Description

Technical Field

[0001] The present invention relates to the field of wastewater treatment technology, and in particular to a method and equipment for enhancing micro-electrolysis wastewater treatment by magnetic field synergistic regulation. Background Technology

[0002] Iron-carbon micro-electrolysis technology is a wastewater treatment technology based on electrochemical oxidation-reduction reactions. It utilizes the potential difference between iron and carbon to form micro-batteries, degrading pollutants such as organic matter and heavy metals through electron transfer, adsorption, and co-precipitation. It is widely used in industrial wastewater treatment in dyeing, pharmaceuticals, and electroplating, reducing wastewater color and chemical oxygen demand, improving biodegradability, and adsorbing and reducing heavy metal ions. Current practical applications include pretreatment, micro-electrolysis reaction, solid-liquid separation, and subsequent treatment. The influent hydrogen ion concentration index needs to be adjusted to approximately 3 before being pumped into the reaction tower. The wastewater treated by micro-electrolysis is discharged through the effluent outlet to enter the next treatment structure. However, this technology has significant bottlenecks: during long-term operation, oxides such as Fe(OH)3 and Fe2O3 generated by the electrode reaction form passivation films on the surface of the packing material and inside the reactor, leading to packing caking, severely reducing treatment efficiency, and even preventing electrolysis from taking place; traditional systems rely on manual sampling and testing at regular intervals and manual adjustment of parameters such as hydrogen ion concentration index, aeration rate, and reaction time, resulting in slow response, low accuracy, and high labor costs; although a weak magnetic field can enhance the removal of pollutants by zero-valent iron, and a weak magnetic field can be formed by arranging a magnetic levitation base or magnet at the bottom of the reactor, the magnetic field is only generated at the bottom, with a limited range of effect, failing to fully utilize the magnetic field enhancement effect. To address these shortcomings, there is an urgent need for a micro-electrolysis wastewater treatment method that can effectively inhibit packing caking, achieve intelligent control, and fully utilize the magnetic field enhancement effect, in order to improve treatment efficiency, reduce operating costs, and enhance the system's automation level.

The execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0025] This invention provides a magnetic field-coordinated enhanced micro-electrolysis wastewater treatment method, see [link to relevant documentation]. Figure 1The method includes: Step S1: Adjusting the hydrogen ion concentration index of wastewater to obtain regulated wastewater, and pumping the regulated wastewater to the inlet of the micro-electrolysis reaction tower using a lift pump. After being aerated by the aeration device in the aeration area, the regulated wastewater enters the micro-electrolysis reaction tower through the support layer; Step S2: Using the enameled copper wire coil wound around the outside of the micro-electrolysis reaction tower and the iron-carbon micro-electrolysis packing inside the tower, a magnetic field generating device is constructed. Direct current is passed through the micro-electrolysis reaction tower to form a magnetic field, and the magnitude and direction of the magnetic field are adjusted in real time according to the hydrogen ion concentration index, conductivity, chemical oxygen demand and heavy metal ion concentration of the effluent; Step S3: The regulated wastewater treated by the magnetic field overflows into the collection tank through a trapezoidal overflow weir.

[0026] A coil is wound around the outside of the micro-electrolysis reactor tower, using the micro-electrolysis packing material inside the tower as the iron core. Direct current is applied to generate a magnetic field, and the magnitude and direction of this magnetic field are periodically changed to enhance the pollutant degradation ability of the micro-electrolysis packing material. Related online water quality monitoring systems are installed at the inlet and outlet to monitor parameters such as hydrogen ion concentration, conductivity, chemical oxygen demand, and heavy metal ion concentration in real time. An intelligent integrated system is used to adjust the influent hydrogen ion concentration, magnetic field magnitude and direction, and aeration effect based on the effluent water quality, thereby improving wastewater treatment quality. To enhance the reactivity of the iron-carbon micro-electrolysis packing material and prevent caking, the iron-carbon micro-electrolysis reactor specifically involves: winding a coil around the outside of the reactor tower, using the micro-electrolysis packing material inside as the iron core; and applying direct current to create a widespread magnetic field inside the tower. The magnitude and direction of the magnetic field are periodically changed to reduce caking and passivation, thus improving the micro-electrolysis reaction treatment effect.

[0027] The intelligent control system linked to pollutant degradation efficiency is specifically designed as follows: sensors for detecting hydrogen ion concentration index, conductivity, chemical oxygen demand, and heavy metal ion concentration are installed at the effluent end to monitor the effluent water quality parameters of the wastewater treatment device in real time. Based on the monitoring results, analog signals are transmitted to the STM32 main control chip in real time. According to the embedded control algorithm program, general input / output signals and pulse width modulation signals are issued to coordinate and adjust the key reaction condition control devices in the system, including the automatic dosing device for hydrogen ion concentration index, the strength and direction of the magnetic field, and the output power of the aeration pump, thereby realizing an efficient and intelligent integrated control process for water quality treatment.

[0028] Based on the above method embodiments, as an optional embodiment, the magnetic field synergistic regulation enhanced micro-electrolysis wastewater treatment method provided in this embodiment of the invention, wherein the magnitude and direction of the magnetic field are adjusted in real time according to the hydrogen ion concentration index, conductivity, chemical oxygen demand and heavy metal ion concentration of the effluent, includes: sending a general input / output signal to the H-bridge circuit to control the enameled copper wire coil to change the direction of the magnetic field; sending a pulse width modulation signal to the metal oxide semiconductor field effect transistor driving circuit to change the current on the enameled copper wire coil and adjust the magnetic field strength.

[0029] Based on the above method embodiments, as an optional embodiment, the magnetic field synergistic regulation enhanced micro-electrolysis wastewater treatment method provided in this embodiment of the invention includes the following: the metal oxide semiconductor field effect transistor driving circuit changes the output power of the aeration pump according to the received pulse width modulation signal, thereby adjusting the aeration volume of the aeration head at the bottom of the aeration zone, and the aeration pump is connected to the aeration head through an aeration pipe.

[0030] Based on the above method embodiments, as an optional embodiment, the magnetic field coordinated regulation enhanced micro-electrolysis wastewater treatment method provided in this embodiment of the invention includes the linkage adjustment of the influent hydrogen ion concentration index, which includes: sending a general input / output signal to a solid-state relay to control the opening and closing of the automatic dosing device for the hydrogen ion concentration index in the hydrogen ion concentration index adjustment tank, and adjusting the dosing of the influent hydrogen ion concentration index.

[0031] Based on the above method embodiments, as an optional embodiment, the magnetic field synergistic regulation enhanced micro-electrolysis wastewater treatment method provided in this embodiment of the invention includes an online water quality monitoring system comprising: a hydrogen ion concentration index sensor, a conductivity sensor, a chemical oxygen demand sensor, and a heavy metal ion concentration sensor, and the reaction conditions are regulated according to the simulated signals detected by the online water quality monitoring system.

[0032] Based on the above method embodiments, as an optional embodiment, the magnetic field synergistic regulation enhanced micro-electrolysis wastewater treatment method provided in this embodiment of the invention further includes, after regulating the micro-electrolysis reaction conditions: when it is necessary to replace the iron-carbon micro-electrolysis packing of the micro-electrolysis reaction tower, the packing outlet is opened after shutdown to clean the packing; when it is necessary to repair the pipeline or aeration head in the aeration area, the pipeline inspection port is opened after shutdown for repair.

[0033] The magnetic field-coordinated enhanced micro-electrolysis wastewater treatment method provided in this invention uses a coil wound around the outside of the micro-electrolysis reaction tower to form a variable magnetic field with packing material as the iron core. This weakens the passivation film and caking phenomenon on the surface of the packing material, increasing the pollutant removal rate by 20% to 30% and shortening the reaction time by 10% to 35%. The online water quality monitoring system at the effluent end monitors parameters such as hydrogen ion concentration index and chemical oxygen demand in real time. Combined with intelligent linkage adjustment of dosing, magnetic field and aeration devices, stable and precise control of hydrogen ion concentration index is achieved. Compared with traditional manual control, the pollutant removal rate is increased by 30% to 40%, the reaction time is shortened by 20% to 30%, the labor cost and system complexity are reduced, and the automation level and treatment efficiency of wastewater treatment are improved.

[0034] This invention provides a magnetic field-coordinated enhanced micro-electrolysis wastewater treatment system, see [link to relevant documentation]. Figure 4 The system includes: a hydrogen ion concentration index regulating tank for holding wastewater; an automatic dosing device for adjusting the hydrogen ion concentration index of the wastewater; a booster pump for delivering wastewater to the inlet; an aeration head for aerating the wastewater; an aeration pump for supplying aeration gas to the aeration head; a magnetic field generator for controlling the intensity and direction of the magnetic field around the wastewater; an online water quality monitoring system for monitoring the water quality of the wastewater; and an STM32 main control chip integrated into the online water quality monitoring system for loading corresponding programs to implement the magnetic field synergistic regulation enhanced micro-electrolysis wastewater treatment method as described in any of the aforementioned method embodiments.

[0035] See Figure 4 After the physicochemical properties of the wastewater are adjusted in the hydrogen ion concentration index regulating tank 13, it is pumped to the inlet 7 by the lift pump 12. From the inlet 7, the wastewater is introduced into the aeration zone 16. In the aeration zone 16, the wastewater passes through the support layer 5 under the action of the aeration device 19 and is then sent to the micro-electrolysis reaction zone 17. In the micro-electrolysis reaction zone 17, the wastewater reacts with the iron-carbon micro-electrolysis packing 1 under the magnetic field generated by the magnetic field generator 3, resulting in treated wastewater. The treated wastewater overflows. After passing through the trapezoidal overflow weir 9 at the upper end of the micro-electrolysis reaction zone 17, the wastewater overflows through the trapezoidal overflow weir 9 and reaches the collection tank 18. The treated wastewater is then fed into the outlet 8 through the collection tank 18. The online water quality monitoring system 4 below the outlet 8 detects the effluent water quality. Based on the measured data, the online water quality monitoring system 4 intelligently integrates and adjusts the micro-electrolysis reaction-related indices of the hydrogen ion concentration index automatic dosing device 30, aeration pump 11, and magnetic field generating device 3, thereby achieving automatic adjustment of reaction-related indices within a second-level cycle.

[0036] The magnetic field generating device 3 includes a micro-electrolysis packing 1 in an iron-carbon micro-electrolysis reaction tower as the iron core of the magnetic field generating device, and an enameled copper wire coil 2 wound around the outside of the micro-electrolysis reaction tower. The enameled copper wire coil 2 is connected to a MOS drive circuit 25 and an H-bridge circuit 24. The MOS drive circuit 25 and the H-bridge circuit 24 are connected to an STM32 main control chip 23 in an online water quality monitoring system 4 to receive a general input / output signal 28 and a pulse width modulation signal 29. When the H-bridge circuit 24 receives the general input / output signal 28, it controls the enameled copper wire coil 2 to change the direction of the magnetic field. When the MOS drive circuit 25 receives the pulse width modulation signal 29, it changes the current on the enameled copper wire coil 2 to achieve the purpose of intelligently adjusting the magnitude and direction of the magnetic field according to the effluent water quality.

[0037] The aeration device includes an aeration pump 11 installed outside the reaction tower, an aeration head 10 located at the bottom of the aeration area 16 inside the micro-electrolysis reaction tower, and an aeration pipe 6 connecting the aeration pump 11 and the aeration head 10. In addition, the aeration pump 11 is connected to the MOS drive circuit 25 by an electrical circuit, and the MOS drive circuit 25 is connected to the STM32 main control chip 23 in the online water quality monitoring system 4 to receive the pulse width modulation signal 29. When the MOS drive circuit 25 receives the pulse width modulation signal 29, it will change the output power of the aeration pump to achieve the purpose of intelligently adjusting the aeration volume according to the effluent water quality.

[0038] An automatic hydrogen ion concentration index dosing device 30 is installed on the inner wall of the hydrogen ion concentration index regulating tank 13. (See attached image) Figure 5 The automatic hydrogen ion concentration index dosing device 30 is connected to a solid-state relay 4 via a circuit. The solid-state relay 4 is connected to the STM32 main control chip 23 in the online water quality monitoring system 4 to receive general input / output signals 28. When the solid-state relay 26 receives the general input / output signals 28, it will control the opening and closing of the automatic hydrogen ion concentration index dosing device 30 to achieve the purpose of intelligently adjusting the hydrogen ion concentration index value according to the effluent water quality.

[0039] Regarding aeration control, the detection status of the chemical oxygen demand (COD) sensor 21 and the heavy metal ion concentration sensor 22 is as follows: If either the COD or the heavy metal ion concentration in the water exceeds a preset threshold, an analog signal 27 is generated. When this analog signal 27 is transmitted to the STM32 main control chip 23, the STM32 main control chip 23 sends a pulse width modulation (PWM) signal 29. After the PWM signal 29 is transmitted to the MOS drive circuit 25, the aeration rate of the aeration pump 11 is increased, and the aeration rate is controlled between 1.5-3 L / min. If both the COD and the heavy metal ion concentration in the water are within the normal threshold range, no signal is emitted, and the aeration rate remains at the current state.

[0040] Regarding aeration control, the detection status of the chemical oxygen demand sensor 21 and the heavy metal ion concentration sensor 22 is as follows: if either the chemical oxygen demand or the heavy metal ion concentration in the water exceeds a preset threshold, an analog signal 27 is generated. When the analog signal 27 is transmitted to the STM32 main control chip 23, the STM32 main control chip 23 sends a pulse width modulation signal 29. After the pulse width modulation signal 29 is transmitted to the MOS drive circuit 25, the aeration rate of the aeration pump 11 is increased, and the aeration rate is controlled between 1.5-3 L / min.

[0041] If the chemical oxygen demand and heavy metal ion concentrations in the water are both within the normal threshold range, no signal will be emitted, and the aeration rate will remain at its current state.

[0042] When the treated wastewater passes through the online water quality monitoring system 4 below the outlet 8, the hydrogen ion concentration index sensor 19 installed in the online water quality monitoring system 4 detects the treated wastewater and generates an analog signal 27. The analog signal 27 is transmitted to the STM32 main control chip 23, which then issues a general-purpose input / output signal 28. This signal 28 is transmitted to the solid-state relay 26 to issue a command to adjust the hydrogen ion concentration index based on the effluent water quality. Specifically, if the detected hydrogen ion concentration index is greater than a preset threshold (e.g., 3), the analog signal 27 is generated. When this analog signal 27 is transmitted to the STM32 main control chip 23, the STM32 main control chip 23 issues a GPIO signal 28. When the GPIO signal 28 is transmitted to the solid-state relay 26, it sends a signal to activate the acidic solution dosing function of the automatic dosing device 30, which controls the hydrogen ion concentration index value.

[0043] If the water quality hydrogen ion concentration index is detected to be less than a preset threshold (e.g., 3), an analog signal 27 is generated. When the analog signal 27 is transmitted to the STM32 main control chip 23, the STM32 main control chip 23 sends a GPIO signal 28. When the GPIO signal 28 is transmitted to the solid-state relay 26, it sends a signal to control the automatic dosing device 30 of the hydrogen ion concentration index to start the alkaline solution dosing function.

[0044] If the water hydrogen ion concentration index is detected to be within the preset threshold range, no signal will be emitted, and the automatic dosing device 30 will remain in the off state.

[0045] When the iron-carbon micro-electrolysis packing 1 located in the micro-electrolysis reaction zone 17 needs to be replaced, the entire device should be shut down, and the packing outlet 14 should be opened for packing removal. When the various pipes and aeration heads 10 located in the aeration zone 16 need to be repaired or replaced, the entire device should be shut down, and the pipeline inspection port 15 should be opened for repair.

[0046] The various embodiments of this invention are implemented through programmed processing using a device with processor functionality. Therefore, in practical engineering, the technical solutions and functions of the various embodiments of this invention can be encapsulated into various modules. Based on this reality, and building upon the above embodiments, this invention provides a magnetic field-coordinated enhanced micro-electrolysis wastewater treatment device, which is used to execute the magnetic field-coordinated enhanced micro-electrolysis wastewater treatment method in the above method embodiments. See also... Figure 2 The device includes: a first main module for implementing step S1: adjusting the hydrogen ion concentration index of wastewater to obtain regulated wastewater, which is then pumped to the inlet of the micro-electrolysis reaction tower using a lift pump. The regulated wastewater is aerated by the aeration device in the aeration zone and then enters the micro-electrolysis reaction tower through the support layer. A second main module for implementing step S2: using the enameled copper wire coil wound around the outside of the micro-electrolysis reaction tower and the iron-carbon micro-electrolysis packing material inside the tower to form a magnetic field generating device, applying direct current to generate a magnetic field inside the micro-electrolysis reaction tower, and adjusting the magnetic field based on the hydrogen ion concentration index of the effluent. The first main module controls the magnitude and direction of the magnetic field in real time by adjusting the hydrogen ion concentration index, conductivity, chemical oxygen demand, and heavy metal ion concentration; the second main module implements step S3: the regulated wastewater treated by the magnetic field overflows into the collection tank through a trapezoidal overflow weir, and the hydrogen ion concentration index, conductivity, chemical oxygen demand, and heavy metal ion concentration of the effluent are detected in real time by an online water quality monitoring system below the outlet; the third main module implements step S4: based on the detection results of step S3, the hydrogen ion concentration index of the influent, the magnetic field parameters, and the aeration rate are adjusted in conjunction to regulate the micro-electrolysis reaction conditions.

[0047] The magnetic field-coordinated enhanced micro-electrolysis wastewater treatment device provided in this embodiment of the invention adopts... Figure 2 Several modules within the system utilize coils wound around the outside of the micro-electrolysis reaction tower to create a variable magnetic field with packing material as the iron core. This weakens the passivation film and caking phenomenon on the packing surface, increasing pollutant removal rate by 20% to 30% and shortening reaction time by 10% to 35%. The online water quality monitoring system at the effluent end monitors parameters such as hydrogen ion concentration index and chemical oxygen demand in real time. Combined with intelligent linkage adjustment of dosing, magnetic field, and aeration devices, it achieves stable and precise control of hydrogen ion concentration index. Compared with traditional manual control, pollutant removal rate is increased by 30% to 40%, and reaction time is shortened by 20% to 30%. This reduces labor costs and system complexity, and improves the automation level and treatment efficiency of wastewater treatment.
