Cage drawer type vertical subsurface flow constructed wetland simulator and wetland simulation method

Abstract

The invention provides a cage drawer type vertical subsurface flow constructed wetland simulator and a wetland simulation method and belongs to the wetland study technology. The cage drawer type vertical subsurface flow constructed wetland simulator is characterized by comprising a plurality of matrix columns (1) mounted in such a manner of stacking up and down, wherein each matrix column (1) is a container-shaped column with an opening at one end; a discharge pipe (2) is arranged on the outer sidewall, close to the bottom surface, of each matrix column; a sealing ring (8) is arranged at the edge of the bottom of each matrix column, and the upper edge of the opening of the matrix column is matched with the outer edge of the bottom in size and shape, so that the adjacent matrix columns (1) mounted in such the manner of stacking up and down can be hermetically connected with each other; no water hole is formed in the bottom of the matrix column (1) at the lowest position, and water holes (9) are formed in the bottoms of the other matrix columns (1). In the experimental process, water samples can be taken from the water outlet pipes, and meanwhile, the plurality of matrix columns can be split to obtain the matrices at different levels for analysis, and different wetland simulation matrices can be arranged in the different matrix columns to simulate the wetland system more flexibly.

Description

technical field [0001] The invention belongs to the technical field of ecological engineering, and relates to a cage-type vertical underflow artificial wetland simulation device and a wetland simulation method. Background technique [0002] At present, the use of vertical subsurface flow constructed wetlands to remove pollutants in water bodies to improve water quality for reuse of water resources has received widespread attention. Wetland substrates can remove pollutants through processes such as filtration, adsorption, precipitation, and ion exchange, and can also be used as The carrier of microorganisms uses the physical, chemical and biological interactions of microorganisms to remove pollutants in sewage through microbial decomposition and other processes. Therefore, in order to study the accumulation, distribution, transformation and migration of pollutants in the vertical subsurface flow constructed wetland water body in the wetland matrix, it is necessary to collect ...
