For example, as shown in FIG. 4 , the water drawing channel 203 is a water pipe, and a single water pipe extends to the vicinity of the center of the tank body of the primary treatment tank 201 , and the water pipe includes a plurality of water inlets 2032 , each of which is arranged in sequence at Different depth levels under the water surface.

The plurality of water conveyance channels 204 are respectively connected to each secondary treatment tank 202 for discharging the raw water 101 processed by the primary treatment tank 201 into any secondary treatment tank 202 . The water delivery channel 204 and the water drawing channel 203 are connected to the diverter 205 . The diverter 205 is used to adjust the communication relationship between each water-drawing channel 203 and each water-conveying channel 204. For example, the water-drawing channel 203 with the water inlet 2032 at the first depth level 301 is connected to the secondary processing unit connected to the leftmost The water delivery channel 204 of the tank 202 or the water intake channel 203 with the water inlet 2032 at the first depth level 301 is connected to the water delivery channel 204 connected to the rightmost secondary treatment tank 202 . The diverter 205 can discharge the raw water 101 into different secondary treatment tanks 202 according to different state conditions of the secondary treatment tanks 202 . The status condition may be, but is not limited to, the water level status, water quality status, or cleaning status of the secondary treatment tank 202 . In this way, the intelligent water purification system 20 can provide an online branch maintenance function.

In addition, the management system can include a machine learning algorithm to receive the status information of each treatment tank, such as water level, water quality, water purification treatment time, equipment update time, etc., so as to provide an optimization solution with the shortest water purification time or the highest water supply quality .

Existing water purification systems mostly use timed treatment methods. In other words, each treatment tank treats the raw water 101 for a certain period of time, that is, it is released to the next treatment tank, which is beneficial to control the loading state of the next treatment tank. However, according to some embodiments, the intelligent water purification system 20 of the present invention adopts a treatment method of fixed quality. In other words, each treatment tank treats the raw water 101 to the target quality standard of the tank before releasing it to the next treatment tank. As such, since the processing time is not fixed, there must be a control method to manage the loading state of the secondary processing tank 202 . In view of this, according to some embodiments, each secondary treatment tank 202 is equipped with a water level sensor for measuring the water level of the raw water 101 contained in the secondary treatment tank 202 and sending a water level signal. The controller 208 receives the water level signal to confirm whether the secondary treatment tank 202 is fully loaded or has storage space. When the controller 208 determines that any secondary treatment tank 202 still has storage space, the diverter 205 is adjusted so that the raw water 101 is discharged into the secondary treatment tank 202 . In this way, the plurality of secondary treatment tanks 202 can be used as buffer spaces to receive the raw water to be treated 101 that may be discharged at any time.

The existing water purification system mostly adopts multiple treatment tanks arranged in series. After the whole batch of raw water 101 is treated in the treatment tank, it is discharged into the next treatment tank. As such, when any treatment tank becomes contaminated, the entire batch of raw water 101 must be emptied and reprocessed. In addition, the existing water purification system has a large amount of raw water 101 per batch, so it is difficult to manage the water quality. FIG. 5 is a schematic diagram of a conventional water purification system including a water quality sensor, please refer to FIG. 5 . A water quality sensor 108 is provided to confirm the water quality of the treatment tank. The water quality sensor 108 has a certain water quality measurement range 304, and can only confirm whether the raw water 101 within the water quality measurement range 304 meets the water quality standard, and cannot confirm whether the raw water 101 outside the water quality measurement range 304 meets the water quality standard. Considering the fluidity of water, when it is judged that the raw water 101 within the water quality measuring range 304 meets the water quality standard at any time, it may be judged that the raw water 101 within the water quality measuring range 304 does not meet the water quality standard at the next time. FIG. 6 is a schematic diagram of an intelligent water purification system according to a third embodiment of the present application, please refer to FIG. 6 . According to some embodiments, the secondary treatment tank 202 is equipped with a second water quality sensor 207 for measuring the water quality of the raw water 101 contained in the secondary treatment tank 202 and sending a water quality signal. The controller 208 receives the water quality signal to confirm the water quality of the raw water 101 in the secondary treatment tank 202 . When the controller 208 determines that the water quality of the raw water 101 in any secondary treatment tank 202 does not meet the quality standard, the diverter 205 is adjusted so that the raw water 101 is not discharged into the secondary treatment tank 202 to avoid contamination. In this way, multiple secondary treatment tanks 202 can be used as buffer spaces to prevent a single pollution event from affecting the entire batch of raw water 101 . In addition, the total amount of water is distributed to a plurality of secondary treatment tanks 202 , and the range of the raw water 101 required to be monitored by the second water quality sensor 207 of each secondary treatment tank 202 is small, thereby reducing the quality of the raw water 101 in the secondary treatment tanks 202 The problem of water quality management difficulties caused by unevenness and mobility.

FIG. 7 is a schematic block diagram of an intelligent water purification system according to a fourth embodiment of the present application, please refer to FIG. 7 . According to some embodiments, the smart water purification system 20 includes a sewage treatment tank 209 connected to each of the secondary treatment tanks 202 . The controller 208 receives the water quality signal to confirm the water quality of the raw water 101 in the secondary treatment tank 202 . When the controller 208 determines that the quality of the raw water 101 in any secondary treatment tank 202 does not meet the quality standard, it controls the communication relationship between the secondary treatment tank 202 and the sewage treatment tank 209 , for example, connecting the secondary treatment tank 202 and the sewage treatment tank The water valve of the pipeline of 209 is opened, so that the raw water 101 that does not meet the quality standard is discharged into the sewage treatment tank 209. With this configuration, the intelligent water purification system 20 only needs to treat the secondary treatment tank 202 containing the raw water 101 that does not meet the quality standard, and does not need to empty the entire batch of raw water 101 in all the secondary treatment tanks 202 . According to some embodiments, the secondary treatment tank 202 directly or indirectly discharges the raw water 101 into the clean water tank 210 after processing the raw water 101 . The clean water tank 210 collects the water discharged from all the secondary treatment tanks 202 and treats it together. According to some embodiments, the sewage treatment tank 209 treats the water discharged from each secondary treatment tank 202 together, and then directly or indirectly discharges it into the primary treatment tank 201 for reprocessing.

Since the treatment tanks of the existing water purification system are arranged in series, when any treatment tank is in the cleaning state, the entire water purification system must be suspended. As a result, the water supply during cleanup is limited. Therefore, the intelligent water purification system 20 of the present invention includes a plurality of secondary treatment tanks 202. When any secondary treatment tank 202 is in a cleaning state, the other secondary treatment tanks 202 can be used as buffer spaces to receive the raw water to be treated. 101. According to some embodiments, each secondary treatment tank 202 includes a backwash device. The backwashing device is used to clean the filter material layer of the secondary treatment tank 202. For example, a certain proportion of gas mixed with clean water is poured under the filter material layer, so that the impurities deposited between the filter material layers are flushed out of the water surface. According to some embodiments, the controller 208 controls the operation of the backwash device. When the backwash device of any secondary treatment tank 202 is operating, the controller 208 adjusts the diverter 205 so that the secondary treatment tank 202 of the running backwash device is connected to the primary treatment tank 202. The communication relationship of the processing tank 201 remains closed. In this way, the raw water 101 will not flow into the secondary treatment tank 202 that is running the backwashing device, but will flow into other secondary treatment tanks 202 for treatment. According to some embodiments, the controller 208 receives the water quality signal transmitted by the second water quality sensor 207 of the secondary treatment tank 202 . When the controller 208 determines that the water quality of the raw water 101 in any secondary treatment tank 202 does not meet the quality standard, it activates the backwashing device of the secondary treatment tank 202, and adjusts the diverter 205 so that the raw water 101 is not discharged into the secondary treatment tank 202, In order to prevent the raw water 101 to be treated from being polluted and interfering with the cleaning operation.

According to some embodiments, a first pressure sensor is provided at the connection between the water delivery channel 204 and the diverter 205 , and a second pressure sensor is provided at the connection between the water delivery channel 204 and the secondary treatment tank 202 . The junction is not limited to being located just at the junction of the two. The first pressure sensor and the second pressure sensor are used to sense the water pressure in the water delivery channel 204, the first pressure sensor converts the water pressure and outputs it as a first pressure signal, and the second pressure sensor sends The water pressure is converted and output as a second pressure signal. According to some embodiments, when the controller 208 controls the diverter 205 and requires the raw water 101 to flow from the primary treatment tank 201 into the designated water delivery channel 204, if the diverter 205 is damaged and the aforementioned instructions are not executed, the raw water 101 will not flow into the designated water channel 204. Water channel 204 . In this case, the water pressure in the water channel 204 will be lower than a certain pressure threshold. Therefore, in the aforementioned situation, when the magnitude of the first pressure signal or the magnitude of the second pressure signal is lower than a certain pressure threshold, it indicates that the diverter 205 is in a fault condition. According to some embodiments, when the controller 208 controls the diverter 205 and requires the raw water 101 to flow from the primary treatment tank 201 into the designated water delivery channel 204, if the diverter 205 is not damaged and the above-mentioned instructions are executed, the raw water 101 will flow into the designated water delivery channel 204. Water channel 204 . At this time, if the water delivery channel 204 is blocked, the raw water 101 will not flow into the downstream of the water delivery channel 204 . In this case, the water pressure measured by the first pressure sensor in the water delivery channel 204 will be much higher than the water pressure measured by the second pressure sensor. Therefore, in the aforementioned situation, when the magnitude difference between the first pressure signal and the second pressure signal is greater than a specific pressure difference threshold, it means that the water delivery channel 204 is blocked. According to some embodiments, the controller 208 determines that the diverter 205 is faulty or the water delivery channel 204 is blocked, and then sends a warning signal. The warning signal can be sound, light, vibration, wired signal or wireless signal, and can be remotely viewed and communicated by users.
