[0030] Embodiment 1

[0031] Figure 1 This is a flow chart of a wastewater batch treatment method provided in the first embodiment of the present invention. This embodiment is applicable to the case of batch treatment of nickel-containing wastewater. The method can be performed by a wastewater batch treatment device. The wastewater batch treatment device can be implemented in the form of hardware and / or software. The wastewater batch treatment device can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0032] S110, when it is detected that the liquid level of the wastewater to be treated in the raw water tank reaches a first threshold, the wastewater to be treated in the raw water tank is controlled to enter the batch treatment tank.

[0033] The raw water tank is used to hold all the wastewater to be treated, which may contain heavy metal components (such as nickel, lead, chromium, etc.). The first threshold value may refer to a reference value of the liquid level of the wastewater to be treated in the raw water tank that is pre-set according to actual treatment requirements. Optionally, a liquid level sensor is pre-installed in the raw water tank, and the liquid level of the wastewater to be treated in the raw water tank is determined based on the liquid level sensor. Exemplarily, the liquid level sensor may be a radar level gauge.

[0034] In this embodiment, the liquid level height of the wastewater to be treated in the raw water tank can be detected in real time by a liquid level sensor pre-installed in the raw water tank. When it is detected that the liquid level height of the wastewater to be treated in the raw water tank reaches a first threshold, the centralized control system (such as PLC) controls the water inlet pump to start, and the wastewater to be treated in the raw water tank is discharged into the batch treatment tank through the water inlet pump. The batch treatment tank is used to batch process the wastewater to be treated in the raw water tank; the raw water tank is connected to the batch treatment tank through a first pipeline, and the water inlet pump is installed on the first pipeline.

[0035] S120, when it is detected that the liquid level of the wastewater to be treated in the batch treatment tank reaches a second threshold, the wastewater to be treated in the raw water tank is controlled to stop entering the batch treatment tank.

[0036] The second threshold value may refer to a reference value of the liquid level height of the wastewater to be treated in the batch tank that is pre-set according to actual treatment requirements, and can be used to characterize the maximum amount of wastewater that the batch tank is allowed to treat at one time. Exemplarily, the second threshold value may be set to 5 meters. Optionally, a liquid level sensor is pre-installed in the batch tank, and the liquid level height of the wastewater to be treated in the batch tank is determined based on the liquid level sensor.

[0037] In this embodiment, the liquid level height of the wastewater to be treated in the batch treatment tank can be detected in real time by a liquid level sensor pre-installed in the batch treatment tank. When it is detected that the liquid level height of the wastewater to be treated in the batch treatment tank reaches the second threshold, it indicates that the processing upper limit of the batch treatment tank has been reached. Therefore, the water inlet pump can be controlled to be closed through a centralized control system (such as PLC), thereby stopping the discharge of the wastewater to be treated in the raw water tank into the batch treatment tank.

[0038] S130, determining the drug addition information corresponding to the wastewater to be treated in the batch treatment tank; wherein the drug addition information includes the drug addition sequence and the drug addition amount.

[0039] In this embodiment, the drug addition information required for the wastewater to be treated in the batch tank can be determined by a preliminary experiment (manual small test). Optionally, determining the drug addition information corresponding to the wastewater to be treated in the batch tank includes: obtaining a preset capacity of wastewater to be treated from the batch tank as reference wastewater; determining the drug reference sequence and drug reference amount of the reference wastewater based on the pretreatment result of the reference wastewater; determining the drug addition amount corresponding to the remaining wastewater to be treated in the batch tank according to the preset capacity, the drug reference amount and the capacity of the remaining wastewater to be treated in the batch tank; determining the drug reference sequence as the drug addition sequence corresponding to the remaining wastewater to be treated in the batch tank; and determining the drug addition information corresponding to the remaining wastewater to be treated in the batch tank according to the drug addition sequence and drug addition amount corresponding to the remaining wastewater to be treated in the batch tank.

[0040] Among them, the preset capacity may refer to the capacity of the wastewater to be treated that is preset according to the actual pre-experimental requirements. Exemplarily, the preset capacity may be 500 milliliters. The reference wastewater may refer to the preset capacity of the wastewater to be treated obtained from the batch tank. The reference sequence of drugs and the reference amount of drugs may refer to the order of drug addition and the amount of drug addition of the reference wastewater, respectively. Exemplarily, assuming that the wastewater to be treated is nickel-containing wastewater, and the reference wastewater is 500 milliliters of wastewater to be treated in the batch tank, the reference sequence of drugs and the reference amount of drugs obtained by the pre-experiment are calcium chloride a gram-K8000 agent b gram-alkali solution c gram-iron salt d gram-anion e gram. The remaining wastewater to be treated may refer to other wastewater in the batch tank except the preset capacity of wastewater to be treated.

[0041] Specifically, the dosage of the drug corresponding to the remaining wastewater to be treated in the batch tank can be determined based on the ratio between the preset capacity and the capacity of the remaining wastewater to be treated in the batch tank, and the reference amount of the drug and the dosage of the drug corresponding to the remaining wastewater to be treated in the batch tank. Optionally, the dosage of the drug corresponding to the remaining wastewater to be treated in the batch tank is determined based on the preset capacity, the reference amount of the drug, and the capacity of the remaining wastewater to be treated in the batch tank, including: determining a reference ratio based on the ratio of the capacity of the remaining wastewater to be treated in the batch tank to the preset capacity; and determining the dosage of the drug corresponding to the remaining wastewater to be treated in the batch tank based on the product of the reference ratio and the reference amount of the drug.

[0042] First, the capacity of the remaining wastewater to be treated in the batch tank is divided by the preset capacity to obtain a reference ratio, and then the reference ratio is multiplied by the reference amount of the medicine to obtain the amount of medicine added corresponding to the remaining wastewater to be treated in the batch tank. Exemplarily, taking the addition of a gram of calcium chloride to 500 milliliters of reference wastewater as an example, assuming that the capacity of the remaining wastewater to be treated in the batch tank is 1 ton, the amount of calcium chloride that needs to be added to the remaining wastewater to be treated in the batch tank is: 1 ton / 500 milliliters × a gram. On the basis of determining the amount of medicine added corresponding to the remaining wastewater to be treated in the batch tank, the reference order of the medicine can be directly determined as the order of medicine addition corresponding to the remaining wastewater to be treated in the batch tank, thereby determining the medicine addition information corresponding to the remaining wastewater to be treated in the batch tank.

[0043] S140, if a wastewater treatment start event is detected, the target medicine tank is controlled to add medicine to the batch tank according to the medicine addition information, until a wastewater treatment end event is detected, at which time the target medicine tank is controlled to stop adding medicine.

[0044] Among them, the wastewater treatment start event may refer to an operation instruction for instructing the start of wastewater treatment, which may be manually input through a centralized control system (such as a PLC) (such as clicking a "start" button). The wastewater treatment end event may refer to an operation instruction for instructing the end of wastewater treatment, which may be triggered when all the drugs have been added.

[0045] In this embodiment, when the wastewater treatment start event is detected, the explosion valve is controlled to open by a centralized control system (such as PLC), and the target medicine tank is controlled to add medicine to the batch tank according to the medicine addition information based on the explosion valve, until the wastewater treatment end event is detected, the explosion valve is controlled to close, so that the target medicine tank stops adding medicine. Exemplarily, assuming that the medicines to be added are calcium chloride, K8000 agent, alkali solution, iron salt and anion, the explosion time of the above medicines can be set to 10 minutes, 60 minutes, 30 minutes, 30 minutes and 20 minutes respectively. Among them, the target medicine tank is used to hold the medicines required for wastewater treatment, and one target medicine tank holds one medicine (if there are multiple medicines, there are multiple target medicine tanks); the target medicine tank and the batch tank are connected by a second pipeline, and a flow meter is installed on the second pipeline. The flow meter on the second pipeline can be used to detect the accumulated amount of medicine added before the current moment.

[0046] Furthermore, a pH meter is placed in the batch tank to detect the pH value of the wastewater to be treated in the batch tank. For example, taking the treatment of nickel-containing wastewater as an example, after adding the alkali solution, it is necessary to ensure that the pH value of the wastewater to be treated in the batch tank is within the range of 12-13, and after adding the iron salt, it is necessary to ensure that the pH value of the wastewater to be treated in the batch tank is within the range of 7.5-8. Although theoretically, a relatively ideal wastewater treatment effect can be achieved after adding drugs to the batch tank according to the drug addition information, but considering the problems such as explosion valve failure or inaccurate flowmeter, in order to ensure the effect of wastewater treatment, after adding the alkali solution and iron salt, the pH value of the wastewater to be treated in the batch tank can be detected by a pH meter to see if it is in a reasonable pH value range. Assuming that the pH value measured by the pH meter is less than 12 after the alkali solution is added, the pH meter can feed back the actual pH value to the centralized control system (such as PLC), and then the centralized control system (such as PLC) controls the target medicine tank containing the alkali solution to continue adding alkali solution to the batch treatment tank based on the alkali solution dosage provided by the medicine addition information until the pH value reaches 12. In this way, the wastewater treatment effect can be further guaranteed based on the medicine addition information.

[0047] The technical solution of the embodiment of the present invention is to control the wastewater to be treated in the raw water tank to enter the batch treatment tank when it is detected that the liquid level of the wastewater to be treated in the raw water tank reaches the first threshold; to control the wastewater to be treated in the raw water tank to stop entering the batch treatment tank when it is detected that the liquid level of the wastewater to be treated in the batch treatment tank reaches the second threshold; to determine the drug addition information corresponding to the wastewater to be treated in the batch treatment tank; wherein the drug addition information includes the drug addition sequence and the drug addition amount; if a wastewater treatment start event is detected, control the target medicine tank to add drugs to the batch treatment tank according to the drug addition information, until the wastewater treatment end event is detected, control the target medicine tank to stop adding drugs. This technical solution can accurately control the dosage to realize automatic batch treatment of wastewater, improve the efficiency and effect of wastewater treatment, reduce the treatment cost, and reduce safety risks.

[0048] Embodiment 2

[0049] Figure 2 This is a flow chart of a wastewater batch treatment method provided in Example 2 of the present invention. This embodiment is optimized based on the above embodiment.

[0050] like Figure 2 As shown, the method of this embodiment specifically includes the following steps:

[0051] S210, when it is detected that the liquid level of the wastewater to be treated in the raw water tank reaches a first threshold, the wastewater to be treated in the raw water tank is controlled to enter the batch treatment tank.

[0052] S220, when it is detected that the liquid level of the wastewater to be treated in the batch treatment tank reaches a second threshold, the wastewater to be treated in the raw water tank is controlled to stop entering the batch treatment tank.

[0053] S230, determining the drug addition information corresponding to the wastewater to be treated in the batch treatment tank; wherein the drug addition information includes the drug addition sequence and the drug addition amount.

[0054] S240, if a wastewater treatment start event is detected, the target medicine tank is controlled to add medicine to the batch tank according to the medicine addition information, until a wastewater treatment end event is detected, at which time the target medicine tank is controlled to stop adding medicine.

[0055] Among them, the specific implementation method of S210-S240 can refer to the detailed description in S110-S140, which will not be repeated here.

[0056] S250, after detecting the wastewater treatment end event, determining the water quality test result of the wastewater to be treated in the batch treatment tank.

[0057] Among them, the water quality test result is qualified or unqualified. In this embodiment, after the wastewater treatment end event is detected, the water quality test of the wastewater to be treated in the batch treatment tank can be manually performed to determine whether the water quality test of the wastewater to be treated in the batch treatment tank is qualified (i.e., whether it meets the discharge standard), thereby determining the water quality test result of the wastewater to be treated in the batch treatment tank. Specifically, if the water quality test result is qualified, S260 is executed; if the water quality test result is unqualified, S270-S2100 are executed.

[0058] S260, controlling the wastewater to be treated in the batch treatment tank to be discharged into the target tank.

[0059] Among them, the target water tank can be used to hold the treated wastewater in the batch tank. Specifically, the mud pump can be controlled to open for 10 minutes first, and the sediment (mud) at the bottom of the batch tank can be discharged through the mud pump. Then the mud pump is controlled to be closed, and the supernatant drainage pump is controlled to be opened at the same time, and the supernatant drainage pump is controlled to discharge the treated wastewater in the batch tank into the target water tank. When it is detected that the liquid level of the treated wastewater in the batch tank is lower than the preset liquid level, in order to avoid a small amount of sediment at the bottom that affects the supernatant, the supernatant drainage pump can be controlled to be closed at this time, and the mud pump can be turned on again for timed mud discharge until the remaining treated wastewater (including sediment) in the batch tank is discharged cleanly. Among them, the liquid stored in the target water tank is wastewater that has been treated and tested qualified.

[0060] In this embodiment, in order to better balance the efficiency and accuracy of wastewater discharge, different liquid level valves are set at the liquid level heights corresponding to different liquid level thresholds to control wastewater discharge. Optionally, controlling the wastewater to be treated in the batch tank to be discharged into the target tank includes: if the liquid level of the wastewater to be treated in the batch tank is greater than or equal to the first liquid level threshold, controlling the first liquid level valve to open, and discharging the wastewater to be treated in the batch tank into the target tank through the first liquid level valve; wherein the first liquid level threshold is less than the second threshold; if the liquid level of the wastewater to be treated in the batch tank is less than the first liquid level threshold and greater than or equal to the second liquid level threshold, controlling the first liquid level valve to close and the second liquid level valve to open, and discharging the wastewater to be treated in the batch tank into the target tank through the second liquid level valve. The valve discharges the untreated wastewater in the batch tank into the target tank; wherein the second liquid level threshold is less than the first liquid level threshold; if the liquid level height of the untreated wastewater in the batch tank is less than the second liquid level threshold and greater than or equal to the third liquid level threshold, the second liquid level valve is controlled to be closed and the third liquid level valve is controlled to be opened, and the untreated wastewater in the batch tank is discharged into the target tank through the third liquid level valve; wherein the third liquid level threshold is less than the second liquid level threshold; if the liquid level height of the untreated wastewater in the batch tank is less than the third liquid level threshold, the third liquid level valve is controlled to be closed.

[0061] It should be noted that, due to the effect of gravity, the greater the liquid level height, the faster the drainage speed; conversely, the smaller the liquid level height, the slower the drainage speed. It can be understood that, since the first liquid level threshold> the second liquid level threshold> the third liquid level threshold, the drainage speed corresponding to the first liquid level valve is less than the drainage speed corresponding to the second liquid level valve and less than the drainage speed corresponding to the third liquid level valve. Among them, the liquid level corresponding to the first liquid level threshold is far away from the bottom of the batch tank, so the wastewater above this liquid level will not be affected by the bottom sediment, and the drainage speed can be accelerated by the first liquid level valve; the liquid level corresponding to the third liquid level threshold is close to the bottom of the batch tank, so the wastewater near this liquid level is easily affected by the bottom sediment, and the drainage speed can be slowed down by the third liquid level valve. For example, the first liquid level threshold, the second liquid level threshold and the third liquid level threshold can be set to 3.5 meters, 3 meters and 2.6 meters respectively.

[0062] S270, controlling the wastewater to be treated in the batch treatment tank to enter the pH adjustment tank.

[0063] The pH adjustment tank can be used to adjust the pH of the wastewater to be treated in the batch tank. Specifically, referring to the above-mentioned method of discharging to the target tank, based on the liquid level of the wastewater to be treated in the batch tank, the wastewater to be treated in the batch tank can be controlled to enter the pH adjustment tank by opening and closing the liquid level valve.

[0064] S280, determining the pH value of the wastewater to be treated in the pH adjustment tank, and determining reference adjustment chemicals based on the pH value of the wastewater to be treated in the pH adjustment tank.

[0065] The pH adjusting tank is pre-installed with a pH meter, and the pH value of the wastewater to be treated in the pH adjusting tank can be measured by the pH meter installed in the pH adjusting tank. The reference adjustment drug can refer to a drug that can adjust the pH value of the wastewater to be treated, such as an acid or an alkali.

[0066] S290, if a pH adjustment event is detected, control the reference medicine tank to add reference adjustment medicine into the pH adjustment tank until the pH value of the wastewater to be treated in the pH adjustment tank reaches a preset pH range.

[0067] The pH adjustment event may refer to an operation instruction for instructing to start pH adjustment, which may be manually input through a centralized control system (such as a PLC) (such as clicking an "adjust" button). The reference medicine tank may be used to hold reference adjustment medicines. The preset pH range may be used to characterize a qualified pH range for wastewater treatment, such as 7.5-8.

[0068] In this embodiment, when a pH adjustment event is detected, the reference medicine tank can be controlled by a centralized control system (such as a PLC) to add reference adjustment medicine to the pH adjustment tank until the pH value of the wastewater to be treated in the pH adjustment tank measured by the pH meter reaches a preset pH range, which can be seen in Figure 3 The process flow chart of automatic wastewater batch treatment is shown in the figure. The pH value in the pH adjustment tank is not Figure 3 Shown in.

[0069] S2100, controlling the wastewater to be treated in the pH adjustment tank to be discharged into the target water tank.

[0070] In this embodiment, in order to avoid the energy loss problem caused by the idling of the supernatant drainage pump due to the small amount of wastewater to be treated in the pH adjusting tank, it can be set to start the supernatant drainage pump when it is detected that the liquid level of the wastewater to be treated in the pH adjusting tank is greater than 1 meter; and to shut down the supernatant drainage pump when it is detected that the liquid level of the wastewater to be treated in the pH adjusting tank is less than 0.5 meter.

[0071] The technical solution of the embodiment of the present invention determines the water quality test results of the wastewater to be treated in the batch tank after controlling the target medicine tank to complete the addition of medicines into the batch tank according to the medicine addition information. If the test is qualified, it is directly discharged into the target water tank; if the test is unqualified, it is necessary to further adjust the pH of the wastewater with the help of a pH adjustment tank so that the adjusted pH can meet the wastewater treatment requirements. This technical solution can accurately control the dosage and the discharge of treated wastewater to realize automatic batch treatment of wastewater, improve the efficiency and effect of wastewater treatment, reduce treatment costs, and reduce safety risks.
