Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment, and more specifically to a wastewater heavy metal ion treatment device based on an electrically controlled ion exchange material. Background Technology
[0002] With the rapid development of industry, many industries such as electroplating, mining, metallurgy, and chemical engineering generate large amounts of wastewater containing heavy metal ions during their production processes. These heavy metal ions include, but are not limited to, copper (Cu). 2+ ), lead (Pb) 2+ ), mercury (Hg) 2 + ), cadmium (Cd 2+ ), chromium (Cr) 3+ Cr 6+ These substances, such as toxic substances, are highly toxic, non-biodegradable, and easily accumulate in organisms. If they are discharged directly into natural water bodies without effective treatment, they will cause serious pollution to the aquatic environment, thereby threatening the survival and reproduction of aquatic organisms. Through the food chain, they will ultimately harm human health, causing various serious health problems such as nervous system disorders, cancer, and kidney disease.
[0003] Traditional methods for treating heavy metal ions in wastewater mainly include chemical precipitation, ion exchange, adsorption, and membrane separation. Chemical precipitation removes heavy metal ions by adding chemical agents to the wastewater, causing them to form insoluble precipitates. However, this method often consumes large amounts of chemicals, generating significant amounts of sludge, resulting in high sludge treatment costs and a high risk of secondary pollution. Ion exchange utilizes ion exchange resins to react with heavy metal ions in the wastewater, thus removing them. However, traditional ion exchange resins suffer from limited exchange capacity, low selectivity, complex regeneration processes, and high regenerant consumption, limiting their large-scale application. Adsorption offers advantages such as simple operation and low cost, but the adsorbent has limited adsorption capacity, is difficult to regenerate after saturation, and is ineffective at removing low concentrations of heavy metal ions. Membrane separation effectively separates heavy metal ions, but membrane modules are expensive, prone to clogging, consume a lot of energy, and have high maintenance and operating costs.
[0004] Therefore, developing an efficient, environmentally friendly, economical, and highly selective wastewater heavy metal ion treatment technology has become an urgent need in the field of environmental protection. Utility Model Content
[0005] In view of this, the present invention provides a wastewater heavy metal ion treatment device based on an electrically controlled ion exchange material, which can be reused to solve the problems existing in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A wastewater heavy metal ion treatment device based on an electrically controlled ion exchange material includes a wastewater treatment tank, an electric field generating system, a regenerated liquid tank, and an MCU control system. The wastewater treatment tank is connected to the regenerated liquid tank. The wastewater treatment tank is provided with an electrically controlled ion exchange material filling layer. One end of the electric field generating system is connected to the electrically controlled ion exchange material filling layer, and the other end is connected to the MCU control system.
[0008] The electrically controlled ion exchange material filling layer contains micropores and exchangeable ions, including a matrix polymer, cation exchange groups, and anion exchange groups. The matrix polymer is disposed on the outside of the cation exchange membrane and the anion exchange membrane to provide mechanical strength. The cation exchange groups are connected to the anode plate, and the anion exchange groups are connected to the cathode plate. Both the anode plate and the cathode plate are connected to the electric field generating system.
[0009] Optionally, the MCU control system is also connected to the valve, which is equipped with a flow rate sensor for monitoring the valve flow rate. The MCU control system controls the electric field strength, energizing time, and timing and flow rate of the regenerated liquid based on the valve flow rate.
[0010] Optionally, the wastewater treatment tank is equipped with a catalyst system and an electrochemical sensor. Both the catalyst system and the electrochemical sensor are connected to the MCU control system. The MCU control system controls the catalyst generator according to the electrochemical sensor to add catalyst into the wastewater treatment tank.
[0011] Optionally, the catalyst system includes a spiral diverter blade, a conical nozzle, and a catalyst generator. The spiral diverter blade is installed on the inner wall of the wastewater treatment tank and is distributed in a spiral pattern. The conical nozzle is connected to the catalyst generator and is used to control the dispensing of the catalyst generator. The catalyst generator is installed at the upper end of the spiral diverter blade. The spiral diverter blade is used to increase the contact area between the catalyst and the wastewater.
[0012] Optionally, a sedimentation tank is provided at the bottom of the wastewater treatment tank, and a filter plate is installed at the connection between the wastewater treatment tank and the regenerated liquid tank to filter the sediment.
[0013] Optionally, the MCU control system is connected to a host computer to display the ion movement process and select whether to manually intervene based on the ion movement process.
[0014] Optionally, the regeneration tank is used to store the regeneration liquid. When the electro-controlled ion exchange material is saturated with adsorption, the regeneration liquid is introduced into the wastewater treatment tank to regenerate the electro-controlled ion exchange material, so that the adsorbed heavy metal ions are desorbed into the regeneration liquid, which facilitates the subsequent recovery and treatment of heavy metal ions.
[0015] Optionally, the MCU control system further includes a fault detection circuit for detecting whether a fault has occurred in the electric field generating system.
[0016] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a wastewater heavy metal ion treatment device based on electrically controlled ion exchange material, which has the following beneficial effects:
[0017] 1. Highly efficient removal of heavy metal ions: Through the electro-controlled ion exchange material filling layer, this device can efficiently remove heavy metal ions from wastewater. The micropores and exchangeable ions inside the electro-controlled ion exchange material can adsorb and exchange heavy metal ions in wastewater, effectively reducing the concentration of heavy metals in the wastewater.
[0018] 2. Recyclable: The device is equipped with a regeneration tank, which can regenerate the electrically controlled ion exchange material through the action of an electric field, restoring its ion exchange capacity. This not only extends the service life of the material but also reduces processing costs and improves overall economic efficiency.
[0019] 3. Intelligent Control: The introduction of the MCU control system makes the operation of this device more intelligent. By precisely controlling the electric field generation system, precise regulation of the electrically controlled ion exchange material filling layer can be achieved, thereby optimizing the treatment effect. At the same time, the MCU can also monitor the operating status of the equipment and promptly detect and handle faults.
[0020] 4. Energy saving and environmental protection: Compared with traditional wastewater treatment methods, this device does not require the addition of large amounts of chemical reagents during the treatment process, reducing the possibility of secondary pollution. At the same time, the ion exchange process under the action of an electric field has low energy consumption, meeting the requirements of energy saving and environmental protection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model discloses a wastewater heavy metal ion treatment device based on electrically controlled ion exchange materials, such as... Figure 1 As shown, it includes a wastewater treatment tank, an electric field generating system, a regenerated liquid tank, and an MCU control system 5. The wastewater treatment tank 2 is connected to the regenerated liquid tank 3. The wastewater treatment tank is provided with an electrically controlled ion exchange material filling layer. One end of the electric field generating system is connected to the electrically controlled ion exchange material filling layer, and the other end is connected to the MCU control system.
[0026] The electrically controlled ion exchange material filling layer contains micropores and exchangeable ions, including a matrix polymer, cation exchange groups, and anion exchange groups. The matrix polymer is disposed on the outside of the cation exchange membrane and the anion exchange membrane to provide mechanical strength. The cation exchange groups are connected to the anode plate, and the anion exchange groups are connected to the cathode plate. Both the anode plate and the cathode plate are connected to the electric field generating system.
[0027] Electro-controlled ion exchange materials contain numerous micropores that interconnect to form a channel network. The size, shape, and distribution of these micropores affect the migration rate and selectivity of ions within the membrane. Generally, the micropores need to be of suitable size to ensure smooth ion passage while avoiding reduced ion selectivity due to excessively large pore sizes. Like the mesh of a sieve, the micropores must allow qualified "particles" (ions) to pass through while blocking those that do not. A suitable microporous structure helps the ion exchange membrane better perform its selective permeation function for specific ions.
[0028] The wastewater treatment tank is equipped with an internal layer of electrically controlled ion exchange material to adsorb heavy metal ions in the wastewater. The tank has an inlet at the top and an outlet at the bottom to facilitate the inflow of wastewater and the outflow of treated water.
[0029] Electrode system: Includes an anode plate and a cathode plate, respectively disposed on both sides of the electrically controlled ion exchange material filling layer. The anode plate and cathode plate are connected to an external power source via wires, and the adsorption and desorption process of heavy metal ions by the electrically controlled ion exchange material is controlled by applying an electric field.
[0030] Furthermore, the MCU control system is also connected to valve 4, which is equipped with a flow rate sensor for monitoring the valve flow rate. The MCU control system controls the electric field strength, energizing time, and timing and flow rate of the regenerated liquid based on the valve flow rate.
[0031] Furthermore, the wastewater treatment tank is equipped with a catalyst system and an electrochemical sensor. Both the catalyst system and the electrochemical sensor are connected to the MCU control system. The MCU control system controls the catalyst generator based on the electrochemical sensor to add catalyst into the wastewater treatment tank.
[0032] Furthermore, the catalyst system includes a spiral diverter blade, a conical nozzle, and a catalyst generator. The spiral diverter blade is installed on the inner wall of the wastewater treatment tank and is distributed in a spiral pattern. The conical nozzle is connected to the catalyst generator and is used to control the dispensing of the catalyst generator. The catalyst generator is installed at the upper end of the spiral diverter blade. The spiral diverter blade is used to increase the contact area between the catalyst and the wastewater.
[0033] Furthermore, a sedimentation tank is installed at the bottom of the wastewater treatment tank, and a filter plate is installed at the connection between the wastewater treatment tank and the regenerated liquid tank to filter sediment. To further ensure that no sediment enters the regenerated liquid tank, a filter plate is installed at the connection between the wastewater treatment tank and the regenerated liquid tank. This filter plate has a specific pore size and filtration performance, capable of intercepting small sediments that may float from the sedimentation tank or have not completely settled. It is typically made of corrosion-resistant, high-strength materials, such as stainless steel filter mesh or some special polymer filter materials, to ensure its stable and reliable operation in the harsh environment of long-term contact with wastewater, thereby maintaining the normal operation and good performance of the entire wastewater treatment and regeneration system.
[0034] Furthermore, the MCU control system is connected to a host computer to display the ion movement process and select whether manual intervention is needed based on the ion movement process. As the core control component of the entire wastewater treatment system, the MCU (Microcontroller Unit) control system is responsible for monitoring and regulating each treatment stage. It connects to key components such as the wastewater treatment tank, regenerated liquid tank, and ion exchange device through a series of sensors and actuators, collecting real-time data on parameters such as solution conductivity, ion concentration, pH value, and water level. Based on preset program logic, it analyzes and processes this data, automatically controlling the operating status of related equipment, such as pump start / stop, valve opening / closing, and electric field intensity adjustment, to ensure the ion exchange process can proceed efficiently and stably, achieving effective wastewater treatment and rational utilization of the regenerated liquid.
[0035] Furthermore, the regeneration tank is used to store the regeneration liquid. When the electro-controlled ion exchange material is saturated with adsorption, the regeneration liquid is introduced into the wastewater treatment tank to regenerate the electro-controlled ion exchange material, so that the adsorbed heavy metal ions desorb into the regeneration liquid, which facilitates the subsequent recovery and treatment of heavy metal ions.
[0036] Furthermore, the MCU control system also includes a fault detection circuit for detecting whether a fault has occurred in the electric field generating system.
[0037] Furthermore, the fault detection circuit in this embodiment is specifically as follows: a voltage divider resistor network is connected across the voltage being detected, and the intermediate voltage obtained by the voltage divider is respectively connected to the non-inverting input terminals of two comparators (taking a common connection method as an example). A circuit composed of Zener diodes and resistors generates reference voltages corresponding to the upper and lower limits of the voltage, which are connected to the inverting input terminals of the two comparators. When the voltage is within the normal range, both comparators output a high level, which, after passing through a NAND gate, outputs a low level, and the output indication section does not activate. If the voltage is higher than the upper limit or lower than the lower limit, the corresponding comparator outputs a low level, which, after passing through a NAND gate, outputs a high level, triggering the output indication section to activate and indicating an abnormal voltage.
