Description

Technical Field

[0001] This invention relates to a water quality control system and method for real-time feedback between peripheral monitoring and microcirculation, and relates to the field of water quality monitoring. Background Technology

[0002] Drinking water is an essential substance for human life. The quality of drinking water is directly related to human health. In recent years, with the rapid development of society, economy, and water purification technology, the quality of tap water leaving treatment plants has significantly improved. However, water quality deterioration can occur during the distribution and transportation of drinking water, especially in building water supply systems, leading to a decline in water quality at the user end, and even serious water quality problems such as discoloration and excessive levels of pathogenic microorganisms that threaten public health.

[0003] Currently, most residents use tap water directly for cleaning and heating for drinking, without secondary treatment or end-user water quality monitoring. This makes it difficult to guarantee the quality of their drinking water. For example, water quality problems such as microbial contamination, which are difficult to detect, pose significant risks. A few residents install home water purification systems, but the ratio of wastewater to purified water in these systems is generally between 1:1 and 4:1, which cannot be adjusted according to the tap water quality, resulting in substantial water waste. Furthermore, residents do not monitor the quality of the water output from their purification systems. When these systems malfunction or even cause secondary pollution, this also creates safety hazards.

[0004] Therefore, water quality monitoring at the user end and real-time feedback water quality control are crucial to ensuring the safety of residents' water use. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, in response to the above-mentioned problems, the object of the present invention is to provide a water quality control system and method capable of continuous automatic online monitoring of water quality and real-time water purification through terminal monitoring and microcirculation feedback.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0007] In a first aspect, the present invention provides a water quality control system for real-time feedback between terminal monitoring and microcirculation, the system comprising:

[0008] Test pipelines are used to transport and distribute incoming water quality fluid samples;

[0009] A monitoring device is installed on the test pipeline to monitor the residual chlorine signal, dissolved oxygen signal and / or turbidity signal of the water fluid sample;

[0010] A flushing microcirculation unit is installed at the water inlet end of the test pipe and is used to flush the test pipe and perform microcirculation of water quality.

[0011] A trigger-type purification unit is installed on the test pipeline for purifying water quality;

[0012] A measuring device is used to collect data from the monitoring device and upload it to a server. The server analyzes the monitored residual chlorine signal, dissolved oxygen signal and / or turbidity signal, and controls the flushing microcirculation unit or trigger-type purification unit to work according to the analysis results, so as to purify and regulate the water quality.

[0013] In one possible implementation, a supply device is also included, which is used to supply a corresponding water quality fluid sample stream from at least one of a plurality of inlets selected from the water supply network.

[0014] In one possible implementation, the flushing microcirculation unit employs a booster pump.

[0015] In one possible implementation, the triggered purification unit employs a nanofiltration device.

[0016] In one possible implementation, the monitoring device includes a residual chlorine monitoring sensor, a dissolved oxygen monitoring sensor, and a turbidity monitoring sensor, wherein:

[0017] The residual chlorine monitoring sensor is used to monitor the residual chlorine signal of the water quality fluid sample stream;

[0018] The dissolved oxygen monitoring sensor is used to monitor the dissolved oxygen signal of the water quality fluid sample flow;

[0019] The turbidity monitoring sensor is used to monitor the turbidity signal of the water quality fluid sample stream.

[0020] In one possible implementation, it also includes a first automatic control valve to a third automatic control valve, a purification pipeline and a flow pipeline, each of the automatic control valves being connected to a PLC;

[0021] The test pipeline is provided with a purification pipeline and a flow pipeline connected in parallel. The purification pipeline is provided with the first automatic control valve and the nanofiltration device in sequence. The flow pipeline is provided with a second automatic control valve. When the nanofiltration device is started, the first automatic control valve opens. The second automatic control valve is normally open and closes when the nanofiltration device needs to be started. The third automatic control valve is located at the end of the test pipeline. When the water quality exceeds the standard and the booster pump needs to flush the pipeline, it is opened for drainage.

[0022] In one possible implementation, a flow monitoring sensor is also installed on the test pipe located at the front end of the third automatic control valve.

[0023] In one possible implementation, a power supply is also included, which is used to supply power to the various electrical devices.

[0024] Secondly, the present invention also provides a control method based on a water quality control system with real-time feedback between terminal monitoring and microcirculation, comprising:

[0025] The first and third automatic control valves are closed, and the second automatic control valve is open for the distribution of water quality fluid sample flow in the test pipeline;

[0026] The various sensors of the monitoring device monitor parameters in the water quality fluid sample flow in the test pipeline in real time, including residual chlorine, dissolved oxygen, and / or turbidity.

[0027] The measuring device collects and monitors various data and uploads them to the server. The server analyzes whether each indicator or the rate of change of each indicator per unit time is within the set range. When the value of one or more indicators or the rate of change per unit time exceeds the set range, the server sends a signal to control the flushing microcirculation unit or the trigger-type purification unit to work and purify and regulate the water quality.

[0028] In one possible implementation, the server sends signals to control the operation of the flushing microcirculation unit or the trigger-type purification unit to purify and regulate the water quality, including:

[0029] Open the third automatic control valve and the booster pump located at the front end of the test pipeline to flush the test pipeline at the set water flow rate. When the flushing flow rate reaches the preset standard, stop flushing the test pipeline, close the third automatic control valve, and observe whether the water quality indicators such as residual chlorine, dissolved oxygen, and turbidity are within the set range. If the water quality meets the standard, continue to monitor the water quality online. If the water quality still does not meet the standard, close the second and third automatic control valves, open the first automatic control valve, and purify the water quality through the nanofiltration device.

[0030] Due to the adoption of the above technical solutions, this invention has the following characteristics: This invention can continuously and automatically monitor water quality and trigger microcirculation online. It can continuously monitor complementary monitoring indicators such as turbidity (particulate load), dissolved oxygen (microbial metabolic activity), and residual chlorine (disinfectant concentration) of the building water supply system, and generate results within a specified time interval. When the value of one or more indicators or the rate of change per unit time exceeds the set range, it will control the booster pump to release water to flush the microcirculation. If the water quality still cannot meet the standards after microcirculation, it will trigger the purification unit to purify the water quality through a nanofiltration device, ultimately achieving the optimization of water quality at the user end.

[0031] In summary, this invention can be widely applied to water quality detection and control. Attached Figure Description

[0037] Since most residents directly use tap water for cleaning and heating for drinking, without secondary treatment or end-user water quality monitoring, it is difficult to guarantee the quality of domestic water. This invention provides a real-time feedback water quality control system and method for end-user monitoring and microcirculation. The system includes: a test pipeline for distributing inflow water samples; a monitoring device installed on the test pipeline for monitoring residual chlorine, dissolved oxygen, and / or turbidity signals; a flushing microcirculation unit installed at the inlet of the test pipeline to increase pressure and flush the test pipeline, performing microcirculation; a trigger-activated purification unit installed on the test pipeline for purifying the water; and a measuring device for collecting data from the monitoring device and uploading it to a server. The server analyzes the monitored residual chlorine, dissolved oxygen, and / or turbidity signals and controls the booster pump or trigger-activated purification unit accordingly to purify and regulate the water quality. Therefore, this invention can continuously and automatically monitor water quality online and trigger microcirculation or purification units, ultimately achieving optimal water quality at the user end.

[0038] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art. The term "terminal" in this embodiment refers to the end of a drinking water pipe network system, which can be an entire building water system or a household water system, and is used as an example, but is not limited thereto.

[0039] Example 1: As Figure 1 As shown, the water quality control system for terminal monitoring and real-time feedback of microcirculation provided in this embodiment includes:

[0040] The supply device 1 is used to supply a corresponding inflow of water quality fluid sample stream from at least one of a plurality of inlet points selected from the water supply network (e.g., inlet water entering a household water system).

[0041] Test pipe 2 is used to connect and distribute the water quality fluid sample flow from supply device 1.

[0042] Monitoring device 3, installed on test pipeline 2, is used to monitor the residual chlorine signal, dissolved oxygen signal and / or turbidity signal of the incoming water quality fluid sample flow;

[0043] The flushing microcirculation unit 4 is set at the front end of the test pipe 1 and is used to flush the test pipe 1 and perform microcirculation flushing of the water quality.

[0044] The trigger-type purification unit 5 is installed at the inlet end of the test pipe 1 (for example, after the main water inlet of the building water supply system or the household water system) to purify the water quality.

[0045] The measuring device is used to collect monitoring data and upload it to the server. The server analyzes the collected residual chlorine signal, dissolved oxygen signal and / or turbidity signal. When one or more indicators such as turbidity, dissolved oxygen or residual chlorine exceed the set range or the rate of change per unit time exceeds the set range, the server controls the booster pump or trigger-type purification unit to work according to the measurement results to purify and regulate the water quality. The server can remotely operate each device and unit.

[0046] In a preferred embodiment of the present invention, the flushing microcirculation unit 4 may be a booster pump.

[0047] In a preferred embodiment of the present invention, the trigger-type purification unit 5 can be a nanofiltration device for purifying water quality.

[0048] In a preferred embodiment of the present invention, the monitoring device 3 includes a residual chlorine monitoring sensor, a dissolved oxygen monitoring sensor, and a turbidity monitoring sensor, wherein:

[0049] Residual chlorine monitoring sensor, used to monitor the residual chlorine signal of the incoming water quality fluid sample stream;

[0050] Dissolved oxygen monitoring sensor, used to monitor the dissolved oxygen signal of the incoming water quality fluid sample stream;

[0051] A turbidity monitoring sensor is used to monitor the turbidity signal of an incoming water quality fluid sample stream.

[0052] In a preferred embodiment of the present invention, such as Figure 1 As shown, the real-time feedback water quality control system also includes a first automatic control valve 6, a second automatic control valve 7, a third automatic control valve 8, a purification pipe 9, and a circulation pipe 10.

[0053] The test pipeline 2 is equipped with a purification pipeline 9 and a flow pipeline 10 connected in parallel.

[0054] The purification pipeline 9 is equipped with a first automatic control valve 6 and a nanofiltration device in sequence; the flow pipeline 10 is equipped with a second automatic control valve 7. When the nanofiltration device is started, the first automatic control valve 6 is opened; the second automatic control valve 7 is normally open and is closed when the nanofiltration device needs to be started; the third automatic control valve 8 is installed at the end of the test pipeline 1. When the water quality exceeds the standard and a booster pump is needed to flush the pipeline, it is opened for drainage. Each automatic control valve is connected to a PLC (not shown in the figure), and the valve can be remotely controlled to open and close through the PLC.

[0055] Furthermore, a flow monitoring sensor 11 is also installed on the test pipe 1 located at the front end of the third automatic control valve 8.

[0056] In a preferred embodiment of the present invention, the present invention further includes a power supply for supplying power to various electrical devices, which will not be described in detail here.

[0057] Example 2: The present invention also provides a control method for a water quality control system with real-time feedback between terminal monitoring and microcirculation, comprising:

[0058] S1, the first automatic control valve 6 and the third automatic control valve 8 are closed, and the second automatic control valve 7 is opened for the distribution of fluid sample flow in the test pipeline;

[0059] S2. The sensors of the monitoring device 3 monitor the parameters of the fluid sample flow in the test pipeline 1 in real time, including residual chlorine, dissolved oxygen and / or turbidity.

[0060] S3. The measuring device collects and monitors various data and uploads them to the server. The server analyzes whether each indicator or the rate of change of each indicator per unit time is within the set range. When the value of one or more indicators or the rate of change per unit time exceeds the set range, the server sends a signal to control the booster pump or the trigger-type purification unit to work and purify and regulate the water quality.

[0061] In this embodiment, the server sends signals to control the booster pump or nanofiltration device to operate, thereby purifying and regulating the water quality, including:

[0062] Open the third automatic control valve 8 and the booster pump located at the front end of the test pipeline 1 to flush the test pipeline 1 with the set water flow rate. When the flushing flow rate reaches the preset standard, stop flushing the test pipeline 1, close the third automatic control valve 8, and observe whether the water quality indicators such as residual chlorine, dissolved oxygen, and turbidity are within the set range. If the water quality meets the standard, continue to monitor the water quality online. If the water quality still does not meet the standard, close the second automatic control valve 7 and the third automatic control valve 8, open the first automatic control valve 6, and purify the water quality through the nanofiltration device.

[0063] The specific application of the present invention’s method for peripheral monitoring and real-time feedback of microcirculation in water quality regulation is described in detail below through specific embodiments.

[0064] A. Used for daily continuous monitoring of building water supply networks.

[0065] This embodiment describes the function of a terminal monitoring and microcirculation real-time feedback water quality control system for continuous and automatic online monitoring of water quality in a building water supply system. The specific implementation method is as follows:

[0066] like Figure 1As shown, the second automatic control valve 7 is opened to allow the inflow of fluid sample stream, while the first automatic control valve 6 and the third automatic control valve 8 are closed. The inflow of fluid sample stream (the supply line of the water to be analyzed) is monitored in real time by various sensors of the monitoring device 3, which monitor various parameters in the inflow of fluid sample stream, including residual chlorine, dissolved oxygen and / or turbidity.

[0067] The measuring device uploads the monitored data to the server. The server analyzes whether each indicator or its rate of change per unit time is within a set range. The normal range for each indicator or its rate of change per unit time can be set as needed and is not limited here. It can be set according to national standards or based on long-term monitoring data of the monitoring point. If all indicators are found to be normal, continuous online monitoring is maintained.

[0068] It should be noted that this embodiment is not limited to a specific number of sensors, branch lines, automatic control valves, etc. For illustrative purposes only, the protection of this invention is not limited; this is merely an example, and the invention is not limited thereto. Selection can be made according to actual needs.

[0069] B. Used for joint regulation of water quality by trigger-type microcirculation units and purification units in building water supply networks.

[0070] This embodiment describes the function of a terminal monitoring and real-time microcirculation feedback water quality control system for jointly controlling water quality in a building water supply system using a trigger-type microcirculation unit and a purification unit. The specific implementation method is as follows:

[0071] like Figure 1 As shown, the second automatic control valve 7 is opened to allow the inflow of fluid sample stream, while the first automatic control valve 6 and the third automatic control valve 8 are closed. The inflow of fluid sample stream (the supply line of the water to be analyzed) is monitored in real time by various sensors in the monitoring device 3, which acquire parameters such as residual chlorine, dissolved oxygen, and / or turbidity in the inflow fluid sample stream.

[0072] The measuring device uploads the monitoring data to the server, which analyzes whether each indicator or its rate of change per unit time is within the set range. The normal range for each indicator or its rate of change per unit time can be set as needed, either according to national standards or based on long-term monitoring data from the monitoring point; there are no restrictions.

[0073] When one or more indicators or their rate of change per unit time exceed a set range, the server sends a signal to trigger the micro-circulation unit to release water for purification. At this time, the second automatic control valve 7 and the third automatic control valve 8 located at the end of the pipeline open, the first automatic control valve 6 closes, and the booster pump located at the front end of the pipeline turns on, flushing the pipes at a flow rate greater than 1.5 m / s. This flushes away loose deposits in the building pipes, purifying the water. A flow sensor 11 is installed before the third automatic control valve 8 at the end of the pipeline. When the flushing flow rate is 3-5 times the total volume of water in the building pipes, the flushing stops. At this time, the second automatic control valve 7 opens, the third automatic control valve 8 closes, and the water quality indicators such as residual chlorine, dissolved oxygen, and turbidity are observed to see if they are within the set range. If the water quality meets the standards, the water quality is continuously monitored online. If the water quality still does not meet the standards, the second automatic control valve 7 and the third automatic control valve 8 are closed, the first automatic control valve 6 is opened, and the water entering the user end is purified by a nanofiltration device, ultimately achieving optimal water quality at the user end.

[0074] It should be noted that this embodiment is not limited to a specific number of sensors, branch lines, automatic valves, etc. For illustrative purposes only, the invention is not intended to be limited; this is merely an example, and the invention can be selected according to actual needs.
