Description

Technical Field

[0001] The present invention relates to the technical field of anaerobic toxicity experiments, and particularly to an integrated anaerobic toxicity experiment system for industrial wastewater. Background Art

[0002] Industrial wastewater generally has the characteristics of large volume, strong toxicity, high concentration and great treatment difficulty. As one of the key technologies in sewage treatment plants, anaerobic biological treatment has been widely used in the degradation of industrial wastewater. However, anaerobic microorganisms are easily impacted by high-concentration toxic substances in the wastewater, resulting in unstable treatment effects and even system paralysis. Therefore, how to accurately evaluate the toxicity of wastewater before it enters the sewage treatment plant has become the key to solving this problem.

[0003] Current anaerobic toxicity detection methods mainly rely on indirectly evaluating the toxicity of wastewater through the methane production rate. This method infers the wastewater toxicity by measuring the rate at which microorganisms decompose organic matter to produce methane in an anaerobic environment. However, this method is cumbersome to operate, requires continuous manual data recording, and is affected by environmental factors (such as temperature, air pressure, etc.), so the accuracy and stability of experimental results are often poor. In addition, since the methane production rate method takes a long time to obtain results, during the experiment, multiple experimenters need to shake the reaction bottles and read gas data for a long time, which greatly wastes human resources. At the same time, the experimental equipment needs to be assembled before the experiment and cleaned and stored after the experiment. The scattered experimental tools make the operation extremely inconvenient. Currently, there is no integrated automated experimental system for detecting the anaerobic toxicity of wastewater on the market.

[0004] To solve these problems, this research developed an integrated anaerobic toxicity experiment system for industrial wastewater. This system can quickly and accurately evaluate the anaerobic biological toxicity of wastewater before it enters the sewage treatment plant, thereby providing a scientific basis for decision-making on whether the wastewater can enter the treatment plant. Through an automated integrated design, this system significantly improves the detection efficiency, reduces manual intervention, ensures the accuracy and stability of the results, and provides a new wastewater toxicity evaluation tool for sewage treatment plants. Summary of the Invention

[0012] By setting the measurement return component, during the unmanned experiment, when the gas fills the gas collection system, the measurement return component can automatically control the gas discharge after recording, so that no operator assistance is required during the long-term experiment.

[0013] Further, the measurement return component includes an electric push rod, a laser rangefinder, and a target plate. The rear end of the electric push rod is inserted into the upper plate, and the output end of the electric push rod extends downward through the upper plate. The side of the laser rangefinder is inserted into the side of the connecting rod away from the piston head. The side of the target plate is clamped to the upper side of the piston chamber. A one-way electromagnetic exhaust is provided on the lower end of the piston chamber away from the air outlet pipe.

Detailed implementation mode

[0029] To make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention will be described in detail below in conjunction with the drawings as follows:

[0030] As Figures 1 to 8 shown, the present application proposes an integrated industrial wastewater anaerobic toxicity experiment system, including an integrated device 1, a feeding system 2 and a gas collection system 3; the feeding system 2 is arranged on the side of the integrated device 1, the gas collection system 3 is clamped with the integrated device 1, and a conical flask 4, a bottle shaking mechanism 5 and a controller for controlling the feeding system 2, the gas collection system 3 and the bottle shaking mechanism 5 are arranged in the integrated device 1;

[0031] The feeding system 2 and the gas collection system 3 are respectively communicated with the conical flask 4. The feeding mechanism automatically pumps the reactants into the conical flask 4 in proportion for reaction. The gas generated by the reaction in the conical flask 4 enters the gas collection system 3 for automatic reading and recording. The bottle shaking mechanism 5 drives the conical flask 4 to perform a shaking operation before the gas collection system 3 reads the data.

[0032] See Figure 1 and Figure 2, the integrated device 1 includes a single host 11 and an array of modular machines 12; both the host 11 and the modular machines 12 include a base 13, a water bath tank 14, a support plate 15, a sliding plate 16, and an upper plate 17. The water bath tank 14 is inserted into the upper end of the base, the lower end of the support plate 15 is fixedly welded to the base 13, the upper end of the support plate 15 is fixedly welded to the upper plate 17, and the side of the sliding plate 16 is slidably connected to the inner wall of the base 13 with damping. A heating device is provided on the periphery of the water bath tank 14. When the water bath tank 14 is inserted into the base, it is electrically connected to the controller, so that the heating mode of the water bath tank 14 can be directly controlled.

[0033] See Figure 3 , a control panel 111 is provided at the front of the host 11. The host 11 and the modular machines 12 are inserted into each other. Each electrical control device can be directly controlled through the control panel 111, and the gas reading and the time for taking the gas reading can be recorded through the control panel 111. When the host 11 and the modular machines 12 are inserted into each other, the modular machines 12 are connected to the host 11 and are synchronously controlled through the control panel 111.

[0034] See Figure 7 , in order to achieve different numbers of parallel groups and control groups required for various experiments, an insertion plate 131 is provided at the front section of the base 13, a slot 132 is provided at the rear end of the base 13, an electrical control board is provided inside the base 13, and the array of modular machines 12 are inserted into each other and are electrically connected. This design enables free rotation and deployment of different groups for mutual insertion, and finally all are connected to the host 11, so that the experimental system can be assembled modularly to meet different experimental requirements.

[0035] A support 133 is provided at the lower part of the base 13 of the host 11 so that the device is placed on the experimental table. The lower part of the support 133 is made of a material with high friction to prevent the device from sliding and deflecting. A universal wheel 134 is provided at the lower part of the base 13 of the modular machine 12 to facilitate the mutual insertion of the modular machines 12 to form a complete experimental system. The insertion between the insertion plate 131 and the slot 132 is a lockable and unlockable connection, making the connection between them more stable.

[0036] As another embodiment, as Figure 2As shown in the figure, the feeding system 2 includes an array of jigs 21, a gas cylinder 22, a liquid bottle 23, a sludge bottle 24, a fluid pump 25, a gas pump 26, a feeding pipe 27, and a two-way three-way solenoid valve 28; the rear end of the jig 21 is fixedly connected to the outer side of the support plate 15, and the rear ends of the fluid pump 25, the gas pump 26, and the two-way three-way solenoid valve 28 are all inserted into the outer side of the support plate 15. The gas cylinder 22, the liquid bottle 23, and the sludge bottle 24 are all clamped to the jig 21. The gas cylinder 22 is connected to the gas pump 26 through the feeding pipe 27. The sludge bottle 24 is connected to the liquid bottle 23 through the feeding pipe 27 and extends to be connected to the fluid pump 25. The fluid pump 25 is connected to the gas pump 26 through the two-way three-way solenoid valve 28. The two-way three-way solenoid valve 28 is connected to the side of the conical flask 4 through the feeding pipe 27. A one-way valve is provided at the feeding port of the conical flask 4.

[0037] Among them, the liquid bottle 23 and the sludge bottle 24 can be directly connected to the material storage device, or the nutrient solution and sludge can be filled in advance for temporary storage of the material. The gas cylinder 22 is directly connected to the gas storage device. The jig 21 can be a wrapped arc-shaped jig 21 as shown in Figure 2 . By setting a clamping member with a certain deformation ability, the material bottle body can be directly clamped in, so that it can be removed for cleaning after the experiment is completed.

[0038] Furthermore, the sludge bottle 24 can also be directly connected to the anaerobic aeration tank through a pipeline. By storing the sludge for the experiment in the anaerobic aeration tank, an anaerobic environment is provided for the sludge, so that the sludge remains in a stable state. The gas used for anaerobic aeration can be selected from nitrogen or carbon dioxide gas.

[0039] After the material preparation before the experiment is completed, the gas collection system 3 is not connected to the conical flask 4 for the time being. The gas pump 26 is started first, and nitrogen is pumped into the two-way three-way solenoid valve 28 through the gas cylinder 22 and finally pumped into the conical flask 4 to discharge the air in the conical flask 4. Then the water bath 14 is started to heat the internal conical flask 4. The two-way three-way solenoid valve 28 is switched, and then the fluid pump 25 is started to suck the sludge and the nutrient solution at the same time. The sludge and the nutrient solution are preliminarily mixed in the feeding pipe 27 and finally pumped into the conical flask 4 to start the reaction. At this time, the gas collection system 3 is connected to the conical flask 4.

[0040] It should be noted that a one-way valve is provided at the feeding port of the conical flask 4 to prevent the backflow of gas and materials. The upper end of the conical flask 4 is a sealable design, and its feeding port and air outlet are both provided on the upper sides on both sides; after the experiment is completed, the conical flask 4 can be taken out separately for cleaning.

[0041] As another embodiment, as shown in Figure 3 and Figure 4As shown, the gas collection system 3 includes an air outlet pipe 31, a piston chamber 32, a piston head 33, a connecting rod 34, and a measurement and return component 35; one end of the air outlet pipe 31 is connected to the side of the conical flask 4 with a one-way valve, and the other end of the air outlet pipe 31 is connected to the side of the lower part of the piston chamber 32 with a one-way valve. The lower end of the piston chamber 32 is inserted into the upper end of the sliding plate 16. The piston head 33 is slidably connected to the inside of the piston chamber 32. One end of the connecting rod 34 is fixedly connected to the rear end of the piston head 33, and the other end of the connecting rod 34 is inserted into the measurement and return component 35.

[0042] Among them, by pulling out the set sliding plate 16, the installation and disassembly of the gas collection system 3 can be quickly carried out. After the feeding operation is completed, manually connect the air outlet pipe 31 on the side of the piston chamber 32 to the conical flask 4. When a reaction occurs in the conical flask 4, methane gas enters the inside of the piston chamber 32 through the air outlet pipe 31, pushing up the piston head 33. The piston head 33 then undergoes a vertical displacement, driving the connecting rod 34 to displace synchronously. Through the preset recording interval, the measurement and return component 35 can automatically record the displacement distance of the connecting rod 34, and then read and record the gas volume.

[0043] See Figure 3 , the measurement and return component 35 includes an electric push rod 351, a laser rangefinder 352, and a target plate 353. The rear end of the electric push rod 351 is inserted into the upper plate 17, and the output end of the electric push rod 351 extends downward through the upper plate 17. The side of the laser rangefinder 352 is inserted into the side of the connecting rod 34 away from the piston head 33. The side of the target plate 353 is clamped to the side of the upper end of the piston chamber 32. A one-way electromagnetic exhaust 321 is provided on the side of the lower end of the piston chamber 32 away from the air outlet pipe 31. The piston chamber 32 is connected to the methane treatment mechanism through the one-way electromagnetic exhaust 321.

[0044] When the connecting rod 34 is driven upward by the gas, it drives the laser rangefinder 352 to move away from the target plate 353 synchronously. When reading is required, the laser rangefinder 352 is activated to emit laser to the target plate 353 for ranging and automatically record and convert through the control panel 111;

[0045] It should be noted that the laser rangefinder 352 can be replaced by other ranging tools made of other materials in other existing technologies that can achieve the above technical effects, such as infrared rangefinders and other commonly used rangefinders with high precision. At the same time, when the connecting rod 34 displaces to the output end of the electric push rod 351, the laser rangefinder 352 is automatically activated to measure the reading and record the time. Subsequently, the electric push rod 351 is automatically activated to press the connecting rod 34 downward to displace. The electromagnetic one-way valve in the piston chamber 32 is activated. As the connecting rod 34 moves downward, it pushes the piston head 33 downward, and then discharges the methane gas from the piston chamber 32 into the methane treatment mechanism for treatment.

[0046] Further, as an alternative solution, the gas collection system 3 can also be designed using the traditional water drainage method. By replacing the piston chamber 32 with a water body bottle connected to the conical flask 4 and arranging an additional drainage bottle connected to the water body bottle on the sliding plate 16, and setting a liquid level detector in the drainage bottle, when the gas enters the water body bottle, the water body will be discharged into the drainage bottle, and then the volume of the gas can be measured by reading the water body in the drainage bottle.

[0047] Further, as an alternative solution, the gas collection system 3 can be designed by replacing the piston chamber 32 with a storage bottle. The storage bottle is connected to the conical flask 4 through a gas flowmeter. At the same time, an infrared sensor is used to detect the concentration of methane gas in the storage bottle, and finally the volume of the gas is calculated through formula calculation of the data by the control panel 111.

[0048] As another embodiment, as Figures 5 to 8 shown, the bottle shaking mechanism 5 includes a clamping plate 51, a ball joint 52, a joint sleeve 53, a worm gear 54, a telescopic outer rod 55, a telescopic inner rod 56, an arc-shaped connecting plate 57, and a modular driving component 58; the lower end of the clamping plate 51 is clamped with the upper end of the conical flask 4, the upper end of the clamping plate 51 is welded and fixed to the lower end of the ball joint 52, the ball joint 52 is movably connected to the inner wall of the joint sleeve 53, the upper end of the joint sleeve 53 is fixedly connected to the lower end of the telescopic outer rod 55, the inner wall of the telescopic outer rod 55 and the outer wall of the telescopic inner rod 56 are connected with limited sliding, the upper end of the telescopic inner rod 56 is fixedly connected to the lower end of the upper plate 17, the inner wall of the worm gear 54 is threadedly connected to the outer wall of the telescopic outer rod 55, the upper end of the arc-shaped connecting plate 57 is inserted into the lower end of the upper plate 17, and the lower end of the arc-shaped connecting plate 57 is rotatably connected to the upper end of the worm gear 54.

[0049] Before the experiment, the upper end of the conical flask 4 is clamped with the lower end of the clamping plate 51, and the conical flask 4 is placed in the water bath box 14 for heating;

[0050] When reading is required, the modular driving component 58 is started to drive the worm gear 54 to rotate. Due to the threaded connection between the worm gear 54 and the telescopic outer rod 55 and the limitation of the worm gear 54 by the arc-shaped connecting plate 57, the worm gear 54 will not have a vertical displacement during rotation. The telescopic outer rod 55 is driven by the threaded connection of the worm 582 to move upward along the telescopic inner rod 56. At the same time, the telescopic inner rod 56 limits the telescopic outer rod 55 to prevent the telescopic outer rod 55 from rotating. The vertical movement of the telescopic outer rod 55 drives the joint sleeve 53 and the ball joint 52 to move upward, and then drives the clamping plate 51 and the conical flask 4 to move upward, so that the conical flask 4 is separated from the water bath box 14 to prevent subsequent shaking from occurring in the water bath box 14.

[0051] See Figure 5 、 Figure 6 and Figure 8, a threaded section 551 is provided on the outer wall of the telescopic outer rod 55. The lower part of the threaded section 551 is a flat threaded section 552. A push rod 541 is clamped at the lower end of the worm gear 54. A ball 542 is movably arranged at one end of the push rod 541 away from the worm gear 54. An electromagnetic trigger 171 for triggering gas reading is provided at the lower end of the upper plate 17.

[0052] In the normal state, the internal thread of the worm gear 54 is threadedly connected to the threaded section 551 of the telescopic outer rod 55. As the worm gear 54 rotates, the telescopic outer rod 55 gradually moves upward. When the upper end of the telescopic outer rod 55 contacts the lower end of the upper plate 17, the flat threaded section 552 of the telescopic outer rod 55 contacts the internal thread of the worm gear 54, making the rotation of the worm gear 54 unable to continue driving the telescopic outer rod 55 upward. As the telescopic outer rod 55 rises, the clamping plate 51 rises accordingly and contacts the ball 542. Driven by the ball 542 and the push rod 541, the clamping plate 51 deflects, driving the conical flask 4 to deflect;

[0053] The continuous rotation of the worm gear 54 drives the push rod 541 and the ball 542 to continuously perform circular motion, causing the clamping plate 51 to drive the conical flask 4 to produce a shaking effect. The friction of the ball 542 is small, and it basically does not drive the clamping plate 51 to rotate itself. At the same time, the feed pipe 27 and the air outlet pipe 31 exert a certain pulling effect on the conical flask 4, offsetting the driving effect generated by the tiny friction in the contact between the ball 542 and the clamping plate 51, thereby preventing the clamping plate 51 and the conical flask 4 from rotating themselves.

[0054] At the same time, when the upper end of the telescopic outer rod 55 contacts the upper plate 17, the electromagnetic trigger 171 is contacted. After the shaking operation is completed, the modular driving component 58 drives the worm gear 54 to reverse, and the telescopic outer rod 55 moves vertically downward, disengaging from the electromagnetic trigger 171. At this time, the gas collection system 3 is automatically triggered to perform the gas reading and recording operation. As the clamping plate 51 and the conical flask 4 descend, the push rod 541 disengages from the clamping plate 51. Affected by gravity, the conical flask 4 returns to the vertical state and enters the water bath tank 14 to continue the reaction.

[0055] See Figure 5 and Figure 6 , the modular driving component 58 includes a motor 581 and a worm 582. The motor 581 is bolted to the support plate 15 of the main machine 11. The output end of the motor 581 is inserted into the worm 582. The worm 582 is rotatably connected to the support plate 15. The array of worms 582 are inserted into each other, and the worm 582 meshes with the worm gear 54.

[0056] Among them, the motor 581 is a forward and reverse motor 581. The form in which the worms 582 are inserted into each other enables the module 12 to be driven by the motor 581 to rotate synchronously after being connected to the main machine 11. Thus, the main machine 11 and the module 12 perform the shaking operation of the conical flask 4 at the same time, thereby unifying the reading time and the shaking effect.

[0057] Working principle:

[0058] Before the experiment, set the required parallel groups and control groups. Connect the conical flask 4 to the card board 51 and place it in the water bath 14. Then connect the feeding system 2 to the material storage mechanism. After inserting each module machine 12 into the main machine 11 and plugging them into each other in sequence, the experiment can start. First, pump nitrogen into the conical flask 4 through the gas pump 26 to empty the air. Then connect the gas collection system 3 to the conical flask 4, and the experiment can start automatically. Pump the sludge and nutrient solution mixture into the conical flask 4 through the fluid pump 25 for water bath heating reaction. The gas generated by the reaction enters the gas collection system 3 for storage;

[0059] Before reaching the set reading time, the motor 581 starts to drive the worm 582 to rotate. The mutually plugged worms 582 rotate synchronously, thereby driving the worm gear 54 to rotate. Then the telescopic outer rod 55 gradually moves upward. The card board 51 rises accordingly and contacts the ball 542, driving the card board 51 to drive the conical flask 4 to deflect. The continuous rotation of the worm gear 54 drives the push rod 541 and the ball 542 to continuously perform circular motion, driving the conical flask 4 to produce a shaking effect. After the shaking is completed, the worm gear 54 rotates in reverse, and the telescopic outer rod 55 moves vertically downward, disengaging from the electromagnetic trigger 171. The gas collection system 3 performs the gas reading and recording operation.
