Description

Pipe network system based on rain and sewage diversion

Technical Field

The invention belongs to the technical field of municipal drainage, and particularly relates to a pipe network system based on rain and sewage diversion.

Municipal drainage systems in cities are mainly divided into combined drainage systems and split drainage systems. The earliest combined drainage system mixes sewage, industrial wastewater and rainwater in the same canal, directly discharges the sewage into a water body nearby without any treatment, and is easy to cause serious pollution to the received water body. The split-flow drainage system is a system for respectively draining domestic sewage, industrial wastewater and rainwater in two or more independent pipelines.

Currently, in the existing municipal drainage technology, most of the confluence districts have the following problems:

(1) in rainy days, the rainwater is divided into primary rain and middle and later stage rain according to a time-length method, a water quality method or a liquid level method, 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, a large amount of mixed water of sewage and rainwater cannot be contained, if the sewage pipe is modified, the cost is 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.

(2) In the pipeline system in the confluence zone, rainwater and sewage are not discharged to realize rainwater and sewage diversion, so that on one hand, in rainy days, a large amount of sewage is mixed in rainwater flowing out of the confluence branch pipe, and at the moment, if the part of sewage is conveyed to a municipal rainwater pipe, the natural water connected with the municipal rainwater pipe is easily polluted; in the confluent branch pipe of another aspect lasting there is influent sewage and rainwater, sewage at this moment is diluted by the rainwater, but pollutant concentration among them is still higher, consequently, the middle and later stage rainwater that flows out from the confluent branch pipe is also sewage, still can cause the nature water to be polluted environment in flowing into municipal rainwater pipe with middle and later stage rainwater, and when carrying this middle and later stage rainwater to municipal sewer pipe, again because the volume of middle and later stage rainwater is great, and municipal sewer pipe's capacity is limited, can not hold middle stage rainwater or later stage rainwater, if reform transform municipal sewer pipe, must cause the cost too high, and the great sewage treatment plant that sends into of the volume of middle stage rainwater or later stage rainwater that mixes domestic sewage handles, also can cause sewage capacity not enough, or processing resources waste.

Therefore, in the existing municipal drainage technology, rainwater and sewage are not distributed in a combined system cell in a rainy day for treating and discharging rainwater, so that the treatment pressure of a treatment facility is high, the treatment facility runs in an overload mode, the service life of the treatment facility is shortened, and the technical defect of dry riverway is caused under the condition that no water is supplemented along the riverway due to insufficient water treatment discharge amount in a fine day.

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.
