Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a wastewater monitoring device. Background Technology

[0002] Microbial electrochemical technology is increasingly widely used in wastewater treatment. Its unique advantage lies in its ability to convert organic matter in wastewater into electrical or hydrogen energy, while simultaneously achieving efficient degradation of pollutants. With the in-depth research and continuous improvement of this technology, microbial sensors have emerged as a novel monitoring tool. These sensors form biofilms by immobilizing specific functional microorganisms on electrode surfaces, utilizing changes in electrical signals generated during microbial metabolism to reflect the wastewater quality and microbial activity in real time. A stronger signal indicates increased organic matter concentration and active microbial metabolism; a weaker signal reflects decreased organic matter or the presence of toxic inhibition.

[0003] For example, patent CN222580004U discloses a microbial sensor used in online water quality monitoring instruments. It uses a spherical anode and an air cathode within a reaction chamber. Electroactive microorganisms adhere to the spherical anode, forming a biofilm, which is decomposed by applying voltage. This eliminates the need for expensive cathode catalysts, resulting in lower costs. However, when used for wastewater toxicity monitoring, this microbial sensor is susceptible to long-term inhibition by toxic wastewater, easily leading to microbial death and rendering the sensor ineffective.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0033] like Figures 1 to 6 As shown, this utility model provides a wastewater monitoring device, which includes a monitoring base 1 and a monitoring mechanism 3. The monitoring base 1 has a working chamber 11, which is divided into a monitoring chamber 111 and a resuscitation chamber 112 by a partition 12. The monitoring base 1 has a first opening 13 communicating with the monitoring chamber 111 and a second opening 14 communicating with the resuscitation chamber 112. The resuscitation chamber 112 is provided with a resuscitation mechanism 2. The monitoring mechanism 3 includes a driving component 31 disposed on the monitoring base 1. The driving end of the driving component 31 is provided with a monitoring component 32. The monitoring component 32 includes a microbial sensor 321 and a microbial monitoring probe 322. The driving end of the driving component 31 can be located in the monitoring chamber 111 through the first opening 13 and in the resuscitation chamber 112 through the second opening 14.

[0034] The partition 12 divides the working chamber 11 into a monitoring chamber 111 and a resuscitation chamber 112, allowing them to operate independently without interference. This provides space for microbial monitoring and resuscitation, avoiding potential cross-influence from monitoring and resuscitation operations in a single space, thus improving monitoring accuracy and resuscitation effectiveness. The monitoring seat 1 can be placed under the sewage, or the monitoring chamber 111 of the monitoring seat 1 can be located under the sewage, with the driving component 31 driving the monitoring component 32 to be positioned within the monitoring chamber for sewage monitoring. In harsh conditions such as when the sewage is toxic wastewater, the microbial sensor 321 is prone to microbial death due to prolonged exposure to the inhibitory impact of toxic wastewater, rendering it unable to monitor properly. By driving the monitoring component 32 to be positioned within the resuscitation chamber 112 via the driving component 31, the resuscitation mechanism 2 activates and resuscitates the microorganisms, allowing them to be reused. This solves the problem of traditional microbial sensors 321 failing to detect toxicity over long-term monitoring due to the easy death of microorganisms.

[0035] The monitoring component 32 includes a microbial sensor 321 and a microbial monitoring probe 322. The microbial monitoring probe 322 is used to detect the activity and quantity changes of microorganisms in wastewater in real time. By inserting the microbial monitoring probe 322 into the wastewater, it captures the metabolic signals, bioelectrical activity, or other relevant biochemical indicators of the microorganisms, reflecting important information such as the type, activity, quantity, and growth status of the microorganisms in the microbial sensor 321, thereby determining whether the microorganisms need to be reactivated and revived. The microbial sensor 321 utilizes the specific response of microorganisms to specific chemical substances or environmental conditions, converting this response into a measurable signal, thereby achieving accurate detection of wastewater.

[0036] In some embodiments, a working cavity 11 is formed within the monitoring seat 1. The working cavity 11 is divided into a monitoring chamber 111 and a resuscitation chamber 112 by a partition 12. The monitoring seat 1 has a first opening 13 communicating with the monitoring chamber 111 and a second opening 14 communicating with the resuscitation chamber 112. The partition 12 can be placed horizontally, thereby dividing the working cavity 11 vertically into the monitoring chamber 111 and the resuscitation chamber 112; or the partition 12 can be placed vertically, dividing the working cavity 11 horizontally into the monitoring chamber 111 and the resuscitation chamber 112; or the partition 12 can be tilted, dividing the working cavity 11 into the monitoring chamber and the resuscitation chamber 112 on both sides of the tilt direction. In this embodiment, the partition 12 is placed vertically, dividing the working cavity 11 horizontally into the monitoring chamber 111 and the resuscitation chamber 112. The monitoring chamber 111 and the resuscitation chamber 112 are arranged side by side, and both the first opening 13 and the second opening 14 are located at the top of the monitoring seat 1. Correspondingly, the drive component 31 is located above the monitoring base 1. This reduces the likelihood of the drive component 31 being submerged in sewage when the monitoring base 1 is placed in the sewage for detection, thus ensuring the reliability of the drive component 31's operation. Of course, if the drive component 31 needs to be submerged in sewage, a protective component can be provided on its outer periphery. This protective component separates the drive component 31 from the sewage, providing waterproof protection and extending its service life.

[0037] The drive end of the drive component 31 can be located in the monitoring chamber 111 through the first opening 13 and in the resuscitation chamber 112 through the second opening 14. The drive end of the drive component 31 can be rotated or moved horizontally in at least two directions, thereby ensuring that the drive end of the drive component 31 can drive the monitoring component 32 to reciprocate stably in the monitoring chamber 111 and the resuscitation chamber 112.

[0038] In this embodiment, the driving component 31 includes a rotator 312, with a rotating rod connected to the rotator 312 as the driving end. The rotating shaft of the rotator 312 is connected to the rotating rod, thus driving the rotation of the rotating rod. The first opening 13 and the second opening 14 are both on the rotation path of the rotating rod. Therefore, the driving component 31 can drive the monitoring component 32 to stably switch between the monitoring chamber 111 and the resuscitation chamber 112, realizing monitoring and resuscitation. The rotator 312 may include a rotating motor or a rotating cylinder, etc.

[0039] In some embodiments, the monitoring chamber 111 is divided into a first monitoring area 1111 and a second monitoring area 1112 located below the first monitoring area 1111. A flow hole 15 is provided through the monitoring seat 1 at the corresponding location of the second monitoring area 1112. The flow hole 15 allows wastewater to form a good flow circulation within the monitoring chamber 111, avoiding local stagnation or uneven distribution of wastewater within the chamber. This ensures that the microbial sensor 321 and the microbial monitoring probe 322 can contact a more uniform wastewater sample, thereby improving the reliability of the monitoring data.

[0040] Furthermore, the drive end of the drive component 31 is provided with a telescopic component 311, and the monitoring component 32 is disposed at the telescopic end of the telescopic component 311. The telescopic component 311 allows the monitoring component 32 to adjust its insertion depth as needed when entering the monitoring chamber 111 or the resuscitation chamber 112. Inside the monitoring chamber 111, the monitoring component 32 can be inserted into a suitable wastewater layer according to the depth of the wastewater and monitoring requirements, ensuring the accuracy of the monitoring data. Inside the resuscitation chamber 112, the position of the monitoring component 32 can be flexibly adjusted according to the layout and operational requirements of the resuscitation mechanism 2, providing optimal conditions for the resuscitation of microorganisms and further enhancing the flexibility and applicability of the device. The telescopic component 311 may include an electric push rod or a cylinder, etc.

[0041] In some embodiments, a center of gravity stabilizer 4 is provided at the bottom of the monitoring base 1. Since the wastewater monitoring device is usually used on the water surface, the center of gravity stabilizer 4 can effectively lower the center of gravity of the device, enhance its stability during operation, prevent the device from tipping over or shaking due to external interference or its own operation, thereby ensuring the stability of monitoring and recovery operations and extending the service life of the device.

[0042] In some embodiments, the wastewater monitoring device further includes a base 5, with the monitoring base 1 disposed at the bottom of the base 5. A receiving cavity 511 is formed within the base 5, and a water supply component 21 and an oxygen supply component 22 are disposed within the receiving cavity 511. The outlet end of the water supply component 21 is located within the recovery chamber 112, and the oxygen outlet end of the oxygen supply component 22 is connected to an aeration component 23, which is located within the recovery chamber 112. A drain outlet 16 is provided on the recovery chamber 112. The water supply component 21 provides water to the recovery chamber 112, and the oxygen supply component 22, in conjunction with the aeration component 23, provides sufficient oxygen for the recovery of microorganisms, promoting their metabolism and growth, accelerating the recovery process, and improving recovery efficiency.

[0043] Optionally, the drain outlet 16 is located at the bottom of the resuscitation chamber 112, thereby ensuring drainage efficiency and effectiveness.

[0044] The oxygen delivery component 22 includes an oxygenation component 221 and an oxygen delivery pipe 222. The input end of the oxygen delivery pipe 222 is connected to the oxygenation component 221, and the output end of the oxygen delivery pipe 222 is located inside the resuscitation chamber 112 and is used to connect with the aeration component 23 to achieve aeration.

[0045] Optionally, a first level gauge 17 is installed inside the resuscitation chamber 112, and a control mechanism 6 is installed inside the accommodating cavity 511. The control mechanism 6 is electrically connected to the first level gauge 17 and is also controlled to connect to the water supply component 21. The first level gauge 17 can monitor the liquid level inside the resuscitation chamber 112 in real time. When the first level gauge 17 senses a low liquid level, the control mechanism 6 automatically controls the water supply component 21 to replenish water to the resuscitation chamber 112, achieving automated control and improving efficiency.

[0046] The water supply component 21 includes a water supply interface 211 mounted on the base 5. The water supply interface 211 is used to connect to external water resources. The water supply connector is connected to the inlet end of the water supply pipe 213 via a first switch 212. The outlet end of the water supply pipe 213 is connected to the resuscitation chamber 112. The control mechanism 6 is connected to the first switch 212. When the first level gauge 17 in the resuscitation chamber 112 senses a low level, the control mechanism 6 controls the first switch 212 to open, and the water supply interface 211 supplies water to the resuscitation chamber 112 through the water supply pipe 213. The first switch 212 may include a solenoid valve, an electric valve, or a pneumatic valve, etc.

[0047] In some embodiments, the accommodating cavity 511 is further provided with a nutrient solution addition chamber 7. The outlet end of the nutrient solution addition chamber 7 is connected to the resuscitation chamber 112. The nutrient solution addition chamber 7 is used to provide the necessary nutrients for the resuscitation of microorganisms, ensuring that the microorganisms can obtain sufficient energy and components required for growth during the resuscitation process. One, two, three, or more nutrient solution addition chambers 7 may be provided, depending on the type and quantity of nutrient solution required, thus different numbers of nutrient solution addition chambers 7 may be provided in the accommodating cavity 511.

[0048] Optionally, a second level gauge 8 is installed in the nutrient solution addition tank 7, and the control mechanism 6 is connected to the second level gauge 8 and the inlet end of the nutrient solution addition tank 7. The second level gauge 8 is used to monitor the remaining nutrient solution in the nutrient solution addition tank 7. When the second level gauge 8 senses a low level, it transmits a signal to the control mechanism 6, which will automatically sound an alarm to remind staff to replenish the nutrient solution in time. This avoids poor microbial resuscitation due to insufficient nutrient solution, further improving the reliability and operating efficiency of the device.

[0049] The seat 5 is equipped with an infusion interface 513, which is used to connect to external nutrient solution. The infusion interface 513 is connected to the nutrient solution addition chamber 7 to replenish the nutrient solution in the nutrient solution addition chamber 7.

[0050] Optionally, the outlet end of the nutrient solution addition chamber 7 is connected to a dosing pipe 9, and the other end of the dosing pipe 9 is connected to the resuscitation chamber 112. A second switch 10 is installed on the dosing pipe 9, and the control mechanism 6 is connected to the second switch 10. After the monitoring component 32 is located inside the resuscitation chamber 112, the control mechanism 6 controls the second switch 10 to open, and the nutrient solution addition chamber 7 inputs nutrient solution into the resuscitation chamber 112 through the dosing pipe 9. The second switch 10 includes a solenoid valve, an electric valve, or a pneumatic valve, etc.

[0051] In some embodiments, the base 5 includes a main base 51 and an annular base 52. A receiving cavity 511 is formed within the main base 51, and a handle 512 is provided at the top of the main base 51. The annular base 52 is located below the main base 51, and an annular cavity 521 is formed within the annular base 52. A through hole 522 is formed in the center of the annular base 52, and a monitoring seat 1 is disposed within the through hole 522. The top of the monitoring seat 1 is connected to either the main base 51 or the annular base 52. The receiving cavity 511 formed inside the main base 51 provides placement space. With the annular cavity 521 of the annular base 52, after the device is placed on the water surface, the annular base 52 can act as a stable floating island, further enhancing the stability of the device. Simultaneously, it provides additional support and protection to the receiving cavity 511 within the main base 51, making the entire device more stable and reliable, and better able to adapt to complex working environments.

[0052] In summary, this application provides a wastewater monitoring device. The bottom of the ring seat 52 is the wastewater surface. When the rotator 312 rotates the microbial monitoring probe 322 to the monitoring chamber 111, the telescopic component 311 automatically extends, inserting the microbial monitoring probe 322 below the wastewater surface for monitoring. After the microbial monitoring probe 322 has monitored for a certain period of time, or after the microbial resuscitation time interval is set by the control mechanism 6, the telescopic component 311 automatically retracts, and then rotates to rotate the microbial sensor 321 to the resuscitation chamber 112. The water inlet 211 is connected to a water source. When the first level gauge 17 in the resuscitation chamber 112 senses a low level, the control mechanism 6 opens the first switch 212 to replenish the water source. The oxygen supply component 22 and the aeration component 23 are turned on, and the second switch 10 is turned on, allowing the nutrient solution addition chamber 7 to add nutrients to the resuscitation chamber 112. When the second level gauge 8 senses a low level, the control mechanism 6 will automatically alarm, indicating that materials need to be added to the nutrient solution addition chamber 7. After the microorganisms attached to the microbial sensor 321 have recovered, the rotor 312 drives the microbial monitoring probe 322 to rotate into the monitoring chamber 111 to continue monitoring. In this way, the microbial sensor 321 can activate and recover microorganisms when used in harsh environments such as wastewater toxicity monitoring, enabling the device to be reused. This solves the problem of traditional microbial sensors 321 failing to monitor wastewater toxicity over long periods due to the death of microorganisms.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
