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 utility model 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 utility model, 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.

A water inlet 101 of a primary rain storage tank formed by improving a septic tank is communicated with a rainwater branch pipe, a first switch 201 is arranged at the water inlet, a water outlet 102 of the primary rain storage tank is communicated with a primary rain collecting port 103 for outputting primary rain, and a second switch 202 is arranged at the water outlet.

In the actual operation process, at the early stage of rainfall, the first switch can be opened, the initial rain in the rainwater branch pipe flows into the initial rain storage tank formed by improving the septic tank to be stored, at the non-rainfall period, the second switch can be opened, and the initial rain in the initial rain storage tank formed by improving the septic tank flows into the initial rain collecting port to be output through the initial rain collecting port.

The technical personnel in the field can understand that in the treatment process, the embodiment of the utility model directly transforms the existing septic tank into the primary rain storage tank for storing primary rain, avoids great resource waste compared with directly abandoning or burying the septic tank, greatly reduces the transformation cost increase caused by measures such as landfill, and has the characteristics of simple implementation, low transformation cost, simple implementation and wide adaptability.

For an 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 utility model:

in the circulation direction of the sewage branch pipe, the sewage branch pipe passes through the septic tank through a first pipeline 301 at the water inlet pipe of the septic tank and is communicated with the water outlet pipe 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 302;

a water outlet is formed in the septic tank so as to be communicated with the primary rain collecting port through the water outlet.

In detail, in the existing drainage system, the sewage branch pipe is communicated with the water inlet pipe 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 by the water outlet pipe of the septic tank, and the embodiment of the utility model is based on the structural characteristics that the sewage branch pipe passes through the septic tank through the first pipeline at the water inlet pipe of the septic tank and is communicated with the water outlet pipe 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 lateral conduit can flow in the septic tank through the second pipeline, with this reutilization that realizes the septic tank, directly reforms its first rain regulation pond that can realize carrying out the regulation to first rain, also very big has alleviateed the additional transformation cost who adds first rain regulation pond.

Furthermore, in the embodiment of the utility model, 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 the embodiment of the present invention, there may be several methods for outputting the initial rain in the initial rain storage tank, specifically:

in a first mode, referring to fig. 1, when the initial rain collecting port is opened on the (nearby) sewage branch pipe, the initial rain in the initial rain storage tank can be conveyed to the sewage branch pipe through the initial rain collecting port, and then conveyed to the downstream pipeline through the sewage branch pipe.

In a second mode, referring to fig. 2, when the initial rain collecting port is communicated with the initial rain processing facility, the initial rain in the initial rain storage tank can be delivered to the initial rain processing facility through the initial rain collecting port, and the initial rain processing facility is one of the following: biological grass-planting ditches, sunken greenbelts or rain water gardens. It can be understood that the purpose of treating the initial rain nearby is achieved by utilizing the natural facilities on site to discharge nearby, for example, the rainwater garden is a rainwater runoff treatment system with simple structure, convenient installation, less maintenance and low cost, when the initial rain is output to the rainwater garden, pollutants such as particulate matters, organic matters, nitrogen, phosphorus, heavy metals and the like in the rainwater can be removed in a targeted manner through the rainwater garden, and the treated rainwater can permeate underground, and can be discharged to natural water or municipal pipe networks or recycled. Since the biological grass planting furrows, the sunken greenbelts or the rain water gardens belong to mature greening facilities in the prior art, and the embodiments of the present application are not described in detail, it can be understood by those skilled in the art that the biological grass planting furrows, the sunken greenbelts or the rain water gardens are only examples of the early rain treatment facilities in the embodiments of the present application, and are not limited thereto.

In a third mode, referring to fig. 3, when the first rain collecting port is communicated with the first rain recovery pipe, the first rain in the first rain storage tank can be conveyed to the first rain recovery pipe through the first rain collecting port to be recovered, so as to achieve the technical effect of recovering and reusing the first rain.

Further, referring to fig. 5, the processing apparatus 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 first identification instruction is used for representing that the rainwater is early rain in the rainfall period, the second identification instruction is used for representing that the rainwater is middle and later rain in the rainfall period, and the third identification instruction is used for representing the 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 pipe flows into the initial rain storage tank for storage; and when the identification instruction is a third identification instruction, controlling the second switch to be switched on, so that the initial rain stored in the initial rain storage tank is input to the initial rain collecting port and is output through the initial rain collecting port.

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 initial stage of rainfall, the rainwater is turbid, the pollution degree is high, if the initial rain at the stage is directly discharged to a natural water body, serious non-point source pollution is extremely easily caused to the water body, if the initial rain is intercepted to an initial rain pipe, a set of initial rain pipe needs to be newly built in a city, the initial rain in the city is intercepted, however, two sets of rain and sewage pipe networks are already arranged in the city, and when a set of initial rain pipe network is newly built, the construction difficulty is high, the period is also long, and the investment cost is also 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 at the moment, the rainwater is clear, the pollution degree is small, and the rainwater in the middle and later periods at the time can be directly discharged to a downstream pipeline or a natural water body through the rainwater branch pipe and the municipal rainwater pipe, 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, which can be understood as a sunny day or a light rainy day, and the second switch is controlled to be turned on at this time, so that the initial rain stored in the initial rain storage tank can be input into the initial rain collecting port, and the initial rain collecting port can optionally discharge a pair of initial rains according to the three manners, which is not described herein again.

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. 4 (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. In addition, those skilled in the art can understand that the scheme of modifying the existing septic tank located on the rainwater branch pipe into the initial rain storage tank is completely the same as the above-described modified scheme of the existing septic tank located on the sewage branch pipe, and the scheme and principle of modifying the septic tank located on the rainwater branch pipe into the initial rain storage tank are not described in detail, and the above-described modified scheme of the septic tank located on the sewage branch pipe can be directly referred to.

In summary, in the rainwater treatment equipment based on the septic tank improvement provided by the utility model, the primary rain storage tank in the equipment is directly formed by improving the existing septic tank, when the equipment is used for a drainage system, the water inlet of the primary rain storage tank is communicated with the rainwater branch pipe, the water inlet of the primary rain storage tank is provided with the first switch, and the water outlet of the primary rain storage tank is communicated with the primary rain collecting port for outputting primary rain, so that the primary rain in the rainwater branch pipe flows into the primary rain storage tank formed by improving the septic tank for storage when the first switch is turned on, and the primary rain in the primary rain storage tank formed by improving the septic tank flows into the primary rain collecting port for discharge when the second switch is turned on; it can be understood that in this processing procedure, directly reform transform current septic tank into the first rain regulation pond of carrying out the regulation to first rain, compare in directly abandonment septic tank or landfill, avoided very big wasting of resources, also very big reduction simultaneously leads to reforming transform the cost increase owing to measures such as landfill, have implement simple transformation with low costs, implement simple, the wide characteristics of adaptability.
