Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] According to one aspect of this application, this application provides a method for detecting ions in water. See also... Figure 1 The detection method 1000 includes steps S110-S130. This detection method 1000 can be executed by a detection system with computing capabilities.

[0038] In step S110, the detection system collects the potential data of at least two types of water ions in the water body to be tested and the temperature data of the water body to be tested.

[0039] According to the example embodiment, water quality ions are various inorganic and organic ions present in water bodies, which have a significant impact on the chemical properties of water and its environmental influence. The potential data of water quality ions can be the electrode potential of a specific ion in an aqueous solution, also known as redox potential or electrochemical potential. At least two types of water quality ions may include a first water quality ion and a second water quality ion.

[0040] For example, in step S110, the detection system can collect the potential data of the first water quality ion and the second water quality ion in the water body to be tested through the electrochemical detection module, and the detection system can collect the temperature data of the water body to be tested through the temperature detection module.

[0041] For example, the electrochemical detection module can be an electrochemical sensor. The electrochemical sensor includes a working electrode and a reference electrode. The electrochemical sensor generates electrical signals (e.g., current, voltage, or resistance) through oxidation or reduction reactions occurring on the surface of the working electrode. The material of the working electrode is configured to correspond to the type of a first or second water quality ion.

[0042] For example, the temperature detection module can be a negative temperature coefficient thermistor (NTC sensor). The NTC sensor can determine the corresponding temperature data by measuring the change in the resistance value of the NTC thermistor.

[0043] For example, a detection system based on an electrochemical sensor can determine the potential data of a first water quality ion by collecting the potential difference between the first working electrode and the reference electrode. Similarly, a detection system based on an electrochemical sensor can determine the potential data of a second water quality ion by collecting the potential difference between the second working electrode and the reference electrode.

[0044] For example, the first water ion can be calcium ions, and the second water ion can be magnesium ions. Therefore, the first working electrode can be a calcium working electrode, the second working electrode can be a magnesium working electrode, and the reference electrode can be an Ag / AgCl electrode.

[0045] For example, in step S110, the detection system collects:

[0046] The temperature data of the water body to be tested is T1 = 25℃.

[0047] The potential data measured by the first working electrode is E1 = E Ca = -0.01V.

[0048] The potential data measured by the second working electrode is E2 = E Mg = -0.061V.

[0049] Where T1 is the temperature data of the water body to be tested; E1 is the potential data measured by the first working electrode; E Ca E1 represents the potential data measured at the calcium working electrode; E2 represents the potential data measured at the second working electrode; E Mg The potential data is measured for the magnesium working electrode.

[0050] In step S120, the detection system determines the concentration of at least two types of water ions based on the potential data and temperature data.

[0051] According to the example embodiment, the detection system can determine the potential data of water ions using the following formula:

[0052] E actual =EE ref ;

[0053] Among them, E actualThis represents the potential data of the working electrode relative to the standard hydrogen electrode (SHE), which is the actual potential data of the working electrode; E represents the potential data measured at the working electrode. ref This is the potential data for the reference electrode.

[0054] For example, the detection system can determine the potential data of at least two water ions using the following formula:

[0055] E 1，actual =E1-E ref ;

[0056] E 2，actual =E2-E ref ;

[0057] Among them, E 1，actual E1 represents the potential data of the first working electrode relative to the standard hydrogen electrode (SHE), which is the actual potential data of the first working electrode; E2 represents the potential data measured at the first working electrode. 2，actual E1 represents the potential data of the second working electrode relative to the standard hydrogen electrode (SHE), which is the actual potential data of the second working electrode; E2 represents the potential data measured at the second working electrode; E ref This is the potential data for the reference electrode.

[0058] According to an example embodiment, the detection system can determine the concentrations of at least two water ions based on the Nikolai-Nicolov-Eisen equation.

[0059] The Nikolai Nikolov-Eisen equation is:

[0060]

[0061] Where E is the actual potential data of the working electrode; E 0 Here are the potential data for the standard electrode; R is the gas constant, with a value of 8.314 J / (mol·K); T is the absolute temperature (in K) of the water body being tested (T1); z is the charge number of the ions, with a value of 96485 C / mol; F is the Faraday constant, with a value of 96485 C / mol; C is the concentration of water ions in the water body being tested. T1 is the temperature data of the water body being tested; the detection system can determine T through unit conversion.

[0062] For example, the detection system determines the concentration of the first water quality ion and the concentration of the second water quality ion according to the following formula:

[0063]

[0064] in, C1 represents the potential data of the standard electrode of the first working electrode; C2 represents the concentration of the first water quality ion. C1 represents the potential data of the standard electrode of the second working electrode; C2 represents the concentration of the second water quality ion.

[0065] For example, in step S120, the detection system can determine the concentration of the first water quality ion (calcium ion) and the concentration of the second water quality ion (magnesium ion) according to the following formula:

[0066]

[0067] in, The potential data for the standard electrode of the calcium working electrode, i.e. [C a 2+ [This represents the concentration of calcium ions;] The potential data for the standard electrode of the magnesium working electrode, i.e. [M g 2+ [ ] represents the concentration of magnesium ions.

[0068] The detection system is known. E ref =0.197V. Therefore, the detection system determines that:

[0069]

[0070] In step S130, the detection system determines the water quality assessment index of each of the at least two water quality ions based on their respective concentrations.

[0071] According to an example embodiment, a water quality assessment index can be an indicator used to evaluate the water quality of a test water body based on the concentration of water ions. For example, the detection system can determine the water quality assessment index for each water ion by standardizing the concentration of each water ion.

[0072] Through the above embodiments, the detection method provided in this application can collect the potential data of at least two water quality ions in the water body to be tested through the electrochemical detection module, collect the temperature data of the water body to be tested through the temperature detection module, and determine the concentration of at least two water quality ions through the potential data and temperature data, and then determine their respective water quality assessment index based on the concentration of at least two water quality ions.

[0073] The detection method provided in this application can detect the concentration of water ions in the test water body without complex chemical treatment. Furthermore, the electrochemical detection module and temperature detection module have high sensitivity and rapid response, reducing detection time and enabling online detection of water ion concentration. The detection method provided in this application also determines the water quality assessment index of at least two water ions based on their respective concentrations, thereby enabling effective assessment of the water quality of the test water body.

[0074] Optionally, see Figure 2 The detection method 1000 may also include step S140.

[0075] In step S140, the detection system determines the comprehensive evaluation index of the water body to be tested based on the water quality evaluation indices of at least two water quality ions.

[0076] According to the example embodiment, the comprehensive evaluation index can be an indicator used to evaluate the water quality of the tested water body based on the concentrations of at least two water quality ions. The comprehensive evaluation index can be the Water Quality Index (WQI).

[0077] For example, the detection system can calculate the comprehensive evaluation index by proportionally calculating the water quality assessment index for each type of water ion.

[0078] According to the above embodiments, the detection method provided in this application determines the comprehensive evaluation index of the water body to be tested by using the water quality evaluation indices of at least two water quality ions, thereby enabling a comprehensive evaluation of the water quality of the water body to be tested.

[0079] Optionally, see Figure 3 Step S120 includes steps S121 and S122.

[0080] In step S121, the detection system determines the compensation potential data for at least two types of water ions based on the temperature data.

[0081] According to the example embodiment, temperature causes a potential drift in the potential data of water ions. In step S121, the detection system can calculate the compensated potential data of water ions according to the following formula:

[0082] ΔE=λ×(T1-T ref );

[0083] Where ΔE is the compensated potential data for water ions; λ is the temperature compensation coefficient; T1 is the temperature data of the water body to be measured; T ref The reference temperature can be set to 25℃.

[0084] For example, the effect coefficient of temperature on the potential data of divalent water ion selective electrodes is typically close to 0.3 mV / ℃. This means that for every 1℃ increase in temperature, the potential data of the working electrode for calcium or magnesium ions increases by approximately 0.3 mV, i.e., the temperature compensation coefficient λ1 of the working electrode is 0.3.

[0085] Temperature also affects the drift of the potential data of the reference electrode (Ag / AgCl). The effect of temperature on the potential data of the silver chloride selective electrode is typically close to -0.7 mV / ℃. This means that for every 1℃ increase in temperature, the potential of the reference electrode will decrease by approximately 0.7 mV, i.e., the temperature compensation coefficient λ2 of the reference electrode (Ag / AgCl) is -0.7.

[0086] In step S122, the detection system determines the concentrations of at least two types of water ions based on the compensation potential data, potential data, and temperature data.

[0087] According to an example embodiment, the detection system can calculate the actual potential data of the reference electrode according to the following formula:

[0088] E 实,ref =E ref -ΔE ref ;

[0089] Among them, E 实,ref The potential data is after temperature compensation for the reference electrode; E ref The potential data for the reference electrode; ΔE ref This is the compensation potential data for the reference electrode.

[0090] The detection system can calculate the actual potential data of the working electrode according to the following formula:

[0091] E 实 =E 测 -ΔE1;

[0092] Among them, E 实 The potential data is after temperature compensation for the working electrode; E 测 ΔE1 represents the measured potential data of the working electrode before temperature compensation; ΔE2 represents the compensated potential data of the working electrode.

[0093] The detection system can calculate the potential data of water ions using the following formula:

[0094] E actual =E 实 -E 实,ref =E 测 -ΔE1-E ref +ΔE ref ;

[0095] Among them, Eactual This is the potential data of the working electrode relative to the standard hydrogen electrode (SHE), which is the actual potential data of the working electrode.

[0096] According to the example embodiment, the detection system can determine the concentrations of at least two water ions based on the Nikola Nikolov-Eisen equation. The Nikola Nikolov-Eisen equation has been described in detail in step S120 and will not be repeated here.

[0097] For example, the detection system determines the concentration of the first water quality ion and the concentration of the second water quality ion according to the following formula:

[0098]

[0099] Among them, E 1,测 The potential data measured at the first working electrode before temperature compensation; E 2,测 This is the potential data measured at the second working electrode before temperature compensation.

[0100] Through the above embodiments, this application performs temperature compensation calculations on potential data using temperature data, which can calibrate the collected potential data and thereby improve the accuracy of water ion concentration.

[0101] Optionally, see Figure 4 Step S130 includes step S131.

[0102] In step S131, the detection system standardizes the concentrations based on the concentrations of at least two water ions and the preset standardization coefficients corresponding to the at least two ions, so as to obtain the water quality assessment index of each of the at least two water ions.

[0103] According to the example embodiment, the preset standardized treatment coefficient is the ratio between the concentration of water ions and the water quality assessment index. The preset standardized treatment coefficient can be customized according to user needs.

[0104] According to an example embodiment, the detection system can determine the water quality assessment index of water ions based on the following formula:

[0105]

[0106] Among them, MC norm is the water quality assessment index; k is the preset standardized treatment coefficient for water ions; C is the concentration of water ions.

[0107] For example, the detection system determines the water quality assessment index of the first water quality ion and the water quality assessment index of the second water quality ion according to the following formula:

[0108]

[0109] Among them, MC 1,norm The first water quality assessment index; k1 is the preset standardized treatment coefficient for the first water quality ion; C1 is the concentration of the first water quality ion; MC 2,norm is the second water quality assessment index; k2 is the preset standardized treatment coefficient of the second water quality ions; C1 is the concentration of the second water quality ions.

[0110] Optionally, at least two water ions include calcium ions and magnesium ions. That is, the first water ion is calcium ions and the second water ion is magnesium ions.

[0111] The range of the preset standardized treatment coefficient for calcium ions can be: 0 < α ≤ 3 mmol / L;

[0112] The range of the preset normalization treatment coefficient for magnesium ions can be: 0 < β ≤ 1 mmol / L;

[0113] Where α is the preset normalization factor for calcium ions and β is the preset normalization factor for magnesium ions.

[0114] For example, in step S131, with α = 3 mmol / L and β = 1 mmol / L, the detection system standardizes the concentrations of calcium ions and magnesium ions to determine:

[0115]

[0116]

[0117] Among them, MC Ca,norm MC is a water quality assessment index for calcium ions. Mg,norm This is a water quality assessment index for magnesium ions.

[0118] Optionally, see Figure 5 Step S140 includes step S141.

[0119] In step S141, the detection system determines the comprehensive evaluation index of the water body to be tested based on the water quality evaluation index of each of the at least two water quality ions and the preset coefficients corresponding to the at least two water quality ions.

[0120] According to the example embodiment, the preset coefficient is the ratio of the comprehensive evaluation index to the water quality evaluation index of water ions. The preset coefficient can be customized according to user needs.

[0121] According to the example embodiment, the detection system can determine the comprehensive evaluation index based on the following formula:

[0122] WQI=ω1×MC 1,norm +ω2×MC 2，norm;

[0123] ω1+ω2=1;

[0124] Wherein, WQI is the comprehensive evaluation index, ω1 is the preset coefficient for the first water quality ion; MC 1,norm The first water quality ion is the water quality assessment index; ω2 is the preset coefficient for the second water quality ion; MC 2,norm The second ion is the water quality assessment index.

[0125] According to the example embodiment, the preset coefficients of the first water quality ion and the second water quality ion can be determined based on the concentration ratio of the first water quality ion and the second water quality ion in the water body to be tested. The preset coefficients of the first water quality ion and the second water quality ion can be preset according to user needs (e.g., taste), and this application does not impose any restrictions.

[0126] For example, when ω1 is 0.6 and ω2 = 0.4, the detection system can determine the comprehensive evaluation index of the water body to be tested in step S141 as follows:

[0127] WQI=ω1×MC Ca,norm +ω2×MC Mg，norm =0.6×0.37+0.4×0.0392=0.23768.

[0128] After step S141, the detection system also determines the water quality of the water body to be tested based on the comprehensive evaluation index of the water body. If the comprehensive evaluation index exceeds the preset comprehensive evaluation index threshold, the detection system issues an alarm message to remind the user to replace the filter cartridge or maintain the filtration equipment.

[0129] According to the example embodiment, the preset comprehensive evaluation index threshold is the alarm value of a preset comprehensive water quality evaluation parameter. The preset comprehensive evaluation index threshold can be preset according to user needs (e.g., taste), and this application does not impose any restrictions.

[0130] For example, the detection system presets a comprehensive evaluation index threshold of 0.3. If the comprehensive evaluation index exceeds 0.3, the detection system issues an alarm.

[0131] According to another aspect of this application, this application provides a water ion detection system 200. See also Figure 6 The detection system 200 includes an electrochemical detection module 201, a temperature detection module 202, a processing module 203, and a display module 204.

[0132] According to an example embodiment, the electrochemical detection module 201 collects the potential data of at least two types of water ions in the water to be tested.

[0133] According to the example embodiment, water quality ions are various inorganic and organic ions present in water bodies, which have a significant impact on the chemical properties of water and its environmental influence. The potential data of water quality ions can be the electrode potential of a specific ion in an aqueous solution, also known as redox potential or electrochemical potential. At least two types of water quality ions may include a first water quality ion and a second water quality ion.

[0134] For example, the electrochemical detection module 201 collects the potential data of the first water quality ion and the second water quality ion in the water body to be tested.

[0135] For example, the electrochemical detection module 201 can be an electrochemical sensor. The electrochemical sensor includes a working electrode and a reference electrode. The electrochemical sensor generates electrical signals (e.g., current, voltage, or resistance) through oxidation or reduction reactions occurring on the surface of the working electrode. The material of the working electrode is configured to correspond to either a first water ion or a second water ion.

[0136] For example, the electrochemical detection module 201 (such as an electrochemical sensor) can determine the potential data of the first water quality ion by collecting the potential difference between the first working electrode and the reference electrode. The electrochemical detection module 201 (such as an electrochemical sensor) can determine the potential data of the second water quality ion by collecting the potential difference between the second working electrode and the reference electrode.

[0137] For example, the first water ion can be calcium ions, and the second water ion can be magnesium ions. Therefore, the first working electrode can be a calcium working electrode, and the second working electrode can be a magnesium working electrode. The reference electrode can be an Ag / AgCl electrode.

[0138] According to the example embodiment, the temperature detection module 202 collects the temperature data of the water body to be tested.

[0139] For example, the temperature detection module 202 can be a negative temperature coefficient thermistor (NTC sensor). The NTC sensor can determine the corresponding temperature data by measuring the change in the resistance value of the NTC thermistor.

[0140] According to the example embodiment, the electrochemical detection module 201 and the temperature detection module 202 can be set at the outlet of the water body to be tested.

[0141] According to the example embodiment, the processing module 203 is electrically connected to the electrochemical detection module 201 and the temperature detection module 202. Based on the potential data and temperature data, the processing module 203 determines the concentrations of at least two types of water ions.

[0142] According to the example embodiment, the processing module 203 can determine the potential data of water ions using the following formula:

[0143] E actual =EE ref ;

[0144] Among them, E actual The potential data of the working electrode relative to the standard hydrogen electrode (SHE) is the actual potential data of the working electrode; E is the potential data measured at the working electrode; E ref This is the potential data for the reference electrode.

[0145] For example, the processing module 203 can determine the potential data of at least two types of water ions using the following formula:

[0146] E 1，actual =E1-E ref ;

[0147] E 2，actual =E2-E ref ;

[0148] Among them, E 1，actual E1 represents the potential data of the first working electrode relative to the standard hydrogen electrode (SHE), which is the actual potential data of the first working electrode; E2 represents the potential data measured at the first working electrode. 2，actual E1 represents the potential data of the second working electrode relative to the standard hydrogen electrode (SHE), which is the actual potential data of the second working electrode; E2 represents the potential data measured at the second working electrode; E ref This is the potential data for the reference electrode.

[0149] According to an example embodiment, the processing module 203 can determine the concentrations of at least two types of water ions based on the Nikolai-Nicolov-Eisen equation.

[0150] The Nikolai Nikolov-Eisen equation is:

[0152] Where E is the actual potential data of the working electrode; E 0Here are the potential data for the standard electrode; R is the gas constant, with a value of 8.314 J / (mol·K); T is the absolute temperature (in K) of the water body to be tested, T1; z is the charge number of the ions, with a value of 96485 C / mol; F is the Faraday constant, with a value of 96485 C / mol; C is the concentration of water ions in the water body to be tested. T1 is the temperature data of the water body to be tested, and the processing module 203 can determine T through unit conversion.

[0153] For example, processing module 203 determines the concentration of the first water quality ion and the concentration of the second water quality ion according to the following formula:

[0154]

[0155] in, C1 represents the potential data of the standard electrode of the first working electrode; C2 represents the concentration of the first water quality ion. C1 represents the potential data of the standard electrode of the second working electrode; C2 represents the concentration of the second water quality ion.

[0156] For example, the processing module 203 can determine the concentration of the first water quality ion (calcium ion) and the concentration of the second water quality ion (magnesium ion) according to the following formula:

[0157]

[0158] in, The potential data for the standard electrode of the calcium working electrode, i.e. [C a 2+ [This represents the concentration of calcium ions;] The potential data for the standard electrode of the magnesium working electrode, i.e. [M g 2+ [ ] represents the concentration of magnesium ions.

[0159] According to an example embodiment, the processing module 203 determines the water quality assessment index for each of the at least two water quality ions based on their respective concentrations. The water quality assessment index can be an indicator used to evaluate the water quality of the water body under test based on the concentration of the water quality ions.

[0160] For example, the processing module 203 can determine the water quality assessment index for each water quality ion by standardizing the concentration of each water quality ion.

[0161] According to the example embodiment, the display module 204 is electrically connected to the processing module 203 and displays the water quality assessment index.

[0162] Through the above embodiments, this application collects the potential data of at least two water quality ions in the water body to be tested through an electrochemical detection module, collects the temperature data of the water body to be tested through a temperature detection module, determines the concentration of at least two water quality ions through the potential data and temperature data, and then determines the water quality assessment index of at least two water quality ions based on their respective concentrations.

[0163] This application enables the detection of water ion concentrations in the test water without complex chemical treatment. Furthermore, the electrochemical detection module and temperature detection module possess high sensitivity and rapid response, reducing detection time and enabling online detection of water ion concentrations.

[0164] This application determines the water quality assessment index of at least two water quality ions by measuring their respective concentrations, thereby enabling an effective assessment of the water quality of the water body to be tested.

[0165] This application displays the water quality assessment index of the water body to be tested in real time through a display module, and can remind users of the water quality status of the water body to be tested in real time.

[0166] Optionally, the processing module 203 also determines the comprehensive evaluation index of the water body to be tested based on the water quality evaluation indices of at least two water quality ions.

[0167] According to the example embodiment, the comprehensive evaluation index can be an indicator used to evaluate the water quality of the tested water body based on the concentrations of at least two water quality ions. The comprehensive evaluation index can be the Water Quality Index (WQI).

[0168] For example, the processing module 203 can calculate the comprehensive evaluation index by proportionally calculating the water quality assessment index of each water ion.

[0169] According to the above embodiments, this application determines the comprehensive evaluation index of the water body to be tested by using the water quality evaluation index of at least two water quality ions, thereby enabling a comprehensive evaluation of the water quality of the water body to be tested.

[0170] Optionally, the processing module 203 also determines the compensation potential data for at least two types of water ions based on the temperature data.

[0171] According to the example embodiment, temperature causes a potential drift in the potential data of water ions. Processing module 203 can calculate the compensated potential data of water ions according to the following formula:

[0172] ΔE=λ×(T1-T ref );

[0173] Where ΔE is the compensated potential data for water ions; λ is the temperature compensation coefficient; T1 is the temperature data of the water body to be measured; T ref The reference temperature can be set to 25℃.

[0174] For example, the effect coefficient of temperature on the potential data of divalent water ion selective electrodes is typically close to 0.3 mV / ℃. This means that for every 1℃ increase in temperature, the potential data of the working electrode for calcium or magnesium ions increases by approximately 0.3 mV, i.e., the temperature compensation coefficient λ1 of the working electrode is 0.3.

[0175] Temperature also affects the drift of the potential data of the reference electrode (Ag / AgCl). The effect of temperature on the potential data of the silver chloride selective electrode is typically close to -0.7 mV / ℃. This means that for every 1℃ increase in temperature, the potential of the reference electrode will decrease by approximately 0.7 mV, i.e., the temperature compensation coefficient λ2 of the reference electrode (Ag / AgCl) is -0.7.

[0176] According to the example embodiment, the processing module 203 determines the concentrations of at least two types of water ions based on the compensation potential data, potential data, and temperature data. The processing module 203 can calculate the actual potential data of the reference electrode according to the following formula:

[0177] E 实,ref =E ref -ΔE ref ;

[0178] Among them, E 实,ref The potential data is after temperature compensation for the reference electrode; E ref The potential data for the reference electrode; ΔE ref This is the compensation potential data for the reference electrode.

[0179] Processing module 203 can calculate the actual potential data of the working electrode according to the following formula:

[0180] E 实 =E 测 -ΔE1;

[0181] Among them, E 实 The potential data is after temperature compensation for the working electrode; E 测 ΔE1 represents the measured potential data of the working electrode before temperature compensation; ΔE2 represents the compensated potential data of the working electrode.

[0182] The processing module 203 can calculate the potential data of water ions according to the following formula:

[0183] E actual =E 实 -E 实,ref =E 测-ΔE1-E ref +ΔE ref；

[0184] Among them, E actual This is the potential data of the working electrode relative to the standard hydrogen electrode (SHE), which is the actual potential data of the working electrode.

[0185] According to an example embodiment, the processing module 203 can determine the concentrations of at least two types of water ions based on the Nikola Nikolov-Eisen equation.

[0186] For example, processing module 203 determines the concentration of the first water quality ion and the concentration of the second water quality ion according to the following formula:

[0187]

[0188] Among them, E 1,测 The potential data measured at the first working electrode before temperature compensation; E 2,测 This is the potential data measured at the second working electrode before temperature compensation.

[0189] Through the above embodiments, this application performs temperature compensation calculations on potential data using temperature data, which can calibrate the collected potential data and thereby improve the accuracy of water ion concentration.

[0190] Optionally, the processing module 203 further standardizes the concentrations based on the concentrations of at least two water quality ions and the preset standardized processing coefficients corresponding to the at least two water quality ions, so as to obtain the water quality assessment indexes of the at least two water quality ions.

[0191] The processing module 203 standardizes the concentrations of at least two water quality ions based on their respective concentrations and the preset standardization coefficients corresponding to the ions, in order to obtain the water quality assessment indexes of at least two water quality ions.

[0192] According to the example embodiment, the preset standardized treatment coefficient is the ratio between the concentration of water ions and the water quality assessment index. The preset standardized treatment coefficient can be customized according to user needs.

[0193] According to an example embodiment, the processing module 203 can determine the water quality assessment index of water ions based on the following formula:

[0194]

[0195] Among them, MC norm is the water quality assessment index; k is the preset standardized treatment coefficient for water ions; C is the concentration of water ions.

[0196] For example, the processing module 203 determines the water quality assessment index of the first water quality ion and the water quality assessment index of the second water quality ion according to the following formula:

[0197]

[0198] Among them, MC 1,norm The first water quality assessment index; k1 is the preset standardized treatment coefficient for the first water quality ion; C1 is the concentration of the first water quality ion; MC 2,norm is the second water quality assessment index; k2 is the preset standardized treatment coefficient of the second water quality ions; C1 is the concentration of the second water quality ions.

[0199] Optionally, at least two water ions include calcium ions and magnesium ions. That is, the first water ion is calcium ions and the second water ion is magnesium ions.

[0200] The range of the preset standardized treatment coefficient for calcium ions can be: 0 < α ≤ 3 mmol / L;

[0201] The range of the preset normalization treatment coefficient for magnesium ions can be: 0 < β ≤ 1 mmol / L;

[0202] Where α is the preset normalization factor for calcium ions and β is the preset normalization factor for magnesium ions.

[0203] Optionally, the processing module 203 determines the comprehensive evaluation index of the water body to be tested based on the water quality evaluation index of each of the at least two water quality ions and the preset coefficients corresponding to the at least two water quality ions.

[0204] According to the example embodiment, the preset coefficient is the ratio of the comprehensive evaluation index to the water quality evaluation index of water ions. The preset coefficient can be customized according to user needs.

[0205] According to the example embodiment, the processing module 203 can determine the comprehensive evaluation index according to the following formula:

[0206] WQI=ω1×MC 1,norm +ω2×MC 2，norm ;

[0207] ω1+ω2=1;

[0208] Wherein, WQI is the comprehensive evaluation index, ω1 is the preset coefficient for the first water quality ion; MC 1,norm The first water quality ion is the water quality assessment index; ω2 is the preset coefficient for the second water quality ion; MC 2,norm The second ion is the water quality assessment index.

[0209] According to the example embodiment, the preset coefficients of the first water quality ion and the second water quality ion can be determined based on the concentration ratio of the first water quality ion and the second water quality ion in the water body to be tested. The preset coefficients of the first water quality ion and the second water quality ion can be preset according to user needs (e.g., taste), and this application does not impose any restrictions.

[0210] According to the example embodiment, the display module 204 can also display the comprehensive evaluation index in real time, thereby reminding the user of the overall water quality of the water body to be tested in real time.

[0211] Optionally, see Figure 7 The detection system 200 also includes an alarm module 205 and a communication module 206.

[0212] According to the example embodiment, the alarm module 205 is electrically connected to the processing module 203 and the display module 204. The processing module 203 also determines the water quality of the water body under test based on its comprehensive evaluation index. If the comprehensive evaluation index exceeds a preset threshold, the processing module 203 sends an alarm command to the alarm module 205. The alarm module 205 then issues an alarm message based on the alarm command. The alarm message can be displayed on the display module 204 to remind the user to replace the filter cartridge or maintain the filtration equipment.

[0213] According to the example embodiment, the preset comprehensive evaluation index threshold is a high value or alarm value of a preset comprehensive water quality evaluation parameter. The preset comprehensive evaluation index threshold can be preset according to user needs (e.g., taste), and this application does not impose any restrictions.

[0214] For example, the processing module 203 presets the comprehensive evaluation index threshold to 0.3. When the comprehensive evaluation index exceeds 0.3, the processing module 203 sends an alarm command to the alarm module 205. The alarm module 205 then issues an alarm message based on the alarm command.

[0215] According to the example embodiment, the communication module 206 is electrically connected to the processing module 203 and the alarm module 205. The communication module 206 can send (e.g., via WIFI connection) the concentration data of at least two water quality ions in the water body to be tested, the water quality assessment index of at least two water quality ions, and the comprehensive assessment index to an external server (e.g., a cloud platform), enabling big data analysis and historical data comparison, and providing users with detailed water quality reports.

[0216] After the alarm module 205 issues an alarm message, the communication module 206 can also send the alarm message (e.g., via WIFI connection) to an external server (e.g., a cloud platform) so that users can understand the water quality status in a timely manner through remote monitoring.
