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, municipal administration conflux pipe 34, sewage branch pipe, municipal administration downspout, municipal administration sewage pipe all can use same kind of pipeline, perhaps different kind of pipeline, perhaps the same, the pipeline that partly is different, this the utility model discloses do not do the injecing, as long as can realize the pipeline that liquid was carried, all be applicable to the utility model discloses, also all be within the protection scope. As for the dirty water and the clean water referred to in this embodiment 3, the dirty water may be domestic sewage, or primary rain, or mixed water of domestic sewage and primary rain; "clean water" is understood to mean late-stage rainwater. Specifically, for the rainfall period, the rain water can be divided into the first rain and the middle and later rain, and the division manner 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 rain water is the first rain at the early stage of the rainfall, and the corresponding rain water is the middle and later rain at the middle and later stages 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.
The method for determining the specific mode of the initial rain or the middle and later rain is not limited, and the determination can be selected according to the actual operation requirement; in other words, any of the above-mentioned manners of determining the initial rain or the middle and later rain is applicable to the present invention.
Of course, those skilled in the art should understand that, because there is a certain error also allowed in the discharging process of rainwater and/or sewage in the actual operation process, there may be a certain error in the specific division of each period, for example, there is a division node that is not strict in the middle of the first rain and the middle and later rain, and the middle and later rain is mixed with the middle and later rain, or the first rain/middle and later rain is mixed with a small amount of sewage, etc., so that there is an error in the division of "clean water" and "dirty water", and the operation influence caused by this error is negligible and should not be considered as being out of the protection range of the present invention because it does not affect the implementation effect of the whole technical solution of the present invention.
