Problems solved by technology

[0006] 1) The wind and waves in the lake are relatively strong, and the collection device tends to be tilted in the water, which will affect the collection efficiency of particulate matter
[0007] 2) Cannot collect particles of different depths or layers
[0008] 3) The underwater environment is complex, and the device is easily restricted by aquatic plants in the water body, causing damage

Abstract

The invention discloses a shallow lake suspended particulate matter collection device and a using method thereof. The collection device comprises a traction device, a trapping system and a stabilizing system. The traction device is connected with the upper portion of the trapping system. The traction device is used for controlling the placement depth of the trapping system in water. The trapping system comprises a trapping pipe and a trapping pipe support. The trapping pipe is used for collecting a water sample, the trapping pipe is fixed to the trapping pipe support, the lower end of the trapping pipe support is connected with the stabilizing system, and the stabilizing system stabilizes the trapping pipe at the preset height of water through gravity. The device has the advantages of being capable of being stabilized in shallow lakes and collecting particulate matter at different heights and different layers.

Description

technical field [0001] The invention belongs to the technical field of water environment, and in particular relates to a device for collecting suspended particles in shallow water lakes and a method for using the same. Background technique [0002] The particulate matter in the water body mainly comes from the particulate matter produced by the water body itself (plankton and its excrement and debris), the deposition of atmospheric particulate matter, the input of terrestrial and upstream particulate matter, and the resuspension of sediments. [0003] One of the biggest characteristics of shallow lakes is that the water-soil interface is constantly disturbed by wind and waves, causing a large number of surface sediments, animal and plant residues and other particulate matter to suspend and enter the water body again. It interacts with water bodies, thereby affecting water quality, nutrient levels and the ecological life of aquatic organisms. According to investigations and ...
