Description

Technical Field

[0001] This invention belongs to the field of water, wastewater, sewage or sludge treatment technology, and particularly relates to a purification process for a special agent material for the treatment of environmental pollution using synergistic materials. Background Technology

[0002] Currently, modified adsorbents, functionalized catalytic media, and other synergistic materials are used to capture heavy metal complexes and organic pollutants. They are core functional components for maintaining the stable operation of wastewater treatment processes and ensuring the quality of effluent. They are also key material carriers for ensuring that industrial wastewater and urban sewage meet discharge standards. Through chemical bonding or strong electrostatic attraction with target pollutants via surface active sites, the regeneration efficiency of the reagent materials directly affects the purification continuity of the entire water treatment process chain, the compliance rate of effluent from the water treatment system, operating costs, and the level of solid waste reduction.

[0003] Existing technologies typically employ strong acid or strong alkali elution processes, utilizing acid-base adjustments to deviate the pH value of the environment from the isoelectric point of the reagent material, thereby using electrostatic repulsion to drive contaminants away from the material surface. However, when processing reagent materials with complex microporous structures or high aspect ratio pores, this elution mode based on the overall concentration gradient has intrinsic limitations. When contaminants are anchored deep within the micropores, the flow resistance inside the micropores and the hydration shielding layer at the interface hinder the penetration of eluted ions. Due to the shielding effect of the interfacial electric double layer on eluted ions, simply increasing the ionic strength of the eluent is insufficient to drive the dissociation of contaminants at deep active sites. Industry attempts have attempted to enhance mass transfer by increasing the elution flow rate or introducing ultrasonic vibrations; however, physical disturbances often only act on the shallow surface of the material and are insufficient to disrupt the stable hydration formed by the hydrogen bond network within the micropores. Increasing the concentration of the eluent or extending the elution time often induces swelling of the material skeleton, and may even cause the loss of the loaded functional components, leading to physical pulverization or degradation of the purification activity after recycling. In addition to hardware limitations, existing process control methods are insufficient in dealing with microscopic mass transfer dead zones. For example, Chinese invention patent application CN112897459A discloses a green control method for alkali metal / alkaline earth metal cation hydrolysis media for hydrogen production by hydrolysis of magnesium-based alloys. It optimizes the reaction rate by adjusting the type and concentration of cations in the hydrolysis media. Essentially, it belongs to static component regulation. When treating purification agents with complex pore structures, a single concentration adjustment method cannot generate sufficient driving load to break the fluid bridging structure in the micropores, causing the adsorbate to undergo secondary anchoring or mineralization deep in the pores, making it difficult to achieve full-depth activity reconstruction.

[0004] Therefore, the technical problem to be solved by this invention is how to provide a solution that can break the interfacial hydration stability and guide pollutants to migrate directionally from the depths of confined micropores, thereby achieving in-situ efficient restoration of the activity of water treatment agents and ensuring the water purification effect, while reducing the secondary pollution load and operating cost of the water purification system. Summary of the Invention

[0005] This invention provides a purification process for a special agent material for the treatment of environmental pollution using synergistic materials, comprising the following steps:

[0006] Step S1: Obtain the isoelectric point parameters of the special reagent material to be purified through the physical parameter detection unit, and monitor the double-layer polarization potential of the special reagent material in the saturated state with the target adsorbate component.

[0007] Step S2: Introduce a first conditioning liquid into the treatment site of the special reagent material. Adjust the hydrogen ion concentration parameter of the first conditioning liquid through a fluid kinetic energy input mechanism to improve the micro-interface of the special reagent material. The value dynamically crosses the isoelectric point to perform an interfacial charge polarity reversal between the surface of the special reagent material and the target adsorbate component, generating an electromotive force repulsion vector against the target adsorbate component.

[0008] Step S3: A second conditioning solution containing alkaline earth metal cation solutes is introduced into the treatment site. The high hydration energy ions in the second conditioning solution compete with the bound water at the interface of the special reagent material for hydration, thereby changing the interfacial polarization component of the Hofmeister sequence ions.

[0009] Step S4: Based on the ion activity gradient difference between the first conditioning liquid and the second conditioning liquid, a transient solvent hydrostatic pressure pointing towards the outside of the micropore is established in the micropore space of the special reagent material. Combined with the electromotive force repulsion vector, the fluid bridging structure inside the micropore is broken, driving the target adsorbate component stuck in the deep pore to migrate to the outside of the micropore.

[0010] Step S5: The double-layer polarization signal during the purification process is collected in real time by the logic operation control center, and the second-order rate of change of the double-layer polarization signal with respect to time is calculated. When the second-order rate of change converges to the preset steady-state threshold range, the control fluid kinetic energy input mechanism stops introducing the second regulating liquid.

[0011] Preferably, in step S2, based on the surface polarization state of the special pharmaceutical material, the injection rate of the first conditioning liquid is adjusted to adjust the micro-interface... The value changes by an amplitude of 2.5 to 5.0 units across the isoelectric point; step S2 also includes: monitoring the surface of the special reagent material after the interface charge polarity reversal. Potential, and use logic operations to control the central nervous system. The absolute value of the potential is maintained at no less than 20. .

This represents the molar concentration of monovalent metal ions. Where is the dielectric constant. Boltzmann's constant, Absolute temperature It is in the ionic valence state. The elementary charge, For the surface of special pharmaceutical materials Potential.

[0013] Preferably, the second conditioning liquid further contains a responsive vapor-generating precursor and an interface wetting modifier, wherein the responsive vapor-generating precursor is configured to... In-situ microbubble components are generated during the value fluctuation process; the interface wetting regulator is used to reduce the interfacial free energy of the surface of the special reagent material so that the second regulating liquid can penetrate into the physical contact surface between the target adsorbate component and the special reagent material.

[0014] Preferably, the first conditioning solution contains a coordination competing component, which is used for coordination competing components at the micro-interface. When the value crosses the isoelectric point, it preferentially binds to alkaline earth metal cations in the environment to inhibit the precipitation of mineralized particles at the micropore inlet of the special reagent material.

[0015] Preferably, in step S4, the conductivity difference between the first conditioning liquid and the second conditioning liquid is 15. Up to 50 .

[0016] Preferably, the second conditioning liquid is introduced into the treatment site by pulse pumping, and the frequency of the pulse pumping matches the pore size distribution characteristic frequency of the special reagent material.

[0017] Preferably, the special reagent material includes modified adsorbents or functionalized catalytic materials, and the adsorption saturation state refers to the state in which the removal rate of the target adsorbate component by the special reagent material drops to less than 30% of the initial value.

[0018] Preferably, in step S5, the double-layer polarization signal is monitored in real time by non-polarized detection electrodes installed at both ends of the processing site.

[0019] Preferably, the purification process is in the range of 20. Up to 40 The treatment was performed at the ambient temperature, and the bulk density of the specialized reagent material in the treatment site was 0.6. Up to 0.9 .

[0020] Compared with existing technologies, the purification process of the synergistic material environmental pollution treatment special agent of the present invention has the following advantages:

[0021] 1. In the treatment of environmental pollution using materials, by adjusting the hydrogen ion concentration within the system to cross the isoelectric point of the reagent material, and in conjunction with the ion exchange potential difference, pollutants are transformed from an electrostatically attractive state to an electrostatically repulsive state. This synergistic effect of interfacial charge polarity reversal and competitive ion site replacement utilizes the abrupt change in the intrinsic physicochemical properties of the interface to generate desorption power. This avoids the swelling effect or loss of loaded components caused by strong acid or strong alkali chemical immersion on the material skeleton. It achieves spontaneous dissociation of pollutants without damaging the structural stability of the material, maintaining the activity stability of the reagent material in multiple cycles. This ensures the stable retention efficiency of pollutants in the water treatment facility during long-term operation, realizes the resource recycling of core materials in the water treatment system, and eliminates the risk of water quality fluctuations caused by the performance degradation of reagent materials from the source.

[0022] 2. During the process of regulating the liquid phase environment, ions with high hydration energy are introduced to construct an interfacial hydration energy gradient. Simultaneously, transient osmotic pressure pointing outward from the material is superimposed by the difference in ionic strength. This breaks the water bridge connection formed by the hydrogen bond network inside the micropores, generating a micro-pumping effect that drives the residual liquid in the deep pores to migrate outward. This eliminates the mass transfer dead zone in the space with limited aspect ratio, allowing the potential repulsion effect to cover all effective specific surface areas of the material without damage. This ensures that the dissociated pollutants do not undergo secondary anchoring on the discharge path, achieving full-depth active reconstruction of the reagent material. This effectively prevents the risk of penetration and fluctuations in effluent quality caused by reagent deactivation during water treatment.

[0023] 3. Utilizing the activation characteristics of sacrificial ligands under specific acidic and alkaline environments, at the instant when the interface potential crosses the isoelectric point and generates a repulsive force, the sacrificial ligands preferentially bind to alkaline earth metal ions in the environment, blocking the in-situ secondary mineralization process induced by hydroxide concentration fluctuations at the micropore inlet. This active defense mechanism prevents the formation of a physical shielding layer by fine mineralization precipitation, avoiding the locking of dissociated pollutants inside the pores. While protecting the functional groups on the surface of the reagent material, it also avoids the secondary acid washing step required for descaling, reducing the pressure on solid waste treatment.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example, and the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] This invention employs a purification process for specialized reagents used in the treatment of environmental pollution through synergistic materials. Targeting reagents with complex microporous structures, the process utilizes the regulation of interfacial physicochemical properties to eliminate mass transfer dead zones and hydration shielding layers within the micropores, driving the retarded target adsorbate components to migrate to the outside of the micropores, thus achieving the reactivation of the specialized reagent material. During the purification process, the isoelectric point parameters of the reagent material to be purified are obtained through a physical parameter detection unit. Non-polarized detection electrodes installed at both ends of the treatment site are used to monitor the double-layer polarization potential of the reagent material in its saturated state with the adsorbed target adsorbate components in real time. This step establishes the initial charge reference of the material surface, providing data input for subsequent potential regulation. Due to the strong electrostatic attraction or coordination bonding between the active sites on the surface of the reagent material and the target adsorbate components, a first conditioning liquid is introduced into the treatment site. The fluid kinetic energy input mechanism adjusts the hydrogen ion concentration of the first conditioning liquid according to the isoelectric point parameters, thereby reactivating the microscopic interface of the reagent material. The value dynamically crosses the isoelectric point. The magnitude of the change in value is to This process, involving the reversal of interfacial charge polarity between the surface of the specialized reagent material and the target adsorbate component, generates an electromotive force repulsion vector against the target adsorbate component. The logic control center monitors the surface of the specialized reagent material after the interfacial charge polarity reversal. The potential is adjusted, and the injection rate of the first conditioning fluid is adjusted to make... The absolute value of the potential is not less than mV, the first conditioning solution contains a coordination competing component, used at the micro-interface. When the value crosses the isoelectric point, it preferentially binds to alkaline earth metal cations in the environment to inhibit the precipitation of mineralized particles at the micropore inlet of the special reagent material.

[0031] To overcome the mass transfer barrier created by the stable hydration layer formed by hydrogen bond networks within the micropores, the system introduces a second conditioning solution containing alkaline earth metal cation solutes into the treatment site. High-hydration-energy ions in the second conditioning solution compete with bound water at the interface of the specialized reagent material for hydration, altering the interfacial polarization component of the Hofmeister sequence ions. To determine the regulatory relationship between alkaline earth metal cations in the second conditioning solution and the interfacial polarization component, the system executes a polarization vector calibration procedure. Second conditioning solutions with different activity gradients are introduced into the treatment site. A non-polarized detection electrode is used to collect the complex conductivity signal from the surface of the specialized reagent material. The complex conductivity signal is decomposed into a real loss component and an imaginary polarization component through a logic operation control center. A mapping model between the alkaline earth metal cation concentration and the imaginary polarization component is established. Specifically, the interfacial polarization component... The quantization value is given by the formula Confirmed, among which For interface polarization components, The measured complex conductivity modulus, To determine the conductivity of the bulk solution, the logic operation control center adjusts the injection ratio of alkaline earth metal cations in the second regulating solution according to the mapping model, so that... Maintain at to Within the working range, the polarization displacement of the interface charge cloud is used to counteract the barrier to the secondary migration of pollutants to the active site, thus maintaining the monotonicity of the mass transfer driving force during the regeneration process.

[0032] This invention provides a calibration procedure for the interfacial polarization characteristics of special reagent materials. It is used to determine the injection benchmark of key components in the second conditioning solution under conditions of fluctuating background conductivity of different batches of materials or raw water. Based on the physical correlation between complex conductivity and double-layer polarization intensity in dielectric relaxation theory, a quantitative mapping between external observation signals and the polarization state inside micropores is established to eliminate background noise masking during the measurement process. The steps for constructing the process judgment quantitative mapping model are as follows: Calcium chloride solutions with concentrations of 0.01 mol / L, 0.05 mol / L, 0.1 mol / L, and 0.2 mol / L are injected into the flow cell at gradients through a fluid kinetic energy input mechanism as alkaline earth metal cation sources; the imaginary polarization component of the complex conductivity signal at 1.0 Hz is extracted at each concentration gradient. Calculate the interface polarization components Its calculation formula is ,in The interface polarization component (values ​​from 0 to 1.0). To measure the complex conductivity modulus at a given frequency, The conductivity of the bulk solution is measured by an inlet conductivity sensor; the logic operation control center uses a linear regression method to process the gradient data and establish the concentration of alkaline earth metal cations. and Mapping relation and the proportionality coefficient With intercept The data is stored in the feature storage unit as the basis for subsequent automatic adjustment of the second regulating solution ratio, and the molar concentration of alkaline earth metal cations in the second regulating solution is also stored. molar concentration of monovalent metal ions in the first conditioning solution The relationship follows the formula ,in This represents the molar concentration of alkaline earth metal cations. This represents the molar concentration of monovalent metal ions. Where is the dielectric constant. Boltzmann's constant, Absolute temperature It is in the ionic valence state. The elementary charge, For the surface of special pharmaceutical materials The second conditioning solution also contains a responsive vapor-generating precursor and an interface wetting modifier. The responsive vapor-generating precursor is used at the microscopic interface. During the value fluctuation process, in-situ microbubble components are generated. The interface wetting regulator is used to reduce the interfacial free energy of the surface of the special reagent material, so that the second regulating liquid can penetrate into the physical contact surface between the target adsorbate component and the special reagent material.

[0033] Based on the ion activity gradient difference between the first and second conditioning solutions, a transient solvent hydrostatic pressure pointing outwards is established within the micropores of the specialized pharmaceutical material. The conductivity difference between the first and second conditioning solutions is [value missing]. mS / cm to mS / cm, the second conditioning solution is introduced into the treatment site via pulse pumping, with a pulse pumping frequency of [frequency missing]. Hz to The frequency Hz matches the characteristic frequency of the pore size distribution of the special reagent material. The transient solvent fluid static pressure, combined with the electromotive force repulsion vector, breaks down the fluid bridging structure inside the micropores, driving the target adsorbate components trapped in the deep channels to migrate to the outside of the micropores. The determination of the purification endpoint is achieved by the logic operation control center acquiring the double-layer polarization signal during the purification process in real time and calculating the second-order rate of change of this signal relative to time. When it converges to the preset steady-state threshold range, the fluid kinetic energy input mechanism stops introducing the second conditioning liquid, and the purification process... to The treatment is performed at ambient temperature, and the volumetric density of the special reagent material in the treatment site is [value missing]. g / cm³ to g / cm³, through this feedback control method, can achieve precise control of the cleanliness of the internal pores of the special agent material and avoid material loss caused by excessive cleaning.

[0034] To ensure long-term stability of the purification process, the system has a built-in baseline adaptive update procedure. During the pre-rinse stage before the start of each purification cycle, the physical parameter detection unit collects the current polarization potential reference value. If three consecutive cycles If the offset exceeds 15% of the initial calibration value, the logic operation control center automatically initiates a reconstruction program, re-executing the concentration gradient calibration steps to correct measurement deviations caused by loss of functional groups or scaling on the material surface. For adsorbents with non-uniform pore size distribution, a dynamic pulse frequency matching procedure is executed. Based on the principle of restricted charge migration and diffusion within porous media, the electrical relaxation frequency within the micropores is inverted by identifying the imaginary maxima of the impedance spectrum. Specifically, after the interface charge reversal stabilizes, the frequency is swept, and the imaginary part of the impedance is recorded. With frequency Change curve; find the curve in The frequency point at the maximum value is defined as the characteristic frequency of the aperture distribution. and the pulse pumping frequency Set as The above procedures and parameter settings constitute a closed and reproducible technical path, enabling the full-depth reconstruction of the activity of special pharmaceutical materials.

[0035] Example 1: In the treatment of industrial wastewater containing high concentrations of Cu-EDTA metal chelates and nonionic surfactants, the active sites on the surface of the special reagent material are deeply occupied by the target adsorbate component, and the viscous hydration shielding layer constructed by polar molecules hinders the penetration of eluting ions, resulting in mass transfer damping within the deep micropores. The isoelectric point parameters of the special reagent material under this condition were measured using a physical parameter detection unit. for The deflection trend of the double-layer polarization potential with increasing saturation was monitored, and a concentration of [missing information] was introduced into the treatment site. The first conditioning solution, prepared with mol / L hydrochloric acid, adjusts the hydrogen ion concentration at the interface by adjusting the concentration of hydrogen ions in the first conditioning solution. The value is from the initial Dynamically switch to At the instant of crossing the isoelectric point, the interfacial charge polarity is reversed, generating an electromotive force repulsion vector against the target adsorbate component, causing the chelate to generate a ionization potential to move towards the micropore outlet.

[0036] While the electromotive force repulsion vector overcomes the electrostatic attraction, the system introduces a second conditioning liquid into the treatment site, by compounding a solution with a concentration of [missing information] in the first conditioning liquid. mol / L calcium chloride solute and added with a mass fraction of The fatty alcohol polyoxyethylene ether interface wetting regulator was obtained, wherein the molar concentration of the alkaline earth metal cation was... molar concentration of monovalent metal ions in the first conditioning solution Satisfying the relation ,in This represents the molar concentration of alkaline earth metal cations. This represents the molar concentration of monovalent metal ions. Where is the dielectric constant. Boltzmann's constant, Absolute temperature It is in the ionic valence state. The elementary charge, For the surface of special pharmaceutical materials Potential, utilizing the high hydration energy of alkaline earth metal cations to capture interfacial bound water, causing thermodynamic instability in the viscous hydration shield layer; this invention utilizes the potential between the first and second regulating liquids to... The conductivity difference of mS / cm establishes a transient hydrostatic pressure of the solvent fluid driven by the ion activity gradient inside and outside the micropores of the special reagent material, and is coordinated with a frequency of The Hz pulsed pumping transforms the elution process, which originally relied solely on chemical potential difference diffusion, into a directional flow driven by physical kinetic energy. This disrupts the fluid bridging structure within the micropores, driving the stagnant target adsorbate components to migrate out of the micropores. The logic operation control center extracts the second-order rate of change of the double-layer polarization signal with respect to time in real time and converges to the desired value based on this rate of change. The purification endpoint is determined by the steady-state threshold range, at which point the openness of the micropores inside the special reagent material is restored, and the active sites are in... Full-depth reconstruction is achieved at operating temperatures.

[0037] Example 2: In the experiment verifying the elution efficiency of complex porous synergistic materials for Cu-EDTA chelates, the system faced application bottlenecks due to uneven pore diameter distribution and extremely thick polar hydration layers. The experiment was conducted on a physical experimental platform, where the physical parameter detection unit was equipped with a resolution of [resolution missing]. unit Electrodes and sampling rate The Hz double-layer polarization signal acquisition module, and the flow control accuracy of the fluid kinetic energy input mechanism are... Furthermore, to simulate a real industrial electromagnetic environment, a signal-to-noise ratio of [value missing] is actively superimposed in the signal transmission link. dB Gaussian white noise; the setting of the core parameter sampling period is a technical consideration in achieving a balance between the sensitivity of capturing pore potential fluctuations and the data processing load of the logic operation control center. When the average pore size of the special reagent material is within nm to In the nm range, to ensure signal aliasing is avoided and to extract the second-order rate of change characteristics of the double-layer polarization signal, the sampling period is set to [value missing]. ms, this value is an engineering example obtained after applying the above logic to high-viscosity flow field conditions; the special reagent material to be purified is divided into a control group, an out-of-range control group, a partially missing control group, and an experimental group. The control group uses traditional... Immersion in mol / L hydrochloric acid, exceeding the range of control group setting micro-interface. The amplitude of the change in value across the isoelectric point is The partial missing control group did not add alkaline earth metal cations to the second conditioning solution, while the experimental group performed the process described above. For the initial load of Cu-EDTA on the surface of the special reagent material, the experimental group set three problem intensity gradients of low, medium and high to verify the gradient response characteristics of the scheme, see Table 1.

[0038] Table 1: Performance monitoring data of different experimental groups under the condition of treating wastewater containing Cu-EDTA.

[0039]

[0040] By analyzing the data of each group in Table 1, the out-of-range control group was due to... The span amplitude is lower than The lower limit of the unit leads to incomplete polarity reversal of the interfacial charge, and the measured value of the resulting electromotive force repulsion vector is insufficient to overcome the coordination bond energy between the adsorbate and the material surface, thus limiting the activity recovery rate. The performance inflection point appeared at this point, and although the partial deletion control group produced [performance] using the first conditioning solution, [the following occurred]. mV Potential was measured, but due to the lack of hydration competition between alkaline earth metal cations and bound water, the hydration shielding layer inside the micropores maintained thermodynamic stability. Contaminants experienced viscous resistance along the discharge path, resulting in a lower final activity recovery rate compared to the experimental group. The experimental group, by executing a complete process procedure, utilized the interaction between the first and second conditioning solutions... The conductivity difference of mS / cm established a [missing value] inside the channel. The transient solvent hydrostatic pressure of kPa, through the combined effect of physical kinetic energy and electromotive force repulsion vector, effectively broke the fluid bridging structure. Data showed that the measured activity recovery rate of the experimental group under different gradients was not lower than [amount missing]. Furthermore, as the initial load intensity increases, the system maintains a stable purification output by adjusting the pulse pumping frequency in real time through logic operation control center. This confirms the correlation between the dynamic crossing of isoelectric point and the ion activity gradient driving mechanism, and verifies that the purification process can utilize the reconstruction of interfacial physicochemical properties to eliminate microscopic mass transfer dead zones, enabling the application of specialized reagent materials in... to Reconstruction of activity at ambient temperature.

[0041] Example 3: This example combines Figures 1 to 2 A description of the purification process for a special agent for the treatment of environmental pollution using synergistic materials, such as... Figure 1As shown, in step S1, the process obtains the isoelectric point parameter of the special reagent material to be purified through a physical parameter detection unit and monitors the double-layer polarization potential of the special reagent material in the saturated state with the target adsorbate component. Then, in step S2, a first conditioning liquid is introduced into the treatment site of the special reagent material. The hydrogen ion concentration parameter of the first conditioning liquid is adjusted by a fluid kinetic energy input mechanism, causing the pH value of the micro-interface of the special reagent material to dynamically cross the isoelectric point, thereby performing an interfacial charge polarity reversal between the surface of the special reagent material and the target adsorbate component, generating an electromotive force repulsion vector against the target adsorbate component. Next, in step S3, a second conditioning liquid containing alkaline earth metal cation solute is introduced into the treatment site. This is achieved through the high hydration energy ions in the second conditioning liquid... Hydration competition is conducted with the bound water at the interface of the special reagent material to change the interfacial polarization component of the Hofmeister sequence ions. Step S4 is executed based on the ion activity gradient difference between the first and second conditioning liquids to establish a transient solvent hydrostatic pressure pointing outward from the micropores inside the special reagent material. Combined with the electromotive force repulsion vector, the fluid bridging structure inside the micropores is broken, driving the target adsorbate components stuck in the deep pores to migrate outward from the micropores. Finally, step S5 is executed to collect the double layer polarization signal in real time during the purification process through logic operation control center and calculate the second-order rate of change of the double layer polarization signal with respect to time. When the second-order rate of change converges to the preset steady-state threshold range, the fluid kinetic energy input mechanism is controlled to stop introducing the second conditioning liquid.

[0042] like Figure 2 As shown, the system comprises a pulse pumping system, a second conditioning liquid, a reagent material interface, the internal space of the micropores, the retarded adsorbate, and multiple interactive nodes outside the micropores. The second conditioning liquid is compounded with alkaline earth metal cations and introduced through pulse pumping at a frequency set to 0.5-1.2 Hz. When high hydration energy ions reach the interface, they trigger a hydration competition process, i.e., alkaline earth metal cations compete with bound water and change the polarization components of the Hofmeister sequence ions. The simultaneous wetting conditioning process uses an interface wetting agent to reduce the interface free energy, allowing the conditioning liquid to penetrate into the physical contact surface. An ion activity gradient is established based on a conductivity difference of 15-50 mS / cm, generating a transient static pressure pointing outward. Under the synergistic driving mechanism, this pressure interacts with the electromotive force repulsion vector, jointly breaking the fluid bridging structure and driving the adsorbate migration. At the same time, the gas phase generation process uses a responsive gas phase generation precursor to generate in-situ microbubbles to assist in breaking the viscous shielding layer, ultimately achieving the directional migration of the retarded adsorbate to the outside of the micropores and its successful detachment.

[0043] Example 4: In the engineering procedure for treating industrial circulating water containing organophosphorus chelating agents, the system faces the condition of a wide micropore size distribution of the agent material and fluctuating background electrolyte conductivity. The physical parameter detection unit operates at a frequency range of [missing information - likely related to a specific process or feature] for the special agent material to be purified. Hz to A sinusoidal signal potential sweep at Hz is used to extract the imaginary extreme points of the system impedance spectrum in real time through logic operation control. Based on the correlation between the mechanical resonance frequency of the fluid bridging structure inside the micropores of the special pharmaceutical material and its confined diffusion impedance relaxation characteristics, the sweep frequency at which the imaginary part of the impedance reaches its peak value is determined as the pore size distribution characteristic frequency. The pulse pumping frequency that sends the fluid kinetic energy input mechanism into the second regulating fluid Set as ; using a non-polarized detection electrode to Voltage sequences are acquired at sampling intervals of ms. The logic operation control center call order is The moving average filter processes the original voltage sequence to remove power frequency crosstalk from the characteristic response. The processed signal is then subjected to discrete difference operations to obtain the second-order rate of change of the double-layer polarization signal. The calculation formula is as follows: ,in This is the measured polarization potential value at the current sampling point. This is the measured value of the polarization potential at the sampling point at the previous moment. This is the measured value of the polarization potential at the sampling point at the previous moment. This refers to the sampling time step; the system collects data during the initial stage before introducing the second conditioning fluid. sampling points The average value is used as the initial perturbation reference. And set the steady-state threshold of the purification endpoint as When continuous Within each sampling period When all values ​​are less than the steady-state threshold, the logic operation control center determines that the deep pores of the special agent material have reached a fully open state and controls the fluid kinetic energy input mechanism to stop introducing the regulating liquid.

[0044] The above process specification is in the case of changes in the porosity of the pharmaceutical material. When operating under fluctuating deviation conditions, the system will automatically adjust the pulse pumping frequency to...

This enabled in-situ reconstruction of the internal pore connectivity of specialized reagent materials, maintaining the water treatment system's... Long-term operational stability under ambient temperature.

[0045] Example 5: In a treatment system deploying iron-based modified activated carbon reagent materials, the system executes a material property calibration procedure, uses a physical parameter detection unit to measure the electro-controlled ion exchange capacity of the special reagent material, and then measures it at a constant temperature. Continuous data collection in the environment The equilibrium potentials at different hydrogen ion concentrations were established, the hydrogen ion activity at zero charge density was determined, and the measured isoelectric points of each batch were calculated. The logic operation control center stores the measured value into the feature storage unit as the logical starting point for adjusting the injection rate of the first regulating fluid, and the specific adjustment step size... Satisfying the relation ,in For the injection rate increment, For the target pH level, These are the measured values ​​of the isoelectric point for the batch. The rate of change of polarization potential over time. The first proportionality coefficient, This is the second proportionality coefficient.

[0046] When the system faces a raw water background conductivity exceeding In high-salinity environments with a concentration of S / cm, to reduce the masking effect of background ions on the double-layer polarization signal, the system executes an on-site background reference compensation procedure. Before introducing the first conditioning fluid, the physical parameter detection unit collects the original reference voltage under static conditions. The voltage is then stored as a zero offset in the logic operation control center, based on the total dissolved solids concentration of the raw water. The injection ratio of alkaline earth metal cations in the second conditioning solution was adjusted to achieve the corrected concentration. To compensate for the potential decay caused by background ions occupying the diffusion layer, the fluid kinetic energy input mechanism performs periodic zero-point calibration based on the dynamic response characteristics of the double-layer polarization signal, eliminating the judgment deviation caused by electrode surface polarization drift and maintaining the activity reconstruction stability of the purification process under varying background ion strength.

[0047] Example 6: In an engineering scenario involving pre-deployment calibration of novel mesoporous modified adsorbent materials, the system faces fluctuations in surface functional group density due to manufacturing processes. The physical parameter detection unit executes a filling density calibration procedure, establishing a density at both ends of the processing site by adjusting the fluid kinetic energy input mechanism. MPa to The pressure gradient is MPa, and the fill volume density is determined using the flow resistance data fed back by the pressure sensor. g / cm³; The dynamic response coefficient determination procedure was executed, introducing a concentration step of g / cm³ to the treatment site. An acidic pulse of mol / L is applied, and the logic operation control center acquires the voltage offset of the double-layer polarization signal in real time. The response step relationship is determined using a linear regression method. The parameters in, where For the injection rate increment, The first proportionality coefficient has a value of [value] under this operating condition. , For the target pH level, These are the measured values ​​of the isoelectric point for the batch. This is the second proportionality coefficient, and its value under this working condition is... , The above parameters, representing the rate of change of polarization potential over time, are stored in the feature storage unit as the logic reference for subsequent purification cycles.

[0048] When the system encounters situations where microbubbles are introduced due to disturbances in the water supply pipeline or mechanical vibrations of the circulating pump, in order to eliminate the false triggering of the endpoint determination logic by non-chemical desorption factors, the system executes a signal consistency fault-tolerant verification procedure. The logic operation control center calculates the second-order rate of change of the double-layer polarization signal. At the same time, extract length of The potential fluctuation sequence for each sampling period is calculated, and its standard deviation is calculated. When the observed instantaneous second rate of change When the value enters the steady-state threshold range, the logic operation control center initiates secondary feature matching logic to verify whether the potential fluctuation variance within the current sampling window is stable. mV² to Within the distribution range of mV², if the variance data deviates from this range, it is determined to be physical noise interference, and the pumping state of the second conditioning fluid is maintained until continuous The statistical characteristics within each sampling period all meet the equilibrium criterion. At this point, the adsorbate components deep within the micropores of the special reagent material complete directional migration, and the system achieves adaptive identification of the purification endpoint when treating wastewater components containing multi-component surfactants.
