powder in the inner cavity to keep them fluidized.

[0042] The alkali adjustment device 13 includes an acid-base monitoring probe 131 and an alkali source container 132. The acid-base monitoring probe 131 extends into the inner cavity, and the alkali source container 132 is connected to the inner cavity. The acid-base monitoring probe 131 extends into the inner cavity to detect the pH value in real time and feeds back the signal to control the alkali source container 132 to replenish the inner cavity with alkali solution to adjust the pH.

[0043] The inlet aeration device 14 includes an inlet container 141 and a nitrogen cylinder 142. The inlet container 141 is connected to both the inner cavity and the nitrogen cylinder 142, and is sealed with a cap. The inlet aeration device 14 uses the nitrogen cylinder 142 to aerate and deoxygenate the water in the inlet container 141. The solubility of a gas in a liquid (such as dissolved oxygen) is proportional to its partial pressure in the gas phase at the liquid surface. After nitrogen is introduced, the partial pressure of oxygen in the gas phase decreases, forcing dissolved oxygen in the water to escape into the gas phase, thus achieving deoxygenation. Then, anaerobic water is introduced into the reactor inner cavity through the sealed inlet container 141.

[0044] The pressure buffer device 15 is connected to the inner cavity. It serves to stabilize the pressure inside the cavity and together maintain the anaerobic environment of the reactor.

[0045] This application utilizes the stirring device 12 to maintain the sludge in a fluid state within the reactor. The fluidized sludge facilitates uniform mixing with sulfur powder, increasing contact area and time, thus improving mass transfer efficiency. This avoids the clogging issues common with traditional fixed packing materials. The influent aeration device 14 removes dissolved oxygen from the influent, and the sealed lid helps maintain the required anaerobic conditions inside the reactor, promoting the growth and metabolism of sulfur-autotrophic denitrifying microorganisms. The pH monitoring probe 131 in the alkali adjustment device 13 can detect the pH value of the solution in the inner cavity in real time and adjust it promptly through the alkali source container 132 to maintain a suitable reaction pH environment.

[0046] In some embodiments of this application, the stirring device 12 includes a stirrer 121, a motor 122 and a speed regulator 123. The motor 122 is mounted on the top cover 111 and is drivenly connected to one end of the stirrer 121. The other end of the stirrer 121 extends to the bottom of the inner cavity. The speed regulator 123 is electrically connected to the motor 122.

[0047] The motor 122 is fixed to the reactor top cover 111, and its power output end is connected to one end of the agitator 121 via a transmission connection (such as a coupling). The other end of the agitator 121 extends into the bottom of the reactor cavity. The speed controller 123 is electrically connected to the motor 122, and controls the rotational speed of the motor 122 by adjusting the input power or frequency of the motor 122, thereby precisely controlling the rotational speed of the agitator 121 to achieve sufficient contact between the sludge and sulfur powder.

[0048] Electrical energy is converted into mechanical rotational power by motor 122, driving the agitator 121. The addition of speed controller 123 allows for flexible and precise adjustment of the agitation speed according to reaction requirements (such as mass transfer requirements at different stages, microbial growth characteristics, etc.). This not only more effectively achieves sludge fluidization and mixing with sulfur powder, optimizing the mass transfer process, but also avoids energy waste or damage to microorganisms that may result from improper agitation speed, improving the adaptability and efficiency of reactor operation.

[0049] In some embodiments of this application, the top cover 111 is provided with a feed inlet 11a with a valve, and the side wall of the reactor body 11 is provided with a first water inlet 11b, an air inlet, a first water outlet 11c, an air outlet, an alkali addition port 11f, and a sampling port 11d, each with a valve.

[0050] The sampling port 11d can be used for daily effluent monitoring sampling and microbial community sampling, and the air outlet of the air pressure buffer device 15 is sealed and connected to the air outlet.

[0051] In some embodiments of this application, the alkali adjustment device 13 further includes a metering pump 133 and an alkali source pipe 134. The alkali source container 132 is connected to the metering pump 133, and the metering pump 133 is connected to the alkali addition port 11f through the alkali source pipe 134.

[0052] The alkali solution in the alkali source container 132 first flows into the metering pump 133, which precisely controls the amount of alkali solution pumped out each time. Then, the metered amount of alkali solution is delivered to the designated alkali addition port 11f in the reactor cavity through the alkali source pipe 134.

[0053] The introduction of metering pump 133 significantly improves the accuracy and controllability of alkali addition. Metering pump 133 can precisely and quantitatively add alkali solution as needed based on pH changes fed back by acid-base monitoring probe 131, avoiding the problems of over- or under-addition that may occur with manual alkali addition or simple on / off control. This helps to more stably and quickly adjust and maintain the pH value inside the reactor cavity within the optimal reaction range, creating a more optimized chemical environment for sulfur disproportionation and subsequent denitrification reactions, thus improving reaction efficiency and stability.

[0054] In some embodiments of this application, the alkali adjustment device 13 further includes a controller 135, which is signal-connected to the acid-base monitoring probe 131 and the metering pump 133, respectively.

[0055] The pH probe is completely immersed in the liquid inside the reactor cavity, monitoring and transmitting pH signals to the controller 135 in real time. The controller 135 has a preset suitable pH range. When the received pH value is lower than the lower limit of this range, the controller 135 will issue a command to start the metering pump 133, precisely pumping a certain amount of alkaline solution into the reactor cavity, so that the pH value rises back to the suitable range.

[0056] This automated control method enables real-time, closed-loop feedback adjustment of pH value. The pH probe, positioned below the liquid surface, accurately reflects the true pH condition of the reaction solution. The controller 135 automatically determines and triggers the metering pump 133 to add alkali according to a preset range, with rapid response and precise alkali dosage. This completely avoids the lag and inaccuracy of manual monitoring and alkali addition, ensuring that the pH value within the reactor remains stable within the optimal range. This provides the most suitable growth and metabolic environment for sulfur dismutating microorganisms, thereby significantly improving reaction efficiency and the stability and reliability of the system.

[0057] In some embodiments of this application, the water inlet aeration device 14 further includes a water inlet peristaltic pump 143 and a water inlet pipe 144. The water inlet container 141 is connected to the water inlet peristaltic pump 143, and the water inlet peristaltic pump 143 is connected to the first water inlet 11b through the water inlet pipe 144.

[0058] The water, after being deoxygenated by nitrogen aeration, is stored in the inlet container 141. An inlet peristaltic pump 143 is installed at the outlet of the inlet container 141, which precisely extracts the deoxygenated water from the container by squeezing the pump tube. Subsequently, the water is transported through the inlet pipe 144 to the first inlet 11b of the reactor and enters the inner cavity of the reactor.

[0059] A peristaltic pump is a positive displacement pump that provides highly precise and repeatable flow control. This allows for precise adjustment of the influent rate according to reaction requirements, avoiding the adverse effects of flow fluctuations on the reactor environment (such as agitation, mass transfer, and microbial growth). Simultaneously, it ensures a stable and continuous introduction of deoxygenated water into the reactor, maintaining the required anaerobic conditions, which is conducive to the stable and efficient conduct of the reaction.

[0060] In some embodiments of this application, the water inlet aeration device 14 further includes an air valve 145 and an air supply pipe 146. The air valve 145 is located at the outlet of the nitrogen cylinder 142, and the nitrogen cylinder 142 is connected to the water inlet container 141 through the air valve 145 and the air supply pipe 146.

[0061] A gas valve 145 is installed at the outlet of the nitrogen cylinder 142 to control the on / off state and flow rate of nitrogen. One end of a gas supply pipe 146 is connected to the gas valve 145, and the other end extends into or connects to the water inlet container 141. During operation, the gas valve 145 is opened, and nitrogen enters the water inlet container 141 through the gas supply pipe 146, aerating the water inside the container and displacing the dissolved oxygen in the water.

[0062] The installation of air valve 145 makes nitrogen introduction more controllable. Operators can precisely adjust the nitrogen flow rate and introduction time as needed, thereby controlling the aeration intensity and deoxygenation effect. This not only ensures that the influent is sufficiently and effectively deoxygenated, meeting the reactor's requirements for an anaerobic environment, but also avoids the waste or adverse effects on subsequent influent processes that may result from excessive nitrogen introduction. The addition of air valve 145 enhances the flexibility and precision of the influent aeration process.

[0063] In some embodiments of this application, a water outlet device 16 is also included, which includes a water outlet container 161, a water outlet peristaltic pump 162, and a water outlet pipe 163. The water outlet peristaltic pump 162 is connected to the first water outlet 11c, and the water outlet peristaltic pump 162 is connected to the water outlet container 161 through the water outlet pipe 163.

[0064] One end of the peristaltic pump 162 is connected to the first outlet 11c of the reactor to extract liquid from the reactor cavity. The other end of the pump delivers the liquid to the outlet container 161 for collection or further treatment via the outlet pipe 163.

[0065] The effluent process is controlled by a peristaltic pump 162, similar to the influent process, providing precise and repeatable flow control. This ensures that the liquid level within the reactor is stably maintained at the set level, avoiding level fluctuations caused by unstable effluent flow rates, thus guaranteeing good hydraulic residence time and a stable operating environment within the reactor. Precise flow control also helps maintain good mixing and mass transfer within the reactor, ensuring continuous and efficient reaction. Furthermore, the peristaltic pump is reliable, does not easily contaminate the fluid, and is suitable for treating biological reaction systems.

[0066] The reactor body 11 and top cover 111 are made of plexiglass. Plexiglass was chosen as the material for the reactor body 11 and top cover 111 primarily due to its excellent transparency for easy observation, good processing performance, and relatively low cost. This facilitates direct monitoring of the internal reaction process.

[0067] The operating procedure for this reaction apparatus is as follows:

[0068] Step 1: Place the reactor flat on a table or the ground. Add the sludge to be acclimated to the reactor, cover it with the top cover 111, and tighten the screws to ensure a good seal. Add sulfur powder into the reactor through the feed inlet 11a on the top cover 111, and tighten the feed inlet 11a with the cover. Connect the reactor's first inlet 11b to the inlet peristaltic pump 143 and the inlet container 141 using the inlet pipe 144. Connect the reactor's first outlet 11c to the outlet peristaltic pump 162 and the outlet container 161 using the outlet pipe 163. Seal the first vent 11e to the pressure buffer device 15. Keep the valves of the first vent 11e, first inlet 11b, and first outlet 11c open. Connect the alkali source container 132 and the alkali addition port 11f using the metering pump 133 and the alkali source pipe 134, and connect the controller 135 to the metering pump 133. Open the alkali addition port 11f.

[0069] Step 2: Before starting, confirm that all connections on the top cover 111 are strictly sealed and there is no air leakage. The valves of the second water inlet 11h, the second water outlet 11i, the sampling port 11d, and the second air outlet 11g are all closed.

[0070] Step 3: After preparing new feed water in the feed water tank, open the gas valve 145 of the nitrogen cylinder 142 and introduce nitrogen gas into the feed water tank for 10-20 minutes. Then, seal the feed water tank to remove dissolved oxygen from the feed water, maintain anaerobic feed water, and avoid impacting the anaerobic environment of the reactor. After a certain period of time, pump the feed water or wastewater prepared in the feed water tank into the reactor body 11 in one go, ensuring that the liquid level is below the first gas outlet 11e, and leaving appropriate space above the liquid level to prevent overflow during stirring.

[0071] Step 4: Turn on the agitator 121 and motor 122, adjust the speed controller 123 to a suitable speed, stop agitating after the set hydraulic residence time is reached, allow the water to settle for 20 minutes, and then drain some of the water. After draining the water, repeat steps 3 and 4.

[0072] Secondly, this application also provides a sulfur disproportionation reaction system, including a peristaltic pump and at least two sulfur disproportionation reactors 1 as described in any embodiment of the first aspect, wherein the peristaltic pump is connected to two of the sulfur disproportionation reactors 1 respectively.

[0073] Once the first reactor completes the sulfur disproportionation reaction and produces effluent containing sulfides, a peristaltic pump is activated to extract this effluent from the outlet of the first reactor and precisely deliver it to the inlet of the second reactor. In the second reactor, the introduced sulfides react with the sulfur powder present therein to generate polysulfides. Simultaneously, these sulfides provide electron donors for the sulfur autotrophic denitrifying microorganisms within the reactor.

[0074] In some embodiments of this application, the reactor body 11 is further provided with a second inlet 11h and a second outlet 11i, wherein the second outlet 11i of one reactor body 11 is connected to the second inlet 11h of the other reactor body 11 via the connecting peristaltic pump.

[0075] This tandem design achieves synergistic effects between the two reaction processes. First, the sulfides produced in the first reactor are introduced into the second reactor to react with sulfur powder, generating polysulfides. This helps break down any passivation layer that may form on the surface of the sulfur powder, improving its bioavailability and accelerating the subsequent sulfur autotrophic denitrification reaction, thus increasing denitrification efficiency. Second, the sulfides themselves act as key electron donors in the sulfur autotrophic denitrification process, directly supporting the metabolic activities of denitrifying microorganisms. This method of using the product of the preceding reaction as a raw material and electron donor for the subsequent reaction not only improves the utilization efficiency of sulfur resources but also significantly enhances the denitrification load and processing capacity of the entire system, achieving efficient resource recycling. The use of a peristaltic pump ensures precise control of water flow, making material transfer stable and reliable.

[0076] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include:

[0077] This invention employs mechanical stirring to achieve full contact between sludge, sulfur powder, and wastewater, improving the solubility of sulfur powder in water and facilitating mass transfer. It also avoids the problem of packing blockage in packed bed reactors. Furthermore, aeration and sealing before the influent enters the reactor prevent the presence of oxygen in the influent, thus maintaining an anaerobic environment. This invention can also be used as a sulfur autotrophic denitrification reactor. Using the effluent from sulfur disproportionation reactor 1 as part of the influent for sulfur autotrophic denitrification can accelerate the denitrification rate and increase the nitrogen treatment load.

[0078] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0079] The specific embodiments described above do not constitute a limitation on the scope of protection of this application.
