Problems solved by technology

At present, there is a lack of more scientific and effective global system optimization design technology in this field. It is mainly based on the requirements of the control rate index of the source of runoff pollution, and the construction scale of various types of LID facilities is allocated subjectively, making it difficult to achieve a global optimal system design.
Therefore, in actual design and engineering practice, it is difficult to further realize the goal of saving environmental protection, green ecology, and low-carbon construction

Embodiment Construction

[0048] like figure 1 , 2 Shown: a kind of LID system design method based on improved PSO algorithm, comprises the following steps:

[0049] 1. Site selection analysis, that is, through the integration of 3S technology, analyze the underlying surface of the city from the perspective of current situation and planned land use, and identify the land use range and upper limit of the area where interception wells and storage tanks can be built. The specific steps are:

[0050] ① Determine the boundary of the design area;

[0051] ②Analyze and process the RS original image data of the urban underlying surface, and carry out identification and classification of the underlying surface;

[0052] ③ Use GPS on-site positioning to correct the recognition results of the underlying surface in step 2;

[0053] ④ Use the GIS platform to process and transform the results of step ③, and establish a current land use database based on the GIS platform;

[0054] ⑤ According to the planning map...

Abstract

An LID system design method based on an improved PSO algorithm comprises the following steps that (1) site selection analysis is conducted, specifically, by integrating the 3S technology, an urban underlying surface is analyzed from the aspects of the current situation and planned land, and the land range and the area upper limit which can be used for building an intercepting well and a storage pond are recognized; and (2) based on a site selection analysis result, secondary development is carried out on the SWMM model by adopting an improved PSO algorithm to finish LID facility arrangement and scale calculation. According to the method, the SWMM drainage model is subjected to secondary development by integrating the 3S technology and utilizing the improved PSO algorithm, and compared witha manual allocation accounting method, the method can determine the control index of the urban runoff pollution source with the minimum engineering investment.

Description

technical field [0001] The invention belongs to urban runoff pollution control methods, in particular to an LID system design method based on an improved PSO algorithm. Background technique [0002] Urban runoff pollution control is one of the core objectives of sponge city and black and odorous water treatment, and it is a key issue that needs to be solved to protect the water environment and achieve sustainable and green development of the social environment. LID system scheme design, as a means of source control, is one of the core tasks in the compilation of urban runoff pollution control scheme. At present, there is a lack of more scientific and effective global system optimization design technology in this field. It is mainly based on the requirements of the control rate index of runoff pollution sources, and the construction scale of various types of LID facilities is allocated subjectively, making it difficult to achieve a global optimal system design. Therefore, in...
