Description

Technical Field

[0001] The invention belongs to the technical field of municipal drainage, and in particular relates to an adjustable storage device and apparatus with interception and buffer facilities. Background Art

[0002] The municipal drainage system in a city is mainly divided into a combined drainage system and a separate drainage system. The earliest combined drainage system mixed sewage, industrial wastewater and rainwater in the same pipe and directly discharged it into the nearby water body without any treatment, which easily caused serious pollution to the receiving water body. The separate drainage system is a device that discharges domestic sewage, industrial wastewater and rainwater in two or more independent pipes.

[0003] At present, in the existing municipal drainage technology, most combined sewer communities have the following problems:

[0004] (1) On rainy days, rainwater is divided into initial rain and mid- and late-stage rain according to the duration method, water quality method, or liquid level method. The discharge method for initial rain is generally to divert the initial rain directly to the municipal sewage pipe and reuse it after treatment in the sewage treatment plant. However, the transportation capacity of the sewage pipe is limited and it cannot accommodate a large amount of mixed water of sewage and rainwater. If the sewage pipe is to be modified, it will inevitably cause too high a cost. The mixed water of sewage and initial rain is sent to the sewage treatment plant for treatment due to its large amount, which will also cause insufficient capacity of the sewage treatment plant or waste of treatment resources. In addition, on sunny days, since the initial rain has been treated and discharged on rainy days, the water treatment and discharge volume only involves domestic sewage. In this way, due to the insufficient water treatment discharge volume during long-term sunny days, it is very easy to cause a situation where there is no water replenishment along the river channel, resulting in river drying up.

[0005] (2) Since the internal pipe system of the combined sewer community does not separate the discharge of sewage and rainwater, on the one hand, on rainy days, a large amount of sewage is mixed in the rainwater flowing out of the combined branch pipe. If this part of sewage is transported to the municipal combined pipe at this time, it is very easy to cause the natural water body connected to the municipal combined pipe to be polluted; on the other hand, there is continuous sewage and rainwater flowing into the combined branch pipe. At this time, the sewage is diluted by the rainwater, but the concentration of pollutants in it is still relatively high. Therefore, the middle and late rainwater flowing out of the combined branch pipe is also sewage. If the middle and late rainwater flows into the municipal combined pipe, it will still cause natural water bodies to be polluted. At the same time, since the amount of middle and late rainwater is large and the capacity of the municipal combined pipe is limited, it cannot accommodate middle and late rainwater and sewage. If the combined branch pipe is renovated, it will inevitably result in too high a cost. If the amount of middle and late rainwater mixed with domestic sewage is sent to the sewage treatment plant for treatment, it will also cause insufficient capacity of the sewage treatment plant or waste of treatment resources.

[0006] It can be seen that in the existing municipal drainage technology, the treatment and discharge of rainwater in combined sewer communities on rainy days do not achieve rainwater and sewage separation, resulting in great treatment pressure on the treatment facilities, overload operation of the treatment facilities, and reduced service life of the treatment facilities. In addition, on sunny days, insufficient water treatment discharge can easily lead to a lack of water replenishment along the river, resulting in the technical defect of river drying up. Summary of the invention

[0007] The technical problem to be solved by the present invention is that on rainy days, the treatment pressure of the sewage treatment plant is very high and it operates at overload, the service life of the treatment facilities is extremely short and it is very easy to waste resources. At the same time, it also increases the transportation pressure and transportation intensity of the sewage pipe, and the transformation of the sewage pipe is bound to increase the cost, and there is a technical defect that the river is very likely to dry up on sunny days.

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the scope of protection of the present invention; the "and / or" keyword involved in this implementation represents both and, or. In other words, A and / or B mentioned in the embodiments of the present invention represent both A and B, and A or B, and describe the three states of A and B. For example, A and / or B means: only A is included but not B; only B is included but not A; both A and B are included.

[0063] At the same time, in the embodiments of the present invention, when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected or communicated" with another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the present invention.

[0064] It should be noted that, in order to explain the present invention in more detail so that those skilled in the art can understand the present invention more clearly and understandably, and further support the technical problems to be solved by the present invention and the corresponding technical effects that can be achieved, before introducing the present invention, the following explanations are given for the terminology involved:

[0065] A combined branch pipe is a pipe used in the unit area pipe to transport rainwater, sewage, or a mixture of rainwater and sewage; a sewage branch pipe is a pipe used in the unit area pipe to transport sewage; a municipal combined pipe is a pipe used in the municipal pipe to transport rainwater, sewage, or a mixture of rainwater and sewage.

[0066] Those skilled in the art can understand that the above-mentioned "rainwater", "sewage" and "mixed water" are not limitations on the functions of "branch pipes" or "pipes", but are only used to distinguish them. In other words, the combined branch pipe, sewage branch pipe and municipal combined pipe can all use the same pipe, or different pipes, or pipes that are partially the same and partially different. The present invention does not limit this. As long as the pipe can realize liquid transportation, it is applicable to the present invention and is within the protection scope of the present invention.

[0067] According to whether rainfall occurs, the period involved in the present invention can be divided into rainfall period and non-rainfall period, wherein the rainfall period refers to the period when rainfall occurs, which can be understood as a rainy day; the non-rainfall period is a period opposite to the rainfall period, which refers to the period when no rainfall occurs, which can be understood as a sunny day. Alternatively, according to the amount of rainfall, the period involved in the present invention can also be divided into rainfall period and non-rainfall period, wherein the rainfall period refers to the period when the rainfall reaches a certain rainfall threshold, which can be understood as a period when the rainfall is slightly heavier; the non-rainfall period is a period opposite to the rainfall period, which refers to the period when the rainfall is less than the rainfall threshold, which can be understood as a period when there is no rainfall or the rainfall is relatively small.

[0068] In the present invention, it is not limited to which of the above methods is used to determine the rainfall period and the non-rainfall period, and it can be selected and determined according to actual operation requirements; in other words, any of the above methods for determining the rainfall period and the non-rainfall period is applicable to the present invention. As for how to judge whether rainfall occurs and how to judge whether the rainfall reaches a certain rainfall threshold, the judgment method of the prior art can be adopted. The present invention no longer limits the judgment method for whether rainfall occurs and the judgment method for whether rainfall reaches a certain rainfall threshold. As long as the judgment method can achieve the judgment result of whether rainfall occurs or whether rainfall reaches a certain rainfall threshold, it is applicable to the present invention.

[0069] Furthermore, with respect to the rainfall period, the rain can be divided into initial rain and middle and late rain, and the division method can adopt the time method, water quality method or liquid level method in the prior art. For example, when the time method is adopted, the rain corresponding to the rainfall period is the initial rain, and the rain corresponding to the middle and late rainfall period is the middle and late rain; for example, when the water quality method is adopted, when the rainwater concentration is higher than a certain concentration threshold, the rainwater is the initial rain, and when the rainwater concentration is lower than a certain concentration threshold, the rainwater is the middle and late rain; for example, when the liquid level method is adopted, when the rainwater liquid level is lower than a certain liquid level threshold, the rainwater is the initial rain, and when the rainwater liquid level is higher than a certain liquid level threshold, the rainwater is the middle and late rain.

[0070] Similarly, there is no limitation on which of the above methods is used to determine the initial rain or mid-to-late rain, and it can be determined according to actual operational requirements; in other words, any of the above methods for determining the initial rain or mid-to-late rain is applicable to the present invention.

[0071] Of course, those skilled in the art should understand that since certain errors are allowed in the discharge of rainwater and / or sewage during actual operations, there may be certain errors in the specific division of each period. For example, there may be inaccurate division nodes between initial rain and mid- and late-stage rain, resulting in mid- and late-stage rain mixed with initial rain, or a small amount of sewage mixed with initial rain / mid- and late-stage rain, etc. The operational impact caused by this error does not affect the implementation effect of the entire technical solution of the present invention and can be ignored, and should not be considered to be beyond the protection scope of the present invention.

[0072] Embodiment 1

[0073] Please refer to Figure 1 , which is a schematic diagram of the overall structure of an adjustable storage device with interception and buffer facilities provided in Example 1 of the present invention. The adjustable storage device with interception and buffer facilities is applied to a drainage system, and the drainage system includes: a combined branch pipe 1, a sewage branch pipe 2, a rainwater inlet 3, a municipal combined pipe 6, etc.; the adjustable storage device specifically includes a first diversion facility 4, an initial rain storage facility 5, a second diversion facility 7, an online treatment facility 11, a sewage treatment facility 12 and an interception facility 13.

[0074] Among them, the combined branch pipe 1, sewage branch pipe 2, and rainwater inlet 3 in the drainage system can all be set in the unit area, which is an area where sewage and rainwater need to be treated, and can be a residential area, school, administrative area, etc. Of course, in the actual setting process, in order to connect with the municipal pipeline, some branches extend outside the unit area or to the municipal road, which is also applicable to the present invention, and the present invention does not limit this. The combined branch pipe 1 is connected to the rainwater inlet 3 for transporting rainwater, so that the initial rain, middle and late rain in the rainfall period are transported after being merged into the combined branch pipe 1 through the rainwater inlet 3. It can be understood that the number of rainwater inlets 3 can be multiple, and the distribution positions of multiple rainwater inlets 3 in the unit area can be arbitrary. In the actual process, they can be reasonably set according to the actual rainfall direction, and the present invention does not limit this. The sewage branch pipe 2 is connected to the municipal combined pipe 10, so that the sewage in the unit area is first collected in the sewage branch pipe 2, and then the sewage branch pipe 2 transports the sewage to the combined branch pipe 1; the municipal combined pipe 10 can be connected to the second diversion facility 7, and connected to the sewage treatment facility 12 (such as a sewage treatment plant) through the second diversion facility 7, and the sewage is discharged after being treated by the sewage treatment facility 12, and can also be connected to the online treatment facility 11 (such as a biological filter tank) through the second diversion facility 7, and rainwater or a mixture of rainwater and sewage is treated by the online treatment facility 11 and discharged.

[0075] Among them, the embodiment of the present invention is provided with an interception facility 13 between the sewage branch pipe 2 and the municipal combined pipe 6, so as to intercept the sewage in the sewage branch pipe 2 through the interception facility 13, for example, during the rainy period, intercept the sewage so that it does not flow into the combined branch pipe 1, thereby realizing the separation of rainwater and sewage during the rainy period, and during the non-rainy period, release the sewage so that it flows into the combined branch pipe 1. At the same time, the buffer facility 14 is connected to the interception facility 13, so that the sewage during the interception period is intercepted and stored in the buffer facility 14 through the interception facility 13, thereby achieving that even during the interception process during the rainy period, the normal discharge of sewage in the unit area is not affected.

[0076] In addition, the present invention is provided with a first diversion facility 4 and an initial rain storage facility 5 at the downstream position of the combined branch pipe 1, the first diversion facility 4 is respectively connected to the combined branch pipe 1 and the municipal combined pipe 6, and the initial rain storage facility 5 is connected to the first diversion facility 4. It can be understood that the first diversion facility 4 is provided with a connection structure of at least one water inlet and two water outlets, that is, the first diversion facility 4 is connected to the combined branch pipe 1 through the water inlet, and is respectively connected to the initial rain storage facility 5 and the municipal combined pipe 6 through the two water outlets.

[0077] In this way, the initial rain in the rainfall period in the combined branch pipe 1 can be diverted through the first diversion facility 4, and the initial rain can be stored after being diverted by the first diversion facility 4. Of course, the start time of the interception facility 13 intercepting the sewage in the sewage branch pipe 2 and the start time of the first diversion facility 4 diverting the initial rain in the rainfall period in the combined branch pipe 1 can be the same time, that is, the two are carried out at the same time, or the interception facility 13 can intercept the sewage branch pipe 2 first, and the first diversion facility 4 can divert the initial rain in the rainfall period in the combined branch pipe 1 later. The present invention does not limit the control sequence, as long as it can The control methods of intercepting the sewage in the sewage branch pipe 2 by the interception facility 13 during the rainy period and diverting the initial rain in the combined branch pipe 1 during the rainy period by the first diversion facility 4 are applicable to the present invention and are also within the protection scope of the present invention, thereby effectively avoiding the defects of excessive treatment pressure and waste of resources caused by direct delivery of the initial rain to the municipal combined pipe and then to the sewage treatment facility by the municipal combined pipe, effectively reducing the treatment pressure of the sewage treatment facility during the rainy period, alleviating its overloaded working state, and also increasing the service life of the sewage treatment facility, and reducing the cost of sewage pipe reconstruction. In addition, in the non-rainy period, the stored initial rain is diverted to the online treatment facility 11 or the sewage treatment facility 12 for treatment through the first diversion facility 4 and the second diversion facility 7 in turn, and then flows into the natural water body or the downstream pipeline, effectively avoiding the technical defects of river drying caused by only treating and discharging sewage during the non-rainy period, and effectively replenishing the river water.

[0078] As an implementation method for realizing the diversion action of the first diversion facility 4, the embodiment of the present invention may include a first hydraulic switch and a second hydraulic switch. The first hydraulic switch is arranged at the outlet of the first diversion facility 4 in the direction of the municipal combined pipe 6; the second hydraulic switch is arranged at the outlet of the first diversion facility 4 in the direction of the initial rain storage facility 5. By controlling the first hydraulic switch to be closed and the second hydraulic switch to be opened during the rainy period, the initial rain in the combined branch pipe 1 is diverted to the initial rain storage facility 5 through the first diversion facility 4 for storage, and for the middle and late rain, by controlling the first hydraulic switch to be opened and the second hydraulic switch to be closed, the middle and late rain in the combined branch pipe 1 is diverted to the online treatment facility 11 through the first diversion facility 4 and the second diversion facility 7 in turn for treatment, thereby realizing the storage of the initial rain during the rainy period, reducing the processing pressure of the treatment facility, and avoiding waste of resources, and also realizing the replenishment of the water level in the natural water body during the non-rainy period.

[0079] As another implementation method for realizing the diversion action of the first diversion facility 4, the embodiment of the present invention may also include a first pump; the first pump is arranged in the initial rain regulating and storing facility 5 to pump the initial rain from the initial rain regulating and storing facility 5 to the municipal combined pipe 6 or the second diversion facility 7. Also in this implementation method, the embodiment of the present invention further includes a first hydraulic switch arranged at the water outlet of the first diversion facility 4 in the direction of the municipal combined pipe 6, and a second hydraulic switch arranged at the water outlet of the first diversion facility 4 in the direction of the initial rain regulating and storing facility 5. Specifically, during the rainfall period, the first hydraulic switch is controlled to be closed and the second hydraulic switch is controlled to be opened, so that the initial rain in the combined branch pipe 1 is diverted to the initial rain storage facility 5 through the first diversion facility 4 for storage. For the middle and late rain, by controlling the first hydraulic switch to be opened and the second hydraulic switch to be closed, the middle and late rain in the combined branch pipe 1 is diverted to the online treatment facility 11 through the first diversion facility 4, the municipal combined pipe 6, and the second diversion facility 7 in sequence for treatment, thereby realizing the storage of the initial rain during the rainfall period, reducing the treatment pressure of the treatment facilities, and also avoiding waste of resources. During the non-rainfall period, the first hydraulic switch is controlled to be turned on, and the second hydraulic switch is controlled to be turned on. At this time, the initial rain stored in the initial rain storage facility 5 is diverted to the online treatment facility 11 through the first diversion facility 4, the municipal combined pipe 6, and the second diversion facility 7 in sequence, and then discharged to the natural water body after treatment, thereby replenishing the water level in the natural water body during the non-rainfall period. When the drainage demand is very large, the first pump is controlled to synchronously pump the initial rain in the initial rain storage facility 5 back to the second diversion facility 7 or the online treatment facility 11, so as to solve the situation where the current water supply cannot be met by only turning on the second hydraulic switch, or the first hydraulic switch can also be turned off when the initial rain in the initial rain storage facility 5 is pumped back by the first pump.

[0080] Those skilled in the art will understand that, as to which of the above-mentioned implementation modes is used to transport the initial rain in the initial rain storage facility 5 to the second diversion facility 7 or the online processing facility 11, the control can be selected according to actual operational needs; in other words, the present invention does not specifically limit the method of transporting the initial rain in the initial rain storage facility 5, and the above-mentioned two transportation methods, as well as similar transportation methods in the prior art, are all applicable to the present invention as long as they can achieve the technical effect of remotely transporting the initial rain in the initial rain storage facility 5 to the second diversion facility 7 or the online processing facility 11, and are also within the protection scope of the present invention.

[0081] Furthermore, with regard to the sewage entering the combined branch pipe 1 from the sewage branch pipe 2, since it may exist both during rainy periods and non-rainy periods, in the two implementations of the diversion action of the first diversion facility 4 mentioned above, a third hydraulic switch may be provided at the outlet of the intercepting facility 13 in the direction of the combined branch pipe 1, and a fourth hydraulic switch may be provided at the outlet of the intercepting facility 13 in the direction of the buffer facility 14.

[0082] Specifically, during the rainy period, the third hydraulic switch is controlled to be closed throughout the whole process, so as to realize the separation of rainwater and sewage during the rainy period, and then during the initial rain, the first hydraulic switch is controlled to be closed and the second hydraulic switch is controlled to be opened, so that the initial rain in the combined branch pipe 1 is diverted to the initial rain storage facility 5 through the first diversion facility 4 for storage. For the middle and late rain, the first hydraulic switch is controlled to be opened and the second hydraulic switch is closed, so that the middle and late rain in the combined branch pipe 1 is diverted to the online treatment facility 11 for treatment through the first diversion facility 4 and the second diversion facility 7 in sequence.

[0083] During the non-rainfall period, when the initial rain in the initial rain storage facility 5 needs to be discharged, the third hydraulic switch is controlled to be closed, and then the first hydraulic switch is controlled to be opened, and the second hydraulic switch is opened. At this time, the initial rain stored in the initial rain storage facility 5 is diverted to the online treatment facility 11 or the sewage treatment facility 12 through the first diversion facility 4 and the second diversion facility 7 in turn, and then discharged to the natural water body after treatment, thereby replenishing the water level in the natural water body during the non-rainfall period.

[0084] Those skilled in the art will understand that the initial rain in the initial rain regulating and storage facility 5 is transported by which of the above-mentioned control methods, and the control can be selected according to actual operational needs; in other words, the present invention does not specifically limit the control and transportation method of the initial rain in the initial rain regulating and storage facility 5. The above-mentioned multiple transportation control methods, as long as they can achieve the storage of a portion of the initial rain at the initial stage of rainfall, thereby reducing the processing pressure of the processing facilities during the entire rainfall cycle, and achieving the technical effect of replenishing the water level in the natural water body during the non-rainfall period, are all applicable to the present invention and are within the scope of protection of the present invention.

[0085] For further information, please refer to Figure 2 , the embodiment of the present invention also includes: a transmitter 8 and a controller 9.

[0086] In detail, the transmitter 8 is used to receive the identification instruction of the current period, and the identification instruction includes one of the following instructions: a first identification instruction for characterizing a non-raining period, a second identification instruction for characterizing that the rainwater is the initial rain in the rainy period, and a third identification instruction for characterizing that the rainwater is the middle and late rain in the rainy period; the controller 9 is respectively connected to the transmitter, the first water switch, the second water switch, the third water switch and the fourth water switch for communication, and the controller 9 includes a memory and a processor, wherein the memory stores a computer program, and when the program is executed by the processor, the following steps can be implemented:

[0087] Receive the identification instruction sent by the transmitter; according to the identification instruction, switch the first water switch, the second water switch, the third water switch and the fourth water switch on and off, wherein the switching specifically includes:

[0088] When the identification instruction is the first identification instruction, the first water switch and the second water switch are controlled to be turned on respectively, so that the initial rain is diverted to the online treatment facility through the first diversion facility, the municipal combined pipe, and the second diversion facility in sequence; or the first water switch is controlled to be turned on, the second water switch is controlled to be turned off, the third water switch is controlled to be turned on, and the fourth water switch is controlled to be turned off, so that the sewage in the sewage branch pipe is diverted to the sewage treatment facility through the first diversion facility, the municipal combined pipe, and the second diversion facility in sequence; or the first water switch is controlled to be turned on, the second water switch is controlled to be turned off, the third water switch is controlled to be turned on, and the fourth water switch is controlled to be turned on, so that the sewage in the buffer facility is diverted to the sewage treatment facility through the first diversion facility, the municipal combined pipe, and the second diversion facility in sequence.

[0089] Specifically, when the identification instruction is the first identification instruction, it means that the current period is a non-rainfall period, and at this time there are at least the following two control modes A1.1, A1.2, and A1.3;

[0090] A1.1, when the rainwater stored in the initial rain storage tank is discharged to the online treatment facility;

[0091] In the A1.1 control mode, there are at least two control modes, A1.1.1 and A1.1.2:

[0092] A1.1.1 The initial rain is diverted to the municipal rainwater pipe through the first diversion facility;

[0093] At this time, the first water switch and the second water switch are controlled to be turned on, the third water switch can be turned off, and the fourth water switch can be turned on. The initial rain is sequentially diverted to the online treatment facility through the first diversion facility, the municipal combined pipe, and the second diversion facility. During this period, the sewage in the sewage branch pipe is intercepted by the interception facility and transported to the buffer facility for storage.

[0094] A1.1.2 Initial rain is not diverted to the municipal stormwater pipe via the first diversion facility;

[0095] That is, at this time, the initial rain is directly pumped back to the municipal stormwater pipe and / or online treatment facility through the first pump. At this time, the first hydraulic switch can be controlled to be closed, the second hydraulic switch can be controlled to be closed, and the third hydraulic switch can be controlled to be opened. Because the initial rain is directly pumped back to the municipal stormwater pipe and / or online treatment facility through the first pump, then for the combined branch pipe, it can receive sewage discharged from the sewage branch pipe through the interception facility, and the sewage flows into the sewage treatment facility through the combined branch pipe, the first diversion facility, the municipal combined pipe and the second diversion facility in turn for treatment.

[0096] Of course, those skilled in the art will understand that the control method for discharging the rainwater stored in the initial rain storage tank to the online treatment facility is specifically through the above-mentioned A1.1.1 control method or the A1.1.2 control method, which can be selected according to actual operational needs; in other words, the present invention does not specifically limit the control method for discharging the rainwater stored in the initial rain storage tank to the online treatment facility, and the above-mentioned two control methods or other control methods for the first hydraulic switch, the second hydraulic switch, the third hydraulic switch and the fourth hydraulic switch, as long as they can realize the discharge of the rainwater stored in the initial rain storage tank to the online treatment facility at the initial stage of rainfall, and do not affect the technical effect of the sewage discharge in the sewage branch pipe, are all applicable to the present invention and are also within the scope of protection of the present invention.

[0097] A1.2, the sewage in the sewage branch pipe is discharged directly after passing through the interception facilities;

[0098] In the A1.2 control mode, the first water switch is controlled to be turned on, the second water switch is controlled to be turned off, the third water switch is controlled to be turned on, and the fourth water switch is controlled to be turned off, so that the sewage in the sewage branch pipe is sequentially transported to the sewage treatment facility through the interception facility, the combined branch pipe, the first diversion facility, the municipal combined pipe, and the second diversion facility for treatment;

[0099] A1.3, the sewage in the buffer facility is discharged directly through the interception facility;

[0100] In the A1.3 control mode, the first water switch is controlled to be turned on, the second water switch is controlled to be turned off, the third water switch is controlled to be turned on, and the fourth water switch is controlled to be turned on, so that the sewage in the buffer facility is transported to the sewage treatment facility for treatment through the intercepting facility, the first diversion facility, the municipal combined pipe and the second diversion facility in sequence.

[0101] Of course, those skilled in the art can understand that when the current identification instruction is the first identification instruction, the controller specifically executes one of the above-mentioned control methods for control, and the control can be selected according to actual operational requirements; in other words, the present invention does not specifically limit the control method of the controller when the current identification instruction is the first identification instruction. The above-mentioned three control methods or other control methods for the first water switch, the second water switch, the third water switch and the fourth water switch, as long as they can achieve the technical effect of reasonably discharging sewage or stored initial rain when the first identification instruction is received, are applicable to the present invention and are within the protection scope of the present invention.

[0102] Furthermore, in the embodiment of the present invention, the two control modes A1.1, A1.2 and A1.3 may also be executed according to a preset priority, for example, A1.3 or A1.1 is executed first, and then A1.2 is executed.

[0103] Specifically, for the initial rain stored in the initial rain regulating and storage facilities, and the sewage stored in the buffer facilities, an initial rain level meter and a sewage level meter can be respectively set in the two facilities, and an initial rain level threshold for characterizing the initial rain capacity and a sewage level threshold for characterizing the sewage capacity can be set, and the initial rain level data signal of the initial rain level meter and the sewage level data signal of the sewage level meter are received in real time through the sensor, and transmitted to the controller in real time. When the initial rain level data signal shows that the initial rain level exceeds the initial rain level threshold, the A1.1 control mode is executed; when the sewage level data signal shows that the sewage level exceeds the sewage level threshold, the A1.3 control mode is executed; when the initial rain level data signal shows that the initial rain level is lower than the initial rain level threshold, and when the sewage level data signal shows that the sewage level is lower than the sewage level threshold, the A1.2 control mode is executed.

[0104] Similarly, those skilled in the art can understand that the execution order of the current A1.1, A1.2 and A1.3 can be selected according to the actual operation requirements. In addition to the execution order of A1.1 or A1.3 being executed first and then A1.2, A1.1 and A1.3 can also be executed simultaneously, and then A1.2, or A1.1, A1.2 and A1.3 can be executed simultaneously. In other words, the present invention does not specifically limit the execution order of A1.1, A1.2 and A1.3. As long as it can be achieved, when the first identification instruction is received, the technical effect of reasonably discharging sewage or stored initial rain is applicable to the present invention and is within the protection scope of the present invention.

[0105] When the identification instruction is not the first identification instruction, the third water switch is controlled to be closed, that is, the sewage in the sewage branch pipe is intercepted by the interception facility; wherein, the identification instruction is not the first identification instruction, which can be understood as the identification instruction is the second identification instruction, or the third identification instruction or other identification instructions described below, and the present invention does not limit it. When the identification instruction is not the first identification instruction, specifically:

[0106] When the identification instruction is the second identification instruction, the first water switch is controlled to be closed and the second water switch is controlled to be opened, so that the initial rain in the combined branch pipe is diverted to the initial rain regulating and storing facility through the first diversion facility for storage;

[0107] When the identification instruction is the third identification instruction, the first water switch is controlled to be turned on and the second water switch is controlled to be turned off, so that the middle and late rain in the combined branch pipe is diverted to the online treatment facility and / or the sewage treatment facility through the first diversion facility, the municipal combined pipe, and the second diversion facility in sequence.

[0108] It should be noted that, in the embodiment of the present invention, the transmitter 110 is used to receive and transmit the identification instruction of the current period, that is, to directly obtain the identification instruction for controlling the controller. The instruction can be directly input manually, or another terminal device or remote terminal can transmit the identification instruction, and transmit it to the controller after receiving the identification instruction. No action is taken on how to obtain this identification instruction. In other words, how to judge whether rainfall occurs and how to judge whether the rain in the rainfall period is the first rain or the middle and late rain can be judged by the judgment method of the prior art. The present invention no longer makes a limitation on the judgment method. As long as it can achieve the method of obtaining the first identification instruction for characterizing the non-rainfall period, the second identification instruction for characterizing the rain as the first rain in the rainfall period, and the third identification instruction for characterizing the rain as the middle and late rain in the rainfall period, or the judgment method, it is applicable to the present invention.

[0109] In this way, when the transmitter 8 receives the second identification instruction, it transmits it to the controller 9, and the controller 9 executes the control instruction of the water conservancy switch to switch. Finally, rainwater and sewage diversion and storage for initial rain are achieved, which reduces the processing pressure of the treatment facilities during the rainy period, alleviates its overloaded working state, and also increases the service life of the treatment facilities, and achieves the technical effect of replenishing the water level in the natural water body during the non-rainy period.

[0110] In the embodiment of the present invention, the initial rain storage facility 5 is a low-lying land or a lake in the unit area or a reservoir arranged in the unit area.

[0111] In the embodiment of the present invention, the online treatment facility 11 is an ecological retention pond, or a biological filter, or a physicochemical treatment facility, or a biochemical treatment facility, or an oxidation pond, or an artificial wetland.
