Embodiments of the present invention provide a method, apparatus, device, and medium for purifying drinking water. For details on the method for purifying drinking water, please refer to... Figure 1 , Figure 1 This is a schematic flowchart of a water purification method for drinking water provided in an embodiment of the present invention. The method is applied in the controller of a purification treatment device.
[0028] Figure 1 This is a schematic flowchart of a water purification method for drinking water provided in an embodiment of the present invention. Figure 1 As shown, the method includes the following steps S110-S150.
[0029] S110. Based on the collected target site data, obtain the corresponding water purification rules.
[0030] In this embodiment, the target site data can be the water source data to be purified. Different water source data will result in different water purification rules; for example, if the calcium content of the water source is high, the backwashing time will be extended. Water purification rules matching the target site data can be obtained from a preset database based on big data technology. The database stores a large amount of water source purification data, including various water source data and corresponding optimal water purification rules. Specifically, staff can also determine the corresponding water purification rules based on practical experience.
[0031] In one embodiment, step S110 includes: obtaining water quality condition information based on target site data; and obtaining corresponding water purification rules including the number of CEB cleaning cycles based on the water quality condition information.
[0032] In this embodiment, the target site data can be the water source data to be purified. Based on the water quality conditions in the water source data, corresponding water purification rules, including the number of CEB cleaning cycles, are obtained. Different water quality conditions result in different CEB cleaning cycles. CEB (Chemical Enhanced Backwash) is a water purification technology that improves the cleaning effect of the ceramic membrane by adding chemicals (such as chlorine, acid, or alkali) to the backwash water.
[0033] In one embodiment, the purification device includes a ceramic membrane housing, in which a ceramic membrane is disposed; the purification device also includes a temperature sensor, which is network-connected to the controller. Before step S110, the device further includes: acquiring a membrane fouling rate curve of the ceramic membrane; periodically acquiring temperature information collected by the temperature sensor; acquiring the optimal membrane flux corresponding to the temperature information based on the membrane fouling rate curve; and adjusting the current membrane flux of the ceramic membrane to the optimal membrane flux.
[0034] In this embodiment, the ceramic membrane is made of α-alumina, which has high hydrophilicity and strong oxidation resistance. The permeability of the ceramic membrane decreases as the water temperature decreases. To improve the antifouling properties of the ceramic membrane, the optimal membrane flux corresponding to the temperature information can be obtained based on the membrane fouling rate curve of the ceramic membrane; where membrane flux refers to the amount of fluid passing through a unit membrane area per unit time. Adjusting the current membrane flux of the ceramic membrane to the optimal membrane flux improves the service life of the ceramic membrane.
[0035] S120. Perform water purification operations cyclically according to the water purification rules, and record the number of cycles of the water purification operations.
[0036] In this embodiment, the corresponding water purification rules, including the number of CEB cleaning cycles, are obtained based on the water quality condition information in the water source data to be purified. If the number of CEB cleaning cycles is 2, then after the number of cycles of water purification operation reaches the program set value, two CEB enhanced backwashing water purification operations are performed.
[0037] In one embodiment, step S120 includes: performing water purification operations in a cycle according to the water purification rules, including forward flushing for 30 seconds, normal water production operation for 1800 seconds, backwashing for 45 seconds, backwashing for 45 seconds, forward flushing for 25 seconds, adding chemicals for 120 seconds, soaking with chemicals for 1200 seconds, backwashing for 45 seconds, backwashing for 45 seconds, and forward flushing for 20 seconds.
[0038] In this embodiment, both forward flushing and backwashing are cleaning methods used for the ceramic membrane. By performing water purification operations for forward flushing and backwashing, contaminants on the ceramic membrane are removed, thereby restoring membrane flux. The water purification operation of adding chemicals at the top discharge can be a PAC (polyaluminium chloride) dosing operation; by adding PAC at the inlet of the purification device, the water production efficiency of the ceramic membrane is improved. PAC is a water purification material. The top discharge refers to the upper discharge pipe, and the bottom discharge refers to the lower discharge pipe; both the upper and lower discharge pipes are pipes in the purification device that connect to the ceramic membrane.
[0039] In one embodiment, the purification device includes a ceramic membrane housing, in which a ceramic membrane is disposed. The inlet end of the ceramic membrane housing is connected to a raw water tank. A PAC dosing device is disposed between the ceramic membrane housing and the raw water tank. The PAC dosing device is network-connected to the controller. Before step S120, the method further includes: acquiring the transmembrane pressure difference parameter of the ceramic membrane; acquiring the corresponding PAC dosing frequency based on the transmembrane pressure difference parameter; and controlling the PAC dosing device to perform PAC dosing operation according to the PAC dosing frequency.
[0040] In this embodiment, by installing the PAC dosing device at the inlet end of the ceramic membrane housing and controlling the PAC dosing device to perform PAC dosing operations, the membrane flux of the ceramic membrane is restored. Specifically, the corresponding PAC dosing frequency can be obtained according to the transmembrane pressure difference parameter, and the PAC dosing device can be controlled to perform PAC dosing operations according to the PAC dosing frequency; for example, the PAC dosing device can be controlled to perform water purification operations of top-discharge dosing for 120 seconds and dosing soaking for 1200 seconds.
[0041] S130. If the number of cycles of water purification operation is equal to the preset threshold, then perform the CEB enhanced backwashing water purification operation.
[0042] In this embodiment, if the water purification operation cycle is 10 times, then the corresponding number of enhanced backwashing water purification operations will be automatically executed according to the number of CEB cleaning cycles. CEB (Chemical Enhanced Backwash) is a water purification technology that improves the cleaning effect of the ceramic membrane by adding chemicals (such as chlorine, acid, or alkali) to the backwash water.
[0043] S140. Determine whether the water purification operation of CEB enhanced backwashing has been completed and obtain the judgment result.
[0044] In this embodiment, if the determination result is that the water purification operation of CEB enhanced backwashing has not been completed, then the water purification operation of CEB enhanced backwashing will continue to be performed.
[0045] S150. If the judgment result is that the water purification operation of CEB enhanced backwashing has been completed, then return to the step of repeatedly executing the water purification operation according to the water purification rules and recording the number of cycles of the water purification operation.
[0046] In this embodiment, if the judgment result is that the water purification operation of CEB enhanced backwashing has been completed, then the process returns to the step of cyclically executing the water purification operation according to the water purification rules and recording the number of cycles of the water purification operation, that is, returning to the execution step S120; the embodiment of the present invention can perform deep purification treatment on the water source by cyclically executing the water purification operation, which can effectively improve the water purification effect.
[0047] In one embodiment, the purification treatment device includes a sewage tank, in which a flow meter and a level probe are installed. The flow meter is located at the inlet of the sewage tank. Both the level probe and the flow meter are network-connected to the controller. After step S150, the device further includes: acquiring the unit inlet flow rate data collected by the flow meter and the tank level data collected by the level probe; if the unit inlet flow rate data is not within a preset unit inlet flow rate range or the tank level data is lower than a preset low level, an alarm signal for the submersible pump hose detachment is issued and the water purification operation is stopped.
[0048] In this embodiment, the sewage tank is used to collect backwash water. Sewage in the sewage tank can be discharged through a submersible pump hose. If the submersible pump hose becomes detached, the sewage in the sewage tank will be unable to be discharged. The system determines whether the submersible pump hose has become detached by acquiring the unit influent flow rate data collected by the flow meter and the tank level data collected by the level probe. If the unit influent flow rate data is not within a preset unit influent flow rate range or the tank level data is lower than a preset low level, a determination of submersible pump hose detachment is obtained. An alarm signal for submersible pump hose detachment is issued to promptly remind personnel to reinstall the submersible pump hose. The alarm signal can be an audible and visual alarm signal.
[0049] In summary, the embodiments of the present invention can perform deep purification of water sources by cyclically executing water purification operations and CEB enhanced backwashing water purification operations, which can effectively improve the water purification effect.
