It will be understood by those skilled in the art that "storm water" and "sewage" in this application are not limitations on the "branch pipe" function, nor are "municipal storm water" limitations on the "pipe" function, but are merely used for differentiation. In other words, the same pipeline, different pipelines, or partially same and partially different pipelines may be used for the rainwater branch pipe, the sewage branch pipe, the municipal rainwater pipe, and the municipal sewage pipe, and the present invention is not limited thereto, and as long as the pipeline capable of realizing liquid transportation is suitable for the present invention, and the present invention is also within the protection scope of the present invention.
The period referred to in the present invention can be divided into a rainfall period and a non-rainfall period according to whether the rainfall behavior occurs, 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 is a period in which no rainfall action occurs, and may be understood as a sunny day. Or according to the size of rainfall, the period referred in the invention can be divided into a rainfall period and a non-rainfall period, wherein the rainfall period refers to the period when the rainfall reaches a certain rainfall threshold value and can be understood as the period when the rainfall is slightly larger; the non-rainfall period is a period opposite to the rainfall period, and refers to a period when the rainfall is less than the rainfall threshold, and may be understood as a period when there is no rainfall or when the rainfall is small.
In the invention, the specific mode of the rainfall period and the non-rainfall period is determined, and the determination is not limited, and can be selected and determined according to the actual operation requirement; in other words, any of the above-described ways of determining periods of rainfall and periods of non-rainfall is suitable for use in the present invention. However, the present invention is applicable to both the determination method of whether rainfall occurs and the determination method of whether the rainfall reaches a certain rainfall threshold, as long as the determination method of whether rainfall occurs or whether the rainfall reaches a certain rainfall threshold can be achieved.
Furthermore, for the rainfall period, the rainwater can be divided into the first rain and the middle and later rain, and the division manner can adopt a time-lapse method, a water quality method or a liquid level method in the prior art, for example, when the time-lapse method is adopted, the corresponding rainwater is the first rain in the rainfall period, and the corresponding rainwater is the middle and later rain in the middle and later periods of the rainfall; if a water quality method is adopted, when the concentration of the rainwater is higher than a certain concentration threshold value, the rainwater is the initial rainwater, and when the concentration of the rainwater is lower than a certain concentration threshold value, the rainwater is the middle and later stage rainwater; if the liquid level method is adopted, the rainwater is the initial rainwater when the liquid level of the rainwater is lower than a certain liquid level threshold, and the rainwater is the middle and later stage rainwater when the liquid level of the rainwater is higher than a certain liquid level threshold.
Similarly, the determination of which mode the initial rain or the middle and later rain belongs to is not limited, and the determination can be selected according to the actual operation requirement; in other words, any of the above-described ways of determining early rain or mid-late rain is suitable for use in the present invention.
Of course, it should be understood by those skilled in the art that since certain errors are allowed in the drainage process of rainwater and/or sewage in the actual operation process, certain errors may exist in the specific division of each period, for example, there is an imprecise division node between the initial rain and the middle and late rain, which results in the early rain mixed with the middle and late rain, or the initial rain/middle and late rain mixed with a small amount of sewage; the operation influence caused by the error does not affect the implementation effect of the whole technical scheme of the invention, and can be ignored, so that the operation influence is not considered to be in the protection range of the invention.
Before describing specific embodiments, it should be noted that the method for treating non-point source pollution provided by the present invention can be applied to a drainage system in a split-flow municipal pipeline, and can also be applied to a drainage system in a combined-flow municipal pipeline to achieve the effect of regulating and storing the initial rain. Those skilled in the art can understand that when the method is directly applied to the combined municipal pipeline, the technical effect of adjusting and storing the initial rain when the method is applied to the split municipal pipeline in the following specific embodiment can be also achieved, and for the application scenario of the method for applying the method to the combined municipal pipeline, details are not described, and the application principle of the method can be referred to the following specific application of the split municipal pipeline.
Example one
Referring to fig. 1, a schematic block diagram of a non-point source pollution treatment device according to an embodiment of the present invention is used for a diversion drainage system in a municipal pipeline, where the diversion drainage system includes a rainwater branch pipe, a sewage branch pipe, and a septic tank. The non-point source pollution treatment equipment comprises: an initial rain storage tank, a flow distribution facility and a treatment facility.
Specifically, the septic tank in the existing community can be the septic tank arranged on the sewage branch pipe (namely, the sewage branch pipe is communicated with the septic tank) as shown in fig. 1, and the existing septic tank is improved into the primary rain storage tank, so that the secondary utilization of the septic tank is realized, and the waste or direct landfill of the septic tank is avoided. That is, the primary rain regulation pool formed by improving the septic tank is communicated with the rainwater branch pipe, a first switch 201 is arranged in the direction that the rainwater branch pipe leads to the primary rain regulation pool, and a second switch 202 is arranged in the direction that the primary rain regulation pool leads to the rainwater branch pipe. Meanwhile, the shunting facility is communicated with the municipal rainwater pipe and is used for shunting the initial rain input by the municipal rainwater pipe; the treatment facility is communicated with the flow dividing facility and is used for treating the initial rain which is divided to the treatment facility.
In the actual operation process, when the rainfall initial stage, can open first switch, the first rain in the rainwater branch pipe at this moment flows into and is stored in the first rain regulation pond that is formed by the septic tank improvement, when the non-rainfall period, can open the second switch and open, the first rain in the first rain regulation pond that is formed by the septic tank improvement this moment flows into the rainwater branch pipe to flow into reposition of redundant personnel facility through municipal rainwater pipe, shunt to handling in the facility by reposition of redundant personnel facility reposition of redundant personnel.
As can be understood by those skilled in the art, in the treatment process, on one hand, the existing septic tank is directly transformed into the primary rain storage tank for storing primary rain, so that compared with the case of directly abandoning or burying the septic tank, the method avoids great resource waste, and greatly reduces the transformation cost increase caused by measures such as landfill; on the other hand, the primary rain is regulated and stored by the primary rain regulation and storage tank formed by improving the septic tank, the existing method that the primary rain is directly discharged to the natural water body, or the primary rain is directly intercepted to the sewage pipe, or a new treatment mode is directly added is replaced, compared with the prior art, the problem that serious non-point source pollution is caused because the primary rain is not directly discharged to the natural water body is solved, the problem that the treatment efficiency of a sewage treatment plant is low is not caused because the primary rain is directly intercepted to the sewage pipe, the problem that the increase of the pipe network laying cost and the operation difficulty are large are not caused because the rainwater pipe is directly added, and the septic tank has the characteristics of simple implementation and wide adaptability.
For the first improvement mode of the septic tank, in order to achieve the effects of simple implementation, low modification cost and the like, the septic tank can be modified in the following mode to form the primary rain storage tank in the embodiment of the invention:
in the circulation direction of the sewage branch pipe, the sewage branch pipe passes through the septic tank through a first pipeline 101 at the water inlet of the septic tank and is communicated with the water outlet of the septic tank through the pipeline.
In the circulation direction of the rainwater branch pipe, the rainwater branch pipe is communicated with the septic tank through a second pipeline 102, and the first switch and/or the second switch are/is arranged on the second pipeline 102.
In detail, in the existing drainage system, the sewage branch pipe is communicated with the water inlet of the septic tank, so that the sewage input by the sewage branch pipe flows into the septic tank and flows into the downstream pipeline from the water outlet of the septic tank, and the embodiment of the invention is based on the structural characteristics that the sewage branch pipe passes through the septic tank through the first pipeline at the water inlet of the septic tank and is communicated with the water outlet of the septic tank through the pipeline, so that the sewage in the sewage branch pipe passes through the septic tank and flows into the downstream pipeline, namely is isolated from the septic tank; simultaneously the rainwater lateral conduit is linked together through second pipeline and septic tank to the first rain that realizes in the rainwater branch pipe can flow in the septic tank through the second pipeline, perhaps flows in the rainwater branch pipe by the first rain of septic tank storage, with this reutilization that realizes the septic tank, directly reforms transform it and can realize carrying out the first rain regulation pond of regulation to first rain, also very big has alleviateed the additional transformation cost of addding first rain regulation pond.
Furthermore, in the embodiment of the invention, for the primary rain storage tank reconstructed from the septic tank, one or more partition walls for blocking slag in the existing septic tank can be removed, so that the water flow in the reconstructed septic tank (namely, the primary rain storage tank) is smooth, the water inlet efficiency of the primary rain is prevented from being influenced by the blockage of the primary rain in the reconstructed septic tank due to the existence of the partition walls, and the technical effect of efficient water inlet is achieved.
It should be noted that, in a first modification of the septic tank, it can be understood that the rainwater branch pipe is communicated with the septic tank through two second pipelines, one second pipeline is used as an input pipeline of the initial rain to communicate the rainwater branch pipe with the septic tank, the other second pipeline is used as an output pipeline of the initial rain to communicate with the septic tank, the first switch is arranged on the second pipeline used as the input pipeline of the initial rain, and the second switch is arranged on the second pipeline used as the output pipeline of the initial rain, so that the input or output of the initial rain is realized by controlling the corresponding second pipeline through the two switches respectively.
For a second improvement mode of the septic tank, in order to achieve the effects of simple implementation, low modification cost and the like, referring to fig. 2, in the embodiment of the present invention, the septic tank may be modified in the following manner to form the primary rain storage tank:
in the circulation direction of the sewage branch pipe, the sewage branch pipe passes through the septic tank through a first pipeline 101 at the water inlet of the septic tank and is communicated with the water outlet of the septic tank through the pipeline.
In the circulation direction of the rainwater branch pipe, the rainwater branch pipe is communicated with the septic tank through a second pipeline 102, and the first switch is arranged on the second pipeline 102.
In detail, compared with the first improvement, the second improvement of the septic tank can be understood that the rainwater branch pipe is communicated with the septic tank through a second pipeline, namely the second pipeline is used as an input pipeline of the initial rain to communicate the rainwater branch pipe with the septic tank, and is also used as an output pipeline of the initial rain to communicate with the septic tank, and at the moment, only the first switch is arranged on the second pipeline to control the on-off of the second pipeline to realize the input or output of the initial rain.
Equally, in the second improvement scheme of septic tank, also can demolish one or more partition walls that are used for blocking the sediment in the current septic tank, and then make the septic tank after the transformation (also just rain regulation pond) inside rivers unobstructed, avoid influencing the efficiency of intaking of just rain then because of having the partition wall and leading to just rain when the septic tank after the transformation circulates, reach the technological effect of high-efficient intaking.
In the embodiment of the invention, the treatment facility is one of an ecological retention pond, a biological filter, a physicochemical treatment facility, a biochemical treatment facility, an oxidation pond or an artificial wetland, is used for carrying out online treatment on the initial rain which is shunted to the treatment facility by the shunting facility, and the treated clean rain can be discharged to a downstream pipeline or a natural water body. The diversion facility may be a diversion well, or may be other devices or apparatuses having a diversion function, and the embodiments of the present invention are not limited, and any facility that can divert rainwater is suitable for the present invention, and is within the protection scope of the present invention.
Further, referring to fig. 4, the processing social security according to the embodiment of the present invention further includes: a transmitter and a controller.
In particular, the transmitter is configured to receive an identification instruction of a current epoch, said identification instruction comprising one of the following instructions: the rain identification method comprises a first identification instruction used for representing that rain water is early rain in a rainfall period, a second identification instruction used for representing that the rain water is middle and later rain in the rainfall period and a third identification instruction used for representing a non-rainfall period. The controller comprises a memory and a processor, wherein the memory stores a computer program that when executed by the processor is capable of performing the steps of: when the identification instruction is a first identification instruction, controlling the first switch to be opened, so that the initial rain input by the rain branch pipes flows into a plurality of initial rain storage tanks for storage; when the identification instruction is a second identification instruction, controlling the first switch to be turned off, so that the middle-later stage rain input by the rainwater branch pipe flows into a downstream pipeline or a natural water body through the rainwater branch pipe, the municipal rainwater pipe and the diversion facility in sequence; when the identification instruction is a third identification instruction, the second switch is controlled to be turned on, so that the initial rain stored in the initial rain storage tank is input into the rainwater branch pipe and flows through the rainwater branch pipe, the municipal rainwater pipe and the flow dividing facility to the treatment facility in sequence for treatment.
It can be understood that when the received current instruction is the first identification instruction, the current period is the initial stage of rainfall, the received current instruction is the period of beginning to rain, the rain is turbid, the pollution degree is large, if the initial rain at the stage is directly discharged to a natural water body, serious non-point source pollution is easily caused to the water body, or the initial rain is directly discharged to a sewage pipe at the source, because the concentration of the initial rain is usually lower than that of domestic sewage, the initial rain is discharged to the sewage treatment plant through the sewage pipe, the inlet water concentration of the sewage treatment plant is easily reduced, and the treatment efficiency of the sewage treatment plant is influenced; or adopt the measure of damming to cut off the first rain to the sewage pipe network, send to sewage treatment plant and handle and discharge, but because the sewage pipe network of present situation does not consider this partial water yield of first rain when designing, so in reality first rain can't be cut off to the sewage pipe network, and if cut off first rain to first rain pipe, then need newly build one set of first rain pipe in the city, cut off the first rain in the city, but the city has two sets of pipe networks of rain and sewage, when newly building one set of first rain pipe network, the construction degree of difficulty is very big, the cycle is also very long, investment cost is also very high. Therefore, when the received current instruction is the first identification instruction, the first switch is controlled to be turned on, so that the initial rain input from the rainwater branch pipe flows into the initial rain storage tank communicated nearby for storage, and the direct discharge to a sewage pipe or a natural water body or a sewage treatment plant is avoided. In order to reduce regional pollution in a large area, namely non-point source pollution, the drainage system is provided with a plurality of initial rain storage tanks, so that initial rain in a plurality of dispersed areas is correspondingly stored through the plurality of initial rain storage tanks, and the purpose of reducing the non-point source pollution is achieved.
Certainly, when the received current instruction is the second identification instruction, the current period is the middle and later periods of rainfall, rainwater is clear, the pollution degree is low, and rainwater in the middle and later periods of the time can be directly shunted to a downstream pipeline or a natural water body through the rainwater branch pipe, the municipal rainwater pipe and the shunting facility, so that non-point source pollution to the natural water body is avoided.
Meanwhile, when the received current instruction is the third identification instruction, the current period is a non-rainfall period at the moment, the current period can be understood as a fine day or a light rainy day, and the second switch is controlled to be turned on at the moment, so that the initial rain stored in the initial rain storage tank is input into the rainwater branch pipe and is sequentially shunted to the treatment facility through the rainwater branch pipe, the municipal rainwater pipe and the shunting facility for treatment.
It should be noted that, in the above embodiment, the transmitter is used to receive and transmit the identification command of the current period, that is, directly obtain the identification command for controlling the controller, the command may be directly input by a human, or another terminal device or a remote terminal may transmit the identification command, and transmit the identification command to the controller after receiving the identification command, and the determination is performed according to one or more of the following methods in the prior art, such as a liquid level method, a water quality method, a rain amount method, a total amount method, a time method, and the like, instead of determining whether the rainfall occurs or not, and determining whether the rainfall in the rainfall period is early rain or late rain, as long as the obtaining manner or the determining manner of the corresponding command can be implemented, are all suitable for use in the present invention.
Of course, it should be noted that the septic tank in the embodiment of the present invention may also be a septic tank disposed on the rainwater branch pipe as shown in fig. 3 (i.e., the rainwater branch pipe is communicated with the septic tank). That is, the initial rain storage tank formed by improving septic tanks in existing communities (or other buildings, such as schools, office buildings, and other areas) may be a septic tank located on the sewage branch pipe, or a septic tank located on the rainwater branch pipe.
