Design method of low impact development storm-water system

Abstract

The invention discloses a design method of low impact development storm-water system, and belongs to the technical field of low impact development storm-water treatment. The method includes selecting one or multiple water quality treatment methods and devices to perform water quality treatment for the storm-water from the storm-water water quality treatment methods and devices according to the concentration of the pollutant contained in the surface runoff of the storm-water and the size of the particulate matter, and selecting one storm-water water amount control method from storm-water water amount control methods according to the object of the storm-water treatment. The design method of the invention can reasonably design low impact development storm-water system according to the different objects of the storm-water treatment in the project and differences of specific storm-water water quality and water amount, can fully consider the effect, efficiency, and characteristic of each node facility in the system, can perform system efficiency-accounting for the whole technological process, and can effectively improve the perfectness and high effectiveness of the system based on the premise of guaranteeing purification quality of the water quality.

Description

technical field [0001] The invention relates to a design method of a rainwater comprehensive utilization system, belongs to the technical field of low-impact development rainwater treatment and control, and in particular relates to a design method of a low-impact development rainwater system. Background technique [0002] Using low-impact development technologies to manage stormwater is an important concept in the construction of sponge cities. In October 2014, the Ministry of Housing and Urban-Rural Development promulgated the "Technical Guidelines for Sponge City Construction - Construction of Rainwater System for Low-impact Development". An accurate and concise summary. Each technology described by these six words includes a variety of specific means in the field of real technology. According to the differences in the project's rainwater treatment objectives (surface runoff control rate) and the differences in the specific rainwater quality and quantity, the technical m...

AI Technical Summary

Problems solved by technology

First of all, this invention can only be used in the technical field of municipal engineering, so the generality is not strong, and the corresponding low-impact development rainwater treatment system cannot be designed according to the rainwater quality and quantity; secondly, the invention cannot be adapted to the actual environment according to the actual environment design of low-impact development stormwater systems; finally, the invention does not disclose a design method for low-impact development stormwater systems
