The utility model discloses a rainwater regulation pond theory of operation as follows:
1. in sunny days, the rainwater storage tank is not opened, and the first electric gate 4 and the second electric gate 5 are in a closed state.
2. At the initial stage of rainfall, the first water quality instrument 2 in the inlet channel 3 detects that the quality of the incoming water of the inlet pipe 1 is the initial stage runoff water quality (dirty rainwater), and the first electric gate 4 of operating system control is opened, and the initial stage rainwater flows into the first rain receiving chamber 7 of the regulation pond along the first electric gate 4 at this moment.
3. Later stage in the rainfall, first quality of water appearance 2 detects inlet tube 1 and comes water quality of water and be later stage runoff quality of water (comparatively clean rainwater), and operating system control first electric gate 4 closes, and second electric gate 5 opens. The middle and later stage rainwater flows into the passing chamber 13 of the regulation and storage tank along the second electric gate 5. The water level rises to the height of the water outlet overflow weir 16 through the chamber 13, then overflows and is discharged to a downstream rainwater pipeline along a water outlet pipe 17 in the water outlet overflow weir 16.
4. In extreme rainstorm conditions, the inlet pipe 1 carries a peak flow. At this time, the inflow rate of water flowing into the passing chamber 13 along the second electric lock 5 is larger than the outflow rate of water flowing over the overflow weir 16, and when the water level of the passing chamber 13 rises and reaches the height of the first overflow port 19, rainwater in the passing chamber 13 overflows from the first overflow port 19 to the stage I peak clipping receiving chamber 18. When the third liquid level meter 20 installed in the stage I peak clipping receiving chamber 18 detects that the water level reaches the pump starting water level, the first pressure pump 28 and the first water inlet valve 26 in the rainwater recycling system 25 are controlled to be opened, rainwater is conveyed to the rainwater treatment device 30, and after being filtered and disinfected, the rainwater reaches the quality standard of the reuse water of miscellaneous water and is conveyed to the stage II peak clipping receiving chamber 23 through the third pressure pump 31 and the third water inlet valve 32 to be stored. When the third liquid level meter 20 detects that the water level reaches the pump stop water level, the first booster pump 28 and the first water inlet valve 26 are controlled to be closed, and if the water level rises to the height of the second overflow port 21, rainwater in the stage I peak clipping receiving chamber 18 overflows from the second overflow port 21 to the stage II peak clipping receiving chamber 23. The fourth liquid level meter 22 arranged in the II-stage peak clipping receiving chamber 23 monitors the water level to display the quantity of the reuse water stored in the regulating reservoir. After the peak flow of the inlet pipe 1 disappears, the stage I peak clipping receiving chamber 18 does not feed any more since the inlet flow through the chamber 13 is the same as the outlet flow overflowing along the overflow weir 16.
5. After the rainfall is finished, the first rain receiving chamber 7 is emptied. The operating system controls the first submersible sewage pump 6 to be started, and rainwater in the initial rain receiving chamber 7 is pumped and discharged to a sewage treatment plant. When the first liquid level meter 8 monitors that the water level drops to the pump stop water level, the first submersible sewage pump 6 is controlled to be closed, and the emptying of the primary rain receiving chamber 7 is finished.
6 after the rainfall is over, the through chamber 13 is emptied. After the precipitation through the rain interface in the chamber 13 is finished, emptying through the chamber 13 is started. A certain height above the turbid liquid level detected by the particle settling test is used as a set water level, and the turbidity of the set water level is monitored by the second water quality instrument 12. When the turbidity does not reach the standard, no water is drained through the chamber 13. When the turbidity reached the standard, drainage through the chamber 13 started. Firstly, the rainwater pump 11 is controlled to be started, and clear water above a set water level is discharged into a downstream rainwater pipeline. When the second liquid level meter 14 detects that the water level drops below the set water level, the rainwater pump 11 is controlled to be turned off; the second submersible sewage pump 10 is then turned on, and the muddy water below the set water level is pumped out to a sewage treatment plant. When the water level drops to the stop pump level, the second submersible sewage pump 10 is turned off and emptying through chamber 13 is complete.
7. And according to the weather forecast, early warning is carried out on the rainstorm weather. If rainstorm warning exists in 24 hours in the future, the control system judges that the II-level peak clipping receiving chamber 23 is emptied to reserve a peak clipping space. And controlling the recycled water lift pump 35 and the second water outlet valve 36 to be opened, and pumping and discharging the clean water stored in the II-stage peak clipping receiving chamber 23 to a downstream rainwater pipeline. If no rainstorm warning exists in 24 hours in the future, the control system judges that the II-level peak clipping receiving chamber 23 stores recycled water to ensure the comprehensive utilization of rainwater. When the rainwater is used, the control reuse water lift pump 35 and the first water outlet valve 34 are opened, the clear water stored in the II-level peak clipping receiving chamber 23 is pumped and discharged to a reuse pipeline, and the reuse rainwater is used for road watering, greening irrigation, municipal fire protection and groundwater replenishment.
8. When no clear water is stored in the II-stage peak clipping receiving chamber 23 and no rainfall occurs for a long time, the fourth water inlet valve 33 is opened, and water is supplemented to the II-stage peak clipping receiving chamber 23 through a municipal water supply pipe network. When the I-stage peak clipping receiving chamber 18 does not store rainwater, the second pressure pump 29 and the second water inlet valve 27 are controlled to be opened, and clear water passing through the upper layer in the chamber 13 is conveyed to the rainwater treatment device 30 and conveyed to the II-stage peak clipping receiving chamber 23 for storage after treatment.
The above embodiments are only used for the design idea and features of the present invention, and the purpose is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, and the protection scope of the present invention is not limited to the above embodiments.
