Artificial wetland device for accurately grasping uniformly-collected water and internal mechanism

Abstract

The invention discloses an artificial wetland miniature simulation test device for accurately grasping uniformly-collected water and an internal mechanism, consisting of a water distribution device, artificial miniature simulation test blocks (quadruple blocks) and filler filling and sampling columns, wherein the water distribution device distributes water to the artificial miniature simulation test blocks and can ensure that the concentration of raw water in four test block boxes is consistent and the water inlet flow can be controlled according to the design ratio; and the different water outlet flows can be adjusted by each drain pipe. The artificial miniature simulation test blocks are used for filling filler, planting plants and the like so as to stimulate the composition of the artificial wetland, wherein the water level of the artificial miniature simulation test blocks can be adjusted and water samples can be taken out from four blocks. The filler filling and sampling columns are arranged in the test blocks (a plurality of sampling columns can be arranged in each test block) so as to realize the layered sampling of the filler. The artificial wetland miniature simulation test device can be used for investigating the parameter design and the treatment effect of the vertical current artificial wetland and designing and optimizing the vertical current artificial wetland and can realize the four-level simulation comparison of certain parameter under the same filler condition, the simulation comparison of four fillers under the same parameter condition as well as the layered sampling of the fillers.

Description

Technical field [0001] The invention belongs to the field of pollution control and ecological restoration, and relates to a micro-simulation test device for parameter setting and optimization of vertical subsurface flow constructed wetlands, which is used for parameter design and optimization of vertical subsurface flow constructed wetlands and micro-simulation for investigating the treatment effect of vertical subsurface flow constructed wetlands test device. Background technique [0002] At present, since the 1970s, many researches on constructed wetlands have been carried out at home and abroad. But so far, the constructed wetland test system is usually used as a black box, only focusing on the amount of water inflow and outflow, not much attention is paid to the water quality distribution along the course and at different depths, and little attention is paid to the course and sub-location of the distribution of filler characteristics , and it is only limited to analyzin...

AI Technical Summary

Problems solved by technology

[0003] Due to the fact that the existing conventional static simulation devices cannot regularly reveal the characteristics of the internal fillers in the system, it is difficult to accurately grasp the migration and transformation laws and mechanisms of pollutants in the system.
