Detailed Description
Various embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Here, it is to be noted that, in the drawings, the same reference numerals are given to constituent parts having substantially the same or similar structures and functions, and repeated description thereof will be omitted. The term "sequentially comprising A, B, etc" merely indicates the order of the included elements A, B, etc. and does not exclude the possibility of including other elements between a and B and/or between B and B.
The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of the respective portions and the mutual relationships thereof.
Hereinafter, referring to fig. 1 and 2, a preferred embodiment according to the present invention will be described in detail.
Fig. 1 shows a block diagram of a rain sewage treatment system according to the present invention. The rainwater and sewage treatment system includes a monitoring device 1 configured to monitor a liquid level and a liquid level variation amount of a regulation tank, and generate a liquid level signal and a liquid level variation signal. The control device 2 is communicatively connected to the monitoring device and is configured to receive the liquid level signal and the liquid level variation signal from the monitoring device. The coagulation sedimentation tank unit 3 is communicatively connected to the control device, and communicates with the regulation tank to receive the rainwater water from the regulation tank, and includes a plurality of coagulation sedimentation tanks.
In this example, the monitoring device generates a rainfall signal and a catchment canal liquid level signal by monitoring the rainfall state and the liquid level of the catchment canal, respectively, the catchment canal being used to collect rain water and convey the rain water to the storage tank. The control device predicts the liquid level variation of the regulation and storage tank by analyzing the rainfall signal and the water collecting pipe and canal liquid level signal, thereby obtaining the liquid level variation signal. However, it will be appreciated by those skilled in the art that the monitoring device can also directly obtain the liquid change signal by monitoring the amount of change in the liquid level in the storage tank, without monitoring the rainfall state and monitoring the liquid level in the catchment canal.
The control device is configured to compare the liquid level signal to a predetermined liquid level threshold upon receiving the liquid level signal and the liquid level change signal. And under the condition that the liquid level signal is greater than a preset liquid level threshold value, the control device predicts a water inflow peak value based on the liquid level change signal, calculates the ratio of the predicted water inflow peak value to a preset design peak value, calculates the number of the coagulation sedimentation tanks to be started based on the calculated ratio, and sends a starting signal to the coagulation sedimentation tank unit to start the coagulation sedimentation tanks in the number.
Fig. 2 shows an example of a coagulation sedimentation tank unit. In this example, the coagulating sedimentation basin unit comprises 6 coagulating sedimentation basins a-F, and the 6 coagulating sedimentation basins are divided into three groups of 2 coagulating sedimentation basins each. It will be appreciated by those skilled in the art that any number of coagulative precipitation tanks may be included.
As described above, in the case where the liquid level signal is greater than the predetermined liquid level threshold value, the control device predicts the inflow peak value based on the liquid level variation signal, and calculates the ratio of the predicted inflow peak value to the predetermined design peak value. When the calculated ratio is within a certain predetermined ratio range of a plurality of predetermined ratio ranges, the control device obtains the number of the coagulation sedimentation tanks to be started, and sends starting information to the number of the coagulation sedimentation tanks. For example, when the ratio of the predicted inlet water flow peak value to the preset design peak value is between 0 and 33 percent, the control device sends a starting signal to the first group of coagulating sedimentation tanks A and B.
The interval lengths of the plurality of predetermined ratio ranges are determined based on the following formula: and L is 1 x 100%/m, wherein L is the interval length, and m is the total number of the coagulation sedimentation tank. For example, when there are 6 coagulating sedimentation tanks and every 2 coagulating sedimentation tanks are used as a group, the interval length L of the corresponding predetermined ratio range is 2 × 100%/6 — 33% for each group of coagulating sedimentation tanks.
During the start-up of this number of coagulation sedimentation tanks, for example during the start-up of the first set of coagulation sedimentation tanks a and B, the reject produced water produced by the coagulation sedimentation tanks a and B may be discharged to the remaining coagulation sedimentation tanks C-F of the coagulation sedimentation tank unit, preferably to the second set of coagulation sedimentation tanks C and D. After the first group of coagulating sedimentation tanks A and B are started, the coagulating sedimentation tanks A and B are normally operated, and qualified effluent enters a water producing channel.
The control means issues a start signal to the second set of coagulation sedimentation tanks C and D when the calculated ratio is in another one of the predetermined ratio ranges, for example when the calculated ratio is in the range of 34-66%.
Similarly, during start-up of the second set of coagulative precipitation tanks C and D, the off-spec produced water produced by the coagulative precipitation tanks C and D may be discharged to the coagulative precipitation tanks E and F of the coagulative precipitation tank unit. After the second group of coagulating sedimentation tanks C and D are started, the coagulating sedimentation tanks C and D are normally operated, and qualified effluent enters a water producing channel.
The control means sends a start signal to the third set of coagulation sedimentation tanks E and F when the calculated ratio is in a further predetermined ratio range of the plurality of predetermined ratio ranges, for example when the calculated ratio is 67-100%.
During start-up of the third set of coagulative precipitation tanks E and F, the off-spec produced water produced by the coagulative precipitation tanks E and F may be returned to the coagulative precipitation tanks E and F. And after the third group of coagulating sedimentation tanks E and F are started, the coagulating sedimentation tanks E and F are normally operated, and qualified effluent enters a water producing channel.
As shown in fig. 2, the coagulation sedimentation tank unit 3 comprises a water inlet pipe 31, and rain sewage flows into an inlet channel 32 of the coagulation sedimentation tank unit through the water inlet pipe 31; a return channel 33, each coagulation sedimentation tank of the coagulation sedimentation tank unit is communicated with the return channel 33 through a first automatic gate 34; the main water outlet channel 35, the production channel 37 of each coagulation sedimentation tank of the coagulation sedimentation tank unit are communicated with the main water outlet channel 35 through a second automatic gate plate 36. In this example, the first set of coagulative precipitation tanks a and B share a production canal 37, the second set of coagulative precipitation tanks C and D share a production canal 37, and the third set of coagulative precipitation tanks E and F share a production canal 37, but it will be appreciated that each coagulative precipitation tank may have a respective production canal that communicates with the main water outlet canal.

Those skilled in the art will appreciate that the location of the inlet channel 32 and return channel 33 is not limited as long as the functions described herein are achieved.
In such a case, during the start-up of the first set of coagulating sedimentation tanks a and B, the second automatic gate plates 36 corresponding to the coagulating sedimentation tanks a and B are closed, while the first automatic gate plates 34 corresponding to the coagulating sedimentation tanks a and B are opened, so that the reject produced water produced by the coagulating sedimentation tanks a and B is flowed to the coagulating sedimentation tanks C and D of the coagulating sedimentation tank unit via the return channel 33 by the return pump (not shown).
After the start-up of the coagulation sedimentation tanks a and B is completed, the first automatic gate plates 34 corresponding to the coagulation sedimentation tanks a and B are closed, and the second automatic gate plates 36 corresponding to the coagulation sedimentation tanks a and B are opened, so that the qualified produced water produced by the coagulation sedimentation tanks a and B flows into the production channel and into the main production channel.
Similarly, the above operations can also be performed during the start-up of the second set of coagulating sedimentation tanks C and D, and are not described in detail herein.
During the start-up of the third set of coagulation sedimentation tanks E and F, the second automatic shutter 36 corresponding to the coagulation sedimentation tanks E and F is closed, and the first automatic shutter 34 corresponding to the coagulation sedimentation tanks E and F is opened, so that the reject produced water produced by the coagulation sedimentation tanks E and F is returned to the coagulation sedimentation tanks E and F via the return channel 33 by a return pump (not shown).
