Description

Adjustment and storage equipment and storage device for drainage system

technical field

The invention belongs to the technical field of municipal drainage, and in particular relates to a regulation and storage device and a regulation and storage device for a drainage system.

Background technique

The municipal drainage equipment in the city is mainly divided into the combined drainage equipment and the divided drainage equipment. The earliest combined drainage equipment was to mix sewage, industrial waste water and rainwater in the same pipe, and directly discharge it into the water body without any treatment, which is easy to seriously pollute the receiving water body. Diversion system drainage equipment is a device that discharges domestic sewage, industrial waste water and rainwater in two or more independent pipes.

At present, in the existing municipal drainage technology, in the rainy days of most of the combined communities, the rainwater is divided into the first rain and the middle and later rain according to the duration method, the water quality method, or the liquid level method. The rain discharge method is generally to divert the first rain directly to the municipal sewage pipe, and then reuse it after being treated by the sewage treatment plant. However, the transportation capacity of the sewage pipe is limited, and it cannot accommodate a large amount of mixed water of sewage and rainwater. It will inevitably lead to high cost, and when the mixed water mixed with sewage and early rain is sent to the sewage treatment plant for treatment due to the large amount, it will also cause insufficient capacity of the sewage treatment plant or waste of treatment resources; in addition, on sunny days , Since the first rain has been treated and discharged in rainy days, the water treatment discharge only involves domestic sewage, so in case of long-term sunny days due to insufficient water treatment discharge, it is very easy to cause no water supply along the river course, and the occurrence of the river course dry up.

It can be seen that in the existing municipal drainage technology, there is a high pressure and overload operation for the sewage treatment plant in the rainy days for the confluence system, which reduces the service life of the treatment facilities and waste of resources, and also increases the amount of sewage. Pipeline conveying pressure and conveying strength, and the renovation of sewage pipelines will inevitably increase the cost, and on sunny days, due to insufficient water treatment discharge, it is easy to cause no water replenishment along the river, and the technical defect of the river drying up occurs.

Confluence branch pipes are pipes used to transport rainwater, sewage or mixed water of rainwater and sewage in unit area pipes; sewage branch pipes are pipes used to transport sewage in unit area pipes; municipal rainwater pipes are used in municipal pipes Pipes used to transport rainwater; municipal sewage pipes are pipes used to transport sewage in municipal pipelines.

Those skilled in the art can understand that the above-mentioned "rainwater", "sewage" and "mixed water" do not limit the function of "branch pipe", and "municipal rainwater" and "municipal sewage" do not limit the function of "pipe" either. , but only for distinction. In other words, the confluence branch pipe, sewage branch pipe, municipal rainwater pipe, and municipal sewage pipe can all use the same kind of pipe, or different kinds of pipes, or some of the same and some of different pipes, which is not limited in the present invention, as long as the liquid can be realized The conveying pipelines are all applicable to the present invention and are also within the protection scope of the present invention.

According to whether the rainfall behavior occurs, the period involved in the present invention can be divided into a rainfall period and a non-raining period, wherein the rainfall period refers to the period when the rainfall behavior occurs, which can be understood as a rainy day; A period of opposites refers to a period when no rainfall behavior occurs, which can be understood as a sunny day. Or according to the size of the rainfall, the period involved in the present invention can also 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, which can be understood as when the rainfall is slightly larger. The non-raining period is a period opposite to the rainfall period, which refers to the period when the rainfall is less than the rainfall threshold, which can be understood as the period when there is no rainfall or the rainfall is small.

During the process, in order to connect with the municipal pipeline, some branch pipes extend outside the unit area or municipal roads, which are also applicable to the present invention, which is not limited in the present invention. The confluence branch pipe 1 is communicated with the rainwater inlet 3 for conveying rainwater, so that the first rain and middle and late rain in the rainy period will be transported after being merged into the confluence branch pipe 1 through the rainwater inlet 3. It can be understood that the number of the rainwater inlets 3 can be multiple, In addition, the distribution positions of the plurality of rainwater inlets 3 in the unit area can be any position, and can be reasonably set according to the actual rain accumulation position in the actual process, which is not limited in the present invention. The sewage branch pipe 2 is connected with the municipal sewage pipe 10, so that the sewage in the unit area is first collected into the sewage branch pipe 2, and then the sewage branch pipe 2 transports the sewage to the confluence branch pipe 1; the municipal sewage pipe 10 can be connected to the sewage treatment facility 12 (such as a sewage treatment plant), the sewage is treated by the sewage treatment facility 12 and then discharged.
