The split-flow drainage system is a system for respectively draining domestic sewage, industrial wastewater and rainwater in two or more independent pipelines.

At present, in the existing municipal drainage technology, most of shunt system cells divide rainwater into primary rain and middle and later stage rain according to a time length method, a water quality method or a liquid level method in rainy days, and aiming at the discharge mode of the primary rain, the primary rain is generally directly shunted to a municipal sewage pipe and is recycled after being treated by a sewage treatment plant, however, the conveying capacity of the sewage pipe is limited, the sewage pipe cannot accommodate a large amount of mixed water of sewage and rainwater, if the sewage pipe is modified, the cost is inevitably too high, and when the mixed water mixed with the sewage and the primary rain is sent to the sewage treatment plant for treatment due to large amount, the capacity of the sewage treatment plant is insufficient, or the treatment resources are wasted; in addition, in sunny days, all the initial rain is treated and discharged in rainy days, and the water treatment discharge amount only relates to domestic sewage, so that the river is dried under the condition that no water is supplemented along the river due to insufficient water treatment discharge amount in long-term sunny days.

Also, in embodiments of the invention where an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. 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 rainwater branch pipe which is a pipe for transporting rainwater 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 above "storm water" and "sewage" are not limitations on the "branch pipe" function, nor are "municipal storm water" and "municipal sewage" 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.
