Description

Intelligent urban drainage method and system

Technical field

The invention relates to the field of urban drainage, and in particular relates to an intelligent urban drainage method and system.

Background technique

With the development of the urban economy, the urban area has expanded rapidly, and the urban drainage pressure has gradually increased. With the continuous addition of drainage pumping stations, how to improve the intelligentization of urban sewage drainage methods, energy conservation and emission reduction is becoming more and more important.

The task of urban drainage system planning is to discharge the sewage and rainwater from the entire city smoothly, and to treat the sewage well and meet the requirements of environmental protection. The main contents of the plan include: estimating the urban drainage, selecting the drainage system, designing the drainage pipeline, determining the sewage treatment method and the location of the urban sewage treatment plant, etc. The drainage system is an important infrastructure for modern cities, how to optimize the design and reconstruction of the economy and technology. The drainage system of the city is an important research topic. In the construction of municipal construction and environmental treatment projects, drainage systems often occupy a large proportion of investment. How to rationally design urban drainage system under various technical conditions that meet the requirements is an important issue in planning and design. Therefore, China has introduced urban drainage permit management measures to solve such problems.

From the perspective of environmental protection, drainage projects have the effect of protecting and improving the environment and eliminating the danger of sewage. Eliminating pollution and protecting the environment are indispensable conditions for economic construction and a major event to protect people's health and benefit future generations. From a health perspective, the construction of drainage projects has far-reaching significance for safeguarding people's health; First of all, water is an invaluable natural resource that is indispensable in all sectors of the national economy. Secondly, the proper treatment of sewage and the timely elimination of rain and snow are one of the necessary conditions to ensure the normal operation of industry and agriculture. At the same time, whether wastewater can be properly disposed of has an important impact on the development of new industrial production processes;

At present, almost all urban drainage pumping stations' collection wells, power cycle grille decontamination machines and harmful gas exhaust fans are routinely controlled to be turned on or off manually, and in accordance with existing operating procedures, to ensure operators The personal safety, power cycle grill decontamination machine and harmful gas exhaust fan must be synchronized with the drain pump operation. And some of the existing urban groundwater drainage pipes are old drainage pipes. When there is a long heavy rainstorm, due to the different drainage capacity of the drainage pipes in various areas of the city, large areas of water will be formed in areas with poor drainage capacity. Case. Moreover, when the displacement of the main drainage pipe in the city is constant, if the displacement of the regional sub-pipe is not coordinated, it is easy to cause water accumulation in the area where the drainage is required.

According to statistics of 258 cities in China in 1983, the average daily discharge of sewage from urban drainage pipes was 57.46 million cubic meters, of which 13.45 million cubic meters of domestic sewage, accounting for 23.4%. The amount of domestic sewage depends on the amount of domestic water. In the process of using domestic water, most of it becomes domestic sewage. Rainwater runoff is related to local storm intensity, catchment area and surface characteristics that produce runoff. The intensity of the storm used in the design of the drainage pipe depends on the design return period (the average age of repeated occurrences). Therefore, the value of the design return period affects the technical and economic effects of the project. The value is high, and the designed rainwater runoff is large, which will increase construction investment. However, in areas where important areas or short-term stagnant water can cause serious losses, the design return period should be higher.

Alternatively, when the water accumulation rate of the non-water storage area drainage pumping station is equal to 1, the drainage pump operating power of the non-water storage area drainage pumping station is no longer reduced or the drainage pump that is in the open state will be stopped.

Specifically, the water accumulation rate of the drainage pumping stations in each area is determined by the value of the water accumulation rate of the drainage pump stations in each area. When the water accumulation rate of the drainage pumping station in the water accumulation area is equal to 1 and the water intake amount of the drainage pumping station is less than the maximum water intake amount of the pre-stored drainage pumping station, it can be judged that there is no more water in the water accumulation area, and the non-product is no longer reduced. The working power of the drain pump of the water pumping station or the drain pump that will be turned off is turned off. When the water accumulation rate of the non-water-storing area drainage pumping station is equal to 1, it can be judged that if the non-water-storing area reduces the displacement, water accumulation may occur, so the drainage pump working power of the non-storage area drainage pumping station will no longer be reduced. The open drain pump is turned off.

In the above embodiment, by judging the water accumulation in various areas of the city, when the total displacement of the city reaches the limit value, it is necessary to reduce the displacement of the drainage pump station in the non-water accumulation area to allow space to increase the displacement of the drainage pump station in the water accumulation area. To reduce the accumulation of water in the stagnant water area, when the total displacement of the city does not reach the limit value, it is only necessary to increase the displacement of the drainage pumping station in the stagnant water area to reduce the problem of water accumulation in the stagnant water area. When the total displacement of the city reaches a limit value, if the displacement of the non-water-storing area is not reduced, the displacement of the water-storing area cannot be increased. Therefore, when the displacement of the controlled water-storage area increases, the displacement of the non-water-storing area should also be reduced. However, it is not possible to reduce the displacement of the non-water-storing area and the unrestricted increase of the displacement of the water-storing area, and to analyze and judge the limit to be controlled by the water accumulation rate of the water-storing area and the non-water-storing area, and avoid exceeding the limit. This causes the non-watershed area to become a stagnant water area.
