Description

Pipe network system based on rain and sewage diversion

Technical Field

The invention belongs to the technical field of municipal drainage, and particularly relates to a pipe network system based on rain and sewage diversion.

Background

Municipal drainage systems in cities are mainly divided into a confluence drainage system and a diversion drainage system. The earliest confluence drainage system mixes sewage, industrial wastewater and rainwater in the same pipe canal, directly discharges the sewage into water nearby without any treatment, and easily causes serious pollution to the receiving water. The diversion drainage system is a system for draining domestic sewage, industrial wastewater and rainwater in two or more independent pipelines respectively.

Currently, in the existing municipal drainage technology, most of the combined cells have the following problems:

(1) In rainy days, rainwater is divided into primary rainwater and middle-stage and later-stage rainwater according to a time-long method, a water quality method or a liquid level method, and the primary rainwater is generally split into municipal sewage pipes for reuse after being treated by a sewage treatment plant in a primary rainwater discharge mode, however, the sewage pipes have limited conveying capacity and cannot accommodate a large amount of mixed water of sewage and rainwater, if the sewage pipes are modified, the cost is too high, and the mixed water mixed with the sewage and the primary rainwater is also insufficient in capacity of the sewage treatment plant or waste of treatment resources due to the fact that the mixed water mixed with the sewage and the primary rainwater is sent into the sewage treatment plant for treatment due to the large quantity; in addition, in sunny days, as the initial rain is treated and discharged in rainy days, the water treatment discharge amount of the water is only related to domestic sewage, so that the condition that no water is supplied along the river channel due to insufficient water treatment discharge amount in long-term sunny days is easily caused, and the river channel is dried.

(2) On one hand, in rainy days, a large amount of sewage is mixed in the rainwater flowing out of the converging branch pipe because the rainwater is not split into rainwater and sewage in the pipeline system in the converging district, and at the moment, if the part of sewage is conveyed to a municipal rainwater pipe, natural water connected with the municipal rainwater pipe is extremely easy to be polluted; on the other hand, sewage and rainwater which continuously flow into the converging branch pipe are diluted by rainwater, but the concentration of pollutants in the sewage is higher, so that the middle-stage and later-stage rainwater flowing out of the converging branch pipe is also sewage, if the middle-stage and later-stage rainwater flows into a municipal rainwater pipe, natural water is polluted, and when the middle-stage and later-stage rainwater is conveyed to the municipal sewage pipe, the capacity of the municipal sewage pipe is limited, the middle-stage and later-stage rainwater cannot be contained, if the municipal sewage pipe is reformed, the cost is too high, and the middle-stage and later-stage rainwater mixed with domestic sewage is greatly conveyed into a sewage treatment plant for treatment, and the capacity of the sewage treatment plant is insufficient, or the treatment resource is wasted.

Therefore, in the existing municipal drainage technology, the technical defects that the rainwater is not split during the treatment and the discharge of rainwater in the combined system district in rainy days, the treatment pressure of the treatment facilities is high, the treatment facilities operate in an overload mode, the service life of the treatment facilities is reduced, and the condition that no water is supplemented along the river channel due to insufficient water treatment discharge amount during sunny days is extremely easy to cause the river channel to dry are overcome.

All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention are within the scope of the present invention; wherein the "and/or" keywords referred to in this embodiment denote and/or both cases, in other words, a and/or B mentioned in the embodiments of the present invention denote both cases a and B, A or B, and three states in which a and B exist are described, such as a and/or B, and denote: only A and not B; only B and not A; includes A and B.

Also, in embodiments of the present invention, when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" or "in communication with" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right" and the like are used in the embodiments of the present invention for illustrative purposes only and are not intended to limit the present invention.

It should be noted that, in order to describe the present invention in more detail, so that those skilled in the art can understand the present invention more clearly and clearly, and further support the technical problems to be solved by the present invention and the corresponding technical effects to be achieved, before describing the present invention, the following explanation is made with respect to the term nouns involved in the present invention:

a merging branch pipe which is a pipe for conveying rainwater, sewage or mixed water of rainwater and sewage in the unit area pipe; a sewage branch pipe, which is a pipe for transporting sewage in the unit area pipe; the municipal rainwater pipe is a pipeline for conveying rainwater in municipal pipelines; municipal sewage pipes are pipes used for transporting sewage in municipal pipelines.

It will be appreciated by those skilled in the art that the above-described "stormwater", "sewage", "mixed water" are not limiting of the "manifold" function, nor are the "municipal stormwater", "municipal sewage" are limiting of the "manifold" function, but merely serve as a distinction. In other words, the converging branch pipe, the sewage branch pipe, the municipal rainwater pipe and the municipal sewage pipe can all use the same pipeline, or different pipelines, or pipelines with the same part and different parts, so the invention is not limited, and the pipelines which can realize liquid conveying are suitable for the invention and are also within the protection scope of the invention.

According to whether or not the rainfall behavior occurs, the periods involved in the present invention can be divided into a rainfall period and a non-rainfall period, wherein the rainfall period refers to the period in which the rainfall behavior occurs and can be understood as a rainy day; the non-rainfall period is a period opposite to the rainfall period, and refers to a period in which no rainfall behavior occurs, and can be understood as a sunny day. Or according to the rainfall, the period related to the invention can be divided into a rainfall period and a non-rainfall period, wherein the rainfall period refers to a period when the rainfall reaches a certain rainfall threshold value, and can be understood as a period when the rainfall is slightly larger; the non-rainfall period is a period of time opposite to the rainfall period, and is a period of time when the rainfall is less than the rainfall threshold, and is understood to be a period of time when there is no rainfall or when the rainfall is small.

In the invention, the specific mode of determining the rainfall period and the non-rainfall period is not limited, and the method can be selected and determined according to actual operation requirements; in other words, any of the above-described ways of determining the rainfall period and the non-rainfall period is applicable to the present invention. And how to judge whether rainfall occurs or not and how to judge whether rainfall reaches a certain rainfall threshold value or not, the judgment mode of the prior art is adopted, the invention does not aim at the judgment mode of whether rainfall occurs or not, and a determination mode for determining whether the rainfall reaches a certain rainfall threshold is limited, so long as the determination mode for obtaining whether rainfall occurs or whether the rainfall reaches a certain rainfall threshold can be realized, the method is suitable for the invention.

Furthermore, for the rainfall period, the rainwater can be divided into primary rainwater and middle and late stage rainwater, and the dividing mode can adopt a time-length method, a water quality method or a liquid level method in the prior art, for example, when the time-length method is adopted, the corresponding rainwater in the rainfall period is primary rainwater, and the corresponding rainwater in the middle and late stage rainfall is middle and late stage rainwater; if the water quality method is adopted, the rainwater is first rain when the concentration of the rainwater is higher than a certain concentration threshold value, and is middle-stage and later-stage rain when the concentration of the rainwater is lower than a certain concentration threshold value; if the liquid level method is adopted, the rainwater is first rain when the liquid level of the rainwater is lower than a certain liquid level threshold value, and is middle-late stage rain when the liquid level of the rainwater is higher than a certain liquid level threshold value.

Similarly, the mode of determining the first rain or the middle and later rain is not limited, and the mode can be selected and determined according to actual operation requirements; in other words, any of the above-described ways of determining the initial rain or the middle-late rain is applicable to the present invention.

Of course, it should be understood by those skilled in the art that, since certain errors are allowed in the actual process of draining rainwater and/or sewage, certain errors may exist in the specific division of each period, such as that the division nodes are not strict in the middle of the initial rain and the middle and late rain, so that the initial rain is mixed with the middle and late rain, or the initial rain/middle and late rain is mixed with a small amount of sewage, etc.; the operation effect caused by the error is negligible because the implementation effect of the whole technical scheme of the invention is not influenced, and the operation effect is not considered to be within the protection scope of the invention.

Example 1

Referring to fig. 1 specifically, a schematic overall structure of a pipe network system based on diversion of rain and sewage is provided in an embodiment of the present invention when applied to a drainage system, where the drainage system includes a converging branch pipe 1, a sewage branch pipe 2, and a gully 3; the pipe network system based on rain and sewage diversion specifically comprises: a sewage interception pipe 6, a first diversion facility 4, a primary rain regulation facility 5, a second diversion facility 7 and an interception facility 15.

The converging branch pipe 1 is connected with the rain inlet 3 and is commonly used for conveying rainwater, so that the first rain and the middle and later rain in the rainfall period are conveyed after being converged into the converging branch pipe 1 through the rain inlet 3, the number of the rain inlet 3 can be multiple, the distribution position of the plurality of rain inlets 3 in a unit area can be any position, and the rainwater collecting branch pipe can be reasonably arranged according to the actual rain collecting direction in the actual process. The sewage branch pipe 2 is communicated with the municipal sewage pipe 10, so that the sewage in the unit area is firstly collected into the sewage branch pipe 2, and then the sewage is intensively conveyed into the confluence branch pipe 1 by the sewage branch pipe 2 and then enters the municipal sewage pipe 10; the municipal sewage pipe 10 may be connected to a sewage treatment facility 12 (e.g., a sewage treatment plant), and sewage is treated by the sewage treatment facility 12 and discharged.

Wherein, the embodiment of the invention is provided with the interception facility 15 between the sewage branch pipe 2 and the municipal sewage pipe 10, so as to intercept the sewage in the sewage branch pipe 2 through the interception facility 15, for example, during the rainfall period, the sewage is intercepted so as not to flow into the confluence branch pipe, thereby realizing the rain and sewage diversion in the confluence branch pipe during the rainfall period, and during the non-rainfall period, the sewage is released so as to flow into the confluence branch pipe 1. Meanwhile, a buffer facility 16 is connected to the intercepting facility 15 to intercept the sewage during intercepting into the buffer facility 16 through the intercepting facility 15 for storage, thereby achieving the effect that the normal discharge of the sewage in the unit area is not affected even during intercepting in a rainfall period.

As yet another embodiment, the intercepting facility is one of a diversion well, an intercepting well, a discarding well, a buffer gallery or an installation well, and the buffer facility is a tank structure or a tank structure having a storage space; the two are independent from each other.

Of course, those skilled in the art will understand that, in particular, the intercepting facility 15 and the buffering facility 16 are used to intercept and store sewage according to the above embodiments, and may be selected according to actual operation requirements; in other words, the specific structures of the intercepting means 15 and the buffering means 16 are not particularly limited, and the above two embodiments, and similar embodiments in the prior art, are applicable to the present invention as long as the technical effect of storing the sewage in the sewage branch pipe 2 from the intercepting means 16 can be achieved, and are also within the scope of protection of the present invention.

In addition, in the present invention, a first diversion facility 4 and a first rain regulation facility 5 are provided in the downstream direction of the merging branch pipe 1, the first diversion facility 4 is respectively communicated with the merging branch pipe 1 and the municipal rainwater pipe 11, and the first rain regulation facility 5 is communicated with 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 three water outlets, namely, the water inlet of the first diversion facility 4 is communicated with the confluence branch pipe 1 and is respectively corresponding to the first rain regulation facility 5, the municipal rainwater pipe 11 and the sewage interception pipe 6 through the three water outlets.

So that the sewage in the sewage branch pipe 2 is intercepted by the intercepting facility 15 in the rainfall period, the intercepted sewage flows into the buffering facility 16 for storage, the first diversion facility 4 is used for diverting the primary rain in the rainfall period in the combined branch pipe 1, and the primary rain is stored after being diverted by the first diversion facility 4 by the primary rain regulation facility 5; of course, the starting time of the intercepting facility 15 for intercepting the sewage in the sewage branch pipe 2 and the starting time of the intercepting process of the first diversion facility 4 in the rainfall period in the merging branch pipe 1 can be the same time, namely, the two starting times are simultaneously carried out, the intercepting process of the intercepting facility 15 for intercepting the sewage in the sewage branch pipe 2 can be carried out before the intercepting process of the first diversion facility 4 in the rainfall period in the merging branch pipe 1, the control sequence is not limited, so long as the intercepting process of the sewage in the sewage branch pipe 2 through the intercepting facility 15 in the rainfall period and the control mode of the intercepting process of the first rain in the rainfall period in the merging branch pipe 1 through the first diversion facility 4 are both suitable for the invention, and the intercepting process of the first rain in the rainfall period in the merging branch pipe 1 is also within the protection scope of the invention, thereby effectively avoiding the defects of overlarge treatment pressure of the sewage treatment facility, resource waste and the like caused when the municipal sewage pipe is conveyed to the sewage treatment facility for treatment, the sewage treatment facility effectively reducing the treatment pressure of the sewage treatment facility in the rainfall period, reducing the treatment operation load of the sewage treatment facility in the rainfall period, and improving the working cost of the sewage treatment facility, and improving the service life of the sewage treatment facility. And for the non-rainfall period, the first diversion facility 4 and the second diversion facility 7 are sequentially used for diversion of the initial rain to the on-line treatment facility 13 for treatment in the non-rainfall period, and then the initial rain flows into the natural water body or the downstream pipeline, so that the technical defect of river channel dryness caused when sewage is only treated and discharged in the non-rainfall period is effectively avoided, and the river water is effectively supplied.

As an implementation manner of implementing the diversion action of the first diversion facility 4, an embodiment of the present invention may include a first water conservancy switch and a second water conservancy switch. The first water conservancy switch is arranged at a water outlet of the first diversion facility 4 in the direction of leading to the municipal rainwater pipe 11; the second water conservancy switch is arranged at a water outlet of the first diversion facility 4, which leads to the direction of the primary rain regulation facility 5.

And when not rainfall period, control first hydraulic switch and second hydraulic switch to open, the first rain that stores in the first rain regulation facility 5 at this moment shunts to the online processing facility 13 in proper order through first reposition of redundant personnel facility 4, second reposition of redundant personnel facility 7 and discharges to the nature water after handling, and then realize adjusting the storage to first rain in the rainfall period, alleviate the process pressure of handling the facility, also avoid the wasting of resources simultaneously, also can realize simultaneously supplying the water level in the nature water in the non-rainfall period.

As a further implementation of the diversion action of the first diversion facility 4, the embodiment of the present invention may also comprise a first pump; the first pump is arranged in the primary rain regulation facility 5 to pump primary rain from the primary rain regulation facility 5 to the municipal rainwater pipe 11 or the second diversion facility 7.

Specifically, the first hydraulic switch is controlled to be turned off and the second hydraulic switch is controlled to be turned off during a rainfall period, so that the primary rain in the confluence branch pipe 1 is shunted to the primary rain regulation facility 5 for storage through the first shunting facility 4, and for middle-stage and later-stage rain, the first hydraulic switch is controlled to be turned off and the second hydraulic switch is controlled to be turned on, so that the middle-stage rain or later-stage rain in the confluence branch pipe 1 is shunted to the on-line treatment facility 13 for treatment through the first shunting facility 4 and the second shunting facility 7 in sequence. And during non-rainfall period, the first water conservancy switch is controlled to be turned on, and the second water conservancy switch is controlled to be turned on, at this moment, the initial rain stored in the initial rain regulation facility 5 is shunted to the online treatment facility 13 through the first shunting facility 4 and the second shunting facility 7 in sequence and then discharged to the natural water body, and then the initial rain is regulated and stored during the rainfall period, the treatment pressure of the treatment facility is reduced, and simultaneously, resource waste is avoided, and meanwhile, the water level in the natural water body can be supplied during the non-rainfall period, and when the water discharge requirement is very high, the first pump is controlled to synchronously suck the initial rain in the initial rain regulation facility 5 back to the second shunting facility 7 or the online treatment facility 13, so that the problem that the current water supply cannot be met only by turning on the second water conservancy switch is solved, or the first water conservancy switch can be turned off when the initial rain in the initial rain regulation facility 5 is sucked back through the first pump is solved.

As can be appreciated by those skilled in the art, the primary rain in the primary rain regulation facility 5 is specifically transported to the second diversion facility 7 or the on-line processing facility 13 through the above embodiment, and the primary rain can be selectively controlled according to actual operation requirements; in other words, the present invention is not limited to the primary rain conveying manner in the primary rain regulation facility 5, and the two conveying manners and the similar conveying manner in the prior art are applicable to the present invention as long as the technical effect of remotely conveying the primary rain in the primary rain regulation facility 5 to the second diversion facility 7 or the on-line processing facility 13 can be achieved, and are also within the protection scope of the present invention.

And for the middle-stage and later-stage rain, the first hydraulic switch is controlled to be turned on and the second hydraulic switch is controlled to be turned off, and meanwhile, the third hydraulic switch is controlled to be turned off, so that the middle-stage and later-stage rain in the converging branch pipe 1 is sequentially shunted to the on-line treatment facility 13 for treatment through the first shunting facility 4 and the second shunting facility 7. Or when the amount of the middle-stage and later-stage rain water is large, the first water conservancy switch is controlled to be turned on and the second water conservancy switch is controlled to be turned off, and the third water conservancy switch is controlled to be turned on, so that a part of the middle-stage and later-stage rain water in the converging branch pipe 1 is sequentially shunted to the on-line treatment facility 13 through the first shunting facility 4 and the second shunting facility 7 and then discharged; the other part is discharged after being conveyed to a sewage treatment facility for treatment through a interception pipe 6 and a municipal sewage pipe 10 in sequence, so as to lighten the treatment capacity of the treatment facility.

And when the first rain in the first rain regulation facility 5 is required to be discharged in a non-rainfall period, the fourth water conservancy switch is controlled to be turned off, the first water conservancy switch is controlled to be turned on, the second water conservancy switch is controlled to be turned on, and the third water conservancy switch is controlled to be turned off at the same time when the second water conservancy switch is turned on, and the first rain stored in the first rain regulation facility 5 is sequentially shunted to the on-line treatment facility 13 through the first shunting facility 4 and the second shunting facility 7 and then discharged to the natural water body, so that the water level in the natural water body is supplied in the non-rainfall period.

Those skilled in the art can understand that the primary rain in the primary rain regulation and storage facility 5 is specifically conveyed by the control mode, and the primary rain can be selectively controlled according to actual operation requirements; in other words, the present invention is not limited to the control and transportation method of the primary rain in the primary rain regulation facility 5, and the above-mentioned various transportation control methods are applicable to the present invention as long as the primary rain is stored in a part during the initial period of rainfall, so that the processing pressure of the processing facility is reduced during the whole rainfall period, and the technical effect of replenishing the water level in the natural water body during the non-rainfall period is achieved.

Still further, referring to fig. 2, the embodiment of the present invention further includes: a conveyor 8 and a controller 9.

In detail, the transmitter 8 is configured to receive an identification instruction of the current period, where the identification instruction includes one of the following instructions: a first identification instruction for characterizing a non-rainfall period, a second identification instruction for characterizing a first rain of the rainfall period, and a third identification instruction for characterizing a middle and late rain of the rainfall period; the controller 9 is in communication connection with the transmitter 8, the first hydraulic switch, the second hydraulic switch, the third hydraulic switch, the fourth hydraulic switch, the fifth hydraulic switch and/or the first pump respectively, and is used for controlling the actions of the first hydraulic switch, the second hydraulic switch, the third hydraulic switch and/or the first pump according to the monitoring result of the transmitter 8.

Wherein the controller 9 comprises a memory and a processor, wherein the memory stores a computer program which, when executed by the processor, is capable of performing the steps of:

Receiving an identification instruction sent by the transmitter; according to the identification instruction, the first hydraulic switch, the second hydraulic switch, the third hydraulic switch, the fourth hydraulic switch and the fifth hydraulic switch are switched, and the switching specifically comprises:

When the identification instruction is a first identification instruction, respectively controlling the first water conservancy switch to be turned on and the second water conservancy switch to be turned on, so that the initial rain is sequentially shunted to the on-line treatment facility through the first shunting facility and the second shunting facility; or the first water conservancy switch is controlled to be closed, the second water conservancy switch is controlled to be closed, the third water conservancy switch is controlled to be opened, the fourth water conservancy switch is controlled to be opened, and the fifth water conservancy switch is controlled to be opened, so that the sewage in the buffer facility is sequentially conveyed to a sewage treatment facility for treatment through the first diversion facility and the municipal sewage pipe; or the first water conservancy switch is controlled to be closed, the second water conservancy switch is controlled to be closed, the third water conservancy switch is controlled to be opened, the fourth water conservancy switch is controlled to be opened, and the fifth water conservancy switch is controlled to be closed, so that the sewage in the sewage branch pipe is sequentially conveyed to a sewage treatment facility for treatment through the intercepting facility, the converging branch pipe, the first diversion facility, the sewage intercepting pipe and the municipal sewage pipe;

Specifically, when the identification command is a first identification command, that is, the current period is a non-rainfall period, at least three control modes A1.1, A1.2 and A1.3 exist at the moment;

a1.1, when the stored rainwater in the primary rain regulation reservoir is discharged to an online treatment facility;

in this a1.1 control scheme, there are at least two control schemes, A1.1.1 and A1.1.2, as follows:

A1.1.1 the primary rain is split to a municipal rainwater pipe through a first splitting facility;

At the moment, the first water conservancy switch is controlled to be turned on, the second water conservancy switch is controlled to be turned on, the third water conservancy switch can be turned off, the fourth water conservancy switch can be turned off, and the fifth water conservancy switch can be turned on, and initial rain is sequentially shunted to the online treatment facility through the first shunting facility and the second shunting facility, and during the period, sewage in the sewage branch pipe is intercepted by the intercepting facility and stored in the buffering facility;

a1.1.2 the primary rain is not split to the municipal rainwater pipe through the first splitting facility;

that is, the first water conservancy switch is turned off, the second water conservancy switch is turned off, the third water conservancy switch is turned on, the fourth water conservancy switch is turned on, and the fifth water conservancy switch is turned on at this time, so that the first rain is directly pumped back to the municipal rainwater pipe and/or the on-line treatment facility through the first pump, and then the converging branch pipe can receive sewage discharged by the sewage branch pipe or the buffer facility through the intercepting facility in sequence, and the sewage flows into the sewage treatment facility through the converging branch pipe, the first diversion facility and the intercepting pipe in sequence for treatment.

Of course, those skilled in the art can understand that the control mode of the method for discharging the stored rainwater in the primary rain regulation reservoir to the on-line treatment facility is specifically the A1.1.1 control mode or the A1.1.2 control mode, and the control can be selected according to the actual operation requirement; in other words, the control manner of the invention when the stored rainwater in the primary rain regulation reservoir is discharged to the on-line treatment facility is not particularly limited, and the above 2 control manners or other control manners for the first hydraulic switch, the second hydraulic switch, the third hydraulic switch, the fourth hydraulic switch and the fifth hydraulic switch are applicable to the invention, and are also within the scope of protection of the invention as long as the stored rainwater in the primary rain regulation reservoir can be discharged to the on-line treatment facility at the initial stage of rainfall, and the technical effects of storing or discharging sewage in the sewage branch pipe are not affected.

A1.2, discharging the sewage in the buffer facility;

In the control mode of A1.2, the first water conservancy switch is controlled to be closed, the second water conservancy switch is controlled to be closed, the third water conservancy switch is controlled to be opened, the fourth water conservancy switch is controlled to be opened, and the fifth water conservancy switch is controlled to be opened, so that sewage in the buffer facility sequentially passes through the first diversion facility and the municipal sewage pipe and is conveyed to a sewage treatment facility for treatment.

Of course, it can be understood by those skilled in the art that when the current identification instruction is the first identification instruction, the controller specifically executes which control mode to control, and can select control according to actual operation requirements; in other words, the control mode of the controller is not specifically limited when the current identification instruction is the first identification instruction, and the above 3 control modes or other control modes for turning on the first hydraulic switch, turning on the second hydraulic switch, turning off the third hydraulic switch, turning off the fourth hydraulic switch and turning on the fifth hydraulic switch are all applicable to the present invention as long as the technical effect of reasonably discharging sewage or stored initial rain when the first identification instruction is received can be achieved, and are also within the protection scope of the present invention.

Further, in the embodiment of the present invention, the three control modes a1.1, a1.2 and a1.3 may also be executed according to a preset priority, for example, a1.1 or a1.2 is preferentially executed, and then a1.3 is executed.

Specifically, for the initial rain stored in the initial rain regulation facility and the sewage stored in the buffer facility, an initial rain level meter and a sewage level meter can be respectively and correspondingly arranged in the two facilities, an initial rain level threshold value for representing the initial rain capacity and a sewage level threshold value for representing the sewage capacity are set, and an initial rain level data signal of the initial rain level meter and a sewage level data signal of the sewage level meter are received in real time through a sensor and transmitted to a controller in real time. When the primary rain liquid level data signal shows that the primary rain liquid level exceeds a primary rain liquid level threshold, executing an A1.1 control mode; when the sewage liquid level data signal shows that the sewage liquid level exceeds a sewage liquid level threshold value, executing an A1.2 control mode; and when the primary rain liquid level data signal shows that the primary rain liquid level is lower than the primary rain liquid level threshold value, and when the sewage liquid level data signal shows that the sewage liquid level is lower than the sewage liquid level threshold value, executing an A1.3 control mode.

Similarly, it will be understood by those skilled in the art that the execution sequence of the current a1.1, a1.2 and a1.3 may be selected according to the actual job requirement, and in addition to the execution sequence of preferentially executing a1.1 or a1.2 and then executing a1.3, the execution sequence may also be that simultaneously executing a1.1 and a1.2 and then executing a1.3, or simultaneously executing a1.1, a1.2 and a1.3. In other words, the execution sequence of the A1.1, the A1.2 and the A1.3 is not particularly limited, so long as the method can realize the technical effect of reasonably discharging sewage or stored initial rain when receiving the first identification instruction, the method is applicable to the invention, and the method is also within the protection scope of the invention.

When the identification instruction is a non-first identification instruction, the third water conservancy switch and the fourth water conservancy switch are controlled to be turned off, namely, sewage in the sewage branch pipe is intercepted through a interception facility, and meanwhile, in order to prevent rainwater in the first diversion facility from penetrating into the sewage interception facility, the third water conservancy switch can be also controlled to be turned off at the moment; the recognition instruction is not the first recognition instruction, which may be understood as the second recognition instruction, the third recognition instruction, or other recognition instructions, which are described below, and the present invention is not limited thereto. When the identification instruction is a non-first identification instruction, the method specifically comprises the following steps:

When the identification instruction is a second identification instruction, the first water conservancy switch is controlled to be turned off and the second water conservancy switch is controlled to be turned on, and the third water conservancy switch is controlled to be turned off and the fourth water conservancy switch is controlled to be turned off, so that the primary rain in the converging branch pipe is shunted to the primary rain regulation and storage facility for storage through the first shunting facility;

Or the first hydraulic switch is controlled to be opened and the second hydraulic switch is controlled to be closed, and the third hydraulic switch is controlled to be opened, so that a part of the middle-stage rain in the confluence branch pipe 1 is sequentially shunted to the on-line treatment facility 13 through the first shunting facility 4 and the second shunting facility 7 and then discharged; the other part is delivered to the sewage treatment facility for treatment through the interception tube 6 and the municipal sewage pipe 10 in sequence and then discharged, so that overload operation of the treatment facility caused by large rain and rain amount in the middle and later stages is avoided, and the service life period of the treatment facility is prolonged.

When the transmitter 8 receives the first identification instruction, it is transmitted to the controller 9, and at this time, the controller 9 performs control according to the above three control modes a1.1, a1.2 and a1.3, which are not described herein in detail.
