Integrated device for collecting and separating suspended particles of shallow lake

Abstract

The invention discloses an integrated device for collecting and separating suspended particles of a shallow lake. The integrated device comprises a locating system and a capturing and separation system, wherein the locating system comprises two big heavy punches, a buoy and a rope; the two big heavy punches are respectively connected with the buoy through the rope; the capturing and separation system comprises a capturing pipe and a capturing pipe bracket; the capturing pipe comprises a collecting hopper and a collecting bottle; the collecting bottle is connected below the collecting hopper; the collecting bottle is multifunctional and can be directly placed into a centrifugal machine for high-speed centrifugal separation; the capturing pipe bracket comprises a horizontal rod and a vertical rod which are fixed together to form a crossed shape; the capturing pipe is connected to the horizontal rod; and a small heavy punch is connected to the lower end of the capturing pipe bracket through the rope. The integrated device is simple in structure, low in cost, easy to process, long in service life and capable of collecting samples constantly for a long period of time.

Description

technical field [0001] The invention belongs to the technical field of water environment, and in particular relates to an integrated device for collecting and separating suspended particles in shallow lakes. Background technique [0002] Water pollution has become a worldwide environmental problem. In 2011, among the 26 nationally controlled key lakes (reservoirs) in China, the proportions of lakes (reservoirs) with water quality ranging from Grade IV to V and worse than Grade V were 50.0% and 7.7%, respectively. The increase of pollutant content in water is generally caused by two modes of action: exogenous input and endogenous release. When the external source is effectively controlled, the internal source effect becomes very obvious. 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 an...

AI Technical Summary

Problems solved by technology

[0004] Insufficiency of the existing technology: In the case of the same height, the cylindrical trapping device affects the collection efficiency of particulate matter, and at the same time, it is not suitable for lakes like Taihu Lake with strong winds and waves and an average water depth of less than 2 meters

After the suspended particles are collected, the preliminary separation of the water body and the suspended matter has not been achieved, which cannot provide convenience for the subsequent freeze-drying of the suspended matter

[0005] A heavy hammer cannot effectively prevent large wind and wave disturbances, which will cause the capture system to tilt, and eventually the suspended particles will be lost
