Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a carbon-neutral water purification device for regulating the metabolic activity of microorganisms. Background Art

[0002] Short-chain fatty acids are one of the degradation products of organic matter under anaerobic conditions and are used by anaerobic microorganisms as energy and carbon sources for growth. Short-chain fatty acids have the function of nitrogen and phosphorus removal. Therefore, in the process of microbial degradation of organic matter in sewage, the content of short-chain fatty acids is usually added to sewage to improve the sewage treatment efficiency and reduce the emissions of greenhouse gases such as CO2, NO, and N2O.

[0003] At present, when sewage treatment plants purify urban sewage, acetic acid is usually added to sewage as a carbon source required for microbial nitrogen and phosphorus removal. However, acetic acid is easily utilized by methanogens and converted into methane, and the greenhouse effect of methane is 120 times that of carbon dioxide, which is not conducive to the carbon emission reduction goal. However, propionic acid is different. This is because the oxidation decomposition rate of PHV is close to the rate of electron donors required for nitrogen removal and phosphorus uptake. Therefore, after propionic acid is utilized by microorganisms, the methanogenesis process can be effectively avoided, and carbon neutrality and carbon emission reduction of sewage treatment plants can be achieved. Therefore, if the content of organic matter converted into propionic acid in sewage treatment can be increased and then converted into a specific intracellular polymer of functional microorganisms - polyhydroxyvalerate (PHV), the sewage treatment efficiency can be significantly improved and the emissions of greenhouse gases such as CO2, NO, and N2O can be reduced. The key to realizing this process is to adjust the sewage treatment process to be weakly alkaline, that is, the pH value reaches 7.6 - 8.0. Summary of the Utility Model

[0004] In order to adjust the sewage treatment process to be weakly alkaline and reduce greenhouse gas emissions, the present application provides a carbon-neutral water purification device for regulating the metabolic activity of microorganisms.

[0005] The carbon-neutral water purification device for regulating the metabolic activity of microorganisms provided by the present application adopts the following technical solutions:

[0006] A carbon-neutral water purification device for regulating the metabolic activity of microorganisms includes a pool body, and the pool body includes a crushing pool, a reaction pool, and a fermentation pool. The reaction pool is located between the crushing pool and the fermentation pool. One end of the reaction pool is communicated with the crushing pool, and the other end of the reaction pool is communicated with the fermentation pool. A micro-nano bubble generator is fixedly arranged on the side wall of the reaction pool, and the output end of the micro-nano bubble generator is communicated with the reaction pool. An alkali liquid adding tank is fixedly arranged on the reaction pool, an alkali liquid adding pipe is communicated with the alkali liquid adding tank, and a solenoid valve is arranged on the alkali liquid adding pipe. The solenoid valve is used to control the on-off of the alkali liquid adding pipe. A sewage adding pipe is communicated with the side of the crushing pool away from the reaction pool.

[0007] By adopting the above technical solution, sewage is introduced into the crushing tank through the sewage addition pipe. Large impurities in the sewage flow into the reaction tank after being broken in the crushing tank, and then the micro-nano bubble generator is started. The micro-nano bubble generator produces micro-nano scale bubbles in the sewage. The sewage flows into the fermentation tank after being mixed with the micro-nano scale bubbles in the reaction tank. Since the micro-nano scale bubbles have a large specific surface area, a slow rising speed and are easily negatively charged, hydroxyl free radicals with super strong oxidation effect are generated instantaneously when the micro-nano scale bubbles burst. The hydroxyl free radicals degrade the pollutants in the sewage that are difficult to oxidize and decompose. At the same time, the hydroxyl free radicals promote the generation of short-chain fatty acids by microorganisms in the sewage. At the same time, the solenoid valve is opened, so that the alkali liquid in the alkali liquid addition tank flows into the reaction tank through the alkali liquid addition pipe, adjusting the sewage treatment process to be weakly alkaline, promoting the generation of propionic acid in the sewage and reducing greenhouse gas emissions.

[0008] Preferably, an acid-base detector is fixedly arranged in the reaction tank, and the acid-base detector is used to detect the acidity and alkalinity in the reaction tank.

[0009] By adopting the above technical solution, the acid-base detector detects the acidity and alkalinity of the sewage in the reaction tank. When the acidity and alkalinity is lower than 7.6, the solenoid valve is opened, and the alkali liquid is added to the sewage to increase the acidity and alkalinity of the sewage. When the acidity and alkalinity is higher than 8.0, the solenoid valve is closed to reduce the acidity and alkalinity of the sewage, so as to maintain the acidity and alkalinity of the sewage in the reaction tank between 7.6 and 8.0.

[0010] Preferably, an overflow weir is fixedly arranged between the crushing tank and the reaction tank, and a partition weir is fixedly arranged between the reaction tank and the fermentation tank. The height of the overflow weir is lower than the height of the partition weir.

[0011] By adopting the above technical solution, sewage is introduced into the crushing tank through the sewage addition pipe. When the sewage in the crushing tank accumulates to a sufficient height, the sewage in the crushing tank overflows the overflow weir and flows into the reaction tank from above the overflow weir, achieving the effect of the sewage in the crushing tank flowing into the reaction tank.

[0012] Preferably, a pumping seat is fixedly arranged on the fermentation tank, a water pump is fixedly arranged on the pumping seat, the input end of the water pump is connected with a water inlet pipe, one end of the water inlet pipe far away from the water pump is communicated with the reaction tank, the output end of the water pump is connected with a water outlet pipe, and one end of the water outlet pipe far away from the water pump is communicated with the fermentation tank.

[0013] By adopting the above technical solution, the water pump is started. The water pump pumps the sewage in the reaction tank into the water inlet pipe, and then pumps the sewage from the water inlet pipe into the water outlet pipe. The sewage is discharged into the fermentation tank through the sewage pipe, thus achieving the effect of discharging the sewage in the reaction tank into the fermentation tank.

[0014] Preferably, a mounting plate is fixedly arranged between the overflow weir and the partition weir. A stirring motor is fixedly arranged on the mounting plate. The output shaft of the stirring motor penetrates through the mounting plate. A stirring rod is fixedly arranged on the end wall of the output shaft of the stirring motor. The stirring rod is located in the reaction tank, and a plurality of stirring blades are fixedly arranged on the stirring rod.

[0015] By adopting the above technical solution, when the stirring motor is started, the stirring motor drives the stirring rod to rotate. The rotation of the stirring rod drives the stirring blades to rotate. The rotation of the stirring blades drives the hydroxyl radicals and the lye generated by the micro-nano bubble generator to move, so that the hydroxyl radicals and the lye are evenly distributed in the sewage, making the sewage treatment process weakly alkaline.

[0016] Preferably, a set of crushing motors are fixedly arranged on the side wall of the crushing tank. The output shafts of the crushing motors penetrate through the side wall of the crushing tank. A crushing roller is fixedly arranged at one end of the output shaft of the crushing motor located in the crushing tank. The end of the crushing roller far away from the crushing motor is rotatably connected to the inner wall of the crushing tank. The crushing roller is located below the sewage adding pipe.

[0017] By adopting the above technical solution, when the crushing motor is started, the crushing motor drives the crushing roller to rotate. The crushing roller crushes the large impurities in the sewage. The sewage after crushing the impurities flows into the reaction tank. Since the surface area of the impurities in the sewage increases, the contact area between the impurities and the hydroxyl radicals increases, thereby increasing the reaction rate between the impurities and the hydroxyl radicals.

[0018] Preferably, a mounting seat is fixedly arranged on the side wall of the fermentation tank. A glycogen adding tank and a glycogen delivery pump are fixedly arranged on the mounting seat. The input end of the glycogen delivery pump is communicated with the glycogen adding tank, and the output end of the glycogen delivery pump is communicated with the fermentation tank.

[0019] By adopting the above technical solution, when the glycogen delivery pump is started, the glycogen delivery pump adds the glycogen in the glycogen adding tank into the fermentation tank, accelerating the fermentation speed of the short-chain fatty acids in the sewage.

[0020] Preferably, a feed pipe is communicated with the input end of the glycogen delivery pump. One end of the feed pipe far away from the glycogen delivery pump is communicated with the glycogen adding tank. A discharge pipe is communicated with the output end of the glycogen delivery pump. One end of the discharge pipe far away from the glycogen delivery pump is communicated with the fermentation tank.

[0021] By adopting the above technical solution, when the glycogen delivery pump is started, the glycogen in the glycogen adding tank is pumped from the feed pipe into the discharge pipe by the glycogen delivery pump, and the glycogen in the discharge pipe is injected into the fermentation tank.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] The following will further describe the present application in detail with reference to the attached Figures 1-4 drawings.

[0032] An embodiment of the present application discloses a carbon-neutral water purification device for regulating the metabolic activity of microorganisms. Refer to Figure 1 and Figure 2, which includes a pond body 1. The pond body 1 includes a crushing pond 11, a reaction pond 12 and a fermentation pond 13. The reaction pond 12 is located between the crushing pond 11 and the fermentation pond 13. A sewage adding pipe 111 is installed on one side of the crushing pond 11 away from the reaction pond 12, and the sewage adding pipe 111 penetrates through the side wall of the crushing pond 11. An overflow weir 4 is installed between the crushing pond 11 and the reaction pond 12, and a partition weir 5 is fixedly arranged between the reaction pond 12 and the fermentation pond 13. The height of the overflow weir 4 is lower than the height of the partition weir 5. A pumping seat 61 is installed on the fermentation pond 13, and a water pump 6 is installed on the pumping seat 61. An inlet pipe 62 is installed at the input end of the water pump 6. One end of the inlet pipe 62 away from the water pump 6 is communicated with the reaction pond 12. An outlet pipe 63 is installed at the output end of the water pump 6. One end of the outlet pipe 63 away from the water pump 6 is communicated with the fermentation pond 13. A micro-nano bubble generator 2 is installed on the side wall of the reaction pond 12. The output end of the micro-nano bubble generator 2 penetrates through the side wall of the reaction pond 12, and the output end of the micro-nano bubble generator 2 is communicated with the reaction pond 12. An alkali solution adding tank 3 is installed on the reaction pond 12. An alkali solution adding pipe 31 is communicated at the bottom of the alkali solution adding tank 3. An electromagnetic valve 32 is installed on the alkali solution adding pipe 31, and the electromagnetic valve 32 is used to control the on-off of the alkali solution adding pipe 31. Sewage is introduced into the crushing pond 11 through the sewage adding pipe 111, and large impurities in the sewage are broken in the crushing pond 11. When the sewage in the crushing pond 11 accumulates to a sufficient height, the sewage in the crushing pond 11 overflows the overflow weir 4 and flows into the reaction pond 12 from above the overflow weir 4. At the same time, the micro-nano bubble generator 2 is started. The micro-nano bubble generator 2 produces micro-nano scale bubbles in the sewage. Since the micro-nano scale bubbles have a large specific surface area, a slow rising speed and are easily negatively charged, hydroxyl radicals with super strong oxidation effects are generated instantaneously when the micro-nano scale bubbles burst. The hydroxyl radicals are mixed with the sewage. The water pump 6 pumps the sewage mixed with hydroxyl radicals in the reaction pond 12 into the inlet pipe 62, and then the water pump 6 pumps the sewage from the inlet pipe 62 into the outlet pipe 63, and the sewage is discharged into the fermentation pond 13 through the sewage pipe. The hydroxyl radicals degrade the pollutants in the sewage that are difficult to oxidize and decompose. At the same time, the hydroxyl radicals promote the generation of short-chain fatty acids by microorganisms in the sewage. At the same time, the electromagnetic valve 32 is opened, so that the alkali solution in the alkali solution adding tank 3 flows into the reaction pond 12 through the alkali solution adding pipe 31, adjusting the sewage treatment process to be weakly alkaline, promoting the generation of propionic acid in the sewage, promoting the removal of nitrogen and phosphorus in the sewage, and reducing greenhouse gas emissions. The effect of improving the sewage treatment efficiency is achieved, and the emissions of greenhouse gases such as CO2, NO, and N2O are reduced.

[0033] In order to make the sewage treatment process weakly alkaline, refer to Figure 1 and Figure 2, a pH detector is installed in the reaction tank. The pH detector is used to detect the pH value in the reaction tank. When the pH value is lower than 7.6, the solenoid valve opens, and the alkali solution is added to the sewage to increase the pH value of the sewage. When the pH value is higher than 8.0, the solenoid valve closes to lower the pH value of the sewage. Thus, the pH value of the sewage in the reaction tank is maintained between 7.6 and 8.0.

[0034] To ensure that both hydroxyl radicals and the alkali solution are fully mixed with the sewage, refer to Figure 2 and Figure 3 , an installation plate 71 is installed between the overflow weir 4 and the partition weir 5. One end of the installation plate 71 is connected to the side wall of the partition weir 5, and the other end of the installation plate 71 is connected to the side wall of the overflow weir 4. A stirring motor 7 is installed on the installation plate 71, and the output shaft of the stirring motor 7 penetrates through the installation plate 71. A stirring rod 72 is installed on the end wall of the output shaft of the stirring motor 7. The stirring rod 72 is located in the reaction tank 12, and several stirring blades 73 are installed on the side wall of the stirring rod 72. When the stirring motor 7 is started, the stirring motor 7 drives the stirring rod 72 to rotate, and the rotation of the stirring rod 72 drives the stirring blades 73 to rotate. The rotation of the stirring blades 73 enables both hydroxyl radicals and the alkali solution to be fully mixed with the sewage, and thus hydroxyl radicals and the alkali solution are evenly distributed in the sewage.

[0035] To increase the reaction rate between impurities and hydroxyl radicals, refer to Figures 2 to 4 , a set of crushing motors 8 are installed on the side wall of the crushing tank 11, and the output shafts of the crushing motors 8 penetrate through the side wall of the crushing tank 11. A crushing roller 81 is installed at one end of the output shaft of the crushing motor 8 located inside the crushing tank 11. The end of the crushing roller 81 away from the crushing motor 8 is rotatably connected to the inner wall of the crushing tank 11, and the crushing roller 81 is located below the sewage addition pipe 111. When the crushing motor 8 is started, the crushing motor 8 drives the crushing roller 81 to rotate, and the crushing roller 81 rotates to crush the large pieces of impurities in the sewage. The sewage after crushing the impurities flows into the reaction tank 12. Since the surface area of the impurities in the sewage increases after crushing, the contact area between the impurities and hydroxyl radicals increases, thereby increasing the reaction rate between the impurities and hydroxyl radicals.

[0036] To accelerate the fermentation rate of short-chain fatty acids in the sewage, refer to Figures 2 to 4, a mounting seat 91 is installed on the side wall of the fermentation tank 13, and a glycogen addition tank 92 and a glycogen delivery pump 9 are installed on the mounting seat 91. A feed pipe 93 is installed on the input end of the glycogen delivery pump 9. One end of the feed pipe 93 is in communication with the input end of the glycogen delivery pump 9, and the other end of the feed pipe 93 is in communication with the glycogen addition tank 92. A discharge pipe 94 is installed on the output end of the glycogen delivery pump 9. One end of the discharge pipe 94 is in communication with the output end of the glycogen delivery pump 9, and the other end of the discharge pipe 94 is in communication with the fermentation tank 13. When the glycogen delivery pump 9 is started, the glycogen in the glycogen addition tank 92 is pumped into the discharge pipe 94 by the glycogen delivery pump 9 through the feed pipe 93, and the glycogen in the discharge pipe 94 is injected into the fermentation tank 13. The glycogen is mixed with the sewage in the fermentation tank 13 to increase the internal carbon source of the sewage and accelerate the fermentation rate of short-chain fatty acids in the sewage.

[0037] The implementation principle of a carbon-neutral water purification device for regulating the metabolic activity of microorganisms in an embodiment of the present application is as follows: Sewage is introduced into the pulverization tank 11 through the sewage addition pipe 111, and large impurities in the sewage are broken by the pulverization roller 81 in the pulverization tank 11. When the sewage in the pulverization tank 11 accumulates to a sufficient height, the sewage in the pulverization tank 11 overflows the overflow weir 4 and flows into the reaction tank 12 from above the overflow weir 4. At the same time, the micro-nano bubble generator 2 is started, and the micro-nano bubble generator 2 produces micro-nano scale bubbles in the sewage. Since the micro-nano scale bubbles have a large specific surface area, a slow rising speed and are easily negatively charged, hydroxyl radicals with super-oxidizing effects are generated at the moment when the micro-nano scale bubbles burst. The sewage in the reaction tank 12 is mixed with the hydroxyl radicals generated by the micro-nano scale bubbles. The hydroxyl radicals degrade pollutants in the sewage that are difficult to oxidize and decompose, and at the same time, the hydroxyl radicals promote the generation of short-chain fatty acids by microorganisms in the sewage. At the same time, the solenoid valve 32 is opened, so that the alkali solution in the alkali solution addition tank 3 flows into the reaction tank 12 through the alkali solution addition pipe 31, adjusting the sewage treatment process to be weakly alkaline and promoting the generation of propionic acid in the sewage. The water pump 6 pumps the sewage mixed with hydroxyl radicals and alkali solution in the reaction tank 12 into the fermentation tank 13, and the glycogen delivery pump 9 adds the glycogen in the glycogen addition tank 92 into the fermentation tank 13 to accelerate the fermentation rate of short-chain fatty acids in the sewage. Propionic acid promotes the removal of nitrogen and phosphorus in the sewage and reduces greenhouse gas emissions, achieving the effect of improving the sewage treatment efficiency and reducing the emissions of greenhouse gases such as CO2, NO, and N2O.

[0038] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
