Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a device and a method for enhanced sewage treatment based on quorum sensing. Background Art

[0002] Using microorganisms to purify sewage is a biological treatment technology that mainly relies on the metabolism of microorganisms to decompose and transform pollutants in sewage to purify the sewage. Microorganisms play the role of "cleaners" in this process, converting pollutants such as organic matter and nutrients in sewage into harmless carbon dioxide, water and the biomass of the microorganisms themselves.

[0003] The growth and metabolism of microorganisms require suitable environmental conditions, such as temperature, pH value, dissolved oxygen, etc. For example, the metabolic activity of most microorganisms will be significantly reduced when the temperature is below 10°C or above 40°C; if the pH value of sewage is too high or too low, it will also affect the survival and metabolism of microorganisms.

[0004] The existing sewage biological treatment equipment has low utilization efficiency of biological organisms, the microbial population is relatively single, and there are many types of sewage. The adaptability of biological organisms is limited, resulting in unsatisfactory treatment results, which need further improvement and optimization. Summary of the invention

[0026] The dosing and conveying pipes are connected to the inside of the microbial culture containing shell through a conveying pump.

[0027] Note: It is convenient to transport the microbial solution cultured in the microbial culture containing shell to the sewage treatment ring channel for sewage purification treatment.

[0032] Note: During the relative movement of the light shielding control shell and the light shielding fixed shell, by controlling the overlapping degree of the light transmission holes and the light transmission matching holes, the light transmission amount passing through the light transmission holes is further controlled.

[0033] Preferably, an aeration supply mechanism is provided at the inner bottom of the sewage treatment ring channel. The aeration supply mechanism includes an aeration supply pipe fixed at the inner bottom of the sewage treatment ring channel and extending radially along the main body support shell. A plurality of aeration output spherical shells are fixedly connected and communicated through supply short pipes on the upper side of the aeration supply pipe;

[0034] A plurality of aeration output nozzles connected to the inside are fixed on the outside of the aeration output spherical shell, and a bubble differentiation mesh cover is arranged to surround the outside of the aeration output spherical shell.

[0035] Note: The aeration supply mechanism is used to continuously aerate the sewage to maintain the oxygen dissolution amount in the water body. The small bubbles discharged from each aeration output nozzle will be dispersed into a plurality of smaller bubbles after passing through the bubble differentiation mesh cover, which is convenient for better full contact with the water body.

[0036] Preferably, a method for enhancing sewage treatment based on quorum sensing, based on the above-mentioned device for enhancing sewage treatment based on quorum sensing, includes the following steps:

[0037] S1. Input of sewage to be treated:

[0038] The sewage to be treated is injected into the sewage treatment ring channel through the water inlet pipe, and the input amount of the sewage is 70% of the total volume of the sewage treatment ring channel;

[0039] S2. Temporary storage and cultivation of microbial solution:

[0040] The microbial solution for purifying sewage is temporarily stored and cultivated in the microbial cultivation mechanism:

[0041] Input the microbial solution and the sewage sample to be treated into each microbial culture containing tube shell, keep the temperature in the microbial culture containing tube shell suitable, and provide sufficient dissolved oxygen in the microbial culture containing tube shell to maintain the microbial activity, so as to directionally screen out the microbial population suitable for this sewage purification;

[0042] The output end of the gas conveyor is connected to the inside of the air supply flow pipe through a pipeline. Use the gas conveyor to transport air into the air supply flow pipe, and the air then discharges from the exhaust micropores at the lower end of the air supply flow pipe;

[0043] Use the fiber optic sunlight concentrator of the existing technology to collect sunlight. The fiber optic output end of the fiber optic sunlight concentrator is fixed in each fiber optic fixed containing tube. The sunlight conducted by the optical fiber irradiates at the output end. Use the light scattering lens to adjust the scattering range of the sunlight so that the scattering range of the sunlight irradiates at the light transmission hole, and the sunlight irradiates on the diffusing film and is evenly scattered on the microbial culture containing tube shell;

[0044] Use the photothermal energy to keep the temperature in the microbial culture containing tube shell at a suitable temperature for the microorganisms;

[0045] Use the light transmission control driving rod to drive the light transmission control lifting cylinder to lift and lower. The light transmission control lifting cylinder drives the light shielding control tube shell to lift and lower together. During the relative movement of the light shielding control tube shell and the light shielding fixed tube shell, by controlling the overlap degree of the light transmission hole and the light transmission matching hole, the light transmission amount passing through the light transmission hole is further controlled;

[0046] To realize the regulation of the temperature in the microbial culture containing tube shell;

[0047] S3. Initially add the microbial solution to the sewage:

[0048] Put the microbial solution in the microbial culture containing tube shell into the sewage to be treated in the sewage treatment ring channel, and use the decomposition effect of the microorganisms to purify the sewage;

[0049] The dosage of the microbial solution is 0.5-2% of the total volume of the sewage;

[0050] At the same time, use the aeration supply mechanism to continuously aerate the sewage to maintain the dissolved oxygen in the water body. Use the air conveyor of the existing technology to introduce air into each aeration supply pipe. The air in the aeration supply pipe enters the aeration output spherical shell through the supply short pipe, and the air in the aeration output spherical shell then discharges from each aeration output nozzle to form small bubbles. The small bubbles will disperse into multiple smaller bubbles after passing through the bubble differentiation mesh cover. The bubbles are in full contact with the water body during the rising process to supplement the dissolved oxygen in the water body;

[0051] S4. Continuously purify the water body using the decomposition effect of the microorganisms

[0052] Part of the microorganisms added to the sewage are dispersed in the water body, and part of them are concentrated and attached to the surfaces of each microbial attachment plate. During the flow of the sewage, it continuously passes through the sewage purification flow-through shell and contacts these microorganisms, enabling the water body to fully contact the microorganisms, and then realizing the purification of the water body by the decomposition of the microorganisms.

[0053] The circulation driving mechanism is used to drive the water body in the sewage treatment ring channel to continuously flow. All the one-way flow resistance partitions are installed on the same side of the circulation driving plate, and the side with the one-way flow resistance partitions installed is the "back water side", and the other side is the "front water side".

[0054] The rotation range of the circulation driving plate rotating around the circulation driving support ring is °.

[0055] The process of the circulation driving plate moving in the same direction as the water flow is the "driving stroke", and the process of the circulation driving plate moving in the opposite direction to the water flow is the "reset stroke".

[0056] The inner rod of the circulation driving telescopic rod extends and retracts to drive the circulation driving plate to rotate reciprocally around the circulation driving support ring, so as to realize the "driving stroke" and the "reset stroke".

[0057] Taking the top view as an example, at this time, the clockwise direction is the driving direction of the water flow. The process of the circulation driving plate rotating clockwise around the circulation driving support ring is the "driving stroke", and the process of the circulation driving plate rotating counterclockwise around the circulation driving support ring is the "reset stroke".

[0058] During the "driving stroke" of the circulation driving plate, the circulation driving plate moves in the same direction as the water flow, but the movement speed of the circulation driving plate is greater than the water flow speed. Under the action of the water flow resistance, the "back water side" of the circulation driving plate makes each one-way flow resistance partition closely contact the "back water side" of the circulation driving plate, and the one-way flow resistance partition seals the circulation one-way flow groove at this time.

[0059] During the "reset stroke" of the circulation driving plate, the circulation driving plate moves in the opposite direction to the water flow. Under the impact of the water flow, each one-way flow resistance partition rotates around the axis of the rotating shaft connection hole, making the circulation one-way flow groove in a conducting state, enabling the water flow of the circulation to smoothly pass through each circulation one-way flow groove. The one-way flow resistance partition acts as a one-way valve for the circulation one-way flow groove.

[0060] During the "driving stroke", the one-way flow resistance partition seals the circulation one-way flow groove, enabling the whole circulation driving plate to push the water body to flow in the clockwise direction. During the "reset stroke", the flowing water body can smoothly pass through each circulation one-way flow groove, reducing the deceleration effect of the circulation driving plate on the water body.

[0061] The circulation drive board continuously repeats the "driving stroke" and "reset stroke" under the drive of the circulation drive telescopic rod, thereby continuously driving the water body in the sewage treatment loop channel to flow in a clockwise direction;

[0062] S5. Use the microorganism monitoring mechanism to continuously monitor the dynamic changes of the microorganism population:

[0063] The quorum sensing signal molecules of bacteria can be accurately monitored through each dispersedly arranged quorum sensing signal sensor;

[0064] During the working process of each quorum sensing signal sensor, microorganisms will continuously attach to its surface, and the suspended pollutants in the water body will also continuously attach to the surface of the quorum sensing signal sensor. The sensor cleaning mechanism is used to clean each quorum sensing signal sensor to ensure the accuracy of the quorum sensing signal sensor;

[0065] The inner rod of the cleaning drive rod extends and retracts to drive the cleaning moving cylinder to reciprocate along the axis of the cleaning support cylinder. The cleaning moving cylinder drives the sensor cleaning ring to reciprocate together. The cleaning brush on the inner side of the sensor cleaning ring is used to remove the microorganisms and pollutants attached to the surface of the quorum sensing signal sensor, realizing the cleaning effect on the quorum sensing signal sensor;

[0066] S6. Compensate and add microorganism solution to the sewage:

[0067] According to the monitoring results of the quorum sensing signal sensor, determine the state of the microorganism population in the sewage. When the activity of the microorganism population decreases, the microorganism solution in the microorganism culture containing tube shell is transported to the sewage treatment loop channel to compensate and add the microorganism solution to the sewage, and the sewage is continuously purified by the decomposition of the microorganisms;

[0068] S7. Output of the purified sewage:

[0069] The purified sewage can be uniformly discharged from the outlet pipe.

[0070] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0071] 1. The structure of the present invention is reasonably designed, with accurate quorum sensing signal monitoring ability. Each dispersedly arranged quorum sensing signal sensor can accurately monitor the signal, and the monitoring results of multiple quorum sensing signal sensors can compensate and correct each other to ensure the accuracy of the data;

[0072] At the same time, the sensor cleaning mechanism is used to clean each quorum sensing signal sensor to remove the microorganisms and pollutants attached to the surface of the quorum sensing signal sensor to ensure the accuracy of the quorum sensing signal sensor;

[0073] 2. The operation of the present invention is convenient, and it is equipped with an efficient microbial culture and dosing system. First, suitable microbial populations for purifying specific sewage water quality are cultured in each simulation, and then the microbial populations are accurately dosed into the sewage through each dosing and conveying pipe, and the water body is purified by the decomposition action of the microbial populations.

[0074] 3. The present invention uses a circulation driving mechanism to drive the continuous flow of the water body in the sewage treatment loop channel, making the microorganisms in the water body more evenly dispersed, which is beneficial to improving the microbial decomposition efficiency. At the same time, the continuously flowing water body can fully contact the microbial populations attached to the surfaces of each microbial attachment plate, thereby quickly purifying the water body.

[0075] 4. The light control mechanism of the present invention uses a fiber optic sunlight introducer to collect sunlight, and then conducts the sunlight through optical fibers. The sunlight is used to irradiate the microbial culture containing tube shell, and the photothermal energy is used to keep the temperature in the microbial culture containing tube shell at the appropriate temperature for the microorganisms.

[0119] Inject the sewage to be treated into the sewage treatment ring channel 100 through the water inlet pipe 101. The input amount of the sewage is 70% of the total volume of the sewage treatment ring channel 100;

[0120] S2. Temporarily store and culture the microbial solution:

[0121] Temporarily store and culture the microbial solution for purifying sewage in the microbial culture mechanism 40:

[0122] Input the microbial solution and the sewage sample to be treated into each microbial culture housing shell 41, keep a suitable temperature inside the microbial culture housing shell 41, and provide sufficient dissolved oxygen in the microbial culture housing shell 41 to maintain the microbial activity, so as to directionally screen out the microbial population suitable for this sewage purification;

[0123] The output end of the gas conveyor is connected to the inside of the air supply circulation pipe 42 through a pipeline. Use the gas conveyor to transport air into the air supply circulation pipe 42, and the air is then discharged from the exhaust micropores at the lower end of the air supply circulation pipe 42;

[0124] Use the fiber optic sunlight concentrator of the existing technology to collect sunlight. The fiber optic output end of the fiber optic sunlight concentrator is fixed in each fiber optic fixed housing 4322. The sunlight conducted by the optical fiber irradiates at the output end. Use the light scattering lens 4323 to adjust the scattering range of the sunlight, so that the scattering range of the sunlight irradiates at the light transmission hole 4330, and the sunlight irradiates on the diffusing film and is evenly scattered on the microbial culture housing shell 41;

[0125] Use the photothermal energy to keep the temperature inside the microbial culture housing shell 41 at a suitable temperature for the microorganisms;

[0126] Use the light transmission control drive rod 437 to drive the light transmission control lifting cylinder 436 to lift and lower. The light transmission control lifting cylinder 436 drives the light shielding control housing 434 to lift and lower together. During the relative movement between the light shielding control housing 434 and the light shielding fixed housing 433, by controlling the overlap degree of the light transmission hole 4330 and the light transmission matching hole 4340, the light transmission amount passing through the light transmission hole 4330 is further controlled;

[0127] To realize the regulation of the temperature inside the microbial culture housing shell 41;

[0128] S3. Initially add the microbial solution to the sewage:

[0129] Transport the microbial solution in the microbial culture housing shell 41 to each dosing delivery pipe 401. The microbial solution in the dosing delivery pipe 401 is then discharged from the microbial dosing nozzle 402 and dispersed and mixed in the sewage to be treated in the sewage treatment loop channel 100, and use the decomposition effect of the microorganisms to purify the sewage;

[0130] The dosing amount of the microbial solution is 0.5 - 2% of the total volume of the sewage;

[0131] Meanwhile, the aeration supply mechanism 50 is used to continuously aerate the sewage to maintain the dissolved oxygen content in the water body. The air conveyor of the existing technology is used to introduce air into each aeration supply pipe 51. The air in the aeration supply pipe 51 enters the aeration output spherical shell 52 through the supply short pipe 510. The air in the aeration output spherical shell 52 is then discharged from each aeration output nozzle 521 to form small bubbles. After passing through the bubble differentiation mesh cover 53, the small bubbles will be dispersed into multiple tinier bubbles. The bubbles are in full contact with the water body during the rising process, supplementing the dissolved oxygen content in the water body;

[0132] S4. Continuously purify the water body by the decomposition of microorganisms

[0133] Part of the microorganisms added to the sewage are dispersed in the water body, and the other part is concentrated and attached to the surfaces of the respective microorganism attachment plates 23. During the flow of the sewage, it continuously passes through the sewage purification flow-through shell 22 and contacts these microorganisms, enabling the water body to be in full contact with the microorganisms, and then realizing the purification of the water body by the decomposition of the microorganisms;

[0134] S5. Use the microorganism monitoring mechanism 30 to monitor the dynamic changes of the microorganism population in real time:

[0135] The quorum sensing signal molecules of bacteria can be accurately monitored through each dispersedly arranged quorum sensing signal sensor 32, and the monitoring results of multiple quorum sensing signal sensors 32 can compensate and correct each other to ensure the accuracy of the data; (The technology of the quorum sensing signal sensor 32 monitoring the quorum sensing signal molecules of bacteria is the existing well-known technology, and the technical means of the monitoring results of multiple quorum sensing signal sensors 32 being able to compensate and correct each other are also existing technical means, and will not be elaborated here)

[0136] S6. Compensate and add microorganism solution to the sewage:

[0137] According to the monitoring results of the quorum sensing signal sensor 32, determine the state of the microorganism population in the sewage. When the activity of the microorganism population decreases, continue to use the delivery pump to deliver the microorganism solution in the microorganism culture containment shell 41 to each dosing delivery pipe 401 in the water treatment loop channel 100. The microorganism solution in the dosing delivery pipe 401 is then discharged from the microorganism dosing nozzle 402, and further compensate and add the microorganism solution to the sewage, and continue to purify the sewage by the decomposition of the microorganisms to ensure that the purification efficiency of the microorganisms is at a relatively high level;

[0138] S7. Output of the purified sewage:

[0139] The purified sewage can then be uniformly discharged from the outlet pipe 102.

[0140] Embodiment 3:

[0141] On the basis of Embodiment 1, asFigure 1 As shown, a circulation driving mechanism 13 is provided in the sewage treatment loop channel 100. The circulation driving mechanism 13 includes a circulation driving plate 131 disposed in the sewage treatment loop channel 100 and arranged along the radial plane of the main body support housing 11;

[0142] A circulation driving support column 132 coaxial with the main body support inner shell 12 is fixed inside the main body support inner shell 12. The top of the circulation driving support column 132 is rotatably connected to a circulation driving support ring 133. A circulation driving support cross beam 134 extending radially along the circulation driving support column 132 is fixed to the outside of the circulation driving support ring 133. The top of the circulation driving plate 131 is fixedly connected to the circulation driving support cross beam 134;

[0143] As Figure 3 shown, a circulation driving telescopic rod 135 for driving the circulation driving support cross beam 134 to rotate around the axis of the circulation driving support ring 133 is fixed to the outside of the main body support housing 11. The circulation driving telescopic rod 135 is an electric control telescopic rod. The outer rod end of the circulation driving telescopic rod 135 is fixedly connected to the outer side wall of the main body support housing 11 through a circulation driving support seat 1350. The inner rod end of the circulation driving telescopic rod 135 is fixedly connected to one end of the circulation driving support cross beam 134 away from the circulation driving support ring 133;

[0144] As Figure 4 shown, the circulation driving plate 131 has a plurality of vertically extending circulation one-way flow grooves 130. A one-way flow blocking partition 136 is connected to the output side of the circulation driving plate 131 at the circulation one-way flow grooves 130. Blocking partition support seats 137 are fixed to both the upper and lower ends of the output side of the circulation driving plate 131 and located at the circulation one-way flow grooves 130. The blocking partition support seats 137 have vertically penetrating rotating shaft connection holes 1370. Vertically extending and coaxial blocking partition rotating shafts 138 are fixed to both the upper and lower ends of the one-way flow blocking partition 136. The blocking partition rotating shafts 138 are rotatably connected in the rotating shaft connection holes 1370;

[0145] A torsion spring is provided between the blocking partition rotating shaft 138 and the blocking partition support seat 137. One end of the torsion spring is fixedly connected to the blocking partition rotating shaft 138, and the other end of the torsion spring is fixedly connected to the blocking partition support seat 137. In the initial state, the torsion spring can drive the one-way flow blocking partition 136 to be hermetically fitted at the output side of the circulation one-way flow groove 130.

[0146] Example 4:

[0147] A method for enhancing sewage treatment based on quorum sensing, based on the device for enhancing sewage treatment based on quorum sensing in the above-mentioned Embodiment 3, different from Embodiment 2, in which in step S4, the circulation driving mechanism 13 is used to drive the water body in the sewage treatment loop channel 100 to flow continuously. All the one-way flow blocking partitions 136 are installed on the same side of the circulation driving plate 131, and the side with the one-way flow blocking partition 136 installed is the "backwater side", and the other side is the "water-facing side".

[0148] The rotation range of the circulation driving plate 131 around the circulation driving support ring 133 is 30°.

[0149] The process of the circulation driving plate 131 moving in the same direction as the water flow is the "driving stroke", and the process of the circulation driving plate 131 moving in the opposite direction to the water flow is the "reset stroke".

[0150] The inner rod of the circulation driving telescopic rod 135 extends and retracts to drive the circulation driving plate 131 to rotate reciprocally around the circulation driving support ring 133, so as to realize the "driving stroke" and the "reset stroke".

[0151] Taking the top view as an example, at this time, the clockwise direction is the driving direction of the water flow. The process of the circulation driving plate 131 rotating clockwise around the circulation driving support ring 133 is the "driving stroke", and the process of the circulation driving plate 131 rotating counterclockwise around the circulation driving support ring 133 is the "reset stroke".

[0152] During the "driving stroke" of the circulation driving plate 131, the circulation driving plate 131 moves in the same direction as the water flow, but the moving speed of the circulation driving plate 131 is greater than the water flow speed. Under the action of the water flow resistance, the "backwater side" of the circulation driving plate 131 makes each one-way flow blocking partition 136 closely contact the "backwater side" of the circulation driving plate 131, and the one-way flow blocking partition 136 seals the circulation one-way flow groove 130 at this time.

[0153] During the "reset stroke" of the circulation driving plate 131, the circulation driving plate 131 moves in the opposite direction to the water flow. Under the impact of the water flow, each one-way flow blocking partition 136 rotates around the axis of the rotating shaft connection hole 1370, so that the circulation one-way flow groove 130 is in a conducting state, enabling the circulating water flow to smoothly pass through each circulation one-way flow groove 130. The one-way flow blocking partition 136 acts as a one-way valve for the circulation one-way flow groove 130.

[0154] During the "driving stroke", the one-way flow blocking partition 136 seals the circulation one-way flow groove 130, enabling the entire circulation driving plate 131 to push the water body to flow in the clockwise direction. During the "reset stroke", the flowing water body can smoothly pass through each circulation one-way flow groove 130, reducing the deceleration effect of the circulation driving plate 131 on the water body.

[0155] Driven by the circulation drive telescopic rod 135, the circulation drive plate 131 continuously repeats the "driving stroke" and the "reset stroke", thereby continuously driving the water body in the sewage treatment loop channel 100 to flow in the clockwise direction.

[0156] Embodiment 5:

[0157] Based on Embodiment 3, as Figure 6 shown, a local temperature control mechanism 24 is provided at the input end of the sewage purification flow-through shell 22. As Figure 7 shown, the local temperature control mechanism 24 includes a local temperature control ring shell 241 fixed at the input end of the sewage purification flow-through shell 22. The inner side wall of the local temperature control ring shell 241 is a hollow structure. A temperature control input pipe 242 and a temperature control output pipe 243 are fixed on the outside of the local temperature control ring shell 241 and are connected to the inside of its side wall;

[0158] A plurality of hollow temperature control guide plates 244 are fixed on the inner side of the local temperature control ring shell 241, and the temperature control guide plates 244 are connected to the inside of the side wall of the local temperature control ring shell 241.

[0159] Embodiment 6:

[0160] A method for enhancing sewage treatment based on quorum sensing. Based on the device for enhancing sewage treatment based on quorum sensing in Embodiment 5 above, the difference from Embodiment 4 is that in step S4, the local temperature control mechanism 24 is used to finely adjust the temperature at the sewage purification flow-through shell 22, which is beneficial to keeping the microbial population attached to the microbial attachment plate 23 highly active at a suitable temperature;

[0161] Using a delivery pump of the prior art, warm water at 30°C is input into the inside of the local temperature control ring shell 241 through the temperature control input pipe 242. The warm water circulates inside the local temperature control ring shell 241 and inside each temperature control guide plate 244 and then is discharged from the temperature control output pipe 243. The water discharged from the temperature control output pipe 243 is guided through a pipeline to a separate water tank and heated. The warm water heated to 30°C is circulated into the inside of the local temperature control ring shell 241 by using a delivery pump;

[0162] Before the sewage flows into the inside of the sewage purification flow-through shell 22, it first contacts the local temperature control ring shell 241 and each temperature control guide plate 244 and undergoes heat exchange, which is beneficial to keeping the inside of the sewage purification flow-through shell 22 at a temperature suitable for microorganisms.

[0163] Embodiment 7:

[0164] Based on Embodiment 5, as Figure 8As shown in the figure, a sensor cleaning mechanism 33 is provided on the monitoring mechanism support column 31. The sensor cleaning mechanism 33 includes a cleaning support cylinder 331 fixed on the outside of the monitoring mechanism support column 31 and extending parallel to it. A cleaning moving cylinder 332 is slidably connected inside the cleaning support cylinder 331. A sensor cleaning ring 333 is fixed to the outer end of the cleaning moving cylinder 332. The sensor cleaning ring 333 is coaxially sleeved on the outside of the monitoring mechanism support column 31, and a cleaning brush 334 is provided inside the sensor cleaning ring 333.

[0165] A cleaning drive rod 335 for driving the cleaning moving cylinder 332 to move is provided inside the cleaning support cylinder 331. The cleaning drive rod 335 is an electrically controlled telescopic rod. The outer rod end of the cleaning drive rod 335 is fixedly connected to the cleaning support cylinder 331, and the inner rod end of the cleaning drive rod 335 is fixedly connected to the cleaning moving cylinder 332.

[0166] Example 8:

[0167] A method for treating sewage by quorum sensing enhancement. Based on the device for treating sewage by quorum sensing enhancement in the above Example 7, the difference from Example 6 is that in step S5, during the operation of each quorum sensing signal sensor 32, microorganisms will continuously attach to its surface, and suspended pollutants in the water body will also continuously attach to the surface of the quorum sensing signal sensor 32. The sensor cleaning mechanism 33 is used to clean each quorum sensing signal sensor 32 to ensure the accuracy of the quorum sensing signal sensor 32.

[0168] The extension and retraction of the inner rod of the cleaning drive rod 335 drive the cleaning moving cylinder 332 to reciprocate along the axis of the cleaning support cylinder 331. The cleaning moving cylinder 332 drives the sensor cleaning ring 333 to reciprocate together. The cleaning brush 334 inside the sensor cleaning ring 333 is used to remove the microorganisms and pollutants attached to the surface of the quorum sensing signal sensor 32, realizing the cleaning effect on the quorum sensing signal sensor 32.

[0169] Test example:

[0170] Taking sewage with organic pollution as an example, the COD is about 500 mg / L. The technical solutions of Example 2, Example 4, Example 6, and Example 8 are respectively used for sewage treatment, and the water quality is detected after 48 hours of treatment.

[0171] And a comparative example is set. Similarly, for sewage with organic pollution, the COD is about 500 mg / L. Under the same conditions, the physical and biological treatment process of the existing technology is used for purification treatment, and the water quality is detected after 48 hours of treatment. The detection results are as follows:

[0174] Through the above comparative analysis, it can be seen that the device for treating sewage by quorum sensing enhancement based on the present invention is used to treat organic polluted sewage, and there is a significant improvement in the treatment effect, showing excellent treatment efficiency and removal rate of organic pollution. Moreover, with the use of the circulation driving mechanism 13, the local temperature control mechanism 24 and the sensor cleaning mechanism 33, the sewage treatment effect can be further improved. Compared with the biological treatment process of the prior art, the treatment effect of the present invention on organic polluted sewage has generally increased by about 10%.
