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

A homogeneous set of micro-simulation tests wetland water distribution apparatus and accurate knowledge of the internal mechanism. It consists of water distribution means, wetland micro grid simulation test (quadruple) and the filler member filling the three column sample composition. Water distribution apparatus embodiment of the wetland cell micro-simulation test with water, four trials to ensure consistency of the raw water tank cell concentrations, proportional control water flow according to design, each of the different drain water flow can be adjusted. Wetland micro grid simulation test tank filled packing plants grown to simulate wetland composition, the water level can be adjusted, respectively fourfold water samples taken. Packing filled column was placed in the test sample cell (each cell may be provided a plurality of test sample columns), the filler can be achieved stratified sampling. The apparatus may be used to examine the design parameter and the vertical flow wetland treatment effect for designing optimized vertical flow constructed wetlands, and four levels can be achieved under the same simulated conditions filler comparison of a parameter, the parameter under the same conditions of four kinds of filler analog comparator, and a filler to achieve a layered sample.
