Abstract

The invention discloses a plant retained element experimental apparatus for water quality and water yield three-dimensional simulation control, comprising a rainwater storage tank, a water pump, a water duct, a bracket, a shower nozzle, a porous water distribution plate, a raining hole, micropore clay pipes, an elbow, water content monitoring probes, an experimental soil bin, a water outlet pipe, a sampling bottle, a desk, a plug, a runoff pipe, a suction pipe, a runoff storage groove, a water content monitor, an automatic display screen, a regulating valve and a water content induction line. A lower outlet of the rainwater storage tank is connected with a water inlet of the water pump; the water outlet of the water pump is used for conveying artificial rainwater to the shower nozzle through the water duct, wherein the shower nozzle is connected with the other end of the water pump; the artificial rainwater is uniformly sprayed in the experimental soil bin via the porous water distribution plate; the micropore clay pipe is located at the middle part of the experimental soil bin and connected with the sampling bottle via the suction pipe, and the water outlet pipe is located at the bottom of the experimental soil bin; and the regulating valve arranged on the water content monitor can selectively connect to different water content monitoring probes and simultaneously display data of the water content of the point on the automatic display screen. The experimental apparatus is simple in structure, economic and practical.

Description

(1) Technical field [0001] The invention relates to a plant retention element experimental device for three-dimensional simulation control of water quality and water quantity. It is mainly used under the condition of simultaneous action of artificial rainfall and artificial runoff. The designed plant retention element not only simulates the three-dimensional water quality and water quantity migration process, but also can realize three-dimensional water quality. The dynamics study of the impact of water quantity belongs to the field of environmental engineering and ecological engineering. (2) Background technology [0002] The plant retention unit is an effective rainwater natural purification and disposal facility. Reduce flood peak flow, reduce rainwater discharge, and protect downstream pipelines, structures, and water bodies through stagnant storage; use plant interception and soil infiltration to purify rainwater and reduce pollution; make full use of runoff rainfall, c...

AI Technical Summary

Problems solved by technology

At present, the migration and transformation mechanism of pollutants carried by rainfall runoff in plant retention cells is not clear, especially the experimental research on three-dimensional water quality and water quantity is still in the preliminary research stage

Although domestic and foreign researchers have carried out some indoor and field experiments on water quality and quantity, they organically combined the artificial rainfall and artificial runoff device with the main facility of the three-dimensional plant retention experiment, that is, the experimental soil tank, to construct a three-dimensional plant under the condition of artificial rainfall and artificial runoff. There is no report on the experimental device for the simulation study of the water quality and quantity of the stagnant element.
