[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] In an embodiment of the present invention: a tidal flow artificial wetland sewage discharge automatic regulation system includes a sewage concentration monitoring device, a water level monitoring device, a tidal flow pump regulating device and a municipal sewage discharge device that are interconnected; wherein the sewage concentration monitoring device and the water level monitoring device are installed and fixed in the artificial wetland, and are relatively fixed by using their own anchoring structures; the tidal flow pump regulating device is installed at the regulating pool; the municipal sewage discharge device is installed near the valve of the sewage treatment plant; the sewage concentration is monitored in real time by the sewage concentration monitoring device and the water level monitoring device, the water level is monitored and the water environment of the artificial wetland is dynamically monitored by the artificial wetland big data model; when the water environment deteriorates, the clean water source in the regulating pool is introduced into the artificial wetland through the tidal flow pump regulating device to dilute the sewage concentration; when the water environment improves and meets the standards, the sewage is discharged into the artificial wetland in a planned manner by controlling the municipal sewage discharge device, so that the artificial wetland can efficiently treat sewage.

[0038] Specifically, such as Figure 1 As shown: The sewage concentration monitoring device includes a solar photovoltaic panel A1, a signal antenna A2, a battery A3, a signal transmitter A4, a signal converter A5, a polyethylene float A6, a connecting ring A7, a power line A8, a data line A9, an anchor rope A10, a sewage concentration monitor A11 and an anchor hook A12; the anchor hook A12 is connected to the connecting ring A7 on the side surface of the polyethylene float A6 through the anchor rope A10, the solar photovoltaic panel A1 and the signal antenna A2 are arranged on the upper surface of the polyethylene float A6, and the battery A3, the signal transmitter A4 and the signal converter A5 are arranged inside the polyethylene float A6, and the battery A3 provides power to the sewage concentration monitor A11 through the power line A8. The sewage concentration monitor A11 is connected to the signal converter A5, the signal transmitter A4 and the signal antenna A2 via the data line A9 to provide working power. The sewage concentration monitor A11 can be connected to the signal converter A5, the signal transmitter A4 and the signal antenna A2 via the data line A9. The length of the anchor rope A10 can be adjusted to adapt the sewage concentration monitor to artificial wetlands of different depths. At the same time, the anchor rope A10 can be adapted to the ebb and flow of the artificial wetland by reserving a margin to ensure that the upper part of the sewage concentration monitor A11 will not be carried to the shore or other areas due to external factors such as wind during the floating process. After monitoring the sewage concentration, the sewage concentration monitor A11 transmits the monitored situation to the data analysis and processing module D26 of the urban sewage discharge device.

[0039] In the embodiment of the present invention, specifically, Figure 2As shown: the water level monitoring device includes a solar photovoltaic panel B14, a signal transmitter B15, a signal receiver B13, a battery B16, a signal conversion processor B17, a power line B18, a data transmission line B19, an electronic water level gauge B20 and an anchor rod B21; the lower part of the anchor rod B21 is fixed below the lowest water level line of the artificial wetland, and the anchor rod length is greater than the highest water level line of the artificial wetland. The electronic water level gauge B20 and the signal conversion processor B17 are installed on the upper part of the anchor rod B21. After the anchor rod B21 is fixed, it can ensure that the electronic water level gauge B20 does not deviate, thereby reducing the water level monitoring error; the signal conversion processor B17 is installed on the upper part of the anchor rod B21. A battery B16 is installed on the upper part of the device B17, and a solar photovoltaic panel B14, a signal transmitter B15 and a signal receiver B13 are provided on the upper part of the battery B16; the battery B16 provides working power to the electronic water level meter B20 through a power line B18, and the electronic water level meter B20 establishes a communication connection with the signal conversion processor B17, the signal transmitter B15 and the signal receiver B13 through a data transmission line B19; the device mainly measures the water level in the artificial wetland through the electronic water level meter B20, and transmits the data to the data analysis and processing module D26 of the urban sewage discharge device.

[0040] In the embodiment of the present invention, specifically, Figure 3 As shown: the tidal flow pump regulation device includes an inlet pump group C35, an outlet pump group C36, a water pump signal transmission line C32, a signal receiver C33, and a signal converter C34; the inlet pump group C35 and the outlet pump group C36 are respectively connected to the signal converter C34 through the water pump signal transmission line C32, and the signal receiver C33 is installed on the signal converter C34. The inlet pump group C35 and the outlet pump group C36 are adapted to artificial wetlands of different areas by configuring the number of water pumps.

[0041] In the embodiment of the present invention, specifically, Figure 4 As shown: the urban sewage discharge device includes a signal transmitter D23, a signal receiver D24, a second signal converter D22, a first signal converter D25, a data analysis and processing module D26, a data display screen D27, a flow meter signal transmission line D28, an electric valve signal transmission line D29, an electric valve D31 and a flow meter D30; the flow meter D30 is fixed on the electric valve D31 for monitoring the sewage discharge volume; the flow meter D30 and the electric valve D31 are respectively connected to the data display screen D27 through the flow meter signal transmission line D28 and the electric valve signal transmission line D29, the data display screen D27 is connected to the data analysis and processing module D26, the data analysis and processing module D26 is provided with a second signal converter D22 and a first signal converter D25, the first signal converter D25 is provided with a signal receiver D24, and the second signal converter D22 is provided with a signal transmitter D23.

[0042] Among them, solar photovoltaic panels A1, solar photovoltaic panels B14 and batteries A3 and B16 can allow the sewage concentration monitoring device and the water level monitoring device to operate independently, avoiding the trouble of needing integrated wiring. At the same time, the batteries can ensure that the two devices can continue to operate for a certain period in a dark environment such as cloudy days.

[0043] In the above embodiment, after monitoring the sewage concentration, the sewage concentration monitor A11 in the sewage concentration monitoring device converts the monitored data into electromagnetic waves through the signal converter A5, and transmits the data to the signal receiver D24 of the urban sewage discharge device through the signal transmitter A4 and the signal antenna A2; the water level monitoring device monitors the water level elevation in the artificial wetland in real time through the electronic water level meter B20, and transmits the measured data to the signal conversion processor B17 through the data transmission line B19, converts the measured data into electromagnetic waves, and transmits the signal to the signal receiver D24 of the urban sewage discharge device through the signal transmitter B15. After receiving the signal, the signal receiver D24 of the urban sewage discharge device converts the electromagnetic wave into corresponding sewage concentration data and water level elevation through the first signal converter D25. Combined with the large-volume model of the artificial wetland water storage capacity, the data is analyzed and processed by the data analysis and processing module D26. When the sewage concentration does not reach the carrying limit of the ecological wetland, the electric valve D31 continues to open and the sewage is discharged into the artificial wetland in an orderly manner; when the concentration analyzed by the data analysis and processing module D26 is about to reach the carrying limit of the ecological wetland, the data analysis and processing module D26 transmits the valve closing signal to the electric valve D31 through the electric valve signal transmission line D29, the electric valve D31 closes, and the sewage stops flowing into the artificial wetland.

[0044] In the above embodiment, when the sewage artificial wetland is disturbed by temperature, light, wind speed and other factors, the sewage treatment capacity decreases. After comprehensively analyzing the data, the urban sewage discharge device sends a valve opening or closing signal. If the tidal flow regulating pool needs to intervene, the urban sewage discharge device converts the valve opening or closing instruction obtained by the data analysis and processing module D26 into an electromagnetic wave by the second signal converter D22, and then transmits it to the tidal flow pump regulating device by the signal transmitter D23. The tidal flow pump regulating device converts the electromagnetic wave into the opening or closing of the water inlet pump group C35 and the water outlet pump group C36 through the signal receiver C33 and the signal converter C34 to adjust the sewage concentration and water level in the artificial wetland, as well as the ebb and flow of the tidal flow artificial wetland.

[0045] In the above embodiment, the data analysis and processing module D26 in the urban sewage discharge device sets the values ​​of C1 (the concentration of elements such as N, P, and S in the water body when the sewage concentration reaches the level of general surface water) and C2 (the concentration of elements such as N, P, and S in the water body when the sewage concentration reaches the level of ecological collapse, which is likely to cause eutrophication) within the normal operating range of the artificial wetland through the data display screen D27. When the urban sewage discharge device receives data transmitted from the sewage concentration monitoring device and the water level monitoring device, it uses the data analysis and processing module D26 of the device in combination with the large-volume model of the artificial wetland to perform calculations. Specifically:

[0046] When the sewage concentration C3 reported by the sewage concentration monitor A11 is higher than the set sewage concentration C2, that is, C3>C2, the sewage discharge device controls the electric valve D31 to close the valve and uses the data analysis and processing module D26 to transmit a signal to the tidal flow pump regulating device. The tidal flow pump regulating device starts the water inlet pump group C35, introducing the clean water source in the regulating pool into the artificial wetland, and adjusting the sewage concentration C3 to less than the set concentration C2.

[0047] When the sewage concentration C3 reported by the sewage concentration monitor A11 is lower than the set sewage concentration C2 or C1, the data analysis and processing module D26 transmits a signal to the tidal flow pump regulating device, which turns on the outlet pump group C36 to introduce the relatively clean water source in the artificial wetland into the regulating pool for standby use. After reaching the specified water level, the pump stops operating and the electric valve D31 is opened to discharge the sewage into the artificial wetland.

[0048] See also Figure 5-7 In order to further better explain the embodiments of the present invention, a method for using a tidal flow artificial wetland sewage discharge automatic regulation system is also provided, comprising the following steps:

[0049] S1: Install the sewage concentration monitoring device and water level monitoring device in the artificial wetland and fix them;

[0051] S3: Link the sewage concentration monitoring device, water level monitoring device, tidal flow pump regulating device, and urban sewage discharge device in a small scale to ensure the normal operation of the tidal flow artificial wetland sewage discharge automatic regulating system;

[0052] S4: The data analysis and processing module D26 in the urban sewage discharge device sets the values ​​of C1 and C2 within the normal working range of the artificial wetland through the data display screen D27, where C1 is the concentration of N, P, and S elements in the water body when the sewage concentration reaches the level of general surface water, and C2 is the concentration of N, P, and S elements in the water body when the sewage concentration reaches the level of ecological collapse and is likely to cause eutrophication of the water body;

[0053] S5: Increase the number of water pumps in the inlet pump group C35 and the outlet pump group C36 to meet the speed of the artificial wetland's ebb and flow;

[0054] S6: By adjusting the length of the anchor rod B21 in the water level monitoring device, it is used to meet the requirements of wetland water level monitoring at different depths;

[0055] S7: By adding a sewage concentration monitoring device and then conducting sample statistical analysis, the sewage concentration in the artificial wetland can be obtained more accurately.

[0056] In summary: The present invention provides an automatic regulation system for sewage discharge from a tidal flow artificial wetland and a method for use. Through a sewage concentration monitoring device, a water level monitoring device and a large digital model of an artificial wetland, the sewage concentration and water storage capacity in the artificial wetland are monitored and controlled in real time. Under the interaction of various devices, the sewage discharge is automatically adjusted. Through the tidal flow regulation pool and the tidal flow water pump regulation device, a system that can self-regulate sewage discharge is formed, which effectively enhances the sewage treatment capacity and ecological environment self-regulation capacity of the tidal flow artificial wetland, and reduces the ecological maintenance cost of the tidal flow artificial wetland.
