Description

Technical Field

[0001] The present invention belongs to the technical field of urban drainage system reconstruction and optimization, and specifically relates to an optimization method, system, equipment and storage medium for arranging the height of a discharge overflow weir. Background Art

[0002] In recent years, with the rise in global temperatures, the number of warm and humid air currents has continued to increase, and the frequency of extreme rainstorms has become increasingly high, resulting in poor operation of urban drainage systems, and frequent urban waterlogging and waterlogging problems. At the same time, the contribution of urban overflow pollution to water pollution has become increasingly prominent. Overflow sewage contains a variety of pollutants with high concentrations and strong impact, posing a serious threat to the quality of urban water environment. Therefore, the control of waterlogging and overflow pollution is imminent.

[0003] However, there is a certain contradiction between urban overflow pollution control and waterlogging control: overflow pollution control requires the drainage system to discharge less and slowly, so that sewage can be retained in the pipes; waterlogging control requires the drainage system to discharge more and faster, so that the accumulated water in the pipes can be discharged as much as possible and the pipe storage space can be increased. As a result, most existing technologies cannot solve the contradiction between urban overflow pollution control and waterlogging control, and often lose sight of one while focusing on the other, resulting in mediocre control effects and failure to solve practical problems.

BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 It is a flow chart of an optimization method for arranging the height of a discharge overflow weir in an embodiment of the present invention. DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0032] Example 1

[0033] This embodiment provides an optimization method for arranging the height of the overflow weir at the discharge port, such as Figure 1 As shown, the specific steps include:

[0034] Step 1: Obtain the predetermined analysis indicators and the original data of the analysis indicators under different rainfall and overflow weir height conditions.

[0035] Specifically, the analysis indicators include overflow reduction rate, overflow load reduction rate, water accumulation depth and water accumulation area.

[0036] In this embodiment, the urban drainage model constructed by Infoworks ICM software is used to simulate the original data of the analysis indicators under different rainfall and overflow weir height conditions. A certain area is taken as the target area, and the rainfall in this area is mostly moderate to heavy rain throughout the year. Therefore, three design rainfalls are selected for simulation when simulating the urban drainage model, namely moderate rain, heavy rain and heavy rain. At the same time, the overflow weir height is taken as the analysis object, and its proportion to the current pipe diameter is taken. Every 5% of the pipe diameter height is set as a working condition, and the maximum is 75% of the pipe diameter. The original data of the overflow reduction rate, overflow load reduction rate, water accumulation depth and water accumulation area under different rainfall and overflow weir height conditions are simulated by the urban drainage model, as shown in Table 1-3.

[0095] It can be seen that in moderate and heavy rain, the weir height of 75% pipe diameter ratio is better, in heavy rain, 60% pipe diameter ratio is better, and 75% pipe diameter ratio is second. The larger the comprehensive score index, the better the scheme. Based on the results of various rain types, the overflow weir height setting range is between 60% and 75% pipe diameter, and the best height is 75% pipe diameter ratio.
