Abstract

The invention relates to the technical field of wetland filter material collection, and provides a sampling device, which is used for being pre-embedded in a subsurface flow wetland for sampling. The sampling device comprises a shell used for being pre-embedded in a subsurface flow wetland, and a plurality of filter material boxes which are sequentially arranged on the inner side of the shell in the height direction of the shell and are filled with a filter material. A plurality of water passing holes for water flow to pass through are formed in the shell in the height direction of the shell, and filter material holes corresponding to the water passing holes are formed in each filter material box. Filter material samples at different depths can be extracted only by taking out the filter material boxes from the shell, and fixed-point sampling can be realized without excavating a subsurface wetland filter material layer to take out the whole sampling device. Meanwhile, the sampling device disclosed by the invention can set monitoring points in different areas of the wetland according to research requirements, so that filter material samples in different areas and at different time in the wetland can be comprehensively obtained. The sampling device has the characteristics of convenience, flexibility and the like.

Description

technical field [0001] The invention relates to the technical field of wetland filter material collection, and in particular provides a sampling device. Background technique [0002] Wetland filter material is a kind of artificially combining one or several fillers (such as zeolite, gravel, soil, sand, cinder, limestone, etc.) in a certain proportion, through different combinations, and wetland plants and attached to the filter material. Microorganisms cooperate to complete the purification of sewage through complex physical, chemical and biological actions. [0003] During the operation of the wetland, the physical and chemical properties of the filter material will change significantly with time, especially the filter material at different positions and different depths due to the concentration of water pollutants received (such as organic pollutants, heavy metal elements, nitrogen, etc.) Phosphorus, sulfide, suspended solids, etc.), water dissolved oxygen content, and pl...
