Experiment system for low impact development facility water quality simulation

Abstract

The invention relates to an experiment system for low impact development facility water quality simulation. The experiment system comprises an LID facility water quality simulation unit, an artificial rainfall control unit and a sample collection unit, wherein the LID facility water quality simulation unit comprises an experiment box (12) and an LID facility, the experiment box (12) and the LID facility are arranged in a side-by-side manner, the top portion of the experiment box (12) is opening, the LID facility is arranged inside the experiment box (12) and is communicated to the sample collection unit, the artificial rainfall control unit comprises a mixing assembly, a water supply assembly and a spraying assembly, the mixing assembly, the water supply assembly and the spraying assembly are sequentially connected through water conducting pipes (4), and the spraying assembly is arranged above the experiment box (12), and is arranged opposite to the LID facility. Compared with the experiment system in the prior art, the experiment system of the present invention has advantages of simple structure, convenient operation, economy and practicality, and is suitable for the low impact development facility water quality simulation research in the room, and further has the water amount simulation function.

Description

technical field [0001] The invention belongs to the technical field of urban rainwater management and control systems, and relates to laboratory simulation equipment used in low-impact development facilities for the treatment of rainfall water quality, in particular to an indoor experiment involving rainfall formation and its flow generation and water quality simulation of low-impact development facilities system. Background technique [0002] In recent years, the rapid development of urbanization has led to an increase in the proportion of urban surface impervious areas, which has changed the urban hydrological cycle. In particular, while causing runoff volume and peak flow to increase, it also pollutes the surrounding environment. As a result, relatively new stormwater management techniques such as low-impact development, sustainable urban drainage systems, and water-sensitive urban design have been developed in different countries. In China, the construction of "sponge ...

AI Technical Summary

Problems solved by technology

In the literature and patents reported so far, there are few experimental devices for water quality simulation of low-impact development facilities. At the same time, the migration and transformation mechanism of pollutants in water bodies in LID facilities is unclear, so it is urgent to design and build corresponding experimental devices for research.
