[0082] It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

[0083] The embodiment of the present application provides a black hole water treatment method based on sulfide copper removal. The execution subject of the black hole water treatment method based on sulfide copper removal includes but is not limited to at least one of electronic devices capable of being configured to execute the method provided by the embodiment of the present application, such as a server, a terminal and the like.

[0084] Referring to Figure 1 Fig. 1 shows a flowchart of the black hole water treatment method based on sulfide copper removal provided by an embodiment of the present application. In the embodiment, the black hole water treatment method based on sulfide copper removal includes the following steps.

[0085] S1, confirming an ultrasonic magnetization coupling reactor and an evaporation concentration device, wherein the ultrasonic magnetization coupling reactor includes a reactor, a material feeding unit, an ultrasonic unit, a magnetic separation unit and a water quality monitoring unit, and the evaporation concentration device includes a filler evaporator, a black hole water storage device, a black hole water circulating pump, a black hole water condenser and a density measuring instrument.

[0086] It can be understood that the ultrasonic magnetization coupling reactor refers to a wastewater treatment device integrating ultrasonic treatment and magnetic field separation technology, which is used for efficient removal of copper ions and suspended solids in black hole water. The reactor refers to a container that contains mixed solution and performs physical and chemical reactions. The material feeding unit refers to an automatic controller for feeding magnetic composite materials and sulfides into the reactor, which is controlled by the ultrasonic magnetization coupling reactor control center. The magnetic separation unit refers to a device that uses a magnetic field to adsorb and remove magnetic composites (including copper sulfide precipitates), which can be an electromagnetic separator or a permanent magnet roller. In addition, the ultrasonic magnetization coupling reactor also includes a pH control unit, which refers to a device for adjusting the pH of the mixed solution in the reactor. When the pH of the mixed solution in the reactor deviates from the set pH value or pH range, the pH control unit adjusts the pH of the mixed solution by adding acid or base adjuster (such as hydrogen chloride). The water quality monitoring unit refers to a device for detecting the turbidity, copper ion concentration and oxidation-reduction potential of the mixed solution in the reactor. The evaporation and concentration device refers to a device for evaporating and concentrating subsequent black hole water to be concentrated, wherein the packed evaporator refers to a tower type device that realizes water evaporation by direct contact between low-temperature dry air and sprayed black hole water, and the black hole water storage refers to a container for storing black hole water to be concentrated and refluxed during evaporation and concentration. The black hole water circulating pump refers to a power device for transmitting black hole water among the various devices in the evaporation and concentration device. The black hole water condenser refers to a heat exchange device that allows black hole water to exchange heat with refrigerant in the black hole water condenser, causing the refrigerant to release heat and condense, while the black hole water absorbs heat and its temperature rises, forming high-temperature black hole water. The density measuring instrument refers to a device for measuring the density of black hole water stored in the black hole water storage, including black hole water to be concentrated and refluxed.

[0087] S2, obtaining black hole water to be treated, introducing the black hole water to be treated into a pre-constructed cyclone slag remover according to a preset flow rate, obtaining deslagged black hole water, and pre-oxidizing the deslagged black hole water with a pre-acquired 30% hydrogen peroxide solution based on a preset oxidation reaction time, to obtain pre-oxidized black hole water. S2, obtaining black hole water to be treated, introducing the black hole water to be treated into a pre-constructed cyclone slag remover according to a preset flow rate, obtaining deslagged black hole water, and pre-oxidizing the deslagged black hole water with a pre-acquired 30% hydrogen peroxide solution based on a preset oxidation reaction time, to obtain pre-oxidized black hole water.

[0088] It needs to be explained that the black hole water to be treated refers to black hole water that needs to be treated, wherein the black hole water refers to wastewater after the use of black hole liquid, which contains high-concentration organic amines and resin macromolecules. The organic amines and resin macromolecules in the black hole water can be used for crosslinking to prepare modified resin. At the same time, the complexing property of amino groups and metal ions in the black hole water can improve the ability of the resin to adsorb heavy metal ions such as copper and nickel, so that the black hole water can be effectively utilized, avoiding environmental pollution and improving material utilization.

[0089] Further, the flow rate refers to the volume of black-hole water passing through the cyclone slag separator per unit time, for example, 5 m3 / h. The cyclone slag separator refers to a conical container that separates solid particles by centrifugal force. The black-hole water to be treated is introduced into the cyclone slag separator at a predetermined flow rate. The cyclone slag separator separates solid particles (such as graphite, carbon black, and debris) larger than 30 microns from the black-hole water to be treated by centrifugal force. These solid particles are discharged from the bottom of the cyclone slag separator. The purpose of the slag removal operation (i.e., introduction into the cyclone slag separator) on the black-hole water to be treated is to remove most of the solid particles in the black-hole water to be treated, reduce the wear of the reactor in the subsequent ultrasonic magnetization copper removal step, and reduce the risk of evaporator fouling in the evaporation concentration stage.

[0090] As can be understood, the slag-removed black-hole water refers to the black-hole water to be treated after being subjected to slag removal by the cyclone slag separator. The oxidation reaction time refers to a constant set by a person, for example, 10 minutes. The pre-oxidized black-hole water refers to the slag-removed black-hole water after being subjected to pre-oxidation. The pre-oxidation step is as follows: the slag-removed black-hole water is added to a reaction kettle, and 30% solution is added to the reaction kettle. After the addition of materials is completed, the reaction kettle is stirred, so that the organic amine in the slag-removed black-hole water is partially oxidized to generate an intermediate that is more easily cross-linked, and the reaction time is the oxidation reaction time, which is set to 10 minutes. The pre-oxidation has the effect of: oxidizing the organic amine in the slag-removed black-hole water to an intermediate that is more easily cross-linked, thereby improving the yield of subsequent amino resin synthesis and providing more stable water quality conditions for the ultrasonic magnetization copper removal step.

[0091] S3, obtain a precipitation pH interval, and adjust the pH of the pre-oxidized black-hole water based on the precipitation pH interval to obtain target black-hole water.

[0092] As can be understood, the precipitation pH interval refers to the pH range in which copper sulfide is formed in the ultrasonic magnetization copper removal step. The target black-hole water refers to the pre-oxidized black-hole water after being subjected to pH adjustment, and the pH adjustment refers to adjusting the pH of the pre-oxidized black-hole water to be within the precipitation pH interval.

[0093] S4, prepare a magnetic composite material and obtain a sulfide, wherein the magnetic composite material comprises: magnetic particles, activated carbon powder, a flocculant, and deionized water.

[0094] As can be understood, the magnetic composite material refers to a mixture of The adsorbent is composed of magnetic particles, activated carbon powder, flocculant (polyacrylamide) and deionized water. The magnetic composite material has the following functions: cooperatively removing copper ions and suspended solids through magnetic adsorption and flocculation, and providing a carrier for copper sulfide precipitation. The sulfide refers to a chemical agent that reacts with copper ions to form a precipitate, such as sodium sulfide. The flocculant refers to a high molecular compound that promotes the aggregation of suspended particles. The function of the flocculant is to make the magnetic composite form larger flocs through bridging, thereby enhancing the settling property and magnetic separation efficiency. The flocculant can be polyacrylamide.

[0095] In detail, the preparation of the magnetic composite material includes the following steps:

[0096] Adding magnetic particles to deionized water to obtain a suspension, and using a pre-built ultrasonic disperser to ultrasonically disperse the suspension to obtain a dispersed suspension;

[0097] Adding activated carbon powder to the dispersed suspension and adjusting the pH of the added dispersed suspension to obtain an equilibrium suspension, wherein the mass ratio of activated carbon powder to magnetic particles is 1:3, and the pH of the equilibrium suspension is 7.5;

[0098] According to a predetermined flocculant ratio, the flocculant is added to the equilibrium suspension to obtain a target suspension, and the target suspension is filtered to obtain a magnetic composite material, wherein the flocculant ratio is 200:1, and the flocculant is polyacrylamide.

[0099] It can be understood that the suspension refers to deionized water into which magnetic particles are added. The ultrasonic disperser refers to a device that uses high-frequency sound waves to break up particle agglomerates. The dispersed suspension refers to the suspension after ultrasonic dispersion. The equilibrium suspension refers to the equilibrium suspension after pH adjustment. The flocculant ratio refers to the mass ratio of the flocculant to the mass of the equilibrium suspension.

[0100] S5, using an ultrasonic magnetization coupling reactor, a magnetic composite material and a sulfide to ultrasonically magnetize and remove copper from the target black hole water to obtain copper-removed black hole water, and delivering the copper-removed black hole water to a black hole water storage device in an evaporation concentration device to obtain black hole water to be concentrated.

[0101] It can be understood that the copper-removed black hole water refers to the treated black hole water after ultrasonic magnetization and copper removal, wherein the ultrasonic magnetization and copper removal refers to the cooperative effect of adsorption by the magnetic composite material and precipitation by the sulfide to remove copper ions in the treated black hole water. The advantage of this method compared to traditional chemical copper removal is that the reaction rate is fast, the sludge amount is small, and the material can be recycled through magnetic separation. The black hole water to be concentrated refers to the copper-removed black hole water in the black hole water storage device.

[0102] In detail, the target black-hole water is subjected to ultrasonic magnetization copper removal by using the ultrasonic magnetization coupling reactor, the magnetic composite material and the sulfide, to obtain the copper-removed black-hole water, including:

[0103] The material dosage of the magnetic composite material and the sulfide dosage of the sulfide are respectively set;

[0104] The magnetic composite material and the sulfide are added to the reactor by using the material dosage, the sulfide dosage and the material adding unit;

[0105] In the step of adding the magnetic composite material and the sulfide to the reactor, the target black-hole water is added to the reactor by using the pre-constructed black-hole water control valve, to obtain a target reactor, wherein the target reactor contains the target black-hole water, the magnetic composite material and the sulfide;

[0106] The magnetic composite material, the sulfide and the target black-hole water in the target reactor are mixed based on a preset mixing time, to obtain a mixed solution;

[0107] The mixed solution is subjected to ultrasonic oscillation by using the ultrasonic unit in the ultrasonic magnetization coupling reactor, to obtain a precipitated mixed solution;

[0108] In the step of ultrasonic oscillation, the precipitated mixed solution is continuously detected based on the water quality monitoring unit and a preset monitoring interval, to obtain a turbidity set, a copper ion concentration set and an oxidation-reduction potential set;

[0109] The material dosage and the sulfide dosage are respectively adjusted according to the turbidity set, the copper ion concentration set and the oxidation-reduction potential set, to obtain an adjusted material dosage and an adjusted sulfide dosage;

[0110] The adjusted material dosage and the adjusted sulfide dosage are respectively used as the material dosage and the sulfide dosage, and the step of adding the magnetic composite material and the sulfide to the reactor by using the material dosage, the sulfide dosage and the material adding unit is returned to, until a preset stop instruction is received;

[0111] The precipitated mixed solution when the stop instruction is received is recorded as a to-be-separated mixed solution, and the to-be-separated mixed solution is subjected to solid-liquid separation based on a magnetic separation unit, to obtain the copper-removed black-hole water.

[0112] It can be understood that the material addition amount and the sulfide addition amount respectively refer to the mass of the magnetic composite material subsequently added to the reactor and the mass of the sulfide subsequently added to the reactor, and the above-mentioned material addition amount and sulfide addition amount are set by relevant operators according to experience. Since the material addition amount and the sulfide addition amount need to be adjusted in real time subsequently, the material addition amount and the sulfide addition amount here do not need to be too accurate. It can be understood that the black hole water control valve refers to a valve in the reactor for controlling the injection of the black hole water to be treated. The target reactor refers to the reactor after the target black hole water, the magnetic composite material and the sulfide are added. The mixing time length refers to the time length set artificially, and the mixed solution refers to the mixed solution of the magnetic composite material, the sulfide and the target black hole water. The precipitated mixed solution refers to the mixed solution with precipitate after ultrasonic oscillation. The effect of ultrasonic oscillation is to prevent magnetic particle agglomeration, accelerate the formation of copper sulfide precipitate and enhance the flocculation effect. The monitoring interval refers to the time interval between two data sampling of the water quality monitoring unit. The turbidity set, the copper ion concentration set and the oxidation-reduction potential set respectively refer to a plurality of turbidity sets, a plurality of copper ion concentration sets and a plurality of oxidation-reduction potential sets detected by the water quality monitoring unit during the entire ultrasonic oscillation process.

[0113] It can be understood that the adjusted material addition amount refers to the material addition amount after adjustment, and the adjusted sulfide addition amount refers to the sulfide addition amount after adjustment. The stop instruction refers to an instruction artificially initiated to stop ultrasonic magnetization copper removal.

[0114] Further, the above-mentioned sulfide can chemically react with copper ions to form insoluble copper sulfide precipitate, thereby further improving the removal efficiency of copper ions. The addition of the sulfide can be coordinated with the adsorption of the magnetic composite material. The magnetic composite material can adsorb copper ions and sulfide to provide more specific surface area and more active sites for the reaction between copper ions and sulfide. This synergistic effect can accelerate the reaction process and improve the removal efficiency of copper ions. At the same time, relying solely on the adsorption of the magnetic composite material may not be able to completely remove all copper ions, especially when the concentration of copper ions is high. The addition of the sulfide can further reduce the concentration of copper ions through chemical precipitation, and the copper sulfide precipitate can form on the surface of the magnetic composite material, enhancing the magnetism and stability of the magnetic composite, which is helpful for the subsequent magnetic separation process.

[0115] In detail, the material addition amount and the sulfide addition amount are respectively adjusted according to the turbidity set, the copper ion concentration set and the oxidation-reduction potential set to obtain an adjusted material addition amount and an adjusted sulfide addition amount, comprising:

[0116] According to the turbidity set, the copper ion concentration set and the oxidation-reduction potential set, a turbidity change curve, a concentration change curve and a potential change curve are respectively constructed;

[0117] The turbidity change function, the concentration change function and the potential change function are generated based on the turbidity change curve, the concentration change curve and the potential change curve respectively.

[0118] The standard turbidity, the standard copper ion concentration and the standard oxidation-reduction potential are obtained.

[0119] The initial function time and the last function time are confirmed.

[0120] The multiple integral error terms are constructed according to the turbidity change function, the concentration change function, the potential change function, the standard turbidity, the standard copper ion concentration, the standard oxidation-reduction potential, the initial function time and the last function time, wherein the integral error terms include the turbidity error term, the concentration error term or the potential error term.

[0121] The material dosage and the sulfide dosage are adjusted respectively according to the multiple integral error terms, so as to obtain the adjusted material dosage and the adjusted sulfide dosage.

[0122] It can be understood that the turbidity change curve, the concentration change curve and the potential change curve respectively refer to the curve of the change of the turbidity concentration with time, the curve of the change of the copper ion concentration with time and the function of the change of the oxidation-reduction potential with time, and the construction of the above-mentioned curves is completed by curve fitting. The turbidity change function, the concentration change function and the potential change function respectively refer to the function expression of the turbidity change curve, the function expression of the concentration change curve and the function expression of the potential change curve, and the above-mentioned function expressions can be obtained by data fitting, for example, polynomial fitting method, least square method, etc.

[0123] Further, the standard turbidity, the standard copper ion concentration and the standard oxidation-reduction potential respectively refer to the artificially preset turbidity, copper ion concentration and oxidation-reduction potential, which can be set by fixed process standard or set according to human experience. The initial function time refers to the time when the water quality monitoring unit detects for the first time, and the last function time refers to the time when the water quality monitoring unit detects for the last time.

[0124] To explain, the turbidity error term refers to the value quantifying the deviation between the light intensity scattered by suspended particles in the black hole water (graphite, magnetic composite, copper sulfide, etc.) and the standard turbidity. The greater the turbidity error term, the greater the deviation between the light intensity scattered by suspended particles in the black hole water and the standard turbidity, i.e. the suspended load of the water body is continuously higher than the set target, and the flocculation-sedimentation process has not yet reached equilibrium. The concentration error term refers to the value quantifying the deviation between the copper ion concentration in the black hole water and the standard copper ion concentration. The greater the concentration error term, the greater the deviation between the copper ion concentration and the standard copper ion concentration, i.e. the copper ion removal is insufficient, and the precipitation or adsorption reaction has not been fully completed. The potential error term refers to the value quantifying the deviation between the oxidation-reduction potential and the standard oxidation-reduction potential. The greater the potential error term, the greater the deviation between the oxidation-reduction potential and the standard oxidation-reduction potential, i.e. the current environment in the reactor is not conducive to the generation of CuS or the stability of the magnetic composite.

[0125] In detail, the plurality of integral error terms are constructed according to the turbidity change function, the concentration change function, the potential change function, the standard turbidity, the standard copper ion concentration, the standard oxidation-reduction potential, the initial function time, and the last function time.

[0126] An exponential decay weight is constructed, and the turbidity error term is constructed according to the exponential decay weight, the turbidity change function, the standard turbidity, the initial function time, and the last function time.

[0127] The concentration error term is constructed according to the exponential decay weight, the concentration change function, the standard copper ion concentration, the initial function time, and the last function time.

[0128] The potential error term is constructed according to the exponential decay weight, the potential change function, the standard oxidation-reduction potential, the initial function time, and the last function time.

[0129] The concentration error term, the turbidity error term, and the potential error term are combined to obtain the plurality of integral error terms.

[0130] As can be understood, the exponential decay weight is , which refers to a memory factor that decreases exponentially with time.

[0131] In detail, the concentration error term, the turbidity error term, and the potential error term are respectively represented as:

[0132] ,

[0133] wherein, and represent the concentration error term, the turbidity error term, and the potential error term, respectively, represents the last function time, represents the initial function time, represents the natural constant, Indicates exponentially decaying weights. This represents the preset attenuation constant. This represents a preset time variable. Represents the turbidity change function. Represents the concentration change function. Represents the potential change function. Indicates the standard copper ion concentration. Indicates standard turbidity. Indicates the standard redox potential. Represents the differential symbol.

[0134] Furthermore, the aforementioned exponential decay weights serve to assign greater weights to more recent data (those closer to the last function's time) and less weights to older data (those farther from the last function's time), thereby constructing a biased memory with forgetting properties. Through the aforementioned integral form, historical trends can be smoothly accumulated in the time domain, suppressing noise interference. The decay constant refers to a manually set constant, and the time variable refers to the independent variable used for integration.

[0135] In detail, the adjustment of the material dosage and sulfide dosage based on multiple integral error terms to obtain the adjusted material dosage and adjusted sulfide dosage includes:

[0136] Calculate the concentration adjustment term based on the initial function time, the final function time, and the concentration error term among multiple integral error terms;

[0137] Calculate the turbidity adjustment term based on the initial function time, the final function time, and the turbidity error term among multiple integral error terms;

[0138] Calculate the potential adjustment term based on the initial function time, the final function time, and the potential error term among multiple integral error terms;

[0139] Combining the concentration adjustment term, turbidity adjustment term, and potential adjustment term yields a group of adjustment terms, wherein the concentration adjustment term, turbidity adjustment term, and potential adjustment term are respectively represented as follows:

[0140] ,

[0141] in, Indicates the concentration adjustment term. This indicates the turbidity adjustment term. Indicates the potential adjustment term;

[0142] Calculate the amount of adjusting material and the amount of adjusting sulfide based on the adjustment item group, the amount of material added, and the amount of sulfide added.

[0143] Importantly, the adjusting material dosage and the adjusting sulfide dosage are respectively represented as:

[0144]

[0145] represents the adjusting material dosage, represents the material dosage, and respectively represent a turbidity gain coefficient, a concentration gain coefficient and a potential gain coefficient of the material dosage, optionally, and are respectively set as 0.5, 0.3 and -0.2, represents the adjusting sulfide dosage, represents the sulfide dosage, and respectively represent a concentration gain coefficient, a turbidity gain coefficient and a potential gain coefficient of the sulfide dosage, optionally, and are respectively set as: 0.6, 0.2 and -0.3.

[0146] It is to be explained that the concentration adjustment term, the turbidity adjustment term and the potential adjustment term respectively refer to a value quantifying the influence of turbidity on adjustment, a value quantifying the influence of copper ion concentration on adjustment and a value quantifying the influence of oxidation-reduction potential on adjustment, and each of the adjustment terms independently contributes to the adjustment amount of the dosage. The gain coefficients (including: the turbidity gain coefficient, the concentration gain coefficient and the potential gain coefficient) determine the influence weight and direction of each adjustment term on the adjustment amount (the adjusting material dosage and the adjusting sulfide dosage), wherein the influence weight is the numerical value of the adjustment amount, and the direction is the positive or negative of the adjustment amount, wherein the adjustment amount refers to the linear combination of the corresponding adjustment term and the corresponding gain coefficient, for example: which is an adjustment amount.

[0147] Further, the values of the gain coefficients need to be preset according to system experiments or experience, for example: the material is used for adsorption and flocculation of suspended particles due to the magnetic composite material, so that the material dosage is greatly affected by the turbidity, that is, the should be set to be larger (compared to and ), and the sulfide directly reacts with copper ions to form a precipitate, that is, the sulfide dosage is mainly affected by the copper ion concentration, so that the is also set to be larger (compared to and ).

[0148] For example, when the turbidity error is high​​​​​ , need to increase the material and sulfide dosing, that is, the amount of adjustment and should be positive, that is, the corresponding gain coefficient ( and ) needs to be greater than 0 when the potential error is low , at this time, the material and sulfide dosing need to be increased (because it is not conducive to the reaction when the potential is low), and the adjustment amount and should be positive, that is, the and are negative.

[0156] If the concentration multiple is less than a preset concentration multiple threshold, the extracted black hole water is returned to the black hole water storage tank to obtain a return storage tank;

[0157] The return storage tank and the extracted black hole water are used as the black hole water storage tank and the black hole water to be concentrated respectively, and the step of transporting the black hole water to be concentrated in the black hole water storage tank to the black hole water condenser by the black hole water circulating pump is returned until the concentration multiple is not less than the concentration multiple threshold;

[0158] If the concentration multiple is not less than the concentration multiple threshold, the extracted black hole water is recorded as concentrated black hole water.

[0159] It can be understood that the initial density refers to the density of the black hole water to be concentrated. The high-temperature black hole water refers to the black hole water to be concentrated after heat exchange. The black hole water to be evaporated refers to the high-temperature black hole water sprayed on the surface of the filler evaporator. The extracted black hole water refers to the black hole water to be evaporated after low-temperature dry extraction. The target density refers to the density of the extracted black hole water. The concentration multiple refers to the ratio of the initial density to the target density. The reflux reservoir refers to the black hole water reservoir for storing the extracted black hole water.

The role of nanometer titanium dioxide is to provide a photocatalytic active site to degrade residual organic matter and enhance the stability of the resin. The role of chitosan is to complex heavy metal ions through amino groups to improve the adsorption performance of the resin.
