Automatic green roof rainfall runoff pollution simulation device

Abstract

The invention discloses a green roof simulation complete device composed of an automatic rainfall part, a green roof simulation part and an automatic sampling part, and belongs to the field of non-point source pollution control. The device mainly comprises: 1) the automatic rainfall part, wherein an Arduino electronic prototype platform is used as a control panel, and cooperates with a motor control element to realize automatic control of rainfall intensity and rainfall duration; 2) the green roof simulation part divided into a vegetation layer, a soil matrix layer, a permeable filter layer and a water drainage and storage layer from top to bottom, wherein the soil matrix layer and the vegetation layer can be automatically regulated and cooperatively used according to local conditions; and3) the automatic sampling part which can realize timing sampling and automatic tube replacement through a control circuit. The automatic rainfall part can automatically rain and supplement water in the dry season, the most suitable soil matrix thickness, vegetation types and the like are found through experimental research of the green roof simulation part, and biological monitoring and water quality research are carried out through the automatic sampling part. The whole process does not need to spend much manpower, and regulation of roof runoff can be achieved by one person.

Description

technical field [0001] The invention relates to the field of non-point source pollution control, in particular to a simulation device for fully automatic rainfall runoff pollution on a green roof. Background technique [0002] As a complex community gathering place, a city has complex components. When natural rainfall forms runoff and flows through the city through different channels, the rainwater washes away the pollutants accumulated on the surface and then enters the urban river in the form of surface overflow. The pollutants include atmospheric Wet and dry deposition, organic waste of animals and plants, etc. Rainwater outlets have become an important source of urban surface water pollution caused by urban non-point source pollution entering urban rivers. In order to control urban runoff pollution, source control, including the reconstruction of typical urban underlying surfaces, becomes the first step. Among them, the roof is an important part of the urban underlying...
