When one component is said to be "in communication with" another component, it can be directly connected to the other component or intervening components may be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the present invention.
Before describing the present invention, the following explanation is made for terms and terms related to the present invention, so as to enable those skilled in the art to understand the present invention more clearly and clearly, and further to support the technical problems to be solved and the technical effects to be achieved, and before describing the present invention:
a confluence branch pipe which is a pipe for transporting 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 used for conveying rainwater in a municipal pipeline; municipal sewage pipes are pipes used for conveying sewage in municipal pipelines.
It will be understood by those skilled in the art that the terms "storm water", "sewage", and "mixed water" are not intended to limit the "branch pipe" function, nor are the terms "municipal storm water", "municipal sewage", and "pipe" function, but are merely used for distinguishing purposes. In other words, the merging branch, the sewage branch, the municipal rainwater pipe, and the municipal sewage pipe may all use the same pipe, or different pipes, or partially the same and partially different pipes, but the present invention is not limited thereto, and any pipe capable of conveying liquid is suitable for the present invention, and is within the 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.
